摘要
鄱阳湖是我国最大淡水湖泊,湖泊水文节律变化显著影响着湖区生产生活、生态环境,但界定标准尚未形成统一认识。综合考虑水位变化规律、湖盆形态特点、水资源利用等特征指标,探讨鄱阳湖丰、平、枯水期界定标准。结果表明:以星子站作为鄱阳湖代表性测站,当星子站水位大于17.00 m时为丰水期,13.01~16.00 m为平水期,小于12.00 m(含12.00 m)为枯水期,16.01~17.00 m为平-丰过渡期,12.01~13.00 m为枯-平过渡期。枯水期多发生在10月下旬至次年4月上旬,发生日数平均为142 d;丰水期多发生在7月上旬至8月中旬,发生日数平均为40 d;平水期多发生在4月中旬至6月下旬、8月下旬至10月中旬,发生日数平均为117 d。
Poyang Lake is the largest fresh water lake in China,and its hydrologic rhythm change plays a significant impact on the production,living and ecological environment of the lake area,but the definition standard has not yet formed a unified understanding.This paper discussed the definition standard of wet season,normal season and dry season in Poyang Lake based on the characteristic indicators of water level change law,lake basin morphology and water resources utilization.The results show that:when the water level of Xingzi gauging station is higher than 17.00 m,the lake belongs to wet season;13.01-16.00 m belongs to normal season;less than 12.00 m(including 12.00 m)belongs to dry season.When water level is 16.01-17.00 m,it is normal-wet transitional season,and 12.01-13.00m is dry-normal transitional season.The dry season mostly appears from the last ten days of October to the first ten days of April of the next year with an average of 142 days;the wet season mostly occurs from the first ten days of July to the middle of August with an average of 40 days;the normal season mostly occurs from the middle of April to the last ten days of June and from the last ten days of August to the middle of October with an average of 117 days.
