Green work is the production of green space that people desire to improve the ecolo gical environment of the city and built the green work. Chin a's big cities most serious environmental pollution, poor quality, has e the impact of urban life quality primary factors. Therefore, the ecological function of the wor k with control and gove rnance embodied must combine environmental pollution, and exert the fight corrupt, reduce heat, protective, and other functions. In respect of natural environment and ur ban planning design method, by which establish ecological environment func tion prominent work, to improve the urban biodiversity, strengthen urban natural at tributes are also our country can't wait to resolve problems. At present our country to improve the greenway network the ecological environment function of research and practice also is in preliminary exploration stage, therefore, it is urgent to summarize the green work and the ecological environment, relevant link between for c onstru
