, 2003 在黄土高原沟壑区的典型代表地区—王东沟小流域,根据高原沟壑区水土流失特点,开展生态环境建设和塬、坡、沟综合治理,林草覆盖率达45%,建成塬面农田防护林体系(占5%)、沟坡经济林体系(占15%)、沟谷水土保持防护林体系(占20%),草类占5%,林草配比合理。塬面以方田林网、道路网络和涝池群构成排蓄体系,基本作到水不下塬;平整沟坡土地、增加植被覆盖度,减少坡面径流,使水不带沙;沟谷用柳谷坊群分段拦蓄,作到泥不出沟。完成农村产业结构的调整,由历史上以粮食种植业为主的一元结构发展到粮、果 ...

, 2006 和参照区相比,减弱艾比湖地区地表抗风蚀能力,导致沙尘天气形成的不利因素首先是该区春季裸露的耕地和低覆盖度荒漠景观的分离度/破碎度较低。其次是较高的植被生态优势度、土壤中有机质含量和pH值,以及较差的土壤粒度分选性。而利于地表土壤稳定性的积极因素则是植被盖度、植物群落多样性及较粗的土壤质地。在查明艾比湖地区沙尘天气发生的地表条件基础上,可以通过生物的、物理和化学的方法使上述地表环境向抑制沙尘天气发生和保护土壤免遭风蚀的方向演替。通过人工种植草、木本植物和退耕还林还草,提高植被覆盖度。同时 ...
