摘要
利用坡面人工径流小区,对比了10种藤本植物地的植被覆盖度、径流量、土壤侵蚀量和土壤抗蚀性能。结果表明,与裸地相比,藤本植物可以增加土壤的覆盖度,减少降水的径流量,减少土壤侵蚀量,其中以地枇杷、爬山虎、扶芳藤的效应最为明显;藤本植物还可以提高土壤的抗蚀性,其中地枇杷地崩解所需时间最长,有效根密度最大,水土保持效果最好。
It contrasts the vegetation degree of cover,rainfall-runoff,soil erosion quantity and soil anti-erodibility of 10 species of liane through artificial slope runoff plots.The outcomes show that comparing with uncovered land,the liane can increase the degree of cover of soil,reduce the runoff depth of precipitation and reduce the amount of soil erosion,of which,the effect of Ficus tikoua,Parthenocissus tricuspidata,Euonymus fortune bine are the most obvious and;liane also can increase soil anti-erodibility,of which,the required time for soil broken of Ficus tikoua land is the longest,effective root density the maximum and the effect of soil and water conservation the best.
