喀斯特地区岩质边坡抗侵蚀植被恢复技术研究
|
摘要
对喀斯特地区裸露岩质边坡的绿化,传统客土喷播技术很难发挥作用。本文中采用新的抗侵蚀边坡植被恢复方法,通过研究修复后土壤理化性质和植被的变化对抗侵蚀喷播的效果进行综合效果评价。结果表明,抗侵蚀喷播能够有效保持水土、提高土壤养分含量、保持植物群里健康生长,可以为喀斯特地区岩质边坡植被恢复提供借鉴。
For the greening of bare rock slopes in karst areas, traditional guest soil spraying technique won't work.In this paper, a new anti-erosion vegetation restoration method was adopted, and the comprehensive effects of the anti-erosion spraying were evaluated by studying the physical and chemical properties of the soil and the changes of vegetation.The results showed that the anti-erosion spraying could effectively maintain soil and water, increase soil nutrient content, and maintain healthy growth of vegetation.This study has provided reference for the vegetation restoration for rock slopes in karst regions.
