通过参加河北省天津专区几个重点县社的河网化规划工作,我们着重地研究了除涝标准问题,蓄灌排系统的布置问题,地下水的利用问题和盐碱地河网化问题。兹将我们对这几个问题的意见提出,以供河网化规划的讨论和参考。(一)除涝标准问题河网化是平原洼涝地区消除水旱災害和综合开发水利资源的高级形式。河网化的土方量很大,而基本河网(即三级以下的河网)要占总土方量的80%以上。基本河网的中心任务
By participating in the river network planning work of several key counties in the Tianjin area of Hebei Province, we focused on the standard of waterlogging drainage, the layout of storage and drainage systems, the utilization of groundwater and the river network of saline-alkali land. We will put forward our opinions on these issues for discussion and reference of river network planning. (I) Standards for Waterlogging Regulation River network is an advanced form of eliminating flood and drought disasters and comprehensively developing water conservancy resources in plain and water-logging areas. The amount of earthwork in the river network is large, while the basic river network (that is, the river network below the third grade) accounts for more than 80% of the earthwork. The basic task of the basic network
