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。
Loess Plateau Soil Erosion and Dryland Agriculture State Key Laboratory of Soil Erosion Simulation Experiment Hall since its completion in 1992 has been operating normally, in the rainfall area is large, wide range of rainfall intensity adjustment, rainfall and natural rainfall close to the degree of automation and control Degree, etc., are currently the most in the country. In the experimental study of soil erosion has played an important role. Based on the significance of soil erosion simulation experiment, the design basis, selection, installation and installation of simulated rainfall devices (including rainfall showerhead, water supply network, etc.) are briefly introduced. The basic characteristics of simulated rainfall are introduced.
