摘　　要：利用景观生态学的方法分析了新乡市城市绿地系统的景观格局,结果表明:新乡市绿地斑块遭不同程度破坏,绿地景观呈破碎化趋势,景观多样性指数增加,绿地系统正朝着多样性和均匀化的方向发展,建成区绿地斑块缺乏完善的生态廊道,削弱了城市绿地系统景观生态功能的发挥.新乡市应大力加强城市绿地系统的景观规划、建设与管理,进一步完善新乡市城市绿地系统的结构,才能充分发挥其最大的景观生态效益.Based on the statistic data of Xinxiang city＇s green space system and landscape ecological methods, landscape patterns of urban green space system in Xinxiang city were studied. Three landscape ecological indices such as landscape diversity, landscape dominance, and landscape evenness were chosen to judge the landscape patterns of urban greening landscape. The results showed that there was fragmented trend in urban greening landscape, which was dominated by small patches with a great amounts and wide dispersion. Because of heavily deficient in integrated landscape ecological corridor, ecological service functions of urban green space system degraded greatly. In order to realize the optimal landscape ecological service functions of urban green space system in Xinxiang, therefore, we must make great efforts to conduct the landscape planning, construction and management of urban green space system, and the landscape pattern optimizing of urban green space system.
