摘要
通过分析克孜河下游河岸林草区的水分运动和补给条件,对生态系统可能利用的水资源量与生态需水量、生态耗水量进行盈亏分析,计算河岸林草生态需水量和生态耗水量,预测水库修建后天然植被的生长状况。分析结果表明,水库修建后在满足流域内用水时,对下游河岸林草植被提供的生态用水增加,实际径流补给量超过濒临生长胁迫状态生态耗水量,有利于河岸林草区植被的恢复和生长。
Through analyzing the moisture movement and supply conditions of the riparian forest and grass area in the downstream of Kirgiz River,the profit and loss analyses are made for the volume of water resources,ecological water demand and water consumption to be able to use in ecological system,and the ecological water demand and water consumption for the riparian forest and grass are calculated,then the growth conditions of the natural vegetation after Kalabeili Reservoir bulldings are forecasted.The analysis results show that in the meantime the water consumption in the basin is satisfied after the reservoir building,the ecological water consumption for the riparian forest and grass vegetation is increased,and the practical water supply from runoff surpasses the ecological water consumption closing to growth stress state,which would be favorable for the resumption and growth of the vegetation in the riparian forest and grass area.
