| 摘 要： | 文章采用建径流小区定位观测方法,对富源县云南松次生林、华山松人工林、针阔混交林、次生灌丛和荒草地等主要植物群落进行水土保持能力的观测。分析表明:富源县的降雨量主要集中于5～10月,雨季降雨量占全年的86.48%,且降雨量主要是10mm以上的降雨产生;不同群落地表径流量、土壤流失量和侵蚀降雨次数依次均为荒草地>次生灌丛>云南松次生林>华山松人工林>针阔混交林,说明森林植被类型中针阔混交林保土保水能力最强,其次是纯林,在低效林改造和生态建设工程中应大面积推广混交林的营建。

| Abstract: | The construction of runoff plots positioning observation method, Yunnan pine secondary forest, Huashan pine plantation forest, mixed coniferous and broadleaf forest, shrubland and grassland, soil and water conservation capacity of main plant communities in the observation, analysis showed： rainfall in Fuyuan county mainly concentrated in 5 - 10, the rainy season precipitation throughout the year accounted for86.48%, and rainfalll0mm is mainly produced in different communities more rainfall; surface runoff, soil erosion and erosion rainfall times arc all grassland 〉secondary shrub 〉 Yunnan pine secondary forest〉 Huashan pine plantation forest 〉 needle and broad-leaved mixed forest, the Soil conservation and water conservation capacity of needle and broad-leaved mixed forest is the strongest in the forest vegetation types, followed by pure forest, mixed forest of construction should be popularized in large area in inefficient forest improvement and ecological construction projects. |
