Multiple scale protection planning of waterbird habitats in Xi′an Chanba River wetland

Urban wetland and wildlife diversity protection is the important task of urban ecological construction.With the case study of Chan-ba River wetland in Xian City,the issues of urban waterbird habitat protection planning are discussed in this paper.By field investigation,the study area is found feeding 20 species,belonging to 8 orders and 12 families,showing a high birds diversity level.Some indigenous plant species and different habitat types are also found in the study area,with high value in sight of urban nature protection.The protection of the waterbird habitats in Chanba river wetland should be based on the relating theories of landscape ecology,conservation biology,and metapopulation,and carried on from different spatial scale.The main approaches include: habitat network construction,small habitat design,water depth control,and land use pattern optimization in riparian zone,plant community organization.
