毛乌素沙地不同治理措施植被恢复效果分析

Analysis on Vegetation Restoration under Different Management Measures on Maowusu Sandy Land

从群落数量结构与干物质生产方面对刘家窑头流域赵家塘不同治理措施下的植被恢复效果进行初步分析。结果表明:林草复合措施植被恢复效果最好,灌木林地植被恢复优于乔木林地,杨树纯林地效果较差;草方格固沙能使植被迅速恢复;喷撒化学固沙剂对迎风坡植被恢复的效果较为显著。

From the viewpoints of population quantitative structure and biomass production,the vegetation restoration of Liujiayaotou Watershed at Zhaojiatang under different management measures was analyzed.The results showed that the integrated tree-grass planting had the best effect on vegetation restoration.The vegetation restoration on shrub land was better than that on high tree land.The effect was worse on pure poplar land.Sand-fixing by checkerboard fence could accelerate the fast restoration of vegetation,and spraying chemical sand-fixing agents had obvious effects on vegetation restoration on the slope facing the wind.
