Eco-environmental responses of the lower reaches of Tarim River to the emergency water deliveries

In the past 30 years,water has ceased to flow in the 357 km lower reaches of Tarim River,and water must be de livered there emergently for resuing the environmental condition,which is a rare worldwide case of ecosystem recovery and re-habilitation in the deteriorated river basin.In this context,this article uses a great deal of monitored data from the eco-environmental baseline investigations and the methodologies of the river hydraulics,the groundwater dynamics and the vegetation ecology to analyze the law of water transportation,transformation and consumption along cross the river course and in the vertical profile of the river course,by following the mail line from water consumption along the river course the dynamic changes of groundwater table and the vegetation recovery. It contains scientific analyses of the three dimensional eco environmental responsive effect and vegetation recovery impacts on the emergent water deliveries,thus lays theoretical and practical foundation for creating and perfecting the evaluation system for the supplementary water delivery,the ecological recovery and rehabilitation of the damaged eco-environmental systems in the arid areas,mean while,provides the important technical support for the comprehensive improvement of the Tarim Basin.
