Embodiment

[0093] The intensive use of cultivated land is related to the natural and socio-economic attributes of cultivated land, such as geographical location, topography, climate, water resources, soil, farming system, crops, etc. Therefore, the use of cultivated land has obvious regional differences. Therefore, the standards for intensive use of cultivated land are also different in different regions. According to the "Agricultural Land Grading and Grading Regulations" issued by the Ministry of Land and Resources, in Appendix B "National Cultivation System Division", a province is divided into two national first-level districts (Huanghuaihai District, Inner Mongolia Plateau and the Great Wall area, four National second-level district. According to the regulations, a certain province has a 1:1 million topographic map of a certain province, a certain provincial agricultural division, a certain province's planting division, a certain province's soil division, soil improvement division, a...

Abstract

The invention belongs to the environment field of agricultural resources, and is an evaluation method for intensivism use of land, comprising, proposing that the intensivism use includes 4 parts of input intensity, utilization degree, output effect and social benefit of land, establishing a evaluation index system and an index determination method of intensivism use of land and proposing the evaluation index and a determination method thereof for intensivism use potential of land. The invention determines a relatively scientific and rational evaluation indicator system by 3-grade screening procedure of frequency analysis, Delphi and multivariate statistics for a lot of primary evaluation indexes and the weight of each index by using the combined method of principal component analysis and hierarchical analysis. The invention improves the single index screening and weight determination to analyze the dynamic change of intensivism use for land and determine the potential at a certain time point, and is a rare quantitative evaluation method for the field of evaluation for regional agricultural resources or quantitative calculation for intensivism use potential of land.

Description

Technical field: [0001] The invention belongs to the field of agricultural resources and environment, in particular to an evaluation method for intensive utilization of cultivated land. Specifically, it is a method to evaluate the input intensity, utilization intensity, output effect, social benefit and utilization potential of cultivated land. Background technique: [0002] With the increase of population and the reduction of cultivated land, the contradiction between more people and less land has become increasingly prominent. The shortage of land resources has long been a constraint factor for my country's social and economic development. The relationship between man and land will become more tense, and the problem of food security will also become more severe. Improving the output per unit area of ​​cultivated land, changing the pattern of extensive land use, and striving to realize intensive use of cultivated land are the keys to solving the important contradiction betw...
