塔河下游胡杨和红柳自然恢复的土壤条件初步研究

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廓的根本基础，而且是恢复与保护绿色走廓的一项有效措施。

Preliminary Research On Soil Conditiom of Diversiform- leaved Poplar And Rose Willow Natural Recovering On the low Reaches of Tarim River

The article mainly researches on the middle section of the low reaches of Tarim River,along with emergency turning on water of the low reaches of Tarim River,after seeds of diversiform-leaved poplar and rose willow emerging and root system absorbing water resprouting growing and etc natural recovering measures,at same time analysing under the riverbed natural submerging conditions,changing status of moisture content,fertility of soil and salt content of shrub forest medow soil and for the bush vegetation seeds of diversiform-leaved poplar and rose willow emerging and groundwater level rising for respronting and growing effectiveness of arbor and bush root system.According selected points observating and sampling analysing result of the low reaches of Tarim River.The meadow soil of flooding forest is not cardinal base of natural recovering protection of green corridor on the low reaches of Tarim River,but also a effective measure of recovering and protecting green corridor.
