Characteristics of soil nutrients loss under different land use patterns in Beijing during course of rain were studied. The results indicated that: (1) The surface runoff under different land use patterns had a logarithmic change tendency with the increasing of rain

which ordered grassland＞farmland＞woodland＞orchard. (2) The increasing range of soil erosion of grassland was larger

and farmland

woodland

orchard was lower

which ordered grassland＞farmland＞woodland＞orchard. (3) The surface runoff and interflow of grassland and farmland were significant higher than woodland and orchard (p＜0.05)

which ordered grassland＞farmland＞orchard＞woodland. (4) The sediment accumulation under different land use patterns had a exponential function change tendency with the increasing of rain

which ordered grassland＞farmland＞woodland＞orchard. (5) The nitrogen and phosphorus loss in water

sediment nitrogen and phosphorus loss and the total loss of nitrogen and phosphorus ordered grassland＞farmland＞orchard＞woodland. (6) The loss of nitrogen in runoff water

and the loss of phosphorus in erosive sediment under different land use patterns. (7) The total content of nitrogen and phosphorus under different land use patterns antecedent rainfall ordered grassland＞farmland＞woodland＞orchard. The sediment ratio of N/P was higher than that of ratio of N/P antecedent rainfall which indicated that erosion and sediment had an effect of nitrogen and phosphorus enrichment

and the nitrogen enrichment was higher than phosphorus enrichment

which the grassland had the most highest nutrients enrichment. (8) The sediment had a significant or extremely significant positive correlation with the nutrients of sediment

and had a different positive correlation with the nutrients of soil

which implied that the sediment yield could cause the increase of various kinds of nutrients.
