Abstract
Accurate and scientific assessment of cultivated land quality is of great significance for controlling the production efficiency of cultivated land and finely managing cultivated land resources. Taking Luyi County as an example, this paper uses 20164 arable map spots as the grading unit, combining quantitative and qualitative analysis, GIS model spatial analysis and difference comparison, etc., through the natural, social, economic, etc. that constitute the quality of cultivated land. Comprehensive comparison of factors, establish a grading evaluation system for cultivated land, determine the factor factor system and influence weights, and explore the method of dividing the quality level of cultivated land. The research shows that: (1) the cultivated land level has a significant positive correlation with the cultivated land, and both can better display the grain yield or total production level; (2) the level ratio can better reflect the cultivated land use. Level, which indicates that the grain output changes more broadly and is easier to quantify the difference in grain yield, so it is easier to achieve land remediation performance evaluation in the province; (3) the quality level of cultivated land has a certain correlation with the location level and utilization efficiency. And the level is better than the other to reflect the spatial distribution of cultivated land. Provide data support for the value accounting of cultivated land resources in the region and the relationship between cultivated land occupation and subsidies.
