滇东北不同退耕还林类型生物生产量及水土保持效益分析
- Title:
- Analysis on the Biological Production and Soil and Water Conservation Benefit Under Different Types of Returning Farmland to Forests in Northeastern Yunnan Province
- Keywords:
- northeastern Yunnan province; returning farmland to forests; biological production; soil and water conservation
- 分类号:
- S157;X171.1
- 摘要:
- 通过对滇东北河谷区退耕还林地5种5a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>刺楸林>杉木林>紫茎女贞林>车桑子林。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<刺楸林<紫茎女贞林<杉木林<车桑子林。
- Abstract:
- After observation and analysis on 5 complex planting models (5-year-old) of eco-economic forest for returning farmland to forests in northeastern Yunnan province,the results showed:the biomass under different model had the order as Bamboo forest>Kalopanax septemlobus forest>Fir forest>Ligustrum purpurascens forest>Dodonaea viscosa forest,the productivity under different mode showed the similar result and had significant positive correlations with standing stocks of forest floor,the surface runoff and sediment had the order as Bamboo forest<Kalopanax septemlobus forest<Ligustrum purpurascens forest<Dodonaea viscosa forest.
