石羊河流域水土资源的供需状况成为决定该地区发展的生命线。随着地区社会经济的发展,土地利用的格局、深度和强度在不断变化,土地利用的类型也趋于多样化。利用石羊河流域1980年、1990年、2010年三期土地现状数据分析该流域各县市的土地利用类型的变化,比较1980--1990年、1990--2010年两个时段土地利用转换,引入上升性理论与方法分析两个时段土地利用类型转移的整体效果。从分析结果来看,随着土地利用类型的转移,整体上提高了石羊河流域土地资源利用的效益与效率,提升了流域土地利用的发展潜力空间。
The status of supply and demand of water and soil resources became the lifeline of regional development decision. With the development of social economy, the pattern of land use, the depth and intensity changed constantly, various types of land use tended to. In this paper, the Shiyang River Basin in 1980,1990,2010 three land status data analysis of change of land use types of cities and counties in the Shiyang River Basin, comparison of 1980 - 1990,1990 - 2010 in two periods of land use conversion, the overall effect of the rise of theory and method for the analysis of the two periods of land use types transfered. From the analysis results, with the land use type of transferring, and improving the overall efficiency and the utilization efficiency of land resources of fiver basins, enhanced the development potential of space using watershed land.
