苏州城市生态资源空间特征分析

Spatial characteristics of urban ecological resources in Suzhou

以园林和水城为特色的苏州市有着丰富的生态资源,但随着城市化的快速发展,城市生态资源变得越来越稀缺并且分布不均。运用遥感、GIS等空间信息技术,以主建成区植被、水体以及地表温度组合而成的生态资源指标,对苏州主建成区内的生态资源类型、分布进行评价分析。结果显示,苏州市生态资源以生态源、斑块、廊道、跳板、节点五种形式存在于基质之上,它们共同构成苏州市生态资源系统。针对建成区生态资源空间分布不平衡、生态网络不连续、部分小区植被覆盖度低等问题,提出了五种城市生态资源保护与建设措施。

Suzhou,characterized by gardens and water towns,has rich ecological resources.However,with the rapid development of urbanization,the ecological resources have become increasingly rare and unevenly distributed in space.Based on spatial information technology such as remote sensing and GIS,we investigated the types and distribution of ecological resources in the main built-up area of Suzhou.The results show that the ecological resources of Suzhou exist on the matrix in five forms:ecological source,patch,corridor,springboard and node.In view of the problems of unbalanced spatial distribution of ecological resources,discontinuous ecological network and low vegetation coverage in some residential areas,we put forward five measures for the protection and construction of urban ecological resources.
