摘  要：
闽江流域在福建省内生态地位非常重要,其核心区域特别是水源涵养地生态公益林的保护也显得尤为关键。本文基于水文分析、几何网络分析等数学方法与模型,科学有效地查找闽江流域的核心区:通过对福建地形进行水文分析模拟水系、流域的分布,应用几何网络分析构建河系空间网络模型并获取流域汇水区,结合福建省水功能区划成果获取闽江流域核心区范围,科学准确的定位闽江流域重点生态功能区。在此基础上借助地理信息系统空间分析等工具,通过与森林资源现状、土地利用现状等基础数据的空间叠加,分析生态公益林的空间布局、林地现状与保护现状,挖掘现有生态公益林保护存在的问题;探讨闽江源区面临的退耕还林等问题,为科学合理的进行生态公益林布局研究提供依据,进而优化生态公益林的空间配置。

摘  要：
Ecological status of Minjiang River basin is very important in Fujian Province. The core area,especially source's protection of ecological non-Commercial forest also is particularly critical. Based on hydrological analysis,geometric network analysis and other mathematical methods and models,this paper will scientifically and effectively search for the core area of the Minjiang River basin: with the hydrological analysis of Fujian topography,the distribution of water system and river basin is simulated,with geometric network analysis to construct a spatial network model and then obtain the catchment basin,combined with the results of Fujian water function regionalization,the core area of the Minjiang River basinwas obtained,scientifically and accurately locate the key ecological functional areas of the Minjiang River basin. On this basis,by means of spatial analysis tools of GIS for spatial overlay it uses the essential data such as land use statusand forest resources status,to analyze the ecological non-commercial forest spatial distribution,forest status and conservation status,to explore the problems of ecological non-commercial forest protection. It also discusses the problems of returning farmland to forest in Minjiang Source,so as to provide the basis for the scientific and reasonable study of the layout of ecological non-commercial forest,and then optimize the distribution of ecological non-commercial forest.
