| 摘 要： | 以盐官、桑盆殿两水文站低潮位为特征值,反映钱塘江两岸治江前后约50年的排涝条件变化,该两站的低潮位随着江道主流长度、丰枯径流等自然条件而变化。最终北岸盐官的排涝条件与治江前比未恶化,略有改善;而南岸萧绍虞平原则明显得到改善,其主要措施是尖山河段形成微弯凹岸,不仅有利于排涝,也有利于建闸和建码头。实践证明钱塘江河口的治理是成功的。

| Abstract: | By using the monthly-averaged low water level from Yanguan and Sangpendian tidal stations,it presented the variation of draining condition in both sides of Qiantang estuary.The low water level varied with the natural plain configuration of the estuary and incoming runoffs,and also with the estuary regulation.The results indicated that the flood draining condition in the north bank improves slightly,but in the south bank improves remarkably.The main reason is that after many years'regulation,the reach from J... |
