- Title:
- Study on Spring Soil Moisture in Loessial Gully Hill Area of West Shanxi Province

- 摘要:
- 采用固定点动态监测的方法，对黄土丘陵区方山县峪口镇花果山人工植被恢复过程中春季土壤水分动态变化进行了研究。结果表明：5月份土壤含水量有较大的升高；荒草坡土壤水分条件最好，针叶林、经济林土壤水分条件较好，柠条灌丛土壤水分条件一般，刺槐纯林土壤水分条件最差；土壤水分阴坡好于阳坡；土壤水分随林分密度的变化规律较为明显，黄土区造林密度不宜过大或过小，以适应有限的土壤水分资源。测点剖面不同部位土壤水分含量差异较大，形成剖面土壤水分总体上高下低的分布规律；各样地表层土壤水分的变异程度最大，而后不断减小至基本保持不变。
- Abstract:
- Using fixed-point dynamic monitoring methods, soil water was studied during the process of cultivated vegetation succession on the Huaguo mountain area in spring. The results showed that: The soil moisture increased significantly in May. The soil moisture in slope grassland was the best. Coniferous forest and economic forest soil moisture conditions were better. Caragana shrub soil moisture conditions was in general, Robinia pseudoacacia was the worst of all. The coefficient can reflect a law that the soil moisture in north-slope was better than that in south-slope. The change of soil moisture in different vegetation density was obvious. The vegetation density was moderate in the Loess Gully Hill Area. The soil moisture content of different depths was different. The surface was better than the bottom. The variability of surface soil moisture was the greatest, and then decreases, and to essentially unchanged.
