摘要
利用子午岭天然次生林区,遭破坏林区和非林区的水文径流、泥沙观测资料及长时间序列气象观测资料,研究了人为破坏森林植被对径流、侵蚀、产沙的影响;植被破坏对洪涝灾害的影响;植被破坏与气候变化及植被破坏与土地退化的关系。作者认为人为破坏植被是导致黄土高原生态环境恶化的重要原因。
It has been researched that effect of forest destruction on runoff and sediment and flood hazards,relationship between forest destruction and climate change,and relationship of forest destruction and land degradation,using observated runoff and sediment data of hydrograph- ical stations in the forest area,destroyed area and non—forest area,long—time observation data of meteorogical station,and field investigating data ect.The authors consider that Vegetation be- ing destroyed by human’s activities is a key cause resuling in cco—environmental worseing in the loess plateau.
