The ecological environment issues caused by urbanization seriously block the development of cities.Therefore,the building of ecological cities becomes the most important measure of sustainable development.This paper adopts PSR model as the framework of the eco-city construction indicator system,and builds the eco-city construction indicator system aiming at the characteristics of the coastal eco-city construction which bases on the indexes of national eco-city construction,and applies entire-array-polygon method to make the trend analysis of synthesis development ability of Yantai eco-city.The research results indicate that the complex ability for sustainable development in Yantai city went from moderate to better between 2005 and 2010;the complex ability of sustainable development of Yantai city is predicated to increase from 2010 and 2020 according to "The constructive planning of Yantai ecological city".So this paper proposes targeted management measures.It provides an evaluation indicator system and management strategies for the eco-city construction of Yantai city and tries to perfect the indicator system for the eco-city construction of coastal cities.
