| 6. | Abstract : according to the base flow separation results from hydrographs in many watershed , the best regression equation expressing the relationship between annual precipitation infiltration coefficient and the weight of different strata area to total area of the watershed is established . the equation can be used to calculate the precipitation infiltration recharge for different ground water basins in which the strata distribution and the precipitation are given . the precipitation recharge is equivalent to the ground water recharge in some mountainous area where the exploitation of ground water resources are far from being sufficient 文摘:降水入渗补给系数与地层相关分析的目的,是为推求山丘区降水入渗补给量.鲁中山丘区是由各种不同地层出露组成的山丘区域.在多个水文流域基流分割基础上,建立流域年均降水入渗补给系数与各种地层出露面积占流域总面积权重间的最佳回归方程,利用该回归方程和地层分布及降水量推算不同地下水流域的降水入渗补给量.在地下水开发利用不高的山丘区,降水入渗补给量即为地下水补给量 |
| 7. | With the global scarcity of water resources and the birth of rainwater resources , more and more people become to accept the fact that the research of rainwater - collection - storage - utilization ( rcsu ) has been a new growing branch of the water resources subject . recently in many areas , especially in some hilly areas , rainwater utilization has been an effective measure to compensate for water shortage and improve people ' s living standards 随着雨水资源化的诞生,其不可替代的开发利用潜力已被越来越多的人们所接受,已成为水资源科学中的一个新的生长点,特别是在丘陵山区,雨水利用已成为缓解当地水资源紧缺、加快山丘区群众早日脱贫致富奔小康的有效措施。 |
| 8. | It can not only meet the need of water saving , water holding , drought resistance , but also make the best use of local rainfall runoff and efficiently reduce soil erosion . the research on it ' s theory and appliance will promote the development of orchard water saving irrigation and ecosystem and project of soil and water conservation 蓄水坑灌法是一种适合于我国北方山丘区的果林灌溉新方法,既可满足节水、保水、抗旱的要求又能充分利用当地降雨径流和有效控制水土流失。对该方法进行理论和应用研究将对我国北方地区果林节水灌溉和水土保持与生态建设起到积极的促进作用。 |
