The most striking results came from the alley cropping treatment , where the amount of runoff was reduced by 58 % under the low input and 81 % under the high input treatment , when compared to the no input treatment 最明显的结果是巷带种植处理，与不投入相比，低投入情况下径流量减少58 % ，高投入处理减少81 % 。
At the arid area , the volume of water is insufficient and uneven distribution , and the runoff most concentrates in the flood season . reservoir as important water project should utilize the flood adequately 在干旱区水资源量不足,分布不均,河流的径流量主要集中在汛期,水库作为重要的水利工程,存在着洪水资源化的问题。
This paper introduced how to forecast the variation of runoff in the future and estimate the reliability of the water supply source system in operational period , by using the weighted and fuzzy markov ' s chain model 摘要本文通过建立模糊带权马尔柯夫链模型，预测径流量未来的丰枯变化情况，评价运行期供水水源系统的可靠性。
One exception is tu - wei - he catchment where underground runoff is the primary part of river flow . its runoff season distribution is much uniformity . its runoff amount of july to august accounts is 24 % of the annual runoff amount 但以地下径流补给为主的秃尾河，径流量的季节分配相对均匀， 7 8月份径流量占年径流量的24 。
Large - scale changes of landscape structure cause the degradation of functions of storage and drainage in watershed wetland , which are reflected by loss of flood holding capacity , increase of surface runoff and decrease of confluence time etc 景观结构的巨大改变引起了流域湿地贮、排水功能的衰退，主要表现为滞洪、消能空间的丧失，径流量的增加和汇水时间缩短等。
In order to evaluate the surface water budgets of avim and to evaluate the ability to simulate runoff , the implementation of avim to xilinhe drainage basin ( in mongolia ) and daily streamflow simulations from the year 1991 to 1994 are presented 本文在已建立的陆面模式avim中，引入产汇流模型，模拟了内蒙古锡林河流域1991 - 1994年的土壤温湿状况、地表通量和径流量。
