沙漠作为重要的生态系统和宝贵的自然资源,其产业发展也具有巨大潜力,探索沙漠生态产品价值实现路径,有助于沙漠地区生态保护和产业发展。文章以乌兰布和沙漠(磴口县范围)为研究区域,构建基于生态系统生产总值(GEP)核算的生态产品价值实现成效评估模型,开展评估研究。结果表明:(1)2020年磴口县GEP为107。05亿元,为当年GDP的1。85倍;防风固沙是磴口县生态系统的核心服务功能,占当年GEP的66。05%。(2)2010-2020年,磴口县GEP提高了 1。74倍,其中生态文化价值增速最快(182%),生态调节价值增幅最大(30。24亿元);GEP数值和范围不断扩大的主要驱动因素是沙金套海苏木等区域的森林和草地面积增加。(3)10a间,绿金指数(1。77)、生态产品初级转化率(23。07%)、生态产品价值占比(21。27%)和生态文化价值占比(1。80%)的平均值均偏低,生态产品价值实现程度有待提升。此外,该文还进一步探究了土地利用变化对生态产品价值的影响,以便揭示GEP变化的根源,从而可以有效保护生态环境,实现区域经济发展与生态建设相协调。
Assessment of the Degree of Realization of Ecological Product Value in Desert Areas
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.
