The Research On The Landscape Health Assessment Index System Of Urban Wetland Park

Being the richest biodiversity and ecological landscape in nature and one of the most important human living environment, Wetlands have a powerful ecological functions and benefits. Urban wetland is an important natural resources of the country ,an important part of urban green space system ,which plays an important role in urban biodiversity conservation, urban landscape construction as well as ecological and environmental construction.

The establishment of urban wetland park has become one of the important ways to protect and use urban wetlands effectively.Since the urban wetland park construstion and research of China are still at the initial state, the establishment of a scientific and reasonable assessment index system is helpful to guide the development of urban wetland park into a profitably way and put the urban wetland park construstion into the overall framework of urban ecological environment construction. Landscape scale ecosystem health research could provide a basis for integrating natural ecological processes and social economic values.Based on the theory of landscape health, landscape ecology theory, establishment of a system of indicators of the need for and feasibility analysis basis, put landscape health assessment evaluation system is divided into four parts ~ landscape change indicators, bio-physical indicators, eco-environmental indicators and social-economic indicators, associative with urban wetland park features, extraction urban wetland landscape health assessment indicator elements,established the criteria and weightiness for assessment indicators. Construct landscape health assessment index system of urban wetland park. Finally, the choice of Hangzhou Xixi National Wetland Park as an example for a comprehensive evaluation process demonstration.
