花岗岩侵蚀区植被层次结构优化模式研究
- Title:
- Research on the Optimization of Vegetation Stratum Structure in the Granite Soil Eroded Region
- Keywords:
- granite soil eroded region; vegetation stratum; structure optimization; the analytic hierarchy process
- 摘要:
- 通过在花岗岩侵蚀区组建不同层次结构的植物措施，对不同结构模式水保生态经济效能进行调查，并利用层次分析法对各模式的水保经济效能进行综合评价。结果表明：花岗岩侵蚀区的植被层次结构最佳模式是乔灌草结合的三层结构，它的生物量、拦截径流和减少土壤侵蚀能力最大，其次为灌草结构，再次为乔灌、乔草结构，最差的为乔木纯林。
- Abstract:
- The soil and water conservation effects and economic benefits from different vegetation constructed in the granite soil erosion region was investigated to obtain the vegetational vertical structure impact on the soil loss control and ecologic improvement. Based on the investigation, comprehensive evaluation was made through of the analytic hierarchy process (AHP). The results are as follow:The best vegetation model in granite soil eroded region is the tri-layered structure of tree,shrub and herb. Its biomass is the largest, its ability in interception runoff and reducing soil loss is also the greatest. The two-layered structure of shrub and herb is second. The two-layered structure of tree and shrub as well as the two-layered structure of tree and herb are third,and the one-layered structure of pure tree is the in ferior.
