Plateau dry and warm valley hydropower development area vegetation recovery method

The invention discloses a plateau dry and warm valley hydroelectric development area vegetation restoration method, and provides artificial grassland planting and fruit-bearing forest planting for vegetation restoration based on the ecological conditions that the dry and warm valley in southeast of Tibetan has many gravels and drought climate. According to the artificial grassland planting method, the combination of alfalfa and oat is selected, the survival rate is high, and the current coverage reaches 90% or above; walnuts are selected for planting through fruit-bearing forest building, the survival rate is 90% or above, the whole test area is basically covered with vegetation, the treatment effect is good, and vegetation recovery of the hydropower station slag yard in the ecologically fragile area can be accelerated. 本发明公开了一种高原干暖河谷水电开发区域植被恢复方法，基于藏东南干暖河谷多砾石、气候干旱的生态条件，提出人工草地建植和经果林建植进行植被恢复。本发明的人工草地建植选择苜蓿与燕麦组合，成活率较高，现状盖度达90%以上；经果林建植选用核桃进行种植，成活率均在90%以上，整个试验区基本覆盖植被，治理效果良好，能够加快生态脆弱区水电站渣场的植被恢复。
