摘要
在开展雨水高效利用的试验研究中 ,用人工模拟降雨的方法 ,可以缩短试验周期 ,加速雨水入渗规律、土壤侵蚀规律的研究进程。可以通过控制试验条件 ,模拟不同环境 ,弥补在自然降雨条件下 ,因环境变化而无法得到试验期内计划的研究结果 ,或者进一步补充论证在自然降雨情况下得到的研究结果。介绍了在水土保持和降雨入渗研究中模拟降雨装置的研究概况 ,提出了简易模拟降雨装置的主要技术参数。
Using the method of artificial simulation of rainfall can shorten the time length of experiment, and speed up the research process of rainfall infiltration rule, soil erosion rule in the experimental research on rain water high_efficiency use. Through control of experiment condition, simulation of rainfall under different environments can be realized. Thus, this method can remedy the failure of experiment of natural rainfall condition due to variation of environment, and validate the experiment result under natural rainfall condition. The present situation of research on soil and water conservation and rainfall infiltration is summarized, and the main technical parameters for the simple simulation device of rainfall simulation are proposed.
