不同时间尺度的鄱阳湖生态水位研究
|
摘要
为支撑鄱阳湖水资源科学调控,本文提出了湖泊年、月、日尺度生态水位的概念,不同时间尺度湖泊生态水位均包括最低生态水位、适宜生态水位、最高生态水位.采用频率曲线法分析了鄱阳湖年、月、日尺度生态水位.在年尺度下,鄱阳湖最低生态水位、适宜生态水位、最高生态水位分别为12.07 m、13.40 m、15.15 m.湖泊年、月、日尺度生态水位反映了湖泊生态系统在不同时间尺度下对水位的不同需求,建议由年尺度、月尺度、日尺度下的水位资料序列统计分析相应尺度下的生态水位.
The concepts of lake ecological water levels at yearly,monthly and daily scales were proposed to support scientific water resources regulation of the Poyang Lake. The lake ecological water levels at different time scales include minimum,suitable and maximum ecological water levels. The frequency curve method was applied to analyze the ecological water levels at yearly,monthly and daily scales of the Poyang Lake. At yearly scale,the minimum,suitable and maximum ecological water levels of the Poyang Lake are 12. 07 m,13. 40 m and 15. 15 m,respectively. The lake ecological water levels at yearly,monthly and daily scales reflect the various requirements of lacustrine ecosystem for water levels at different time scales.Water level data at yearly,monthly and daily scales is suggested to be applied to analyze the ecological water level at corresponding time scales.
