| 摘 要： | 干旱区内陆河流域生态系统组成要素和影响因素的区域差异性决定了不同区域具有不同的生态功能.地处甘肃河西走廊东段的石羊河流域生态环境的恶化正是流域生态功能紊乱的表现.本文分析了石羊河流域生态环境存在的问题及成因,并尝试对流域作两级功能区划分,讨论了不同生态功能区的作用及其调控对策.流域生态功能区划是流域综合管理的基础,有利于流域生态系统的稳定,有利于区域资源优势的发挥. |
| 关 键 词： | 石羊河流域 生态功能区划 流域综合管理 |

| Abstract: | In dryland, the regional difference of a basin ecosystem's components and their influence factors decide the different regions which have different eco-functions in a watershed system. The degradation of eco-environment in Shiyang River is just the turbulence of eco-function. Based on the analysis of the eco-environmental degradation and the reasons thereof in Shiyang River Basin, this paper tries to regionalize the basin according to the eco-function in different scale and puts forwards the function and adjustment strategies in respective regions. Aided by GIS, four eco-functional regions and ten subregions were distinguished, and basic features for each subregion were described. The eco-functional regionalization in inland rivers, which provides a sound background for integrated basin management, will benefit ecosystem balances and promote rational utilization of natural resources. |
| Keywords: | Shiyang River Basin eco-functional regionalization integrated basin management |
