The current state assessment method for land space planning according to claim 1, wherein in S4, a data model is built, land space data is analyzed and assessed by comparing target data, the assessment is based on basic indexes of bottom line management, structural efficiency and life quality, six indexes are additionally arranged at the same time, an index system conforming to local reality is built, two indexes of land space development intensity and newly-increased ecological restoration area are respectively increased on the basis of the basic indexes of the country and serve as basic indexes, and for assessment index data, space analysis, difference comparison and trend research and assessment are adopted to conduct monitoring analysis, and each index data representation is combined to evaluate and judge six dimensional development levels.
7. The method for evaluating the current situation of the planning of the homeland space according to claim 1, wherein in the step S5, the data are visualized by using big data support, three-dimensional management of basic data is adopted, the basic data are real-time linked with monitoring data, the change of the basic data is instantly regulated in a three-dimensional environment, when the basic data are out of limit, the linkage early warning is carried out in the two-dimensional and three-dimensional environment, basic base map data, remote sensing images, DEM, three-dimensional fine models, oblique photography data, population, wind direction and planning project data required by the integration planning are displayed in real time, the integrated management, release and display of the two-dimensional and three-dimensional data are realized, a planning department can paint an uploading design scheme through a platform, provide parameterized design window, input planning parameters, automatically generate a three-dimensional model, automatically judge whether the planning scheme meets the requirement of a planning standard or not, and when the index is out of limit, the system gives warning in time, three-dimensional quantity calculation, profile analysis, visual field analysis, shadow analysis, sky line analysis, visual field analysis and slope analysis data required in the planning and design decision process are provided.
8. The current state assessment method for land space planning according to claim 1, wherein in S6, land space data is updated periodically, assessment results are adjusted, remote sensing technology is adopted, the method comprises a space information acquisition system, a ground receiving and preprocessing system, a ground live investigation system and an information analysis movement system, visible light, infrared and microwave detection instruments are utilized from various platforms in a long distance, high altitude and outer space, and the assessment results are adjusted in time based on updated information by photographing, information sensing, transmission and processing, displaying the land information data, transmitting the obtained data to an information base.
