摘要: 自然界中任何一片构成的功能单元都可以看作一个生态系统,如沙漠地区内陆河流域是个完整的功能单元,一个流域就成为一个近似于封闭的生态系统。生态系统的两个侧面——物理环境和生物——都是由复杂的变化着的系统构成,它们之间在一定地区的相互作用,有些作用则比其它作用表现得更为集中、更为强烈,干旱地区的水系统对人工绿洲来说就是如此。本文对石羊河流域生态系统的初步探讨,在生物系统中着重于生产者有机体——绿色植物,非生物系统——空气、水、土、太阳能(光、热)中侧重于水。本文把重点放在水系统与大农业生物系统的相互关系上,注意陷落在各有关基础学科缝隙间的问题。

Abstract: An interior drainage in the desert region is an integrated function unit.Such a basin is of an approximately closed ecosystem.This article is a preliminary result on the study of the Shiyang river valley,in which put emphasis on the relations between the water system and the agricultural ecosystem and pay attention to the marginal questions among basic subjects concerned. According to the questions revealed in the Shiyang river basin ecosystem the regulative methods were put forward.
