摘要: 在台风天气应用热扩散技术对福建长汀土壤严重侵蚀区的马尾松树干液流进行测定,结果显示:台风带来的高强度降雨和大风抑制了马尾松的蒸腾作用;台风降雨并未提高植物的可利用水分;台风前后马尾松的光合作用和水分生理活动无明显差异;台风过程中与马尾松树干液流密度极显著相关(P<0.01)的环境因子有太阳辐射、空气温度和水汽压亏缺,晴天时则为空气温度、太阳辐射、相对湿度和水汽压亏缺。研究表明,台风没有增加植物的可利用水分,也未对马尾松的生理活动产生破坏作用。

Abstract: Application of thermal diffusion technology to measure the sap flow of Pinus massoniana in serious soil erosion areas in Changting county during the typhoon, the results showed that:typhoon brought high-intensity rainfall and strong winds which suppressed transpiration;the rainfall didn't improve plant availability moisture;photosynthesis and water physiology before and after the typhoon had no significant difference;the sap flow density during the typhoon was significantly related (P<0.01) with the environmental factors as:solar radiation, air temperature and vapor pressure deficit, while on sunny days were:air temperature, solar radiation, relative humidity and vapor pressure deficit.Studies have shown that:typhoon did not improve the plant available water, nor destroy the physiological activities of Pinus massoniana.

Key words: sap flow, typhoon, Pinus massoniana, serious soil erosion areas
