湟水流域典型县域土地可持续利用分区研究

An Analysis on Regional Division of Land Use in the Typical Area of Huangshui River Basin by GIS

运用GIS技术和数学模型方法,以湟水流域典型县域互助县为例,在分析研究区土地利用现状分析的基础上,重点分析了县域土地利用分区。结果表明:将研究区土地可持续利用分区划分为川水河谷粮、经、林高产稳产区、浅山中山水土保持农林区、半浅半脑丘陵农业稳产区、脑山中山农牧复合区、北部高山林牧发展区和中部盆地工业城镇建设区6个不同分区,并有针对性地提出了各区域的土地可持续利用方向。结合分区图和该县的具体情况,分区结果还是比较合理和切合实际的,可以为该县乃至整个湟水流域土地利用分区提供思路,对于湟水流域社会经济、生态的发展具有积极的意义。

Take the case of Huzhu County; a transition zone from the Qinghai-Tibet Plateau to the Loess Plateau, this paper makes a study on the land use change by GIS and mathematical model. At first analyze the status quo of land use, focusing on analysis of the land use status quo, land use pattern, land use zoning. The class 1 of land use model in each Town of Huzhu County is woodland, grassland, cultivated land and unused lang. And the tendency of the land use types transforms from the northeast to southwest, that is, from woodland to grassland to cultivated land. study area land use zoning is divided into 6 different partition, and pertinently put forward the regional land utilization direction and control measures. Combined with area chart and the specific circumstances of Huzhu county, partition result is reasonable and practical, can be in Huzhu regional land use zoning provides ideas, come to the study＇s positive significance to socioeconomic development and eeo-development of Huzhu County.
