基于 PSR 模型的干旱绿洲灌区耕地集约利用评价
Evaluation of a PSR model based intensive utilization of cultivated land in the arid oasis i rrigation area
摘要
Abstract
With the modern urbanization speeding up in recent years ,the contradiction between people and land has become more and more acute .As a result ,the limited land supply has restricted the development of social economy . Therefore ,using cultivated land intensively has become one of the core issues in the research field of land science .In this study ,Wuwei ,a city at the edge of the desert ,was selected as a representation to establish the evaluation system of intensive cultivated land use based on PSR model .The entropy value method ,comprehensive evaluation of range stan-dardization method ,and the method of multi factors were employed to evaluate the intensive use of land .The result indi-cated that in recent years , land composite index of Wuwei city increased rapidly from 0 .0805 in 2010 to 0 .1516 in 2012 ,similar to the coordination index .The result also showed that obvious regional diversities on the levels of intensive uses were observed in different cultivated lands .In 2012 ,the intensive use level of cultivated land in Liangzhou district presented the highest ,which reached 0 .5185 .Because Tianzhu county was still under unconstrained cultivation manage-ment ,the intensive use level in Liangzhou was as 3 .81 times as that in Tianzhu .In conclusion ,results from the evalua-tion using PSR model was consistent with the actual utilization of cultivated land in the target areas ,and the intensive uti-lization of cultivated land was low in Wuwei ,allowing potential improvement .关键词
