Research on Soil Water Retaining Capacity of Typical Forests in Jinyun Mountain.

Abstract: The purpose of this paper is to provide a basis for construction of water conservation type of vegetation. In this paper, the forest soil pore distribution and water storage properties of four typical forests (mixed wood, broadleaf forest, bamboo forest and shrub forest) in Jinyun Mountain were compared. The water holding capacity of soil non-capillary of shrub forest is 88.24 millimeter, 83.52 millimeter in mixed wood, 75.96 millimeter in broadleaf forest, and 63.48 millimeter in the bamboo forest. The saturation water capacity of shrub forest is 361.62 millimeter, 323.16 millimeter in mixed wood, 295.62 millimeter in broadleaf forest, and 267.92 millimeter in the bamboo forest. The results indicated that the water holding capacity of soil non-capillary from high to low is shrub forest > mixed wood > broadleaf forest > bamboo forest. The shrub forest and mixed wood have higher water conservation function than the bamboo forest. Therefore, it is proposed that in the future the shrub forest and mixed wood should be afforested and managed firstly. [Copyright &y& Elsevier]
