| 摘 要： | 流域尺度的生态功能区划能给流域生态环境保护提供更科学的理论依据。从北部湾南流江流域自身的地理特征出发，制定符合流域实情的区划原则，借助RS、GIS技术，采用定量和定性分析相结合的方法对流域进行生态功能区划。在空间上将南流江流域划分为6个一级生态功能区和18个二级生态功能区。6个一级生态功能区分别是：Ⅰ森林生态系统生态功能区、Ⅱ陆域水环境生态维护生态功能区、Ⅲ水土保持生态功能区、Ⅳ农林产品提供生态功能区、Ⅴ城镇发展生态功能区、Ⅵ滨海海域生态功能区。针对各个生态功能区存在的生态问题提出相应的生态系统管理措施。

| Abstract: | Watershed-scale ecological function zoning can provide scientific basis for ecological and environmental protection. This study is based on the analysis of watershed geographic elements, ecological sensitivity, ecosystem services, and extent of urban development and productivity layout. With RS, GIS technology, this paper uses combination methods of qualitative and quantitative analysis to make out the Nanliu River Basin ecological function zoning. Spatially the Nanliu River basin is divided into six ecological function zones: Ⅰ ecological function zone of forest ecosystems, Ⅱ ecological function zone of terrestrial ecosystem to maintain water environment, Ⅲ ecological function zone of soil and water conservation, Ⅳecological function zone of forestry products supply, Ⅴecological function zone of urban development, Ⅵ ecological function zone of coastal waters. The problems existing in the zones are expounded and the countermeasures against those problems are suggested in the paper. |
