The spatiotemporal responses of Populus euphratica to global warming in Chinese oases between 1960 and 2015
Populus euphratica annual growing season global warming responses to climate change Chinese oases
2018/4/9
Daily average temperature data from 48 meteorological stations in Chinese oases that are within the distribution area of Populus euphratica were analyzed to determine the spatiotemporal responses of t...
杜加依林建群种胡杨(Populus euphratica)的水分再分配现象已被广泛认知,但该现象对其伴生种多样性和生态位宽度的影响仍不清楚。基于120个样方的调查数据,通过分析比较2010年6、8、10月胡杨林冠下(林冠群落)与非胡杨林下(对照群落)在群落数量特征、物种多样性和生态位宽度上的差别,以探明水分再分配和物种多样性间的关系。结果表明:(1)林冠灌木和草本群落的郁闭度、株高和多度在6、8、...
胡杨(Populus euphratica)蒸腾耗水对小降雨事件的响应
小降雨事件 蒸腾耗水 胡杨 荒漠河岸林
2018/4/18
利用内蒙古额济纳旗1960——2010年逐日降水量观测资料,并连续监测了2012——2013年胡杨蒸腾速率和实时降水量,研究了小降雨事件对荒漠河岸林胡杨蒸腾耗水的影响。结果表明:50年来额济纳旗小降雨事件占总降雨事件的比例达90.63%。不同量级的小降雨事件对蒸腾速率的影响存在较大差异,小于1 mm的降雨发生前蒸腾速率处于下降趋势,降雨发生后蒸腾速率的下降幅度变小,2 h后开始缓慢上升;1~4 m...
