摘　　要：以洛阳市为研究对象,选取水源涵养、水土保持、生物多样性、防风固沙4项指标进行生态系统服务功能重要性评价,选取水土流失、土地沙化、石漠化3项指标进行生态敏感性评价。利用GIS技术,首先对各单项因子进行分析并得到其空间分布,再将其进行叠加综合,得到生态系统服务功能重要性和生态敏感性空间分布。最后依据区域主导功能并结合生态现状进行分区,划分为水源涵养、水土保持及生物多样性维护重要区,水土流失预防治理区,石漠化调控治理区,土地沙化调控治理区,城区生态治理区和生态恢复区6个区域,根据每个区域的不同特征提出相应的生态保护建议。Taking Luoyang city,Henan Province as the research area,four indicators including water conservation,soil and water conservation,biodiversity,and windbreak and sand fixation were selected to evaluate the importance of ecosystem services.Three indi⁃cators of soil erosion,land desertification,and rocky desertification were selected for ecological sensitivity evaluation.Using GIS tech⁃nology,the spatial distribution of each single factor was firstly analyzed,and then the spatial distribution of ecosystem service impor⁃tance and ecological sensitivity was obtained by superposition and synthesis.Finally on the basis of regional dominant function com⁃bined with the current situation of ecological zoning,the region was divided into 6 areas,including water conservation,soil and water conservation and biodiversity maintenance important area,soil erosion prevention and control area,rocky desertification control area,land desertification control area,urban ecological control area and ecological restoration area.The corresponding ecological protection suggestions were put forward according to the different characteristics of each region.
