摘要: 摘要:通过对汉水流域退耕还林地5种5年生林分的典型配置模式进行调查和水土流失监测分析.认为不同配置模式其生物生产量及水土流失状况各不相同.其结果为:不同配置模式生物量排序依次为竹林〉杨树林〉杉木林〉松树林〉椿树林。不同配置模式总生产力比较的结果与生物量的结果基本一致。且枯枝落叶层现存量与总生产力呈显著正相关。地表径流总量及泥沙量依次为竹林〈松树林〈杨树林〈杉木林〈椿树林。

Abstract: By on Han River basin converting also woodland 5 species 5a health forest min of typical configuration mode for investigation and soil erosion monitoring analysis,think different configuration mode its biological production and the soil erosion status the does not same,its results for: different configuration mode biological volume sort turn for bamboo〉Shulin Yang〉 Chinese fir forest〉pine forest〉chunshu forest.Results of the comparison of different configuration modes total productivity and biomass results are basically the same, and floors of the existing demand and total productivity is significantly positive.Surface runoff and sediment of the total followed by bamboo〈pine forest〈Shulin Yang〈Chinese fir forest〈ehunshu forest.
