摘要
阐述了森林保持水土的条件 ,即良好的林分结构、必要的面积比例和一定的林龄 ,揭示了成林过程中水土保持功能的动态变化 。
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.
