| 摘 要： | 以章古台地区樟子松人工固沙林为研究对象,开展樟子松蒸腾特性与耗水量研究,研究结果表明:樟子松蒸腾日进程呈双峰曲线变化,并存在蒸腾午休现象;生长季内蒸腾强度大体呈单峰状变化,5、6、9月份较弱,7、8月份最强,最大值出现在7月,为0.677g.g-1FW.h-1;环境因子与蒸腾强度Y按相关紧密程度排序分别为光照X1、土壤含水率X5和空气相对湿度X3,通过逐步回归分析建立回归方程为:Y=0.271 X1+0.007 X3+0.063 X5-0.95;通过分析估算,确定密度为1420株.hm-2的26 a樟子松人工固沙林年耗水量约为0.596万t.hm-2。

| Abstract: | This study investigates the transpiration characteristics and water consumption of man-planted pinus sylvestris var.mongolica in sand at Zhanggutai area.The results show that the daily transpiration of the tree follows a double-peak curve with a 'noon break'.However,the growing seasonal transpiration roughly follows a single-peak curve,low in May,June,and September,high in July and August,with a maximum transpiration of 0.677 g.g-1FW.h-1 in July.The main meteorological factors effecting transpiration streng... |
