| 摘 要： | 通过对浙-闽丘陵区土壤侵蚀现状调查、分析研究,揭示了浙-闽丘陵区土壤侵蚀的严重性,提出了浙-闽丘陵区土壤侵蚀的主要影响因素:降雨条件;地形;地表松散的堆积物;植被的覆盖程度。降雨丰富且集中,山高坡陡,地表易流失的土壤,植被的严重破坏等,为该地区的土壤侵蚀提供了条件。最后,本文提出了浙-闽丘陵区土壤侵蚀防治对策应以生物措施为主,生物、工程、耕作密切结合。生物措施主要为植树种草;工程措施是改变小地形,以达到蓄水、保土的目的;耕作措施主要是改变乱开荒的做法,摒弃不合理的耕作方式,禁止陡坡开垦。不同地区应根据实地情况合理防治,采用小流域综合治理。不仅要根据影响因素来制定防治对策,也应该因地制宜。

| Abstract: | Zhejiang-Fujian hilly regions have suffered soil erosion for a long time.Recent investigation shows that soil erosion in this region is largely influenced by rainfall,landform,nature of superficial deposits and vegetation coverage.It is found that soil erosion occurs in the areas intense rainfall,abundant loose deposits,steep slope,and little vegetation coverage.Based on the investigation,countermeasures against soil erosion in this region are suggested,including bio-engineering,triming of slope,vegetation,changing of bad farming style,as well as regulation to prohibit farming on steep slope.It is also suggested that measures to be taken should include the censideration of local conditions both physical and social-economical. |
