本研究采用室内实验和室外观测相结合的研究方法,建立微型小区观测黄连种植过程中各土地利用类型的土壤侵蚀状况;田间采样后室内分析,应用通用土壤流失方程预测黄连种植过程中各土地利用类型的土壤侵蚀量。结果表明黄连种植过程中,侵蚀主要发生在一年生连地和收连后的弃耕地和还耕地;黄连收获后种植三叶草明显地减少了土壤的侵蚀移动。同林地相比,耕地是石柱县主要的侵蚀源。田间观测表明黄连种植过程中,侵蚀主要发生在弃耕地和还耕地。 In this study, indoor and outdoor observation methods were used to establish the soil erosion status of each land use type during the cultivation of Coptis chinensis in microcommunities. After field sampling and indoor analysis, the general soil loss equation was used to predict the land use of Coptis chinensis Type of soil erosion. The results showed that during the growth of Coptis chinensis, the erosion occurred mainly in abandoned and cultivated land after annual and continuous cropping; planting clover after harvest significantly reduced soil erosion and movement. Compared with forest land, cultivated land is the main source of erosion in Shizhu County. Field observations showed that during the growth of Coptis chinensis, the erosion occurred mainly in abandoned farmland and cultivated land.
