摘  要:
三峡大坝于2003年正式运行,受水文节律变化的影响,近10年来,东洞庭湖洲滩成林杨树面积整体上呈现逐渐递减,杨树分布洲滩高程呈不断上升趋势。虽然引起东洞庭湖洲滩杨树规模及分布状况变化的原因多样,但东洞庭湖水文环境的变化是主要原因。湖区洲滩杨树种植面积的下降,将有助于促进湖区湿地原生植被的恢复。

摘  要:
Three Gorges Dam,which has started to operate from 2003,has caused huge hydraulic changes to downstream of the river and remarkable ecological impacts to East Dongting Lake.According to the survey,the poplar tree area showed a gradually decrease,while the elevation of poplar tree distribution tended to move to higher area in East Dongting lake in recent 10 years.Although many reasons contributed to those trends,the hydraulic changes of the lake caused by the operation of the Three Gorges Dam was one of the most important driving factors.In addition,cultivated area of poplar tree declining helps to promote wet land protection in East Dongting lake.
