| 中文摘要: |
| ：集雨农业是指收集、存储雨水径流并将其作为农村家庭人畜饮用水、环境卫生用水和农业补充灌溉用水的农业生产活动,包括收集、存储、输送、利用等多个过程,但目前各地的集雨农业技术研究多注重单项技术研究,而没有把它们当作一个整体来进行研究,导致许多地方出现收集与存储、收集与利用、存储与输送、存储与利用等脱节的现象,使各个环节的雨水利用转化效率普遍偏低。本文首先比较系统完整地提出了集雨农业雨水利用转化效率的概念,将集雨农业的雨水收集、雨水存储、雨水输送和雨水利用等各个过程看作一个整体进行研究分析,然后结合有关试验资料提出了提高集雨农业雨水利用转化效率的途径。 |
| 英文摘要: |
| Rainwater harvesting for agriculture is the agricultural activity which collects stores runoff and uses it for drinking sanitation and supplemental irrigation. It includes several interrelated processes ：rainwater collecting rainwater storing rainwater transporting and rainwater utilizing. Prevenient researches of rainwater harvesting focused more on each individual process or technique and did not concern the processes or techniques as a whole. This resulted in a loose relationship of above processes and low water transfor ming efficiency from one process to another. In this paper the concept of Water Using and Transfor ming Efficiency of rainwater harvesting is put for ward systematically. The sub-processes of rainwater harvesting-rainwater collecting rainwater reserving rainwater transporting and rainwater using are studied and analyzed as a whole. Then combining some experi mental data several ways to enhance rainwater using and transfor ming efficiency are provided. |
