Problems solved by technology
[0004] However, while the implementation of the balance policy of cultivated land occupation and compensation played a certain positive role, it also brought a series of problems, posing potential threats to regional food security, ecological environment, and social and economic stability.
The existing balance analysis of cultivated land occupation and compensation is mainly based on qualitative analysis or semi-quantitative analysis combined with relevant statistical data of cultivated land, which is easy to be involved in the interference of human subjective factors in the analysis process, which may seriously affect the corresponding analysis results

Embodiment
[0072] see figure 1 , figure 1 is a schematic flow chart of the quantitative analysis method for cultivated land occupation and compensation balance in the embodiment of the present invention.
[0073] Such as figure 1 As shown, a quantitative analysis method for the balance of cultivated land occupation and compensation, the quantitative analysis method includes:
[0074] S11: Determine the analysis area for quantitative analysis, collect analysis data in the analysis area, and obtain analysis data; the analysis data includes land use map data, cultivated land quality grade map data and ground elevation raster data;
[0075] In the specific implementation process of the present invention, in the embodiment of the present invention, a certain province is selected as the analysis area for specific quantitative analysis, and a certain province is used as the frontier area of reform and opening up. During 2011-2015, with the rapid growth of social economy and population, a ce...

The invention discloses a quantitative analysis method for cultivated land occupation-compensation balance, wherein, the quantitative analysis method comprises the following steps: determining an analysis area of quantitative analysis, collecting analysis data in the analysis area, and obtaining analysis data; the analysis data includes land use patch data, cultivated land quality grade patch dataand ground elevation grid data. After obtaining the analysis data, the quantitative analysis model is constructed and processed to obtain the quantitative analysis model. According to the analysis model, the quantitative and qualitative analysis, spatial heterogeneity analysis and landscape pattern analysis of cultivated land occupation and compensation are carried out in order to obtain quantitative analysis results. In the embodiment of the present invention, the quantitative analysis method oriented to the cultivated land occupation-compensation balance in the embodiment of the present invention can reduce the interference of artificial subjective factors in the analysis process, thereby obtaining more accurate spatial form and landscape pattern information of the cultivated land.
Description
technical field [0001] The invention relates to the technical field of cultivated land data analysis, in particular to a quantitative analysis method for the balance of cultivated land occupation and compensation. Background technique [0002] Land is the material basis for the survival and development of human beings. As the essence of land resources, cultivated land bears the heavy responsibility of ensuring food security and is closely related to the sustainable development of agriculture, social economy and ecological environment of the country and region. However, with the rapid development of the global economy and the continuous advancement of urbanization and industrialization, a large amount of cultivated land has been converted into non-agricultural land. [0003] Since China's rapid economic growth maintains a strong demand for arable land resources, and at the same time arable land resources are responsible for ensuring national food security, the Chinese governm...
