淮北市城市绿地景观空间结构分析

Analysis of spatial structure of green space landscape in Huaibei

以《淮北市城市总体规划(2006-2020年)》为主要基础资料,通过实地勘察,得出现有绿地斑块面积与周长等信息,选择了5个主要景观评价指数对淮北市城市绿地景观空间格局进行分析评价.结果表明:淮北城市绿地景观总体表现为绿地斑块分布不均衡,景观结构不合理,破碎度较高,景观类型较齐全,均匀度较低,景观分离度较大.淮北市城市绿地景观存在着景观结构不合理、破碎度较大、景观类型分布不均匀等问题,针对存在的问题,提出了对淮北城市绿地景观结构应进行合理布局、增加各类绿地类型面积分布的均匀度、合理利用煤炭开采荒废区与城市外围生态防护林进行大中型绿地斑块建设等生态规划建议.

Taking the ＂urban overall planning of Huaibei city（2006-2020）＂ as main basic material,combining on- the-spot investigation,amusing five main landscape evaluation index,the urban green space landscape pattern were analyzed and evaluated in Huaibei.Overall distribution of green patch was disproportion and the structure of greenland system wasn＇t reasonable.Separation index was high,the landscape types were rather complete,the evenness degree was low and separation index was large.The green landscape of Hnaibei exist some problems of unreasonable landscape structure,a larger degree of fragmentation,uneven distribution of landscape types.In view of the existing problems,this paper puts forward the reasonable layout of urban green space in Huaibei city,increase of all kinds of greenbelt area distribution uniformity,rational use of coal mining waste area and urban peripheral ecological protective forest of large and medium-sized green space construction of ecological planning advice.
