摘　　要：长江引排水是江苏省水资源的重要来源,同时也是旱、涝灾害的主要影响因素[1],本文通过长江引排水、调水进行定性和定量分析,揭示了江苏省水资源虽然十分丰富,但时空分布不匀,调蓄容量有限,供需平衡存在一定矛盾的现象,工程调度需统筹防洪、用水、蓄水等各方面需求,进一步合理运用和优化调度方案,在确保防汛安全的前提下,及时建立汛限水位动态调整机制,增强水资源统筹调度保障能力,同时对入江河流进行水质状况评价,并计算了入江河道中劣Ⅴ类河道的入江水量,为水资源开发利用、计划用水和长江大保护等管理工作提供参考数据。The diversion and drainage of the Yangtze River is an important source of water resources in Jiangsu Province,and it is also the main influencing factor of drought and flood disasters[1].Through the qualitative and quantitative analysis of the diversion and drainage and water transfer of the Yangtze River,this paper reveals that although the water resources in Jiangsu Province are very rich,the temporal and spatial distribution is uneven,the regulation and storage capacity is limited,and there are certain contradictions in the balance of supply and demand.The project dispatching needs to coordinate the needs of flood control,water use,water storage and so on.Further reasonably use and optimize the dispatching scheme,timely establish the dynamic adjustment mechanism of flood limit water level on the premise of ensuring flood control safety,enhance the guarantee capacity of overall dispatching of water resources,evaluate the water quality of rivers entering the river,and calculate the inflow of inferior class V rivers in the river entering the River,so as to provide reference data for the management of water resources development and utilization,water planning and great protection of the Yangtze River.
