| 中文摘要: |
| 测定吉县蔡家川流域不同植被类型土壤的持水性能,通过对土壤水分特征曲线的拟合,掌握不同林分土壤比水容量,并对不同林地的土壤水分进行分类,求出不同林地的有效水范围。在研究区主要造林树种中,刺槐及其混交林分的土壤水分利用范围最大,退耕地有效水分利用潜力最大。 |
| 英文摘要: |
| The characteristics of soil water of different woodlands were studied by the advanced survey methods.The simulation equations of soil water characteristic curve of different stands were set up to calculate the soil specific water capacity,and to determine the range of available water by classifying the soil water in different stands.Among the main plantation species,the range of soil available water of robinia psedoaeacio and its mixed stands is maximal,and the potential capacity of soil available water of returned farmlands is maximal. |
