QUANTITATIVE ASSESSMENT OF ECO-CITY CONSTRUCTION IN THE YANGTZE DELTA

The Yangtze Delta is a full-fledged metropolis in China.With the construction of eco-city springing up increasingly,cities in the Yangtze Delta also began their eco-city building one after the other, and have acquired important advances in the construction of eco-city.However,there are also some questions such as the non-harmonious development of city social-economic-environmental system and the difficulty to quantify the extent of eco-city construction.Based on the actual circumstance and the actual degree of the social and economic development of the Yangtze Delta,a local-character eco-city index system was set up——including city ecological index,city harmony index and eco-city comprehensive index——to evaluate the ecological level,the coordination level and the eco-city construction level of cities in the Yangtze Delta.The results indicated that:(1) as for the construction of eco-city,Suzhou is the best among the 15 cities in the Yangtze Delta,while Nantong the worst;(2) the sustainable development of eco-city is based on the all-round development of the city.
