- 摘要:
- 应用TDP技术在干旱少雨的6月与雨季9月，对大青山奎素试验区30 a生油松人工林树干液流变化特征及其与主要气象因子的关系进行了研究。结果表明：（1）液流量日变化呈现“昼高夜低”典型的液流波形特征。（2） 油松单株液流量日平均值9月大于6月，表现出雨季液流量大于干旱季节的特征。（3）油松整株树干径向不同位点的液流速率变化趋势基本相同，平均液流速率由外向内呈现“低－高－低”的态势。（4）树干液流量与主要气象因子相关分析表明，对于林分密度较小的林地，6月、9月液流量与太阳辐射有极显著的正相关关系，与20 cm土壤温度有极显著的负相关关系，与气温和相对湿度相关性不高；而对于林分密度较大的林地，在较干旱的6月，太阳辐射已不是影响液流量的主要因子，只有9月液流量与太阳辐射有极显著的正相关关系，与20 cm土壤温度有极显著的负相关关系。
- Abstract:
- The stem sap flow characteristics and the relation with meteorological factors of 30 a Pinus tabulaeformis were researched by using TDP method in Kuisu forest farms of Daqing Mountain. The results indicated: (1) the diurnal variation of sap flow displayed a typical wave form characteristic. The sap flow flux in daytime was higher than that in nighttime. (2) Average sap flow flux of individual plant in September was higher than that in June. (3) The sap flow velocity variation in sun side at different radial depths of Pinus tabulaeformis stem had similar trend. And average sap flow velocity from exterior to interior showed the rule which was lower-higher-lower. (4) The results of correlation analysis of sap flow flux and the main meteorological factors indicated that different stand densities had different rules. For the lower density stand, there was a significant positive correlation between sap flow flux and the solar radiation. And there was a significant negative correlation between sap flow flux and soil temperature at 20 cm depth. The sap flow flux didn’t have obviously interrelated with air temperature and relative humidity. While for the higher density stand, in arid June the solar radiation wasn’t the dominant influence factor. In September there was a significant positive correlation between sap flow flux and the solar radiation, and a significant negative correlation between sap flow flux and soil temperature at 20 cm depth.
