摘　　要：本文选择建瓯市闽北水土保持科教园作为试验区,选取4种具有典型代表性的土地利用方式,分析不同工程措施、不同植物措施对水土流失的影响。结果表明:从工程措施的蓄水保土效果分析,水平台地的水土流失治理效果比顺坡好;从植物措施的蓄水保土效果分析,都是茶园的情况下,种植百喜草的水土流失治理效果比未种草的好;从土地利用类型分析,都是种植百喜草的条件下,茶园水土流失治理效果比果园好;从土壤侵蚀的影响因素分析,4种小区的径流深、侵蚀量与雨量、I30关联紧密,主要降雨特征对产流产沙有显著影响。研究结果可为该区域水土流失防治提供参考。The North Fujian Province Soil Conservation Science&Education Park of Jian'ou City was selected as the test area for the study.Four typical and representative land use types were chose for the analysis of the impact on soil loss by different engineering and vegetation measures.The results show that,from the aspect of the water storage and soil conservation effects by the engineering measures,the soil conservation effect on the horizontal terraces is better than that of slopes;from the aspect of water storage and soil conservation effects by the vegetation measures,the soil conservation effect by plantation of Paspalum notatum Flugge is better than that of no grass in the tea garden;and from the aspect of land use patterns under the same condition of plantation of Paspalum notatum Flugge,the soil conservation effect in tea garden is better than that of orchard.Analysis on the impact factors of soil erosion show that,the runoff depth and erosion amount in the four test plots are closely related to rainfall and I,and the 30 main rainfall characteristics have a significant impact on runoff and sediment production.The study result will provide the reference for the soil erosion prevention and management in this region.
