摘　　要：生态系统服务的空间流转研究是生态系统服务研究的重要部分,对于制定区域生态补偿标准具有重要意义。为了衡量地区生态系统服务流转到外部区域的相对价值大小,提出了地区比较生态辐射力概念,利用断裂点公式、指数距离衰减函数,衡量比较生态辐射力的大小。基于南京市主体功能区研究,定量研究南京市各保护型区域的生态系统服务对各开发型区域的辐射力,计算出各开发型区域从不同保护型区域提供的生态系统服务价值比例。结果表明:高淳县、江宁区、溧水县对于白下区、秦淮区比较生态辐射力相对较大,六合区对于鼓楼区、下关区比较生态辐射力相对较大,浦口区对于鼓楼区、秦淮区的比较生态辐射力相对较大。以白下区为例,提出了南京市实施生态补偿建议,根据白下区从外部保护型区域获得的生态系统服务总量,在其提供的生态补偿金中,浦口区、江宁区、六合区、溧水县、高淳县应分别获得总额的22.76%、22.67%、21.50%、17.27%与15.80%。Studies of the spatial transfer of ecosystem services are an important part present study shows that they can also contribute to both the construction of meaningful of ecosystem service research. The ecological compensation standards, and to the appropriate level of these in a particular situation. To determine the comprehensiveness and impact of ecosystem service value transfers in our study areas, we took two factors into consideration, namely, the distance to be covered and the effect that the value of the ecosystem services in each area has on the spatial transfer of those services. Then, we put forward the concept of regional comparative ecological radiation force and a relevant calculation method in order to measure the relative levels of ecosystem service value transfers from inner to exterior zones. Regional comparative ecological radiation force is defined as being the service providing zone impact on service receiving zones through the transfer of ecosystem services. This study used a gravity model, breaking point formula and an exponential distance reduction function to measure regional comparative ecological radiation force. Based on the Major Function Oriented Zone （MFOZ） planning system of Nanjing, we categorized 11 City Districts （including Jianye, Qixia, Xuanwu, Baixia, Qinhuai, Yuhuatai, Gulou, Pukou, Liuhe, Jiangning, and Xiaguan） and 2 Counties （ Gaochun and Lishuie） within the city into two zones; development zones and protection zones. The main differences between the two are that development space in the development zones is much larger than in the protection zones, and that conversely, protection zones have much more protection space than development space. Land use data show that Liuhe, Jiangning, Pukou, Lishui and Gaochun are protection zones, and that Jianye, Qixia, Xuanwu, Baixia, Qinhuai, Yuhuatai are development zones. We calculated the comparative ecological radiation force from different protection zones to the development zones, and the proportion of their ecosystem ser
