[0003] In the process of planning land space, planners are required to evaluate the carrying capacity of resources and environment and the suitability of land space development. The evaluation process of carrying capacity of resources and environment and the suitability of land space development is cumbersome, and the evaluation accuracy is low. The efficiency is low, and the results of the evaluation are difficult to quantify

Embodiment 1
[0051] Such as figure 1 As shown, the application provides a GIS-based land space planning optimization method, the method includes the following steps:
[0052] Step S1, selecting the region to be optimized from the GIS system.
[0053] Step S2, obtaining the real map of the spatial distribution of the land in the area to be optimized, and obtaining the basic data in the area to be optimized according to the real map of the spatial distribution of the land.
[0054]Specifically, the real map of the spatial distribution of the land in the area to be optimized is obtained from the GIS system, and the real map of the spatial distribution of the land is displayed on the screen of the GIS system in the form of a three-dimensional image. The real map of the spatial distribution of the land includes buildings, roads, rivers, etc. , agricultural areas and green belt areas.
[0055] Among them, the basic data include: agricultural plots, industrial plots, urban construction plots, w...

Abstract
The invention provides a GIS-based territorial space planning optimization method and system. The method comprises the steps of selecting a to-be-optimized region from a GIS system; acquiring a territorial spatial distribution realistic picture in the to-be-optimized area, and acquiring basic data in the to-be-optimized area according to the territorial spatial distribution realistic picture; evaluating the to-be-optimized area according to the basic data to obtain an evaluation result; optimizing the territorial space according to the evaluation result, the basic data and a preset optimization index; and obtaining an optimized territorial space planning map. According to the method, the existing territorial space planning situation is optimized according to the live-action picture in theGIS and different optimization indexes, automatic, high-efficiency and high-accuracy territorial space planning optimization operation is realized, and manpower and cost are saved.
Description
technical field [0001] This application relates to the technical field of image processing, in particular to a GIS-based land space planning optimization method and system. Background technique [0002] At present, land and space resources play an important role in the development of society and economy. With the development of urbanization, industrialization and agricultural modernization in our country, problems such as environmental deterioration, resource shortage, disordered space development and unbalanced regional development have emerged, which are becoming more and more serious. Land space planning is based on a deep understanding of the current state of land space, mainly including resource and environment carrying capacity, existing development intensity, and development potential, and plans the future of land space from the perspectives of development, renovation, and protection. The scientific and reasonable planning for the development of a certain period of t...
