摘　　要：被 mesophytes 种类主要统治的河边的森林的出现和发展与表面水仔细联系。因为到过去的 5 十年年里的 Tarim 河的更低的活动范围没有水分泌物，河边的森林严重地降级。在 2002 和 2003 的 Yingsu， Argan 和 Luobuzhuang 的监视数据的基于的在分析，效果再装 ofwater 被讨论。再装水的工程忽视事实控制在露面，而是对植被的地下水影响的焦点上开拓殖民地于的 Populus euphratica 的过程，这正在泛滥。泛滥的控制背离河边的森林开发的固有的法律，河边的森林的自然新生因此被检查。地下水上的河边的植物的反应范围高举极其狭窄、很河边的社区没被优化。因为 theirphysio 生态的特征被忽略，主导的种类的幼苗都没在充满区域被发现。然而，在溪流的附近的植被变化仅仅在浅地下水上反映 mesophytes 种类的需求为河边的植物的幼苗建立提供合适的产地的 water-re-chargingfails。再装 presentwater 计划是困难的认识到植被恢复。The occurrence and development of riparian forests which are mainly dominated by mesophytes species relate closely with surface water. Since there is no water discharge to the lower reaches of Tarim River in past 5 decade years, the riparian forests degrade severely. Based on the analyses of the monitored data of Yingsu, Argan and Luobuzhuang in 2002 and 2003, the effect of water-recharging is discussed. The water-recharging project neglects the fact that that it is flooding that controls the process of Populus euphratica colonizing on the bare surface, but focuses on groundwater influence on vegetation. The flooding control deviates Inherent laws of riparian forests development, so the natural regeneration of riparian forests is checked. The response scope of riparian plants on groundwater uplift is extremely narrow, and most riparian communities have not been optimized. No seedlings of dominant species are found in flooding areas because their physio-ecological characteristics are ignored. The vegetation changes in vicinities of stream only reflect the demand of mesophytes species on the shallow groundwater, however, the water-recharging fails to provide suitable habitats for the seedlings establishment of riparian plants. The present water-recharging scheme is difficult to realize vegetation restoration.
