Study on Wetland Health Assessment and Adaptive Management of Shaanxi Hanzhong Crested Ibis National Nature Reserve
摘要
Abstract
To investigate the health status and influencing factors of the wetland ecosystem in the Shaanxi Hanzhong Crested Ibis National Nature Reserve,a health assessment index system for the wetland ecosystem was constructed based on the PSR(Pressure-State-Response)model and the Analytic Hierarchy Process.The results show that the wetland ecosystem health grade of the reserve in Shaanxi Province is very healthy.The natural environmental factors with important influence on the wetland system are wetland water quality,net primary productivity of vegetation,and landscape diversity;the human activity factors with significant impact are sewage treatment rate,population education level,and environmental investment index.The main pressure on the wetlands in the reserve are land use and excessive regional hemical fertilizers application.In the future,it's necessary to strictly control changes in land use types within the reserve,improve the wetland ecological compensation mechanism,and control the total amount of chemical fertilizer to ensure the health and sustainability of the wetland ecosystem in the reserve.关键词
