淮北平原涝渍兼治的组合排水工程形式

由于淮北平原砂姜黑土区的气候、地形、地貌、水文地质、土壤等多方面原因，致使旱、涝、渍频繁，且涝渍灾害往往是紧密相连，先涝后渍，涝渍相随．造成大面积减产．甚至绝收，旱、涝、渍灾害一直困扰着本区的农业发展。通过试验及调查，从治理涝渍效果、提高农业产量、投入产出等方面进行综合分析，提出了几种适宜于本区的组合排水形式。

Combined Drainage Engineering Formations for Comprehensive Treatment of Water Logging and Waterlogged in the Northern Huai River Plain

Because of the climate, topography, physiognomy, hydrologic geology, soil and other factors of the sandy black soil area in the northern Huai River plain, disasters of water logging and waterlogged are very frequently happening in the region. Moreover, the disasters of water logging and water logged are joined to happen, which resulting in great area loss of crop production, and hindering the agricultural development. In this paper, through experiment and investigation, and comprehensive analyses of the effects of treatment, increases of agricultural production, input and output, several formations of combined drainage applicable for this region are proposed.
