利用廊道网络构建城市绿地生态系统——以东营市西城区为例

阐述了城市绿色廊道系统在城市绿地系统中的应用及生态价值，并在分析东营市西城区绿地系统现状的基础上，提出了建设西城区绿地廊道系统的方法，以加强城市孤立绿地斑块之间以及城市绿地与城郊外围自然环境的联系，优化城市绿地系统的结构，提高城市生态系统的稳定性.通过合理构建绿色廊道网络系统，西城区将新增绿地面积1400hm²，人均绿地面积将达到66m²，城市与郊区的绿地生态系统将贯通为一体，绿地生态系统的服务范围将扩展到整个城区，为提高西城区居民的生活质量，增强西城区生态敏感区的生态稳定性提供有力支持.

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 greenbehs and rural natural environment. Through the con- struction of this network, the greenbelt area in the west urban area of Dongying would increase 1 400 hm^2 , greenbelt area per capita would increase to 66 m^2 , and urban and rural greenbehs 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.
