| Abstract: |
| 【Objective】 The purpose of this paper is to explore the spatial and temporal distribution characteristics of soil moisture of seabuckthorn plantation in coal mine reclamation area,and promote water management in the process of artificial forest cultivation. 【Method】 The seabuckthorn plantation in the coal reclamation area of ??Ordos City was studied and different forests were carried out. Temporal and spatial distribution characteristics of soil moisture of Chinese seabuckthorn and Hippophae rhamnoides Linn. plantations.【Result】①With the increase of forest age, the soil moisture of difference Chinese seabuckthorn and Hippophae rhamnoides L. forests showed a trend of “reducing-increasing-decreasing”; the soil moisture of Chinese seabuckthorn and Hippophae rhamnoides L. forests in different forest ages was significant (P<0.05). The soil moisture of Chinese seabuckthorn forest in 6 years old forest was significantly higher than that in other forest age forests (P<0.05). The soil moisture of seabuckthorn forest in 3 years old forest was significantly higher than other forest ages (P<0.05). ②In the 0~100 cm soil layer, the soil moisture difference between the soil layers of Chinese seabuckthorn at 6 years old was not significant, and the soil moisture of the other forest ages of Chinese seabuckthorn and seabuckthorn forest was significant (P<0.05). ③The soil moisture of Chinese seabuckthorn forest increased with the distance from the trunk. The soil moisture of the seabuckthorn forest increased with the distance from the trunk. 【Conclusion】 The soil moisture of seabuckthorn forest land in the reclaimed area of coal mine is quite different. It is necessary to adopt appropriate water management measures according to the specific forest age, tree species and soil space. |
