摘要
根据汾河上游五县(市)1998-2005年土地利用数据资料,分析了该区域土地利用变化特征.研究表明:1)在7年尺度上,林地、城镇村及工矿用地、交通运输用地面积增加,其余五类用地面积减少.林地面积变化最大、增加最快,园地数量变化最小,水域变化速度最慢.2)7年间,全区土地利用程度综合指数略有上升,但土地利用程度较低,土地利用程度变化存在区域差异.3)同类用地相比,牧草地、交通用地变化的区域差异在前4年间较明显,其余六类用地变化的区域差异则是在后3年间较明显.4)不同类用地相比较,前4年间城镇村及工矿用地变化的区域差异性最大,未利用土地变化的区域差异性最小,后3年间区域差异最大的是水域,最小的是交通用地.
Based on the data of land use from 1998 to 2005 in the upper reaches of Fenhe River, the characteristics of land use change in the district was analyzed. The results showed that 1） At the 7 years scale, the overall trend of land use in the district was an increase of forest land, settlement and mining land, and transportation land,and a decrease of other types of land. The area change of forestland was the most and the fastest. The area change of horticultural land was the least. The quantity change of water area was the slowest. 2） In the seven years,the integrated index of land use degree in the area increased. The land use degree in the area was low. There was spatial difference in land use degree change of the area. 3） The spatial variety of relative land use change degree of grassland and transportation land was more evident in the first four years than that in the latter three years, while that of other types of land in the latter three years was more evident than that in the first four years. 4） During the first four years,the most spatial variety of relative land use change degree was settlement and mining land, and the least spatial variety of relative land use change degree was unused land. During the latter three years, water area has the most spatial variety of relative land use change degree, and transportation land has the least spatial variety of relative land use change degree.
