摘  要:
以杨树纯林、杨树-沙棘混交林、紫花苜蓿草地为对象,对大凌河河滩地进行植物生态修复模式研究,结果表明:杨树纯林林地的土壤年风蚀量仅为0.21 kg·m~(-2),杨树-沙棘混交林林地为0.25 kg·m~(-2),紫花苜蓿草地为0.30 kg·m~(-2),而对照河滩耕地高达1.69 kg·m~(-2)。3种试验地的土壤年风蚀量均值分别较对照减少了1.48 kg·m~(-2)、1.44 kg·m~(-2)、1.39 kg·m~(-2)。植物生态修复效果显著。

摘  要:
The plants ecological restoration mode research was carried to Daling river flood land by taking Populus pure forest,Populus-Hippophae rhamnoides mingled forest and Medicago sativa grass land as objects. The result showed that the annual amount of soil erosion of Populus pure forest woodland was only 0. 21 kg·m~(-2),Populus-Hippophae rhamnoides mingled forest's was 0. 25 kg·m~(-2),Medicago sativa grass land's was 0. 30 kg·m~(-2),while the control flood land of soil erosion in the amount was up to 1. 69 kg·m~(-2). The annual amount of soil erosion mean value of three experimental field reduced 1. 48 kg·m~(-2),1. 44 kg·m~(-2),1. 39 kg·m~(-2)compared with the control respectively. The plant ecological restoration effect was remarkable.
