Abstract根据三个观测站多年的观测结果,揭示了在四川紫色土低山丘陵区,不同土地利用类型的土壤侵蚀强度的大小顺序是耕地、林地和封禁草地,人为活动是加剧土壤侵蚀率的最根本原因。雨季初期是各种土地可侵蚀性较大期。封禁草地和成林地的侵蚀率随雨强的变化不大。因此,防治该区水土流失,规范或禁止人为活动,加强雨季初期的管理,以及增加地被盖度理应是三大基本的措施。
Other AbstractThe continuous observed data from three fields experimental stations located at Sichuan Yanting,Nanbu and Pengxi respectively,reveals the magnitude order of erosion rate is the cultivated land,afforestation land and undisturbed grassland in hilly and mountain area of purple soil,and implicates human activity is the fundamental cause for the over erosion rate.The erodibilty is high at initial period of rainy season for various utilized land.The erosion rate of undisturbed grassland and matured afforestation land is not proportional to the rainfall intensity.Therefore,in the nature of things,regulating or prohibiting human activity,intensifying the management of initial period of rainy season and increasing the cover rate of land surface ale the major three basic measures for preventing the soil erosion.
