摘要: 研究草地防风固沙功能及价值具有紧迫而又现实的意义。根据内蒙古西乌珠穆沁旗草地生态系统实际情况,对该旗草地防风固沙功能及价值核算方法进行了研究,以评估其草地防风固沙量及价值。研究结果显示,2000、2005、2010年,全旗草地减少土壤风蚀损失量分别为7.12×10^-7、7.12×10^-7、7.13×10^-7t;减少土壤风蚀退化面积分别为10 549.05、10 540.98、10 558.44 hm^2;防风固沙功能价值分别为27383.11万元、27 722.20万元、28 350.64万元,2000—2005年,该旗防风固沙功能价值提高1.24%,2005—2010年,防风固沙功能价值提高3.53%。

Abstract: It is of urgent and realistic significance to assess the wind-break and sand-fixing function value of grassland. Based on the actual situation of grassland ecosystem in West Ujimqin Banner of Inner Mongolia, the wind-break and sand-fixing function and value counting method of grassland in this region was studied. The results showed that in the years of 2000, 2005 and 2010,the reduction of soil erosion loss of grassland in West Ujimqin Banner was 7.12 ×10^-7, 7.12 ×10^-7, 7.13 ×10^-7t, respectively; the reduction of soil erosion degradation area of grassland this region was 10 549.05, 10 540.98, 10 558.44 hm^2, respectively; the value of wind-break and sand-fixing function of grassland this region was 273.83 million RMB Yuan, 277.22 million RMB Yuan and 283.51 million RMB Yuan. From 2000 to 2005, the total value of wind-break and sand-fixing function in West Ujimqin Banner was increased by 1.24%, and from 2005 to 2010, the total value of increased wind-break and sand-fixing function in this region was increased by 3.53%.
