摘 要:生态功能区划是生态系统和自然资源科学管理及持续利用的基础 ,可为生态恢复与重建提供科学依据。在综合分析石羊河流域生态环境基本特征的基础上 ,确定生态功能区划原则、依据、方法及命名 ,探讨利用 3S技术进行生态功能区划的方法 ,分析各功能区的主要特征。Ecological-function regionalization is the foundation of the rational management and sustainable utilization of ecosystems and nature resources, and it can provide the scientific basis for regenerating and conserving ecological environment. The Shiyang River Basin (37°07′~39°27′N,101°22′~104°04′E) is located in the east part of the Hexi Corridor, Gansu Province, its total area is 4.18×104 km2. In this paper, the part of the basin in Gansu Province is taken as the study area, and its area is 4.16×104 km2. In the basin, the highest peak, Mount Lenglongling (5 254 m a.s.l.), is perennially covered by snow, and the elevation of the lowest place, Baitinghai, is 1 020 m a.s.l. The precipitation is less in the basin, but the evaporation is high, and it is cold in winter but hot in summer. Based on analyzing the basic features of the ecological environment in the Shiyang River Basin, this paper discusses the principles, bases, methodology and nomenclature of ecological-function regionalization as well as the application of 3S technology in ecological-function regionalization. The basic futures of ecological-function regions are analyzed.
