[0035] Furthermore, the specific method for obtaining the results of the assessment of the current status of national land space planning is as follows: according to the importance and influence of each assessment indicator in the assessment indicator system of the current status of national land space planning in the assessment of the current status of national land space planning, analyze the assessment indicator weights; according to each assessment indicator in the assessment indicator system of the current status of national land space planning, analyze the assessment standards; according to the assessment indicator system, analyze the scores of each assessment indicator; according to the assessment indicator weights and assessment standards, perform weighted summation on the scores or values ​​of each assessment indicator to obtain the data of the assessment results of the current status of national land space planning.

[0036] In this embodiment, it is necessary to clarify the purpose of the assessment of the current status of national space planning and obtain the assessment objectives; according to the assessment objectives, a scientific and reasonable national space planning status assessment indicator system should be constructed; the indicator system should be guided by the concepts of safety, innovation, coordination, green, openness, and sharing, and set from the perspectives of quantity, quality, layout, structure, and efficiency. The indicator weights of each national space planning status assessment indicator in the assessment can be determined through expert consultation, statistical analysis, and other methods. The assessment criteria can be a specific numerical range, grade division, or descriptive language to measure the status quo of national space planning. Integrate the assessment objectives, indicator system, indicator weights, and assessment criteria into a detailed assessment guide to provide clear guidance for subsequent assessment work.

[0037] Furthermore, the specific method for analyzing the results of the current status assessment of national land space planning is as follows: obtaining the data on the current status assessment of national land space planning, and classifying and organizing the assessment result data according to the assessment index system; comparing the scores of different assessment indicators, analyzing the differences and connections between the assessment indicators, and obtaining a horizontal comparison of the assessment indicators; comparing the scores of the same assessment indicator at different times, different regions and different planning stages, analyzing the changing trends of the assessment indicators, and obtaining a vertical comparison of the assessment indicators; establishing a visual display platform for the current status assessment results of national land space planning, and storing the analysis data of the current status assessment results of national land space planning in the data storage module of the display platform.

[0038] In this embodiment, the data of the current status assessment result of the national land space planning is obtained, and the assessment result data is classified and sorted according to the assessment index system, which includes the scores, values, rankings and other information of various indicators. The highlights, problems and challenges in the current status assessment results of the national land space planning are identified; the indicators with higher scores in the current status assessment results of the national land space planning are the highlights in the current status assessment results of the national land space planning, and the indicators with higher scores often represent the excellent performance or remarkable results of the national land space planning in certain aspects; the indicators with lower scores in the current status assessment results of the national land space planning often represent the problems existing in the national land space planning, and the reasons for these low-scoring indicators are deeply analyzed; the challenges in the current status assessment results of the national land space planning are identified, and the future development trend of the national land space planning is predicted in combination with the current development trend and changes in the external environment. Using visualization tools, a visualized display platform for the current status assessment results of the national land space planning is established to present the current status assessment results of the national land space planning in an intuitive and easy-to-understand way. This helps to better understand and analyze the current status assessment results of the national land space planning.

[0039] Furthermore, the specific method for obtaining user feedback and evaluation data on the current status assessment results of national land space planning is as follows: displaying the current status assessment results of national land space planning to users through the current status assessment results display platform of national land space planning, and users complete feedback and evaluation on the current status assessment results of national land space planning through the display platform, and storing the user feedback and evaluation data in the data storage module of the display platform; obtaining the total cumulative viewing time of the assessment results through statistical analysis of user viewing records; obtaining the number of likes for the assessment results through statistical analysis of user likes records; and obtaining the total number of downloads of the assessment results through statistical analysis of user download records.

[0044]

[0045] like Figure 2 As shown in the figure, the feedback index of planning evaluation results changes with various factors, where β is set 1 =0.5,β 2 =0.3,β 3 =0.2. Figure 2 From Table 1, it can be seen that the planning evaluation result feedback index FK increases with the increase of the cumulative total viewing time LJ of the evaluation results and the number of likes DZ of the evaluation results, but the growth rate will gradually decrease. This shows that with the increase of the cumulative total viewing time of the evaluation results and the number of likes of the evaluation results, the improvement effect of the planning evaluation result feedback index will gradually weaken.

The planning evaluation result accuracy index JG can also obtain relevant data before and after the national land space planning, such as statistical analysis, questionnaires, expert opinions, etc., and use regression analysis, cluster analysis, etc. to quantitatively estimate the effect of national land space planning, and combine user feedback data to further analyze and obtain the planning evaluation result accuracy index. The higher the planning evaluation result accuracy index, the higher the accuracy of the national land space planning status evaluation results obtained by the current national land space planning status evaluation system.
