摘 要：
依据森林资源连续清查获得的云南松天然林样地调查数据及气象数据,研究了年均温、年均降水量与云南松天然林平均胸径生长率的关系.结果表明,不同年均温区域云南松天然林样木平均胸径生长率总体上呈现出温度越高生长率越大的趋势,但趋势在年均温为16℃时出现了拐点,当年均温>16℃时,随着年均温的升高,云南松天然林生长率反而开始降低.在不同降水量区域的云南松天然林平均胸径生长率总体上与年均降水量呈正相关,降水量越大,生长越快.但在降水量为900~1099 mm区域,6~16径阶云南松天然林的生长率却超过了降水量≥1100 mm区域.文中对上述现象进行了讨论,认为其原因涉及云南松的适生区、生态稳定性以及林木的生物学与生态学机制等.

摘 要：
The relationship between average annual temperature, average annual precipitation and average DBH growth rate of Pinus yunnanensis natural forest was studied based on the meteorological data and samples investigation data of Pinus yunnanensis natural forest in continuous forest inventory. The results showed that the average DBH growth rate of Pinus yunnanensis increased with the increment of temperature but presented the decreased trend when the average temperature was above 16℃. The average DBH growth rate increased with the increment of precipitation, which presented the positive correlation with the average annual precipitation. However, in areas with precipitation of 900 ～ 1 099 mm, the growth rate of Pinus yunnanensis with diameter of 6～16 exceeded that in areas with precipitation of 1 100 mm. This paper analyzed that the suitable distribution area of Pinus yunnanensis, the ecological stability and the biological and ecological mechanism were the main reasons.
