| Abstract: |
| 【Objective】Soil moisture is a key factor affecting vegetation restoration and reconstruction. In order to know the effects of different artificial vegetation on soil moisture, which provided scientific basis for vegetation restoration and ecological construction.【Method】The soil moisture changes of 0~100cm under 3 different modes of returning farmland to forestland (Hippophae rhamnoides Linn., Caragana korshinskii., Ulmus pumila L.) in Bashang area of northern Hebei were compared and analyzed, by taking the enclosed grassland as the control.【Result】The soil moisture of different artificial vegetation varied significantly with the seasons; in rainy season (June, July, August), the soil water contents of 0~100cm under 3 different modes of returning farmland to forestland were higher than that of the enclosed grassland, which was conducive to soil moisture conservation; in dry season ( May, September, October) it was lower than that of enclosed grassland, which increased soil water consumption. The soil moisture of different artificial vegetations had obvious trend characteristics with the change of soil depth; the water content of 0~20cm soil layer under enclosed grassland was obviously decreased, and the water consumption of 0~40cm soil layer under Hippophae rhamnoides Linn.forestland was obvious, the water consumption of 30~60cm soil layer under Caragana korshinskii.forestland was obvious, and the water content of the 20~100cm soil layer under Ulmus pumila L. forestland was continuously consumed.【Conclusion】It can be seen that the artificial restoration of vegetation in Bashang area of northern Hebei must fully consider the regional precipitation, temperature, soil and other environmental conditions, follow the natural zonal law, and make rational distribution according to local conditions. |
