| 摘 要： | 本文把石羊河流域看作一个完整的生态整体。从地形、地表组成物质、海拔高度、人类经济活动等方面探讨了土地的分异因素,同时按照综合性原则、主导因素原则、联系生产原则等划分了12个第一级土地类(相当于"土地系统"、"地方"),61个第二级土地型(相当于"土地单元"、"限区")。最后,就就第一级土地类的基本特征和利用方面进行了讨论。

| Abstract: | Shiyang River which is an easternmost inland river in China's deserts is situated in the Hexi region of G'ansu province. This paper discusses the Shiyang River Basin as a whole ecological unit, with special reference to the terrain differentiation factors as landforms, surface substance components, elevations and human activities. The whole-terrain in the basin is divided into 12 land classes (eq. to "lend system") and 61 land types (eq. to "land units"), taking the integrity of factors, leading factors, and land productivity as the main poin in the principle of classifica tion. At last, the principal characteristics and the directions of land utilization in different land classes are being discussed. This paper tries to make efforts in providing scientific data for the programming and management of the river basin. |
