Research on the Ecosystem Value of the Agriculture-pastoral Ecotone Based on the InVEST Model—Taking Horqin Right Middle Banner as an Example
[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 ex-ample,based on the operation principle of InVEST model,characteristics of the area and data availability,this paper evaluated the value of eco-system services in 2000,2010 and 2019 from the three main aspects of soil maintenance,water supply and water purification.[Result]The eco-system 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 bil-lion,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 e-cosystem 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 eco-system service in northern China.
