为了全面查清房山区小流域主沟道现状,掌握小流域主沟道水文形态特征,开展了第一次小流域主沟道水文形态调查。主要针对房山区境内因坡面径流冲刷土体、切割地表而形成的侵蚀沟道展开调查,查清侵蚀沟道的分布位置、数量以及沟道的形态特征和发展状况,把握现有沟道内的自然植被以及人为破坏情况,为后期小流域主沟道治理提供依据。
In order to comprehensively ascertain the status quo of the main channels in the small watersheds in Fangshan District and to grasp the hydrological features of the main channels in the small watershed, the hydrologic morphology of the main channels in the small watersheds was investigated. Mainly for Fangshan District due to runoff erosion due to slope runoff, cut the surface of the formation of the erosion channel to investigate and find out the location of the distribution of erosion channels, the number and shape of channel characteristics and development status, grasp the existing channel Natural vegetation and man-made damage, provide the basis for the governance of the main channels in the later watershed.
