本文就易涝地区土壤水分状况的形成规律和特性作了初步的探讨,指出降雨分布的年际和年内的不平衡性和地表迳流来水和去水的不平衡性,是形成土壤水分过多的主要原因,人为措施可以影响土壤水分状况,并提出蓄排结合、全面规划、机械排水、地下粗砂层蓄水、围堤治涝和农业措施等调节措施。
In this paper, the formation regularity and characteristics of soil moisture status in the area prone to flooding are preliminarily discussed. It is pointed out that the annual and annual imbalances of rainfall distribution and the imbalance between incoming and outgoing water from the surface runoff are the causes of soil moisture The main reason for this is that man-made measures can affect the soil moisture status and propose adjustment measures such as combination of storage and discharge, comprehensive planning, mechanical drainage, underground grit reservoir, embankment waterlogging and agricultural measures.
