小流域综合治理应考虑地质因素

Geologic Factors Should Be Considered in Comprehensive Harnessment of Small Watershed

在小流域综合治理中,系统地考虑地貌、岩性、地层、构造、地下水、矿产等地质因素,积极地布设防治措施,对提高小流域综合治理的质量、有效地防治水土流失、充分利用水土资源、防止一些地方病等都有着十分重要的意义。本文通过一些典型实例论述了地质因素与小流域治理的关系。

In the harnessment of small watershed, systematically considering geologic factors such as geomorphology, lithology character , stratum, tectonics, ground water and mineral products as well as assigning prevention measures have great significance in increasing the quality of comprehensive harnessment of the small watersheds, preventing and controlling soil loss effectively, fully utilizing soil and water resources and preventing ende.mic diseases etc. Based on se-veral typical examples, this paper expounds the relation between geologic factors and the control of small watershed.
