基于生境网络理念的城市绿地系统规划研究——以浙江余姚市中心城区绿地系统规划为例

城市绿地为城市生物多样性保护提供了重要的空间保障，构建和优化城市绿地生境网络对保护城市生物多样性意义重大。根据生境网络的相关理论，阐述了生境网络在绿地系统中的定位和建设的必要性。以余姚市绿地系统规划为例，针对城市空间扩张中导致的景观破碎化、生物栖息地减少等问题，在城市绿地现状评价的基础上，从市域绿地系统规划、中心城区绿地系统规划等不同层次阐述了城市绿地生境网络系统构建的方法和策略，研究结果可为城市规划者进行城市绿地系统规划提供科学的依据与参考。

Urban Green Space System Planning Based on the Habitat Network Theory——A Case Study of Yuyao City in Zhejiang Province

Urban green space can contain rich flora that contribute significantly to biodiversity.The connectivity provided by habitat network in urban green spaces offers both habitats and corridors that improve conservation of biodiversity.The conception and theory of habitat network was presented,the necessity of the habitat network construction in greens system was elaborated.With the case study of Yuyao City in Zhejiang Province,the isolation of native habitats due to urban sprawl threatens biodiversity conservation was analyzed.Base on the assessment the current green situation,the plan of the urban green system and the city center green system based on different range was researched in the case,and the method and strategies about the habitat network were elaborated,but helped to identify the relative significance of each green space and guide urban planning.
