摘　　要：[目的]量化研究农牧交错带的生态系统服务功能及其价值。[方法]以典型农牧交错带内蒙古自治区兴安盟科尔沁右翼中旗为例,基于InVEST模型运行原理、研究区特点和数据可获得程度,从土壤保持、水源供给和水质净化3个主要方面对科尔沁右旗2000、2010和2019年3个时段的生态系统服务功能价值进行评估。[结果]科尔沁右翼中旗生态系统服务功能价值较大,2000、2010和2019年的生态系统土壤保持服务功能价值分别为30.54亿、31.88亿和32.79亿元,水源供给服务功能价值分别为100.69亿、105.19亿和87.40亿元,水质净化服务功能价值分别为1 685.54万、1 584.43万和1 698.02万元。[结论]基于InVEST模型对生态系统服务功能价值评估,不仅为北方农牧交错带生态系统服务功能重要性区域和综合生态区划分奠定了研究基础,也弥补了InVEST模型在我国北方农牧交错带生态系统服务研究内容和方法应用的不足。[Objective]To quantitatively study the ecosystem service functions and their values in the agriculture-pastoral ecotone.[Method]Taking the typical agricultural-pastoral ecotone in Horqin Right Middle Banner,Xing′an League,Inner Mongolia Autonomous Region as an example,based on the operation principle of InVEST model,characteristics of the area and data availability,this paper evaluated the value of ecosystem services in 2000,2010 and 2019 from the three main aspects of soil maintenance,water supply and water purification.[Result]The ecosystem service value was large.In 2000,2010 and 2019,the value of soil maintenance service was 3.054 billion,3.188 billion and 3.279 billion,respectively;the value of water supply service was 10.069 billion,10.519 billion and 8.74 billion,respectively;and the value of water purification service was 16.855,4 million,15.844,300 million and 16.980,200 million,respectively.[Conclusion]The value evaluation of ecosystem service function lays a foundation for the division of the important region and comprehensive ecological area of the ecosystem service function in the northern ecosystem,and makes up for the deficiency of the research content and method application of InVEST model in the ecosystem service in northern China.
