本文基于P-S-R模型法建立耕地利用集约度评价的指标体系,利用主成分分析法得出各指标权重,进而计算各市州耕地利用集约度得分值。利用ARCGIS10.0建立四川省耕地利用集约度分区。最后,通过对四川省耕地质量和集约利用度进行回归分析,得到四川省耕地质量和耕地利用集约度的线性回归方程。
Based on the P-S-R model method, this paper establishes an index system for evaluating the degree of intensive use of cultivated land, and uses the principal component analysis method to obtain the weight of each index, and then calculates the score of cultivated land use intensity in each city. Using ARCGIS10.0 to Establish Intensive Cultivated Land Use Division in. Finally, by regression analysis of the quality and intensive utilization of cultivated land in Sichuan Province, a linear regression equation of cultivated land quality and intensive use of cultivated land in Sichuan Province is obtained.
