摘要
黄土高原土壤侵蚀与旱地农业国家重点实验室土壤侵蚀模拟实验大厅自 1 992年竣工以来运转正常 ,在降雨面积之大、降雨强度调节范围之宽、降雨特性与天然降雨之接近程度、以及自动化控制程度等方面 ,目前均为全国之最。在土壤侵蚀实验研究中发挥了重要作用。在论述土壤侵蚀模拟实验重要意义的基础上 ,简要介绍了有关模拟降雨装置 (包括降雨喷头、供水管网等 )的设计依据、选型和布设安装等情况 ,并介绍了模拟降雨的基本特征。
The rainfall installation of simulated soil erosion experiment hall has been running well since it was fini shed in 1992. It is the best on the areas of adjusting range of rainfall intensity, the consistent degree of raindrop characteristics between artificial and natural rainfall, and degree of automatically controlling etc., thus play an important role in soil erosion experiment research. Based on the important meaning of simulated soil erosion experiment, the design evidence about some installations (including rainfall spray nozzle, water supply pipe net etc.), installation selection, and arrangement etc. is introduced briefly. Meanwhile, the basic characteristics of simulated rainfall are also explained.
