Description

Technical Field

[0001] The present application belongs to the field of project management technology, and in particular, relates to a method, system and medium for identifying risks in surveying and mapping projects. Background Art

[0002] The surveying and mapping project uses various surveying and mapping technologies to measure and record spatial geographic information of the earth's surface or a specific area, including geographical environmental elements such as terrain, landforms, buildings, roads and water systems, and provides detailed geographic surveying and mapping data for various infrastructure construction projects, so that decision makers can carry out effective planning and design based on geographic surveying and mapping data.

[0003] With the rapid development of the geographic information industry, surveying and mapping projects are playing an increasingly important role in urban planning, land management, resource exploration and other fields. However, due to the growing demand for infrastructure, transportation networks and urban expansion in provinces, cities and counties, the number of surveying and mapping projects has become increasingly large and the scope of coverage has become increasingly wide, resulting in a sharp increase in the amount of data that the regulatory authorities of surveying and mapping projects need to process and analyze. The supervision of a large number of surveying and mapping projects not only consumes a lot of manpower and material resources, but also makes it difficult to quickly identify surveying and mapping projects that need to be focused on, resulting in low efficiency in the supervision of surveying and mapping projects.

[0004] Based on this, how to identify high-risk surveying and mapping projects from a large number of surveying and mapping projects, implement targeted supervision of surveying and mapping projects, and improve the efficiency of supervision of surveying and mapping projects is an important issue that needs to be urgently addressed.

It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0063] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0064] To facilitate the understanding of the technical solutions provided by the present application, the relevant terms in the present application are explained before the specific embodiments, as follows:

[0065] Integration of multiple surveys into one: refers to the integration of multiple surveying and mapping matters involved in the four stages of the entire construction application process (project approval, planning permission, construction permission, and completion acceptance) of engineering construction projects into a comprehensive joint surveying and mapping project, thereby improving the efficiency and quality of surveying and mapping work and reducing enterprise costs.

[0066] 3σ principle: It is a statistical principle used in quality control and data analysis. It is based on the concept of normal distribution and believes that most errors in data are random, while errors beyond a certain range are regarded as outliers.

[0067] The embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0068] The following embodiments of the present application provide a method for identifying risks of surveying and mapping projects, which obtains projects to be supervised that include at least initial risk projects, quickly extracts initial risk projects that are prone to regulatory risks in the current surveying and mapping project set, and builds a risk project supervision library based on the projects to be supervised, so as to facilitate the supervision of each risk project in the risk project supervision library. This achieves the rapid identification and extraction of surveying and mapping projects with regulatory risks from massive surveying and mapping projects, and the targeted supervision of surveying and mapping projects with regulatory risks, thereby improving the rationality of the allocation of supervision resources and the efficiency of supervision of surveying and mapping projects.

[0069] See also Figure 1 , showing a flow chart of a surveying and mapping project risk identification method provided by the present invention in a first embodiment.

[0070] like Figure 1 As shown, in this embodiment, the surveying and mapping project risk identification method provided by the present invention includes the following steps:

[0071] Step S1, obtaining the projects to be supervised in the current surveying and mapping project set; the projects to be supervised include at least: initial risk projects; the initial risk projects are surveying and mapping projects in the current surveying and mapping project set that meet at least one of several preset risk determination rules;

[0072] The preset risk determination rules include price risk determination rules, credit risk determination rules and / or business capability determination rules.

[0073] Optionally, the method for obtaining the initial risk projects includes: performing risk project determination on each surveying and mapping project according to a number of preset risk determination rules, and based on the determination results, extracting surveying and mapping projects that meet at least one of the several preset risk determination rules from the current surveying and mapping project set as initial risk projects.

[0074] Optionally, the preset risk determination rules include at least one of low-price project determination rules, negative contractor determination rules, user low-evaluation contractor determination rules, review department low-evaluation contractor determination rules, low-quality contractor determination rules and first-test contractor determination rules.

[0075] Optionally, the low-price project determination rule includes: the contract unit price of the surveying and mapping project is less than a price threshold.

[0076] Exemplarily, the project information of the surveying and mapping project includes the contract unit price. When the preset risk determination rule includes the low-price project determination rule, the method of obtaining the project to be supervised includes: extracting the contract unit price of the surveying and mapping project, and detecting whether the contract unit price of the surveying and mapping project is less than the price threshold; if so, determining that the surveying and mapping project is the initial risk project.

[0077] See also Figure 2 , showing a flow chart of the sub-steps in step 1 of a surveying and mapping project risk identification method provided by the present invention in an embodiment;

[0078] like Figure 2 As shown, in one implementation, the method for obtaining the price threshold includes:

[0079] Step S11, obtaining the contract unit price of each surveying and mapping project in the current surveying and mapping project set;

[0080] Step S12: Calculate the mean value and standard deviation of the contract unit price based on the contract unit prices.

[0081] Optionally, the method for calculating the average contract unit price is as follows:

[0082]

[0083] In the above formula, μ represents the average unit price of the contract, U i represents the i-th contract unit price, and n represents the total number of contract unit prices.

[0084] Optionally, the calculation method of the contract unit price standard deviation is as follows:

[0085]

[0086] In the above formula, σ represents the standard deviation of the contract unit price; μ represents the mean of the contract unit price, U i represents the i-th contract unit price, and n represents the total number of contract unit prices.

[0087] Step S13: Based on the mean value of the contract unit price and the standard deviation of the contract unit price and based on a mathematical statistics method, the price threshold is obtained.

[0088] The price threshold is the price at which the contract unit price is abnormal.

[0089] Optionally, the anomaly in the contract unit price is the risk of low-price competition.

[0090] Optionally, the mathematical statistics method is the 3σ principle, and obtaining the price threshold based on the mathematical statistics method includes: calculating the difference between the mean of the contract unit price and 3 times the standard deviation of the contract unit price as the price threshold.

[0091] The surveying and mapping project risk identification method provided in this embodiment obtains the inherent rules of the contract unit price distribution of each surveying and mapping project based on the principles of mathematical statistics, reduces the interference of human factors on the set price threshold in a data-driven manner, and realizes accurate screening of low-priced surveying and mapping projects based on the price threshold obtained in a data-driven manner. It can not only adapt to the identification needs of low-priced surveying and mapping projects in different regions and different types of surveying and mapping businesses, but also be applicable to market environments with various price fluctuations.

[0092] It should be noted that low-priced surveying and mapping projects are prone to involve low-price competition among various contractors, and the low-price advantage of the contractors is usually achieved by adopting low-quality surveying and mapping instruments and / or unqualified surveying and mapping personnel, thereby reducing the surveying and mapping costs of the contractors. This leads to quality problems in the surveying and mapping data obtained by the low-price competing contractors.

[0093] Optionally, the negative contractor determination rule includes: the amount of historical negative information of the contractor is greater than a preset quantity threshold; illustratively, the preset quantity threshold is 0.

[0094] Exemplarily, the project information of the surveying and mapping project includes historical negative information of the construction unit. When the preset risk determination rule includes the negative construction unit determination rule, the method for obtaining the initial risk project includes: extracting the historical negative information of the construction unit corresponding to the surveying and mapping project, detecting whether the amount of the historical negative information of the construction unit is greater than a preset amount threshold, and if so, determining that the surveying and mapping project is the initial risk project;

[0095] Optionally, the historical negative information includes negative information on unit qualifications and / or negative information on surveying and mapping personnel.

[0096] By way of example, the negative information on unit qualifications includes: (1) quality accidents, safety accidents or data leakage accidents that are identified as accidents of responsibility by the competent department and subject to administrative penalties; (2) major surveying and mapping and geographic information violations with a project amount of more than RMB 2 million, which are subject to administrative penalties by the competent department; (3) fraudulent application materials for surveying and mapping qualifications; (4) failure to meet the standards twice or more within five years in the "double random" inspections of surveying and mapping and geographic information at all levels or in the surveying and mapping quality inspections conducted by statutory quality inspection agencies; the "double random" inspections refer to the random selection of inspection objects and the random selection of law enforcement inspection personnel.

[0097] Exemplarily, the negative information about surveying and mapping personnel includes: (1) those who have committed serious acts of leaking secrets and have been subject to administrative penalties by the competent authorities; (2) those who are the main persons responsible for quality accidents and safety accidents and have been subject to administrative penalties by the competent authorities; (3) those who are the main persons responsible for major surveying, mapping and geographic information violations in their units; and (4) those who are the main persons in charge of units that have falsified materials in their application for surveying and mapping qualifications and those who are involved in the falsified materials.

[0098] Optionally, the rule for determining a construction unit with a low user rating includes: a user favorable rating of the construction unit is less than a preset favorable rating threshold.

[0099] Exemplarily, the project information of the surveying and mapping project includes historical user evaluation information of the construction unit. When the preset risk determination rule includes the user low-evaluation construction unit determination rule, the method for obtaining the initial risk project includes: extracting the historical user evaluation information of the construction unit corresponding to the surveying and mapping project, calculating the user favorable evaluation rate of the construction unit based on the historical user evaluation information, and detecting whether the user favorable evaluation rate is less than a preset favorable evaluation rate threshold. If so, determining that the surveying and mapping project is the initial risk project

[0100] Optionally, the rule for determining a construction unit with a low evaluation by the audit department includes: the historical evaluation level of the construction unit corresponding to the surveying and mapping project evaluated by the audit department is lower than a preset audit evaluation level.

[0101] Exemplarily, the project information of the surveying and mapping project includes historical audit department evaluation information of the construction unit. When the preset risk determination rule includes the determination rule of the construction unit with low evaluation by the audit department, the method of obtaining the initial risk project includes: extracting the historical audit department evaluation information of the construction unit corresponding to the surveying and mapping project, and based on the historical audit department evaluation information, detecting whether there is a surveying and mapping project among the surveying and mapping projects undertaken by the construction unit whose evaluation level by the audited department is lower than the preset audit evaluation level; if so, determining that the surveying and mapping project is the initial risk project.

[0102] Optionally, the low-quality contractor determination rule includes: unqualified inspection results exist in the inspection results of surveying and mapping projects undertaken by the contractor in the past N years.

[0103] Exemplarily, the project information of the surveying and mapping project includes historical sampling information of the construction unit. When the preset risk determination rule includes the low-quality construction unit determination rule, the method for obtaining the initial risk project includes: extracting the historical sampling information of the construction unit corresponding to the surveying and mapping project, and based on the historical sampling information, detecting whether there are unqualified sampling results in the sampling results of surveying and mapping projects undertaken by the construction unit in the past N years; if so, determining that the surveying and mapping project is an initial risk project; N is a positive integer.

[0104] In a specific embodiment, the sampling inspection results of the surveying and mapping projects undertaken by the construction unit in the past N years are the sampling inspection results of the surveying and mapping projects undertaken by the construction unit in the past 2 years.

[0105] Optionally, the first surveying and mapping contractor determination rule includes: the contractor undertakes a surveying and mapping project for the first time in the administrative area where the surveying and mapping project is located and / or the contractor carries out surveying and mapping business corresponding to the surveying and mapping project for the first time.

[0106] Exemplarily, the project information of the surveying and mapping project includes historical construction information of the construction unit. When the preset risk determination rule includes the first-survey construction unit determination rule, the method for obtaining the initial risk project includes: extracting the historical construction information of the construction unit corresponding to the surveying and mapping project, and based on the historical construction information, detecting whether the construction unit is a first-survey unit, and if so, determining that the surveying and mapping project is the initial risk project;

[0107] Among them, the first surveying unit is the unit that undertakes the surveying and mapping project for the first time in the administrative area where the surveying and mapping project is located, and / or the unit that carries out the surveying and mapping business corresponding to the surveying and mapping project for the first time.

[0108] Step S2: construct a risk project supervision library based on the projects to be supervised; the risk project supervision library includes various risk projects to be supervised.

[0109] Optionally, the step of constructing a risk project supervision library based on the project to be supervised includes:

[0110] According to several preset compliance verification rules, compliance verification is performed on each of the projects to be supervised to obtain a first risk project; based on the first risk project, the risk project supervision library is constructed; the first risk project is a surveying and mapping project that does not meet at least one of the preset compliance verification rules.

[0111] Optionally, the preset compliance verification rules include: at least one of: resource compliance verification rules, format standardization verification rules, data completeness verification rules, data consistency verification rules and content rationality verification rules.

[0112] Optionally, the resource compliance verification rules are used to verify whether the actual surveying and mapping resource information of the surveying and mapping project complies with regulatory requirements.

[0113] In one embodiment, the regulatory provisions include: the actual surveying and mapping resource information of the surveying and mapping project is consistent with the corresponding registered surveying and mapping resource information, then the resource compliance verification rules include: the actual surveying and mapping resource information of the surveying and mapping project is consistent with the corresponding registered surveying and mapping resource information.

[0114] Optionally, the actual surveying and mapping resource information is obtained based on an acceptance report corresponding to the surveying and mapping project.

[0115] Optionally, the surveying and mapping resource information includes: surveying and mapping personnel information and surveying and mapping instrument information; the surveying and mapping personnel information includes: the surveying and mapping personnel's name and / or professional qualification certificate number, etc.; the surveying and mapping instrument information includes: the name and / or model of the surveying and mapping instrument, etc.

[0116] In a specific embodiment, the method for obtaining the actual surveying and mapping resource information includes:

[0117] Character recognition technology is used to perform character recognition on the acceptance report corresponding to the surveying and mapping project to obtain the name and / or professional qualification certificate number of the surveying and mapping personnel of the surveying and mapping project, and the name and / or model of the surveying and mapping instrument.

[0118] Optionally, the character recognition technology includes: optical character recognition technology.

[0119] Exemplarily, the project information of the surveying and mapping project includes surveying and mapping personnel information and surveying and mapping instrument information. When the preset compliance verification rule includes: resource compliance verification rule, the implementation method of performing compliance verification on each of the projects to be supervised includes:

[0120] Obtaining an acceptance report corresponding to the surveying and mapping project; using character recognition technology to perform character recognition on the acceptance report to extract surveying and mapping personnel information and surveying and mapping instrument information from the acceptance report;

[0121] The surveying and mapping personnel information and the surveying and mapping instrument information are detected to see whether they correspond to the registered surveying and mapping personnel information and the registered surveying and mapping instrument information. If not, it is determined that the surveying and mapping project does not meet the resource compliance verification rules.

[0122] Optionally, the format standardization verification rule includes: the data formats of various surveying and mapping data in the surveying and mapping project are respectively consistent with corresponding preset data formats.

[0123] Optionally, the data completeness verification rule includes: the total number of items of surveying and mapping data in the surveying and mapping project is equal to a preset total number of items.

[0124] Optionally, the data consistency verification rule includes: each item of surveying and mapping data in the surveying and mapping project corresponds to surveying and mapping data approved by the review department.

[0125] It should be noted that in the supervision of surveying and mapping projects, especially in the supervision of surveying and mapping projects involving "multiple surveys in one", the surveying and mapping data submitted by the contractor must be consistent with the surveying and mapping data approved by the review department, so as to avoid the situation where the contractor submits surveying and mapping data that meets the first indicator when the review department approves the first indicator in the first stage, and then resubmits the modified surveying and mapping data that meets the second indicator but does not meet the first indicator when the review department approves the second indicator in the second stage. For example, when the review department approves the greening area indicator, the contractor submits surveying and mapping data that meets the requirements of the greening area indicator, and when the review department approves the parking space area indicator, the contractor resubmits the surveying and mapping data that is modified from the greening area to the parking space area, so that the modified surveying and mapping data can pass the review department's approval of the parking space area indicator.

[0126] Optionally, the content rationality verification rules include: each item of surveying and mapping data in the surveying and mapping project meets corresponding data planning requirements.

[0127] Exemplarily, when the data planning requirement includes that the floor area ratio is greater than a preset floor area ratio threshold, the floor area ratio in each surveying and mapping data in the surveying and mapping project is greater than the preset floor area ratio threshold.

[0128] In this embodiment, the surveying and mapping project risk identification method provided by the present application constructs a number of preset compliance verification rules, and performs compliance verification on each of the projects to be regulated according to each of the preset compliance verification rules. Among the projects to be regulated, the surveying and mapping projects that do not meet at least one of the preset compliance verification rules are extracted as risk projects, thereby realizing the rapid identification and extraction of surveying and mapping projects with regulatory risks from a large number of projects to be regulated, so as to facilitate accurate targeted supervision of surveying and mapping projects with regulatory risks, and further improve the rationality of allocation of regulatory resources and the efficiency of supervision of surveying and mapping projects.

[0129] When the projects to be supervised only include the initial risk projects, the step of constructing a risk project supervision library based on the projects to be supervised further includes:

[0130] Based on the projects to be supervised, the total number of preset selected projects and the selection ratio of projects in each region, an initial project selection is performed to build a risk project supervision library based on the initially selected projects to be supervised; the initial project selection includes:

[0131] Based on the preset total number of selected projects and the selection ratio of projects in each region, calculate the number of projects to be selected in each region respectively;

[0132] Selecting the projects to be supervised corresponding to the number of selected regional projects in each first-level administrative region; building the risk project supervision library based on the selected projects to be supervised;

[0133] Among them, the regional project selection ratio is the ratio of the number of the projects to be supervised located in the first-level administrative region to the total number of the projects to be supervised; the first-level administrative region is the secondary administrative region of the administrative region where each of the surveying and mapping projects is located.

[0134] See also Figure 3 , showing a flow chart of step 2 of the surveying and mapping project risk identification method provided in the present application in one embodiment;

[0135] like Figure 3 As shown, in one embodiment, after building the risk project supervision library, the method further includes:

[0137] Step S22: according to the risk determination rules satisfied by each of the unqualified items, obtain the number of the unqualified items corresponding to each of the risk determination rules; calculate the ratio of the number of the unqualified items corresponding to each of the risk determination rules to the total number of the unqualified items, as the proportion of the unqualified rule items corresponding to each of the risk determination rules;

[0138] Step S23: Based on the proportion of unqualified rule projects and the remaining projects to be supervised, a proportion project selection is performed on the remaining projects to be supervised in each of the first-level administrative regions, so as to add each selected project to be supervised to the risk project supervision library; the remaining projects to be supervised are projects to be supervised other than the risk projects in the current risk project supervision library; the proportion project selection includes:

[0139] In the first-level administrative region, based on the number of regional projects selected in the first-level administrative region and according to the proportion of unqualified rule projects corresponding to each type of rule, the projects to be supervised that meet the corresponding risk determination rules are respectively selected.

[0140] It should be noted that the higher the proportion of unqualified projects corresponding to each type of rules, the higher the proportion of surveying and mapping projects that meet this type of risk determination rules among the unqualified projects, that is, the higher the probability of supervision failure of the surveying and mapping projects that meet this type of risk determination rules, and the higher the supervision risk.

[0141] In this embodiment, the surveying and mapping project risk identification method provided by the present application performs initial project selection in the projects to be supervised, so as to select the projects to be supervised according to the regional project selection ratio from a large number of projects to be supervised according to the first-level administrative region where the projects to be supervised are located and the total number of preset selected projects, and constructs a risk project supervision library based on the initially selected projects to be supervised, so as to reasonably allocate the supervision resources of each first-level administrative region according to the proportion of projects in each first-level administrative region; and, after constructing the risk project supervision library, the method obtains unqualified projects based on the supervision results of each risk project in the current risk project supervision library; obtains the proportion of unqualified rule projects corresponding to each type of rule based on the risk determination rules that each unqualified project satisfies; based on the proportion of unqualified rule projects and the remaining projects to be supervised, for the remaining projects to be supervised in each first-level administrative region, according to the proportion of unqualified rule projects, the number of selected surveying and mapping projects that meet the corresponding risk determination rules is allocated, so as to improve the accuracy of selecting unqualified projects from the remaining projects to be supervised and reasonably allocate supervision resources.

[0142] The surveying and mapping project risk identification method provided in the above embodiment obtains the projects to be supervised including at least the initial risk projects, quickly extracts the initial risk projects that are prone to regulatory risks in the current surveying and mapping project set, and constructs a risk project supervision library based on the projects to be supervised, so as to facilitate the supervision of each risk project in the risk project supervision library. It realizes the rapid identification and extraction of surveying and mapping projects with regulatory risks from massive surveying and mapping projects, and the targeted supervision of surveying and mapping projects with regulatory risks, thereby improving the rationality of the allocation of supervision resources and the efficiency of supervision of surveying and mapping projects.

[0144] like Figure 4 As shown, the surveying and mapping project risk identification method provided by the present invention, after obtaining the first risk project, further includes:

[0145] Step S3, based on the spatial distribution relationship between each of the first risk projects and the administrative regions, count the number of the first risk projects located in each of the administrative regions, and take the administrative region with the largest number of projects as the target administrative region; obtain other surveying and mapping projects in the current surveying and mapping project set except the initial risk project, extract the second risk project from other surveying and mapping projects in the target administrative region, and add the second risk project to the risk project supervision library;

[0146] Among them, the administrative regions are located at the same administrative level.

[0147] A surveying and mapping project risk identification method provided in the above embodiment obtains the target administrative area that is prone to the first risk projects based on the spatial distribution relationship between each first risk project and the administrative area, and obtains the second risk project based on each other surveying and mapping project in the target administrative area, thereby achieving further screening of each other surveying and mapping project in the target administrative area, and improving the comprehensiveness of extracting surveying and mapping projects with regulatory risks from the current surveying and mapping project set.

[0150] In one embodiment, the method for obtaining the sample inspection items includes:

[0151] From the other surveying and mapping projects in the current surveying and mapping project set except the initial risk project, a preset surveying and mapping project is selected as the sampling inspection project.

[0154] Step S11', obtaining the administrative area where each of the surveying and mapping projects is located as the administrative area to be selected;

[0155] Step S12', based on the administrative level of the current area to be selected, perform corresponding item sampling, including: detecting whether there is a secondary administrative area in the current administrative area to be selected, if not, perform random item sampling; if yes, perform regional item sampling.

[0156] In one embodiment, the random item selection is implemented by:

[0157] Randomly selecting the preset first number of surveying and mapping projects from other surveying and mapping projects in the current administrative area to be randomly selected as the sampling inspection projects;

[0158] Among them, the preset first number is less than the total number of other surveying and mapping projects in the current administrative area to be selected.

[0159] See also Figure 7 , showing a flow chart of sub-steps in step 12' of a surveying and mapping project risk identification method provided by the present invention in an embodiment;

[0160] like Figure 7 As shown, in one embodiment, the implementation method of the regional project selection includes:

[0161] Step S121', obtaining each sub-administrative region corresponding to the current administrative region to be selected and determining a preset second number corresponding to each sub-administrative region, and randomly selecting a preset second number of surveying and mapping projects from other surveying and mapping projects in each current sub-administrative region as regional selection projects;

[0162] The preset second number is smaller than the total number of other surveying and mapping projects in any current secondary administrative region.

[0163] Step S122', perform the compliance check on each of the current regional lottery items to obtain non-compliant regional lottery items in each of the current regional lottery items; count the total number of non-compliant regional lottery items in each of the current sub-administrative regions based on the spatial distribution relationship between the non-compliant regional lottery items and the current sub-administrative regions, and calculate the proportion of the number of non-compliant regional lottery items corresponding to each of the current sub-administrative regions based on the total number of non-compliant regional lottery items in each of the current sub-administrative regions;

[0164] The non-compliant regional lottery items are the regional lottery items that do not meet at least one of the preset compliance verification rules among the regional lottery items;

[0165] The proportion of the number of non-compliant area lottery projects corresponding to the current sub-administrative region is the ratio of the total number of non-compliant area lottery projects in the current sub-administrative region to the sum of the total number of non-compliant area lottery projects in each of the current sub-administrative regions.

[0166] Optionally, after obtaining the non-compliant area selected items, the method marks each of the non-compliant area selected items as non-compliant, and based on the non-compliant mark, extracts the non-compliant area selected items from the remaining surveying and mapping items, and places each of the non-compliant area selected items into the target supervision library; the remaining surveying and mapping projects are surveying and mapping projects other than the spot-checked items and the initial risk items.

[0167] Optionally, the implementation method of the non-compliance mark includes: adding a non-compliance code to the project name of the surveying and mapping project.

[0168] Step S123', based on the proportion of the number of selected projects in the non-compliant areas, detect whether the proportion of the number of selected projects in the non-compliant areas is greater than the preset risk proportion threshold, if not, then use each of the surveying and mapping projects in the current administrative area to be selected as the sampling project; if so, obtain the current secondary administrative area corresponding to the proportion of the number of selected projects in the non-compliant areas that is greater than the preset risk proportion threshold as the new current administrative area to be selected, and perform corresponding project sampling based on the administrative division level of the new current administrative area to be selected.

[0169] A surveying and mapping project risk identification method is provided in the above embodiment, which obtains sampling items from other surveying and mapping projects, performs compliance checks on each of the sampling items, and obtains risk items from each of the sampling items, thereby achieving comprehensiveness in the identification of the final risk items; and obtains sampling items based on the spatial distribution relationship between surveying and mapping projects and administrative regions at all levels, thereby reducing the randomness of obtaining the sampling items, and determines surveying and mapping projects within a certain administrative region as sampling items, performs compliance checks on the sampling items, thereby achieving accuracy in the identification of the risk items, so as to facilitate the rational allocation of regulatory resources and further improve the rationality of the allocation of regulatory resources.
