沙丘床形之三維多顆粒泥砂躍移研究(II)

, 2006
以往研究的成果，主要是針對二維泥砂顆粒與平底床顆粒的碰撞行為以及泥砂顆粒的運動型態作探討（Garcia and Nino(1994,1998)、陳彥旭(1998)、游景雲(1999)），已獲得不錯之成果。在有關三維泥砂運行與躍移之研究，本研究群（林穎典(2000)、李博甯(2001)、王筱雯(2002)），均假設底床為規則顆粒組成之平坦床形，建立一包含底床碰撞與空間碰撞之三維多顆粒連續躍移數值模式，藉此模式探討顆粒躍移之運動特性。然 而一般明渠中，底床床型會依流速的不同而呈現包括平整(flat bed)、

自然降雨下紫色土坡耕地碳源添加对碳迁移及固碳的影响机制

Shuitu Baochi Xuebao
目的紫色土土壤退化形势严峻，水体流失严重，土壤增碳固碳困难，为探究碳源添加对紫色土坡耕地碳固存的影响。方法以四川紫色土坡耕地为对象，在10°紫色土坡耕地设置不施肥(CK)、化肥+秸秆还田(T1)、化肥+秸秆生物炭(T2)、化肥+牛粪(T3)、化肥+有机改土基质(T4)、化肥+生物炭牛粪菇渣堆肥(T5)6种处理，每种处理重复3次。分析降雨量及不同碳源处理下径流、泥沙、碳质量分数的变化特征。结果1) 降雨量＞30 mm，短时强降雨(16.1 mm/h)可促使地表径流的产出。碳源添加可显著减少地表径流量(p ...
