摘要
2000a来,长江荆江河段的洪灾与治理一直是举国关心的问题。本文通过对历史时期荆江洪灾史料的分析,发现荆江洪灾多数发生在气候比较寒冷时期,特别是在寒冷时期中的温暖期内。荆江洪灾的发生主要与上游洪流水量过猛有关,其次是由本区雨季连续阴雨和暴雨所造成。成灾的基础是河间平原地区的相对沉降,造成泄洪不畅。治理荆江洪灾的主要途径可考虑分洪出流措施。
The flood and its control of Jingjiang is a significant problem which all people of Chinaconcerned. According to the statistical data, there occurred about 174 floods in this area from 190 B. C. to 1980 A. D. , most of which broke out in the cold phases of the historical climate, especially in the relative warm stages of the cold phases. Major cause mechanism is due to the great quantity of flood water from the upper course of the Yangtei River, protracted rain and torrential rain in the rainy season and relative subsidence of alluvial plain in Jingjiang area. The method of flood discharge may be considered in the control of floods in Jingjiang area.
