As an important ecosystem and valuable natural resources,desert has great potential for industrial development.Exploring the path to realize the value of ecological products in desert areas can stimulate the endogenous driving force of sand industry.This article takes the Ulanbuhe Desert(within Dengkou County)as the research area,constructs an ecological product value realization effectiveness evaluation model based on Gross Ecosystem Product(GEP)accounting,and conducts evaluation research.The results show that the GEP of the County in 2020 is 10.705 billion yuan,which is 1.85 times of the GDP of that year;wind and sand control is the core service function of the ecosystem,accounting for 66.05％of the GEP of that year.From 2010 to 2020,GEP increased by 1.74 times,with the fastest growth rate in ecological and cultural values(182％)and the largest increase in ecological regulation values(3.024 billion yuan);the main driver of the expanding GEP val-ues and scope was the increase in forest and grassland areas in areas such as the Sargent Settlement Sumu.Over the past 10 years,the average values of green gold index(1.77),primary conversion rate of ecological products(23.07％),value of ecologi-cal products(21.27％)and value of ecological culture(1.80％)are seriously low,which indicate that the value realization of ecological products needs to be improved.In addition,this article further explores the impact of land use change on the value of ecological products,in order to reveal the root causes of GEP changes,which can effectively protect the ecological environ-ment and achieve coordination between regional economic development and ecological construction.
