| 摘 要： | 黄河中游黄土地区一般系指长城以南、秦岭以北、太行山以西、西宁以东地表覆盖有厚层黄土的地区。包括整个黄土高原及南部海拔低于800米的黄土台源及高阶地区。由于这一地区土壤均发育于黄土母质之上,又同属季风区,所以在土壤水分的性质与循环特征上存在很多相似规律性。过去把土壤水分作为一个肥力因素,研究它的状况、移动及其和作物生长

| Abstract: | The loess region lies in the middle reaches of Huung He River. The water-holding capacity, evapotranspiration, water deficit in soil, infiltration of rainfill into soil and the dry layer for soils in the loess region are investigated in this paper and their effect on ecological environment is also discussed.The soils in most of the loess region have a waterholding capacity of 250mm per metre of soil layer. The annual evapotranspiration corresponds approximately to annual average precipitation for the fields... |
