摘要
2006年秋季,对江西18种常见树种的枝、叶每天进行失水率和含水率的测定,建立了失水率与温度关系的数学模型,分析了树种间、枝和叶间含水率和失水率的差异,研究了失水率与时间的变化关系,并得出了不同树种的枝条失水率稳定在11 d,树叶稳定在8 d。综合含水率和失水率2个指标,认为木荷、马尾松、珊瑚树、鹅掌楸、油茶是较好的防火树种。
Based on the measurement of dehydration rate and humidity rate of 18 common arboreal branches and leaves in Jiangxi, the mathematical model between dehydration rate and temperature has been established, the differences between dehydration rate and humidity rate among trees, branches and leaves have been analyzed and the relationship between dehydration rate and time has been studied. The results show that the dehydration rates of different trees keep to be 11 days while the leaves to be 8 days. Based on the two indexes, the dehydration rate and humidity rate, Schima superba, Pinus massoniana, Viburnum odoratiss, Liriodendron and Camerllia oleifera are good anti-conflagration trees.
