| Abstract: | Through analysis of the effects of harnessment in various types of experimental small watersheds, this paper summarized the main ways for harnessing earthy and rocky mountainous area according to the characteristics of soil loss in these areas. These ways include construction of base farmland and improvement of sloping farmland, engineering afforestation and protection, .development and utilization of resources of plant coverage, management and utilization of surface runoff, rational adjustment of the structure of land use, construction of gully protection projects, prevention and harnessment of new soil loss, etc., combining with . the experimental models, the author discussed, the main measures of harnessment and their benefits. |
