    摘要:

    该文论述了金衢地区水土流失现状,分析了丘陵山地土壤退化的主要原因是水土流失。指出:由于森林采伐量超过生长量,森林植被屡遭破坏,森林的生态功能未能发挥,导致水土流失加剧。水土流失面积占全区丘陵山地面积的1/3以上,侵蚀模数超过2 500t/(km~2·a)。为了防治水土流失和土壤退化,建立红壤丘陵山地良好的生态环境,应实行生物措施和工程措施相结合,坚持边治理边开发和开发与治理相结合的原则。

    Abstract:

    Current situation of soil and water loss and producing reasons of soil degradation in Jinqu region were described in the paper. The soil degradation was caused by soil and water loss and more severe soil and water loss resulted by forest cutting over its growth rate.The overcutting lost the ecofuction of the forest.The arear of soil and water loss was over one-third of total arears of hill and mound land,and modulus of erosion was over 2500t/km2.a.In order to prevent soil and water loss and soil degeneration and to establish a better ecosystem in the red soil hilly region,both combination of bilolgical and engineering measures and princeple of combination of controling the loss and developing the land resoures should be take into accout at the same time.
