GAP Analysis of Wetland Bird Habitat Diversity in Sanjiang Plain

摘要

Sanjiang Plain was chosen as the study area in this paper,based on the relationship between species and their habitats,using principles of landscape ecology and protection biology,"3S" technique,GAP analysis of biodiversity protection on a regional scale,same surface areas of hexagons as forecasting and evaluating units to analyze protection status of wetlands birds and diversity of their habitats,to find the unprotected biodiversity hotspots there and then analyze the priority protection.As expressed from the research,some birds under second class state protection as Bubo bubo,Falco peregrinus，Accipiter gentilis，Falco tinnunculu ，and Strix uralensis have not been well protected,ecological systems of forest hummocks,reed swamps and river wetlands gets worse protection.Thirteen hotspots have been discovered in this area,which are mainly distributed in surroundings near nature reserve and coast of some great rivers.GAP analysis for regions lacking data proposed in this paper not only put forward scientific evidence for the protection and management of wetland biodiversity in Sanjiang Plain,but also enriched theories and methods for China biodiversity protection.
