Assessment method of ecosystem health

Abstract

Abstract: Ecosystem is the basic unit to maintain human environment. Ecosystem function mainly includes two aspects:e-cosystem service function and goods function. These two functions are the basis for human living and development. Ecosystem health is the presupposition of ecosystem function. The completeness (structure and function), resilience, stabilty, and sustainability are the characteristics of ecosystem health. Ecosystem health assessment selects the indicator based on the ecosystem structure and function, including completeness, suitability, and effectiveness of ecosystem. Ecosystem health assessment mainly has two methods :one is indicator species assessment, and the other is structure and function index assessment which includes single index assessment, complex index assessment, and index system assessment which includes natural index system assessment and social-economic-natural index system assessment. In this paper, different assessment methods on ecosystem health are compared, and different health assessment method for different ecosystem types are also expatiated.
