城市自然保留地是快速城市化过程中保持生物多样性和复杂基因库的重要生境。在阐述城市自然保留地概念和内涵的基础上,讨论了城市自然保留地的特殊功能以及与传统园林绿地和自然保护区的区别。根据其特点和功能,从斑块特征、外部影响和干扰与斑块状况三方面构建城市自然保留地保护价值评估体系,包括斑块面积、斑块形状、连接度、植物群落和物种数量、当地人口密度、周围土地利用状况、隔离时间、干扰等十五个相关因子,并以天津市水上公园红莲岛为例进行实例研究。从重视城市生态基础调查与研究、重视自然保护的社区参与、正确评价城市的自然生境资源和加强管理等方面对城市自然保留地的保护提出建议。

Urban natural remnant site is an important habitat which can maintain biodiversity and complex gene bank.Based on the expatiation of definition and connotation of urban natural remnant site,this article discusses its special function and difference with traditional green space.According to the characteristics and functions of urban natural remnant sits,this article constructs the protection assessment system which includes 15 indicators,such as patch area,patch shape,connectivity,community,population density,and so on.This article takes Honglian natural habitat for example to give empirical evidence.Finally,some suggestions are put forward such as thinking highly of urban ecological background investigation and community public participation to natural protection,appraising urban natural habitat resource and improving management.
