基于景观生态学的城市绿地系统规划布局评价——以包头市城区为例

该文以包头市城区绿地系统为研究对象,利用景观生态学的斑块—廊道—基质理论、景观异质性理论及生物多样性理论对包头市城区绿地系统规划布局进行分析评价。结果表明:包头市城区绿地景观网络不完善,城区内外绿地景观生态格局缺乏足够的连接,城区内的绿地斑块分布不均,新、旧城绿地建设差距较大,同时城区绿地景观特色不明显,绿地景观异质性不高,绿地景观类型单调。因此在今后的城市绿地规划中应注重加强城市绿地景观的连续性,合理安排城区绿地斑块,发展不同功能的特色绿地景观,使包头市城区绿地系统形成"城在林中,绿在城中"的城市生态网络。

THE APPRAISAL OF URBAN GREEN SPACE SYSYTEM PLANNING BASED ON THE PRINCIPLES OF LANDSCAPE ECOLOGY——A CASE STUDY OF BAOTOU CITY

In this paper,taking the urban green space system planning of Baotou city as the research object,the urban green space system layout of center area in Baotou has been analyzed by applying the landscape ecology patch-corridor-matrix theory and the landscape heterogeneity and the biodiversity theory.The result indicated that,the urban green landscape network is imperfect,the city inside and outside green landscape ecology pattern lacks the enough connection,the urban green patch distributed non-uniformity,the new city and the old city green constructs the disparity in a big way,the city landscape characteristic is not obvious,the landscape type monotonous.In the future,the urban green space system planning should pay great attention to strengthen the continuity at the city green landscape,arrange the city green patch reasonably,and development different function characteristic green landscape,make the urban ecological network in the form of "city in forest,green in city" in Baotou.
