摘要
为定量估算黄河流域荒漠生态系统防风固沙功能价值,以位于鄂尔多斯黄河流域的库布其荒漠生态系统流动沙地、半固定沙地与固定沙地为研究对象,针对其荒漠生态系统防风固沙量开展研究,对库布其荒漠生态系统的防风固沙功能价值进行评估核算.经核算,库布其荒漠生态系统2021 年防风固沙量为5.02×108 t,防风固沙服务价值量为 753×108 元/a,减少农田经济损失价值为16.06×108 元/a,减少草地经济损失价值为0.27×108 元/a,土壤营养元素保持价值为38.05×108 元/a,减少泥沙淤积灾害价值为3.01×108 元/a,减少交通运输经济损失价值为7.53×108 元/a.库布其荒漠生态系统具有极大的生态经济价值,其防风固沙功能对于鄂尔多斯黄河流域生态环境保护具有及其重要的作用.
Abstract
In order to quantitatively estimate the function value of the desert ecosystem in the Yellow River Basin,the study takes the moving,semi-fixed and fixed sandy land in the Kubuqi desert ecosystem in the Yellow River Basin of Ordos as the study object,researches wind prevention and sand fixation amount of the desert ecosystem,and evaluates and calculates the function value of the desert ecosystem in Kubuqi.According to the calculation,the amount of wind and sand fixation of Kubuqi desert ecosystem in 2021 is 5.02×108 t,the value of wind and sand fixation service is 753×108 yuan/a,the value of farmland economic loss reduction is 16.06×108 yuan/a,the value of grassland economic loss reduction is 0.27×108 yuan/a,the retention value of soil nutrient elements is 38.05×108 yuan/a,the damage value of reducing sediment deposition is 3.01×108 yuan/a,and the economic loss value of reducing transportation is 7.53×108 yuan/a.Kubuqi desert ecosystem has great ecological and economic value,and the function of wind prevention and sand fixation plays an important role in the ecological environment protection of the Yellow River Basin in Ordos.
