洞庭湖洪水规模与1995年自然降水分析

通过对１９９５年前汛期（４～７月）,四水流域,湖区,长江中上游等集水区间自然降水水平与洞庭洪水关系的研究,探讨洞庭湖早已出现的“高水位,低流量”异常现象的成因,在此基础上,揭示本世纪来,洞庭湖至今并达到１９５４年降雨规模,从而着重指出洞庭湖距世纪洪水的潜在危险。

ANALYSIS OF THE NATURAL PRECIPITATION IN 1995 IN FLOOD SEASON AND WATER LEVEL OF DONGTING LAKE

By analysing the correlation between the water level of Dongtin Lake and theprecipitation distribution during the: early flood season in 1995 (April-July) of the"Four-river valley", the area around Dongting Lake, the upper and middle reachesof the Yangtse River etc, we conduct further study on the unusual appearance andcharacters of "high water level in normal years" that has existed in Dongting Lakefor many years. on this basis we suggest that the flood of Dongting Lake has neverexceeded, even reached the scale of that in 1954, and emphatically point out thepotential danger of the flood of Dongting Lake beyond the century.
