【Abstract】 Conditions for forest to conserve soil and water are elaborated,which include fine stand structure,appropriate proportion of its area,and proper stand age,thus revealing the dynamic changes in the function of the forest to conserve soil and water in the process of its establishment.The results of the study can,therefore, be used as a theoretical basis for developing comprehensive complex techniques for protection forests to sustain their functions to conserve soil and water.更多还原
