- Abstract:
-
The located observation on soil moisture dynamics and analysis the characteristics of water consumption rhythm under three kinds of vegetations in five years show that annual water consumption of nature forestry, maize and apple tree are 487.8 mm, 519.65 mm and 540.7 mm respectively. Analyzing the water accumulating capacity under three kinds of vegetation showed that the nature forestry of shaded hillside grew in the condition of sufficient soil moisture and every annual water requirement is steady with about 500 mm. Apple tree and maize grew in the condition of shortage soil moisture in the almost every month, which difference of annual water requirement is very large, the variation of water accumulating capacity the nature forestry and maize are 240 mm and 140.7 mm respectively. The crop growing of shortage soil moisture, the annual water consumption is small. The relationship between annual water consumption and rainfall is not significant. But the relationship between annual water consumption and rainfall distribution is closer.
