黄土高原小流域土地类型分类及制图研究--以固原市上黄试区为例

Classification and Mapping of Land Type in Small Watershed in Loess Plateau——Take Shanghuang Test Area in Guyuan as an Example

文章以固原市上黄试区为研究对象,在综合性、主导性和实用性分类原则的指导下,建立了黄土高原小流域尺度上的土地类型分类体系,并借助Arcview/Arcinfo/Erdas等地理信息系统软件对分类结果进行了制图。以期为今后相同地貌类型和尺度下的土地类型分类研究奠定工作基础,同时为上黄试区水土流失治理与土地资源的合理配置提供科学依据。

In this paper, we established a classification system of land type in a small watershed in Loess Plateau, and draw the land type map by using Arcview/Arcinfo/Erdas. In order to provide some foundation jobs for the future study of land type classification in the similar regions and scales, and offer scientific evidence for avoiding water and soil loss and the reasonable use of land resource.
