研究结果包括以下几个方面 :苦草、竹叶眼子菜和黑藻等沉水植物 ,莲、茭笋等挺水植物 ,满江红、凤眼莲等漂浮植物适于水体植物的恢复与重建 ;芦苇、千屈菜、垂柳和枫杨等在水库边缘相对严酷的环境中有较好的潜在适应能力 ;结合库缘植被恢复 ,建立防止岸坡遭受侵蚀的立体防护林带 ;陆生生态系统植被恢复与重建 ,应从退耕还林和考虑不同海拔高度植被的垂直地带性分布合理搭配植物物种入手。物种选择应符合特定的生态环境和具有经济效益 The results of this study include the following aspects: submerged plants such as bitter grass, Phyllostachys praecox and Hydrilla verticillata, emergent plants such as lotus and bamboo shoots, floating plants such as Azolla and Eichhornia crassipes are suitable for the restoration and reconstruction of water plants; Phragmites australis, weevil, weeping willow and maple poplar in the relatively harsh environment near the reservoir have better potential adaptive capacity; combined with the recovery of the reservoir edge of the establishment of the bank to prevent the erosion of the three-dimensional shelterbelts; Terrestrial ecosystem vegetation restoration With the reconstruction, we should start from the conversion of cropland to forest and take into account the vertical zonal distribution of vegetation at different altitudes with reasonable plant species. Species selection should be consistent with the specific ecological environment and have economic benefits
