三峡水库蓄水运行后,洞庭湖区防洪形势遇特殊洪水年份仍非常严峻,水资源利用问题也比较突出。利用不同年代水文资料,研究了不同时期洞庭湖洪水位、常水位和枯水位的变化特性;分析了造成水位变化的原因,包括长江干流水位变化、洞庭湖泥沙淤积、湖区径流变化、湖区蓄洪安全建设滞后导致分蓄洪无法实施以及人类活动。阐述了水位变化对防洪和水资源利用带来的不利影响,提出了应进一步完善湖区防洪体系和水资源配置工程建设的建议。

After the impoundment of Three Gorges Reservoir, the flood control situation in Dongting Lake region is severe in special flood years, and the water resources utilization problem is prominent. The variation characteristics of flood level, normal water level and low water level of Dongting Lake in different periods were researched by using hydrological data in different dec-ades. The causes for water level variation were studied, including water level variation in Yangtze River stem, sediment deposi-tion in Dongting Lake, runoff variation in the region, unable to carry out flood diversion and storage due to the lag of flood storage area construction, and human activities. The negative impact of water level variation on flood control and water resources utiliza-tion was demonstrated. The suggestions for further improving flood control system and water resources allocation projects were put forward.
