Studies on forest water cycling

Abstract

Principal ideas, research approaches and installations in both Liangshui and Maoershan Ecological Stations were discussed. Significance of comparability and synchronous determination in research methods were stressed. Comparison analysis was done on the results gained from different methods. Adaptive mechanisms of Mongolian oak (Quercus mongolica) to drought and unproductive sites were expounded through hydrological cycling studies. Surface runoff and flood peak were decreased and the developing processes of flood peak were postponed or delayed because of the presence of huge forest canopy and forest floor. However, the conclusions of forest influences on total runoff, especially in spring and in the dry season t are significant to agricultural practices in northeast China and turned out contrary for watershed sizes or different approaches, which should be studied further.
