Study on Soil Water Ecological Environment of Artificial Caragana Korshinskii Bushwood
Wang Mengben Li Hongjian
The analyse result shows that in the artificial Caragana korshinskii bushwood the use ratio of usable soil water is very high; the formation of soil dry season and soil damp season and their water dynamic characteristics are mainly related with the phenophases of Caragana korshinskii and the rainfall of the relevant period of time; and it is a main feature of the vertical change of soil water that there is a obvious decrease in water content of soil deep layer under 120 cm. Though serious water deficit in soil does exert the harmful effect on the productivity of the bushwood, it does not cause the bushwood to die. Because the ratio of infiltration of rainfall into soil is quite large, the bushwood can prevent erosion effectively. Planting Caragana korshinskii bushwood is mainly aimed at giving full play to its good ecological role.
