Abstract:

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.
