摘要
沿淮淮北地区年度间土壤含水率差异较大 ,土壤含水率与当年降雨量呈正相关 ,60cm以上土层的含水率相关显著。淮北地区的平均土壤含水率高于沿淮地区。随着土层的加深土壤含水率的变化逐渐变小。淮北地区土壤含水率的垂直分布呈“S”型 。
The content of soil moisture in different years was obviously different and significantly relative with rainfall in Yanhuai and Huaibei Region of Anhui Province. The content of soil moisture was similar trend in Yanhuai and Huaibei region, but the average content of soil moisture in Yanhuai was higher than in Huaibei Region. The content of soil moisture declined slowly with the increase of soil layer depth. The vertical distribution cure of the content of soil moisture was 'S' shape in Huaibei Region.
