Jinan City Of Ecosystem Health Assessment Study

Urban ecosystem health assessment adapted to the urban sustainable development. Urban ecosystem health is human survival and development of the necessary conditions to maintain ecosystem health, and promote the benign cycle of ecological systems is related to the future and destiny of the human major issue.Maintenance of ecosystem health in Jinan City, Jinan Eco-city to the achievement of great significane. Construction of an urban ecosystem health evaluation system, and the Jinan City ecosystem health, a comprehensive assessment of ecosystem development Jinan study the situation, identify the health of urban ecosystems Jinan stress factors, optimization and management of the development of rational planning, promoting the construction of ecological city of Jinan, coordination between people and land to achieve economic and social sustainable development is of great significance. Based on the analysis of urban ecological composition, structure and function, based on the combination of the characteristics of urban ecosystems, according to urban ecology, ecological economics and other related theories, choose the 21 indicators, the establishment of Jinan City, ecosystem health assessment index system According to the principle of the coefficient of variation of the weights assigned each indicator. Home and abroad on the basis of urban ecosystem health level of the relevant standards, Jinan urban ecosystem health division of the five levels, according to membership function, calculated from 1995 to 2009 fifteen years of membership matrix, the use of fuzzy mathematics Methods of Jinan City, the status of urban ecosystem health evaluation on the time series. Analysis of urban ecosystem health in Jinan City, the reasons for change, puts forward corresponding countermeasures and suggestions to the development of the Jinan City to provide a reference for ideas.The main contents of this paper is as follows:The first part of the introduction.
