摘要

农业是西北干旱地区经济发展的重要组成部分

研究该区耕地资源变化对发展西北经济尤为重要。利用甘肃省近20a的土地变更数据

在遥感和GIS技术支持下

分析了甘肃省1988—2008年的耕地势态演变

并对引起耕地变化的主要因子进行了灰色关联分析。分析结果表明

经济发展水平、二三产业及农业结构调整这几种因子与耕地变化的关联度分别高达0.898

0.892和0.883;其关联度排序也位居前三

成为推动甘肃省耕地资源变化的主要因素。最后对各影响因素进行了深入分析

并提出了甘肃省耕地资源可持续利用的意见与建议。

Abstract

Agriculture is an important part of the economic development in the northwest arid area. Research on the cultivated land change is particularly important to the development of the economy in Northwest. Based on the data from landuse change survey and socio-economic statistic data in Gansu Province in nearly two decades

the situational development of cultivated land resource and spatial patterns were analyzed under the support of GIS and remote sensing and the grey correlation analysis was made to find the main factors to cultivated land change. Results showed that the correlations of the change in cultivated land and the factors of economic development level

two tertiary industries

and agricultural structure adjustment were as high as 0.898

0.892

and 0.883

respectively. Finally

each impact factor was deeply analyzed and some comments and suggestions were given for sustainable utilization of cultivated land resource in Gansu Province.
