The application relates to an ecological green core construction project access intelligent auditing method and system, relates to the field of text examination and approval, and comprises the following steps: extracting project red line vector data and construction content from a declaration data packet; superimposing and analyzing the red line data and a preset control factor layer set to obtain a space compliance detection conclusion and construct a space compliance characteristic parameter; selecting a rule subset from a hierarchical rule library according to a partition category and a superimposed area, assigning values to a judgment threshold according to a first difference value between a scale proportion of urban and rural construction land and a control upper limit and a second difference value between a scale proportion of residential land and the control upper limit, and obtaining a parameterized rule subset; comparing the construction content according to the parameterized rule subset, and outputting a list compliance conclusion; merging the space compliance detection conclusion and the list compliance conclusion to generate an access level conclusion, and triggering a corresponding examination and approval path and a compulsory examination and approval node. By implementing the method, the deviation between a list compliance auditing conclusion and the actual situation of land index control in a region where a project is located can be reduced.

This invention provides a fine-scale population spatialization method that integrates geospatial and internet data. The method includes: obtaining residential building footprint data within the study area; constructing geographic grid data for the study area and determining the proportion of residential building footprint area in each geographic grid unit; obtaining the number of floors in internet-connected buildings within the study area, establishing a residential building floor estimation model, and determining the initial input values ​​for the residential building floor estimation model; calculating the estimated population for each administrative region, performing error verification with the corresponding administrative region's population statistics, iterating based on the error verification results, and optimizing and adjusting the parameters of the residential building floor estimation model. This invention constructs a population spatialization model by integrating land use (residential land), surface-covered building areas, and the number of floors in internet-connected buildings, classifying the population living in urban and rural areas to estimate the floor height of residential buildings, achieving fine-scale population spatialization with high accuracy.

The present application belongs to the technical field of heavy metal contaminated soil environmental risk assessment, and particularly relates to an environmental risk assessment method for heavy metal contaminated soil remediation and building material recycling. The present application adopts simulated rainwater to leach the risk assessment system, calculates the diffusion coefficient of the remediated heavy metal in soil, and thereby constructs a one-dimensional heavy metal diffusion model. Then, according to the dilution and attenuation coefficient of the heavy metal in groundwater, the concentration level of the heavy metal in the building material released into the groundwater during the process of remediated soil recycling into building material is calculated. Finally, the potential drinking groundwater pollution risk possibly caused by the remediated soil recycling into the first type of land (residential land) is quantitatively evaluated. The present application has the advantages of simple method, clear process, short cycle, high efficiency, scientific rationality, and can accurately predict and evaluate the pollution risk of the local groundwater caused by the building material recycling of the remediated contaminated soil, which is beneficial to the protection of the groundwater environment, and the method provided by the present application has wide applicability.
