| 摘 要： | 根据冉庄水资源实验站资料,分析土壤水分布特征。实验提出当地下水埋深为2m时,土水势剧烈变化带在0~1.4 m。地下水埋深超过10 m时,土壤水剧烈变化带为0~2.2 m。地下水埋深为8 m时,2 m以下的土壤水资源量仅占全剖面的11.1%,3 m以下的土壤水资源量仅占全剖面的8.1%。本地主要作物为玉米、小麦。玉米最大根深在1.0~1.5 m,小麦最大根深在2.0~2.5 m。综合分析,得到河北省山前平原地下水大埋深区土壤水资源评价层厚度为2.5~3.0 m。

| Abstract: | Based on the data collected by Ranzhuang water resource experimental station, the paper analyzes the distribution characteristics of soil water. When the groundwater is 2m beneath the ground surface, the soil water is localed from 0m to 1. 4m be-neath the ground surface. The soil water distribute from 0m to 2. 2m in depth when the groundwater buried 10m from the ground sur-face, or farther. Especially when the groundwater is 8m beneath the ground surface, the soil water distribute over 2m from ground surface counts 11. 1% of the total soil water, while the soil water distribute over 3m from ground surface counts 8. 1%. The main crops in the studied region are corn, whose root length is from 1m to 1. 5m and wheat whose root length is 2m to 2. 5m. Taking all data into consideration, the paper thinks that the thickness of water resource evaluation layer of soil in the Shanqian plain of Hebei province is from 2. 5m to 3m. |
