Geographic national condition perspective-based land resource bearing capacity comprehensive analysis method

Abstract

The invention belongs to the field of an earth space information system, but not limited to the field of territorial space planning, natural resource special investigation and monitoring, territorial development and utilization, resource intensive utilization, basic public service supply and the like, and discloses a geographic national condition perspective-based land resource bearing capacity comprehensive analysis method. The method specifically comprises the following steps: S100, carrying out data collection, analysis and arrangement; s200, carrying out data preprocessing and integration; s300, matching and determining the analysis unit; s400, constructing an index system; s500, carrying out index calculation; and S600, carrying out comprehensive statistical analysis. According to the method, regional land resource bearing capacity and spatio-temporal change characteristics can be analyzed and revealed from the perspective of geographic national conditions, scientific and detailed information can be comprehensively obtained, geographic national condition monitoring data can be converted into geographic national condition information, and improvement of the geographic national condition monitoring data into geographic national condition information is facilitated; effective fusion of social and economic thematic information and geographic information is accelerated, and application and sharing of geographic national condition monitoring results are promoted.

Description

technical field [0001] The invention belongs to the field of geospatial information systems, but is not limited thereto. It can be used in the fields of land space planning, special investigation and monitoring of natural resources, land development and utilization, intensive use of resources, and supply of basic public services. Comprehensive analysis method of land resource carrying capacity from the perspective of national conditions. Background technique [0002] While our country has achieved rapid economic growth, coupled with the surge of immigrant population, the consumption of natural resources has continued to increase, and the phenomenon of waste and destruction of resources is common, which has exacerbated the contradiction between resource supply and demand, especially land resources as the foundation support. The contradiction between supply and demand is more acute. After decades of development, by analyzing the current research status at home and abroad, the...

Problems solved by technology

[0005] (2) Quantification and measurement methods are not uniform

[0006] At present, there are many studies on the carrying capacity of land resources, and there are also many discussions on the objects carried by the carrying capacity of land resources and the methods of application. However, the academic community has not yet reached a consensus on these methods, which has caused inconsistencies in the measurement standards and data in practical applications. Inconsistencies in source time and non-standard measurement methods make it impossible to compare the results obtained by different methods and models, which greatly hinders the establishment of an evaluation system for the carrying capacity of land resources

[0007] (3) Lack of spatial analysis, the research is too simplistic

[0008] Most of them are limited to the biological yield of land resources, which are very one-sided and limited. They have not made good use of modern remote sensing, geographic information system, geographic national conditions monitoring and other related technical means. The application of new technologies and new means is relatively lagging behind and lacks spatial analysis. content, especially the lack of research that combines the above technical means with spatial analysis
