Study on the Hydrology Dynamics of Needle-broad Leaved Mixed Plantation and Evergreen Broad-leaved Forest in Dagangshan

  • Received Date: 2001-08-22
  • This paper, based on methods of experiment technique and the data of collected from observation, the forest hydrology monthly dynamics of artificial mixed stands of coniferous and broad leaved trees and nature stands of evergreen broad leaved trees in Dagangshan district were studied, including soil moisture, surface runoff and total runoff. Some analysis results are as follows: (1)The maximum of soil moisture(5.18 mm) of artificial mixed stands of coniferous and broad leaved trees occurred in May, the minimum occurred in March; the distribute change of moisture in the depth is not obviously. (2)The surface runoff monthly change is greatly, and one off rainfall obviously affects soil moisture (R2 =0.939 5). (3)Compared with artificial mixed stands of coniferous and broad leaved trees, nature stands of evergreen broad leved trees had good effect of prevention of water and soil erosion and function of water conservation.

Abstract: This paper, based on methods of experiment technique and the data of collected from observation, the forest hydrology monthly dynamics of artificial mixed stands of coniferous and broad leaved trees and nature stands of evergreen broad leaved trees in Dagangshan district were studied, including soil moisture, surface runoff and total runoff. Some analysis results are as follows: (1)The maximum of soil moisture(5.18 mm) of artificial mixed stands of coniferous and broad leaved trees occurred in May, the minimum occurred in March; the distribute change of moisture in the depth is not obviously. (2)The surface runoff monthly change is greatly, and one off rainfall obviously affects soil moisture (R2 =0.939 5). (3)Compared with artificial mixed stands of coniferous and broad leaved trees, nature stands of evergreen broad leved trees had good effect of prevention of water and soil erosion and function of water conservation.
