[Construction of urban green space ecosystem by using corridor network: a case study in west urban area of Dongying City, Shandong Province].

This paper discussed the ecological significance of urban green corridors network in urban green space ecosystem, analyzed the present status of green space ecosystem in the west urban area of Dongying in Shangdong Province, and figured out the ways of constructing urban green corridors network in this area to strengthen the linkage between its fragmented greenbelts, and between these greenbelts and rural natural environment. Through the construction of this network, the greenbelt area in the west urban area of Dongying would increase 1400 hm2, greenbelt area per capita would increase to 66 m2, and urban and rural greenbelts would be integrated into a whole system to serve the whole city, giving a powerful support to enhance the life quality of local people and the stability of urban ecosystem.
