Taken present cutivated land in the middle and lower reaches of Tarim river as the research object , and chosen 10 ecolosical index , this paper aims to set up a evaluation index system and model to evaluate the best community structure modes which are situable for vesetation restoration in varions eco-regions in the middle and lower reaches of Tarim river .

Arbuscular mycorrhizaes of common plants infection at the lower reaches of the Tarim River;

Ecological-economic values of the natural vegetation restoration after groundwater elevation at the lower reaches of the Tarim River;

Influence of seed morphology on the vertical distribution of a soil seed bank in the lower reaches of the Tarim River;

Factor analysis in environmental degradation at the lower reaches of Tarim river;

Dynamic change of groundwater after ecological water transport at the lower reaches of Tarim River;

Monitor of ecological response along lower reaches of Tarim River based on remote sensing;

Variation of groundwater level after ecological water transport in the lower reaches of the Tarim River in recent six years;

In the lower reaches of the Tarim River,it belongs to the warm-temperate arid climate,the annual solar radiation,sunshine duration,accumulated temperature ≥10 ℃ and average daily range of temperature vary in ranges of 5 692～6 360 MJ/m~2,2 780～2 980hours,4 040～4 300 ℃ and 13～17 ℃ respectively.

In this paper, the chemical properties of groundwater are studied during four times of transfusing stream water to the lower reaches of the Tarim River for regenerating the ecology so as to reveal the temporal and spatial response of chemical properties of groundwater to implementing the project of transfusing stream water along the Yengisu section.
