淮北平原砂姜黑土区涝渍兼治的组合排水形式

淮北平原地处我国南北过渡带，是我国涝渍灾害严重的典型区域之一。针对涝渍灾害在时间和空间上的相随性和连续性的特点，在本区进行的综合防御涝渍灾害的组合排水技术采用了统筹防御，连续控制的综合措施，实行涝渍兼治。经过二年的试验研究，提出了明沟与暗管、沟井洞、地下排灌、工程与生物措施等适宜于本区的组合排水形式，可因地制宜选择。

Combinative drainage patterns for treating water logging in Shajong Black Soil Area in Huibei Plain

Huibei Plain is one of several areas affected severely by water logging disaster in China. In comprehensive consideration of the effects of reducing water logging damages, raising crop yields and improving economic benefit, experimental results in two years indicate that surface furrow+subsurface pipe, furrows+well+small channel, subsurface drainage and irrigation, engineering measures+biological measures are suitable drainage patterns in shajong black soil area in Huibei Plain.
