摘要
通过有林沟与无林沟测流堰资料的比较分析表明,在观测期有林沟径流量比无林沟减少57.5%,各次洪水过程中洪峰削减率达20%~90%。在雨季森林集水区最明显的特征是增大对后续降水的吸收(截留和入渗)和利用。
Based on a comparison analysis of retention data from measuring weirs in the forestcathment and control unforested catchment,runoff volume in the forest catchment was decreasedbv 57.5% and peak flood was decreased by 20% to 90%in each floOd Drocess as comoared withthe control unforested catchment during the observation period.In rainy season,the most obviouscharacteristics of water conservation in the forest catchment refer to increase in absorbtion(interception and infiltration)and consumption(transpiration)for succeeding rainfall.
