高边坡截水少,不能满足植物的水生态位要求是高陡边坡植被难以生长的重要原因,本研究利用生态位原理进行耐旱护坡物种的筛选;仿效自然状况下高陡边坡坡面的坑洼部分有少量植物生存的事实,采取人工刻挖鱼鳞坑或者水平沟工程措施进行植物生长改良试验;利用湿法喷播技术,进行种植工艺试验;并经过初试、中试和两年的大面积施工实践,取得了良好的覆盖效果。
There is little water cut in high slope, which can not meet the requirement of plant’s water ecological niche. It is an important reason that the vegetation on high and steep slope is difficult to grow. In this study, we used the niche principle to screen the species of drought tolerant slope protection. Surface potholes part of the fact that a small number of plants to survive, artificial excavation fish scale pit or horizontal ditch engineering measures for plant growth improvement test; wet spraying technology, planting process test; and after the first test, pilot and two years The large area of construction practice, and achieved good coverage.
