【摘要】 提出建设迹地岩土坡的两种分类方法 :按成因分为土地开发类、采石取土类和开路填土类 ;按坡面物质组成又可将其划分为土坡、分化岩坡和岩石坡 3类。同时论述了各种类型迹地岩土坡主要性状和环境危害及严重性 ;概要介绍了迹地岩土坡的生态整治的主要技术探索 :(1)适生植物品种选择和组合配置模式 ;(2 )岩土坡面的植被营造技术 ;(3)抗旱瘠栽培措施。最后对技术应用效果进行总结更多还原

【Abstract】 Two ways of classification of rock/soil slope left by project slope is put forward.According to cause of formation,it can be divided to slope by land exploring,by rock and/or soil extracting,by road construction and rock/soil filling;it also can be divided by its surface material to soil slope,decayed rock slope and rock slope.The main characteristics of these slopes and their environmental hazard are stated.Three ways in slope ecological improving are put forward as follows:(1)plant species slection and its combination models;(2)techniques in revegetation on soples where soil is wanted;(3)anti-draught and anti-poor soil techniques.The effect of revegetation after applying these techniques are summarized .更多还原
