摘要
分析研究了内陆河流域气候条件，植被生态，土壤环境及水环境质量等生态环境要素的空间变异特征，探讨了流域不同地带的生态环境功能。结果表明：干旱内陆河流域气候条件，尤其是水热条件和地貌特征是植被生态，土壤环境及水环境形成与分异最主要的控制性因素，几大环境要素之间相互联系，相互制约形成内陆流域生态环境空间分带规律和生态系统功能在空间不同地带上的显著差异性，认识这种分带规律与不同区域的生态功能，是合理开发内陆河水土资源的基础。
The spatial differential features of climate conditions, vegetation ecology, soil environment and water envionmnet are analysed in this paper. The ecological functions in different regions are discussed. The results show that, in arid inland river basins the climate conditions and geomorphologic features are the main factors that govern the formation and variance of soil and water environments and vegetation ecology. The main environmental factors which are related with and depended on each other, have formed the spatial distribution laws of eco environment and the spatial variance of ecological functions in inland rvier basins. Recognizing these laws and functions of elo environment in different regions was the foundation of rational utilization of the water and land resources.
