摘要:
黄土高原淤地坝坝系建设对当地生态环境的改善有着重要作用.以王茂沟小流域为例,从自然灾害防治条件、林草覆盖度、土壤侵蚀程度、土地质量、人类生存和动植物栖息条件等方面对比分析了淤地坝坝系建设前后的变化,分析表明,淤地坝坝系建设在提高流域抗灾能力、促进并巩固退耕还林还草、改善局部小气候和人类及动植物栖息条件方面均发挥了重要作用,正确认识淤地坝的生态环境效益,对进一步推动淤地坝建设,实现黄土高原秀美山川建设有重要意义.
Abstract:
Silt dam plays an important role in improving the local environment on the Loess Plateau.Taking Wangmaogou catchment as a case,the changes before and after the construction of silt dams were contrasted from the disaster-preventing condition,forest and grass coverage degree,soil erosion intensity,soil quality,the living conditions of human being,animal and plant.The results show that the disaster-preventing capacity increased,the local microclimate and living conditions are greatly improved after the construction of silt dams,which also accelerate and consolidate the achievement of returning cropland to forest and grass.So that the role of silt dams is very significant in realizing graceful landscape on the Loess Plateau.
