城市湿地公园景观健康空间差异研究——以杭州西溪湿地公园为例

景观健康研究是生态系统健康的新研究方向，两者区别在于研究尺度的选择。景观健康的标准体现在景观能否可持续发展。作为城市湿地的西溪湿地公园，其可持续性表现在社会经济和生态保护的和谐发展。因此，本文从社会经济和生态保护两方面建立景观健康评价模型，运用GIS 技术使其空间化，揭示景观健康的空间差异性。结果显示：(1) 西溪湿地公园社会经济可持续性和生态可持续性的空间分异明显，社会经济可持续性较好区域主要分布在公园边界区域，占整个公园面积的2.18%，而生态保护可持续性较好的区域主要分布在公园内部，约占39.50%；(2) 公园景观健康较好的区域分布在公园内部区域，占公园面积的25.06%；较差的区域分布在公园周边区域，以公园南边界附近分布面积较大；(3) 景观健康状态与景观要素的功能特征及其空间分布格局息息相关。

Spatial Differences of Landscape Health in Urban Wetland Parks: A Case Study of Xixi Wetland Park in Hangzhou

Landscape health was produced after ecosystem health and became a new research direction. The difference between landscape health and ecosystem health is their scales of study. The criterion of landscape health is to judge the maintenance of landscape. As the urban wetland park, it is important to keep sustainability of socio-economy and ecological protection. So the model of landscape health was established according to the coordination of social economy and ecological protection. The results showed that: (1) The maps clearly showed that the spatial differences obviously existed between socio-economy and ecological sustainability. Socio-economic sustainability and ecological sustainability with better grade covered 2.18% and 39.50% of the whole study area respectively. (2) Better landscape health area was distributed in the inner park and covered 25.06% of the park. (3) In this analysis, we found landscape health was closely related with landscape function and spatial distribution of the landscape.
