野外模拟降雨条件下高寒草甸区植被退化和人工植被恢复坡面的产流产沙过程
Shuitu Baochi Xuebao[目的] 青藏高原是我国重要生态屏障,高寒草甸是其重要组成部分,水土保持功能是高寒草甸重要生态服务功能。开展青藏高原高寒草甸区水土流失过程研究对减少人为扰动水土流失、保障西南地区生态安全具有重要意义。[方法] 选取青藏高原高寒草甸未退化、轻度退化、中度退化、裸坡与人工植被恢复5种不同类型坡面,通过野外模拟降雨试验,分析不同雨强条件下,不同植被退化与恢复坡面产流产沙过程,揭示植被退化与人工植被恢复坡面土壤侵蚀机理与水沙关系。[结果] (1)高寒草甸未退化坡面与人工植草恢复坡面因其根系较为致密 ...

Applications of image methods for the measurement of granular flows
[[abstract]]顆粒材料的流動包含流體與固體的特性。為了充分瞭解顆粒流的行為，本研究使用粒子追蹤測速法量測實驗中顆粒的速度。 為了提高粒子追蹤測速法的準確度，本研究分析各實驗照片之特性來調整粒子追蹤測速法的參數以及比對方法。主要採取的步驟為，校正所拍攝到之圖片，並且使用影像方法強化顆粒中心與背景之差異。利用此差異取得顆粒中心後，藉由顆粒的幾何形狀與排列方式排除非觀測平面之顆粒。顆粒配對的部份則是使用星形比對為主要概念，本研究透過改變配對星形的分支數目與計算方式，來達到精確的星形比對效果 ...
