茂兰喀斯特山地华南五针松邻体干优强度研究

A study of neighborhood interference intensity of pinus kwangtungensis in maolan karst mountain forest

用邻体截光率和邻体干扰指数模型I =∑Ni =1 Si·S-1·di-1,对与贵州茂兰喀斯特山地原始森林中华南五针松个体生长行为之间关系进行研究探讨。结果表明 :华南五针松个体生长速度和个体大小均与邻体截光率和邻体干扰指数呈显著负相关 。

The growth of Pinus Kwangtungensis has been studied by using the way of neighborhood light interception ratio and its interference index model(I=∑Ni=1S i·S -1 ·d i -1 ) in Maolan karst virgin mountain forest. The results show that the growth rate and individual size of Pinus Kwangtungensis are passively correlated with light intercepted ratio and neighborhood interference index greatly. Therefore, it discoveres that neighborhood interference index and its light intercepted ratio affect the growth of Pinus Kwangtungensis obviously.
