中文摘要： 生态服务功能的研究已成为国际生态学和相关学科研究的前沿和热点。然而，目前关于生态系统服务功能或者价值的评价，大多仅将生态系统作为均一的整体来研究，较少考虑景观空间异质性的影响，对其评估方法的科学性也缺乏验证。本研究拟以上海市杨浦区为例，通过实地样方调查、观测和多源遥感影像相结合研究：1）基于绿地景观空间异质性（绿地面积、斑块内部特征和连通性的空间不均匀性和复杂性）的绿地综合生态服务功能评价方法；2）以绿地的降温效应为实例研究，对提出的综合评价方法与传统仅考虑绿地面积的方法进行对比分析，检验其科学性和有效性；3）评价在不同尺度下景观异质性对于绿地综合生态服务功能的影响，分析不同研究尺度对于评价方法的影响。总之，本研究提出了将景观异质性纳入绿地综合生态服务功能评价的方法并进行科学验证，可为评估绿地综合生态服务功能、合理规划布局城市绿地提供依据，具有重要的科学和应用价值。

英文摘要： Study on ecosystem services has become a hot and frontier research topic in Ecology and other related disciplines. While a large number of studies about assessing ecosystem services and their value have been published, most of them are based on the assumption of the linear relationship between ecosystem services and the amount of habitat area. Ecosystem is therefore believed to be homogenous, and its spatial heterogeneity has been rarely considered. Taking Yangpu District of Shanghai as an example, this research attempts to integrate landscape spatial heterogeneity, including the area of green space, the characteristics of patches and landscape connectivity, into the evaluation of ecosystem services of urban greening. Multiple sensors, GIS and field monitoring will be applied o the data collection and analyses. Furthermore, the cooling effect will be used to test the effectiveness of the proposed methodology by comparing with and without the considering of landscape spatial heterogeneity in evaluating ecosystem services. Finally, as landscape heterogeneity is significantly affected by the scale of data used in the analysis, this study will test the sensitivity of the proposed method to different spatial resolutions of SPOT-5 data. In summary, this study provides a way to consider landscape spatial heterogeneity in the evaluation of ecosystem services of urban greening which is essential for ecosystem services assessment and landscape planning.
