【摘要】 本文根据恢复生态学和景观生态学的基本原理,遵循自然规律和经济规律,依据当地生态条件和地表流沙分布状况,从水土资源优化配置角度出发,结合沙地植物自然分布的趋水性特征,采取以封育措施为主,因地制宜适度造林种草育藻,构建了一种创新的乔灌草藻四为一体的综合快速复合治沙模式,初步实现了脆弱生态系统趋于稳定,生物多样性明显增加,沙尘暴危害被有效遏制的目标。更多还原

【Abstract】 In this paper,we analyzedthe ecological conditions of the studing area and the drift sand distribution.At the same time,we studied the distribution feature of the natural vegetation according to the growing tendency to the water in the sandland from the side of the soil and water resources ration.We studied the effection of fencing on recovering vegetation,and the technology ways of right site and right plantation,grown grass and inoculate the alga with cultivated.We put forward to the innovation models of controlling the drift sand in combination with the tree,shrub,grass,and bio-crust,basicing on the theory of restoration ecology and landscape ecology,abiding by the natural law and economic law.The models preliminary accomplished the goal of controlling sanddust storm,the weak ecological system was tending to stable,and the biological diversity significantlyincreased.更多还原
