| 摘 要： | 根据梅山水库消落带地形、土壤及岩石裸露率等因子,将其划分为斜坡地、急坡地和岩石边坡3种立地,分别进行树种筛选和栽培措施研究。通过不同水位临界点各样地植物成活率和生长量对比,分析植物衰退及死亡的原因并找出替代树种。研究表明,随着坡位和海拔高度上升,植物常年受水淹时间越短,且水淹深度越浅,其植物长势提高,与此同时植物受干旱胁迫增加,植物长势于海拔119 m处达到最大值。相同淹水和干旱条件下,垂柳枝条萎蔫严重,死亡率约为55%;旱柳生长情况最好,成活率约为86%;该几种乔木树种成活率为旱柳水杉竹柳乌桕枫香垂柳,马尾松栽植于消落带上部未受水淹,因耐瘠薄而正常生长。

| Abstract: | According to the existing topography, soil test data, and the rock bareness degrees in the riparian zone of Meishan reservoir, we divided the zone into 3 sites, the ramp ground, steep slope and rock slope. Tree species selection and cultivation techniques were determined in the 3 sites based on the water level, survival rates of different plants, and the growth performance in dry and wet seasons. We also analyzed the causes of the tree death and decay to find alternative plant species. The results showed that the plant growth was different under different water levels. With the rise of altitude, the time of waterlogging became shorter and the water depth became shallower, the plant growth was promoted; however, the drought stress became seriously. The plant growth reached the maximum value at the altitude of 119 m. Under the same flooding and drought conditions, Salix babylonica performed poorly and could not adapt to the reservoir environment with ~55% of death rate. The best performance was obtained from Salix matsudana, with ~86% of survival rate. The order of the survival rate was Salix matsudana > Metasequoia glyptostroboides > bamboo willow >Sapium sebiferum > Liquidambar formosana > Salix babylonica. Pinus massoniana planted in the upper area of the riparian zone grew normally because of no flooding stress. |
