以干旱绿洲灌区这一特殊沙漠边缘地带武威市为例，构建基于PSR模型的耕地集约利用评价体系，运用熵值法、极差标准化法及多因素综合评价法来评价耕地集约利用。结果表明：近年武威市耕地综合指数上升明显，从2010年的0．0805上升到2012年的0．1516，并与协调度指数保持一致；不同的区县表现出不同的耕地集约利用水平差异，2012年凉州区耕地集约利用度最高，达到0．5185，天祝县耕地利用度呈粗放状态，前者是后者的3．81倍。利用PSR模型评价结果与研究区的耕地实际利用情况相符，武威市干旱绿洲灌区耕地集约利用水平低，提升潜力很大。
以榦旱綠洲灌區這一特殊沙漠邊緣地帶武威市為例，構建基于PSR模型的耕地集約利用評價體繫，運用熵值法、極差標準化法及多因素綜閤評價法來評價耕地集約利用。結果錶明：近年武威市耕地綜閤指數上升明顯，從2010年的0．0805上升到2012年的0．1516，併與協調度指數保持一緻；不同的區縣錶現齣不同的耕地集約利用水平差異，2012年涼州區耕地集約利用度最高，達到0．5185，天祝縣耕地利用度呈粗放狀態，前者是後者的3．81倍。利用PSR模型評價結果與研究區的耕地實際利用情況相符，武威市榦旱綠洲灌區耕地集約利用水平低，提升潛力很大。

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 .
