| 摘 要： | 以甘肃省14个市(州)为研究单元,选取影响耕地利用效益的指标,采用多因素综合指数评价法和聚类分析法,从生态、经济和社会效益三方面对各市(州)耕地利用效益进行评价,分析耕地利用效益的时空分异特征。结果表明,1999～2008年,各市(州)耕地利用经济效益以嘉峪关市最好,白银市最差;耕地利用社会效益张掖市最好,甘南州最差;耕地利用生态效益平凉市最好,甘南州最差;耕地利用综合效益嘉峪关市最好,甘南州最差。从时间上耕地利用效益呈现出不稳定的波动状态。

| Abstract: | The cultivated land use benefits(economic,social and ecological benefits) of 14 prefctures and cities of Gansu from 1999 to 2008 were evaluated using the methods of multi-factor composite index appraisal law and cluster analysis.In terms of economic benefit,Jiayuguan city was the best while Baiyin city was the worst.For the social benefit,Zhangye city was the best while Gannan autonomous prefecture was the worst.In the aspect of ecological benefit,Pingliang City was the best;But Gannan autonomous prefecture was the worst.Considered together,the cultivated land use benefit of Jiayuguan City was the best while that of Gannan autonomous prefecture was the worst.These results showed that the utilization benefits of the cultivated lands had obvious regional differences.Besides,the utilization benefits of cultivated lands were unstable in the time domain. |
