主要研究了塔里木河下游中段 ,随塔里木河下游应急放水 ,河滩地的胡杨和红柳种子出苗与根系吸水后重新发芽生长等自然恢复措施的同时 ,分析了河床自然淹水条件下林灌草甸土的水分 ,盐分和肥力变化状况及其对胡杨和红柳乔灌木植被种子出苗 ,和地下水位的升高对升灌木根系重新发芽生长的效果。根据对塔河下游定点观测取样分析结果来看 ,淹水林灌草甸土不但是自然恢复保护塔河下游绿色走廊的根本基础 ,而且是恢复与保护绿色走廊的一项有效措施。
This paper mainly studied the natural recovery measures such as emergent water discharge in the lower reaches of the Tarim River, emergent water discharge in the lower reaches of the Tarim River, emergence of Populus euphratica seeds and re-germination and growth of the roots after water absorption in the floodplain, The changes of soil moisture, salinity and fertility as well as its effects on seedling emergence of Populus euphratica and Hibiscus marsh shrub vegetation, and the effect of elevated groundwater level on the germination and growth of shrubs were studied. Based on the sampling analysis results of the fixed point observations in the lower reaches of the Tarim River, it is not only the natural basis for natural restoration and protection of the green corridor downstream of the Tahe River but also an effective measure to restore and protect the green corridor.
