摘要: |
该文以山西省忻州市14个县(市、区)域为评价单元,采用层次分析法构建农用地集约利用评 价指标体系,定量计算2000~2009年农用地集约利用水平,并采用GIS手段进行农用地集约利用水平的空 间差异分析。结果表明:现阶段的农用地集约利用水平主要依赖于对土地的高投入和高产出,可持续利用 状况对土地集约度的贡献较小;从时间上看,忻州市整体上农用地集约利用向着更集约利用的方向发展; 从空间上讲,忻州市14个县(市)农用地集约利用水平差距较大,且不同地区影响土地集约利用的因素 有所不同。 |

Abstract: |
Taking the 14 countries of Xinzhou City in Shanxi Province as evaluation units, this paper established e- valuation index system of the agricultural land intensive utilization using analytic hierarchy process, calculated the level of agricultural land intensive utilization from 2000 to 2009 and analyzed the spatial difference using GIS tech- nology. The result showed that the level mainly depended on high input and output into land, and sustainable utili- zation had little contribution to the degree of land intensity. In terms of temporal scale, the agricultural land inten- sive utilization becomes better and better in Xinzhou City, while the spatial scale it had big differences among the 14 counties, and the impacting factors were different in different areas. |
