中文摘要：
在界定耕地集约利用内涵的基础上,从耕地资源利用中的人地关系入手,构建基于PSR模型的耕地利用集约度评价指标体系,从区域空间的角度对四川省21个地级市州的耕地集约利用情况进行了测度和评价。研究结果表明：①成都平原地区耕地集约利用水平较高,川西高原地区较低,这主要是由于自然因素、经济发展和人地关系的差异所致;②PSR系统的协调度与耕地集约利用水平成高度正相关,充分说明PSR各子系统及其内部各因子之间的协调性很大程度上可以反映耕地集约利用的均衡度,模型可信度比较高。
英文摘要：
On the basis of defining the content for cultivated land intensive utilization,starting with the analysis of the man-land relationship in the course of cultivated land intensive utilization,the index system of cultivated land intensive utilization based on PSR model was established.Then the cultivated land intensive utilization of 21 cities in Sichuan province was calculated with the formation of the index system and the result was graded.Based on the facts of Sichuan province,two conclusions were drawn.First,cultivated land intensive utilization in the Chengdu plain area was more intensive than that in the Sichuan western plateau,because of the difference natural factors,economic development and man-land relationship of these areas.Second,cultivated land intensive utilization was positive correlate with the harmonious degree of PSR.This showed that the harmonious degree between every subsystem of PSR and other inner factors could reflect the balance degree of cultivated land intensive utilization,it also indicated the model was reasonable.
