Abstract:: Based on the observation in runoff plots experiment in Jinxian, Jiangxi Province, the effects of orchard, crop land, grass land, crop land and orchard compound model, grass land and orchard compound model compared with naked areas(CK) under different land use patterns on controlling water and soil erosion were analyzed and the best compound models of water and soil conservation profits on red soil sloping land areas were screened. Results showed that:(1) compared with bare areas, runoff decreased by 24.22%～46.83% in orchard, crop land, grass land model, 43.7% and 53.22% in crop land and orchard and grass land and orchard models, respectively;(2) soil erosion was decreased by 23.63%～78.30% in orchard, crop land, grass land model, 66.66% and 76.06% in crop land and orchard and grass land and orchard models, respectively, compared to naked areas;(3) the precipitation was positive correlated with surface runoff and water and soil loss, at the same rainfall, different models of surface runoff and soil erosion are different;(4) crop land and orchard models, grass land and orchard models are some good kinds of water and soil conservation tillage measures. Therefore, it is suggested that proper agro-fruit and agro-grass ecosystems should be established so as to further control soil erosion in red soil sloping land.
