[0008] Step 3: Analyze the acquired abnormal utilization information, analyze the resource and environmental carrying value and the land space development adaptability value corresponding to the abnormal utilization land respectively, and calculate the comprehensive value of the abnormal utilization land by combining the two to obtain the comprehensive value information of the abnormal utilization land;

[0009] Step 4: Analyze the abnormal land use based on the comprehensive value information, compare the comprehensive value with the utilization index, and obtain the specific abnormal reasons by separately analyzing and screening the resource carrying value and the land space development adaptation value, and generate collaborative analysis information based on the specific abnormal reasons.

[0010] As a further solution of the present invention: the specific method of obtaining the land use information in step 1 is:

[0011] Determine the analysis area, obtain the corresponding regional planning land in the analysis area, and obtain the land information corresponding to the regional planning land, where the land information includes land area and land use. Then classify the regional planning land according to the land information. The specific classification processing method is as follows:

[0012] All planned lands are labeled as i, where i=1, 2, ..., j, where j represents the number of planned lands. Then, the land use situation corresponding to the planned lands is analyzed, and the planned lands with land use are classified as used land, which is denoted as a, where a=1, 2, ..., o. The planned lands without land use are classified as unused land, which is denoted as b, where b=1, 2, ..., p, where o and p represent the number of used land and unused land respectively, and o+p=j. At the same time, classification information is generated.

[0017] At the same time, the resource and environmental carrying values ​​of abnormal land use are monitored with time t as a period, and the resource and environmental carrying values ​​of multiple time periods t are obtained. At the same time, the resource and environmental carrying average values ​​of multiple time periods t are calculated, and then the resource and environmental carrying value information is generated based on the calculated resource and environmental carrying average value.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 3 , this application provides a land use collaborative evaluation method based on national land space planning, which specifically includes the following steps:

[0035] Step 1: Acquire the regional planned land and classify the planned land to obtain land use information, including used land and unused land. The specific method of generating land use information is as follows:

[0036] Determine the analysis area, obtain the corresponding regional planning land in the analysis area, and obtain the land information corresponding to the regional planning land, where the land information includes land area and land use. Then classify the regional planning land according to the land information. The specific classification processing method is as follows:

[0037] All planned lands are labeled as i, and i=1, 2, ..., j, where j represents the number of planned lands. The specific planned land refers to the scientific and reasonable classification and division of land in the overall plan and control detailed plan of the city (or town) to determine the use nature and function of different plots of land. Specifically, planned land involves various types such as residential land, land for public administration and public service facilities, land for commercial service facilities, industrial land, and logistics warehousing land. Each land type has its specific functions and requirements. Then, the land use situation corresponding to the planned land is analyzed, and the planned land with land use is classified as used land, denoted by a, and a=1, 2,…, o; the planned land without land use is classified as unused land, denoted by b, and b=1, 2,…, p, where o and p represent the number of used land and unused land, respectively, and o+p=j. Further, classification information is generated based on the classified planned land; specific used land refers to land that has been constructed or developed, such as residential areas, commercial areas, industrial areas, etc., and unused land refers to land that may be idle and has not yet undergone any form of development or construction.

[0038] Assume that there are 100 plots of planned land in a city plan (j=100). Through investigation and analysis, it is found that 70 plots have been used (o=70), including commercial areas, residential areas, etc.; the remaining 30 plots have not yet been developed (p=30). Each plot of land has a clear number, such as the 1st to the 70th plots are used land (a=1 to 70), and the 71st to the 100th plots are unused land (b=1 to 30).

[0039] Step 2: Analyze the classified utilized land, obtain the utilization index of the utilized land, and screen the utilized land according to the utilization index to obtain abnormally utilized land, and generate abnormal utilization information at the same time. The specific method of generating abnormal utilization information is as follows:

[0040] Acquire all the utilized land a, and at the same time acquire any piece of utilized land as the analysis object, and calculate the utilization index of the analysis object based on the ecological environment index and economic benefit index of the analysis object, and the calculation method here is to sum the ecological environment index and the economic benefit index, and so on to calculate the utilization index of all utilized lands, and then compare and analyze the utilization indexes of all utilized lands, and establish a corresponding relationship diagram, and at the same time, screen the utilized land according to the relationship diagram to obtain abnormally utilized land, specifically, when identifying and judging the relationship diagram, calculate the discrete value of the utilization index of all utilized lands, and use the calculated discrete value as the judgment standard, mark the utilization value greater than the discrete value as an abnormal index, and mark the corresponding utilized land as abnormally utilized land, and further generate abnormal utilization information. The calculation formula of the ecological environment index is: Ecological environment status index (EI) = 0.35 × biological abundance index + 0.25 × vegetation cover index + 0.15 × water network density index + 0.15 × (100-land stress index) + 0.10 × (100-pollution load index) + environmental restriction index, and the economic benefit index includes multiple aspects, including the comprehensive industrial economic benefit index and the economic benefit evaluation index. The corresponding economic benefit index is obtained by calculating the index and value of the two, and the calculation method is the existing technology, which will not be elaborated here.

[0041] The comprehensive index of industrial economic benefits is an important indicator reflecting the quality of industrial economic operation. Its calculation method is to compare the actual value of a certain economic benefit indicator (such as industrial product sales rate, industrial capital profit and tax rate, working capital turnover times, etc.) in the reporting period with the national standard value to obtain the dynamic index of each indicator. The actual value of each single economic benefit indicator in the reporting period is divided by the national standard value and multiplied by the respective weights, and then the sum is divided by the total weight to obtain the result. The formula is: Comprehensive index of industrial economic benefits = ∑ (value of a certain indicator in the reporting period ÷ national standard value of the indicator × weight of the indicator) ÷ total weight.

[0042] The economic benefit evaluation indicators specifically include the following:

[0043] Production and operation performance indicators: including return on assets, return on owners' equity, sales profit margin, sales revenue and its growth rate, etc.;

[0044] Consumption and consumption effect indicators: including sales profit margin, cost profit margin, unit product cost, unit product labor cost rate, etc.;

[0045] Indicators of capital occupation and occupation effect: including total asset turnover rate, fixed asset turnover rate, return on assets, inventory turnover rate, etc.

[0046] Step 3: Analyze the acquired abnormal utilization information, analyze the resource and environmental carrying value and the land space development adaptability value corresponding to the abnormal utilization of land respectively, and calculate the comprehensive value of the abnormal utilization of land by combining the two to obtain the comprehensive value information of the abnormal utilization of land. The specific method of generating the comprehensive value information of the abnormal utilization of land is:

[0047] The method of analyzing the resource and environmental carrying value of abnormally utilized land is as follows: basic information corresponding to abnormally utilized land is obtained, and the basic information includes the current land use status, topography, climate conditions, water resources, vegetation cover, soil type and quality, transportation and infrastructure conditions, etc. Based on the collected data, a comprehensive indicator system is constructed. This system should cover all necessary indicators required for resource and environmental carrying capacity evaluation, such as land quality, available water resources, ecological sensitivity, population density, intensity of economic activities, etc. According to the indicator system, appropriate evaluation models are applied to perform weighted calculations on each indicator. These models may include hierarchical analysis method, principal component analysis method, fuzzy comprehensive evaluation method, etc., to obtain the scores of each resource and environmental factor, comprehensively consider the scores of each indicator, and obtain the overall score or classification of resource and environmental carrying capacity through a specific algorithm (such as weight addition), and generate a resource and environmental carrying value;

[0048] At the same time, the resource and environmental carrying values ​​of abnormal land use are monitored with time t as a period, and the resource and environmental carrying values ​​of multiple time periods t are obtained. At the same time, the resource and environmental carrying average values ​​of multiple time periods t are calculated, and then the resource and environmental carrying value information is generated based on the calculated resource and environmental carrying average value.

[0049] The analysis method for the land space development adaptation value of abnormal land use is as follows: obtain the basic information corresponding to the abnormal land use, divide the construction and development suitability into four categories: most suitable, basically suitable, unsuitable and particularly unsuitable according to the suitability evaluation score results, use the zoning results and the current construction space area data to calculate indicators such as the limit development intensity and the current development intensity, obtain the matching degree of the current construction land layout, and calculate the deviation degree. At the same time, the calculated deviation degree is recorded as the land space development adaptation value. The details are as follows. Figure 2 and attached Figure 3 As shown, the adaptation value of national land space development corresponding to abnormal land use is calculated from multiple aspects.

[0050] The resource and environmental carrying value of abnormal land use is analyzed in the same way, and the mean value of land space development adaptation of abnormal land use is calculated in the same way, and the land development adaptation value information is generated.

[0051] The calculated resource and environmental carrying value of the abnormally utilized land and the land space development adaptability value are summed to obtain the comprehensive value corresponding to the abnormally utilized land, and the comprehensive value information is generated at the same time.

[0052] Step 4: Analyze the abnormal land use based on the comprehensive value information, compare the comprehensive value with the utilization index, analyze and screen the resource carrying value and the land space development adaptability value separately to obtain the specific abnormal reasons, and generate collaborative analysis information based on the specific abnormal reasons. The specific generation method is as follows:

[0053] The comprehensive value of abnormal land use is obtained, and the utilization index corresponding to the abnormal land use is obtained at the same time, and the two are compared. If the comprehensive value is the same as the utilization index, it means that there is no need to analyze the abnormal land use and a normal signal is generated. Otherwise, if the comprehensive value is different from the utilization index, it means that the abnormal land use needs to be analyzed and a secondary analysis signal is generated. The specific similarity and difference are expressed as the difference between the two is within the threshold range, and the specific value of the threshold range is set by the operator. Otherwise, if it is not within the threshold range, it means it is different.

[0054] Then, the generated secondary analysis signal is processed, and the resource carrying values ​​and land space development adaptability values ​​corresponding to the normal land use and abnormal land use are compared with each other, and the abnormal parameters are screened out. The mutual comparison here is to compare the resource carrying values ​​of the two with each other. At the same time, for the normal land use, the normal land use closest to the discrete value is selected as the standard for comparative analysis, and the abnormal parameters are analyzed at the same time. The specific analysis method is as follows:

[0055] The abnormal land use corresponding to the abnormal parameters is obtained, and the corresponding specific abnormal reasons are determined according to the abnormal parameters. Then the normal land use is obtained, and the normal land use is expressed as the corresponding utilization index is normal. The normal parameters corresponding to the normal land use and the abnormal parameters are obtained, and the normal parameters here indicate that the corresponding parameter properties are the same as the abnormal parameters. At the same time, the difference between the normal parameters and the abnormal parameters is calculated and recorded as the parameter difference, and the calculated parameter difference is used as the adjustment standard. Then the corresponding coordination method is determined according to the adjustment standard, and the coordination analysis information is generated.

[0056] Compare the parameters of normal land use with those of abnormal land use, and calculate the difference between the two, i.e. the parameter difference. This difference will be used as an adjustment standard for subsequent land management and restoration work. For example, if the vegetation coverage of normal land is 70% and the vegetation coverage of abnormal land is 30%, the parameter difference is 40%.

[0057] Specific coordination methods are formulated based on the parameter differences, which may include measures such as land fallow, vegetation restoration, and pollution control. At the same time, detailed coordination analysis information is generated, including implementation steps, expected results, and monitoring plans. In the above example, coordination methods may include prohibiting overgrazing and afforestation. The coordination analysis information will detail the implementation details of these measures and the expected vegetation coverage. After implementing the coordination method, regularly monitor changes in land use parameters such as vegetation coverage. Adjust land management strategies based on monitoring results to ensure that land use continues to improve and return to normal. For example, through annual monitoring, if it is found that the vegetation coverage has increased but is still below the target value, it may be necessary to increase the afforestation area or take other supplementary measures.

[0058] Some of the data in the above formulas are dimensionless and numerically calculated. Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0059] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
