摘要:
在前人野外工作的基础上，用“相对生长测定法”对鼎湖山优势种马尾松的树木年轮数据进行处理，获得了1953－1991年鼎湖山马尾松种群的生产力，结合当地的气象数据，用MICROSOFT EXCEL程序对气温与鼎湖山马尾松种群生产力变化的相关性做了一些初步的分析，结果表明：1953－1991年间，鼎湖山当地气温升高了0.6℃，马性松种群生产力增加了3.31 t hm-2a-1。因此，气温波动与马尾松种群生产力的变化有较大的相关性。
Abstract:
Based on the data of Pinus massoniana tree ring in Dinghushan Nature Reserve，Guangdong Province， the productivity of Pinus massoniana population from 1953 to 1991 was obtained using allometric method．The correlation between the changes in local temperature and the productivity of the population was analyzed by MICROSOFT EXCEL program utiIizing meteorological data． The result showed that the productivity increascd by 3.31 t hm-2a-1 with air temperature increase of every 0.6℃.
