中文摘要：

绿色空间生态服务（green space ecosystem services，GSES）与地形因子（坡度、海拔、坡向）有密切的关系，研究其关系对区域生态服务功能的修复、完善和可持续发展具有重要意义。通过奉化市绿色空间地类的划分和生态服务的计算模型获得GSES的价值。利用GIS技术提取坡度、海拔、坡向3个地形因子，同时分别获得每个因子对应的GSES值，最后选择Spearman相关分析模型对GSES价值与地形因子值进行检验。结果显示，奉化市GSES价值在空间上呈现出东北部、东南部GSES价值最低，西部、南部GSES价值较高的格局；GSES价值与地形因子的相关性强度表现为：坡度〉海拔〉坡向。同时由于海拔、坡度和坡向的变化导致温度、水分和太阳辐射在地表发生变化，并致使生态服务空间格局随海拔、坡度和坡向的变化呈现一定的规律性。

英文摘要：

The green space ecosystem services （GSES） is closely related to topography factors （altitude, slope grade, slope aspect）. The value of GSES was got by dividing land use type and using related calculation model in Fenghua city. Besides, GIS technology was used to extract three terrain factors about altitude and slope grade as well as slope aspect, al the same time, relevant values of GSES of three terrain factors were obtained respectively. Spearman correlation a- nalysis model is applied to examine correlation between value of GSES and topography factors. Results show that the val- ue of GSES is the lowest in the Northeast and Southeast in Fenghua, and is higher in the West and the South. The cor- relation intensity of three terrain factors and the value of GSES is slope〉 elevation〉 aspect, which indicates that the value of GSES changes with some rules in the variation of al-titude, slope grade and slope aspect and it would change so lar radiation ,temperature and water.
