摘要:

毛乌素沙地治理是三北防护林工程的重要内容之一,运用生态系统单位面积生态服务价值当量表和敏感性系数模型,评价分析毛乌素沙地土地利用与生态服务价值之间的动态变化和特征,揭示生态服务价值受地类变化的响应情况。结果表明:1)2000—2020年毛乌素沙地的土地利用结构发生了明显的改变,集中表现为动态度为负值的草地与水域面积的不断减少和相应的建设用地面积的增加,这是造成总生态服务价值减少的关键因素;2)除水文调节、食物生产外,各项生态服务所产生的价值均呈现不同程度的下降趋势。对毛乌素沙地而言,草地在整体生态系统中的贡献率不容忽视。

Abstract:

The governance of the Mu Us Sandy Land is one of the key components of the shelterbelt program in northeast,north,and northwest China.Utilizing the ecosystem service value equivalent table per unit area and the sensitivity coefficient model,this study evaluates and analyzes the dynamic changes and characteristics between land use and ecosystem service value in the Mu Us Sandy Land.The research reveals the response of ecosystem service values to land-use changes.The results show that:From 2000 to 2020,there was a significantly changed in the land use structure of the Mu Us Desert,primarily characterized by the continuous decrease of grassland and water areas with negative dynamics and the corresponding increase in construction land area,which is a key factor leading to the decrease in total ecological service value.Apart from hydrological regulation and food production,the value generated by various ecological services has shown varying degrees of decline.Particularly,for the Mu Us Sandy Land,the contribution of grasslands to the overall ecosystem cannot be overlooked.

Key words: ecosystem service value, land use type conversion, Mu Us Sandy Land
