摘要
分析广西凭祥市马尾松松脂产量的年度变化规律及气温和降水量对马尾松松脂产量的影响。结果表明:马尾松松脂产量在一年中呈抛物线变化,在8月产量最高。在个别时间点上略有波动,这可能与当地这段时间气温较低、阴雨天过多、光照时间及强度较低有关。所研究的气象因子对松脂产量影响大小为:气温>日照时数>降水量>相对湿度。各气象因子之间也具有相关性,对松脂产量影响既互相促进又互相抑制。
The yearly fluctuation of main meteorological factors including temperature and precipitation etc, as well as their effects on pine resin yield were investigated in the present study. The results showed that the annual change of pine resin yield characterized in a parabola pattern, whoes ceiling value was obtained around August. Slight fluctuation was observed in some individual time points, which may be ascribed to the low temperature, frequent rain, low illumination. Among the interactional meteorological factors, temperature ranked the first in contribution to pine resin yield, followed by sunshine hours, precipitaion and relative humidity.
