摘要
由于自然力作用和人类活动,形成了大量裸露岩石边坡和仅有薄瘠土壤层的土石边坡。边坡植被恢复是在特殊立地条件下的植被恢复方式,水分是影响植被恢复效果和成败的关键因子。保水剂的应用能有效保持土壤水分,改良土壤结构,促进边坡上土壤生态系统结构和功能的恢复,有益于恢复后期边坡植被的自演替过程。从边坡生态因子、植物选择、保水剂的性能、用量和施用方式等多个方面对保水剂的应用作了初步探讨,以期有助于保水剂在边坡植被恢复实践中的合理应用。
Application of water retaining agent is a key factor that results in the success of vegetative recovery of slope. Water retaining agent can improve soil water condition and soil structure,thus accelerate growth and succession of plant in slope ecological restoration. This paper discussed the application of water retaining agent in vegetative recovery of slope from some aspects including slope ecologic factors,the selection of plant species,the character,quantity and the application method,thus to be helpful to its reasonably application.
