摘要: |
[目的]了解南宁至友谊关(简称南友)高速公路边坡绿化植被的水文效应。[方法]在全面踏查的基础上,选择了8个不同地点的7种典型群落类型,对其植被枯落物特性进行研究。[结果]三豆混播群落(S4)的枯落物蓄积量、吸水速率、有效拦蓄量均为最佳,分别为43.80 t/hm2、4 227 g·kg-1·h-1、55.18 t/hm2,而木豆群落(S1)的枯落物最大持水量、最大持水率最高,分别达到2 832 t/hm2、283.2%。[结论]三豆混播群落是南友高速公路边坡植被类型中水土保持效应最均衡的群落配置,具有良好的生态水源涵养及保持的功能,可推广种植,以维护边坡植被和土壤的水文生态功能。 |

Abstract: |
[Objective] In order to understand the hydrological effects of slope vegetation of Nanyou highway.[Methods] Based on the comprehensive survey, seven typical community types in eight different locations were selected to study the characteristics of vegetation litter.[Results] The litter accumulation, water absorption rate and effective interception rate of the three Leguminosae species mixed community (S4) were the best, which were 43.80 t/hm2, 4 227 g·kg-1·h-1, 55.18 t/hm2 respectively.The maximum water holding capacity and maximum moisture rate of the Cajanus cajan community (S1) were the highest, which were 2 832 t/hm2, 283.2% respectively.[Conclusion] The three Leguminosae species mixed community is the most balanced community configuration in the effect of soil and water conservation on the slope of Nanyou highway.It has good functions of ecological water conservation and can be promoted to maintain the hydrological ecological function of slope vegetation and soil. |
