【摘要】 从林木随机分布的角度对林分密度的调查精度进行了相关分析。分析指出,在天然的林分中,林木分布具有一定的随机性,在一定面积的样地中,林木株数服从泊松分布,并得出结论,林分密度调查精度的直接影响因子为调查的林木株数。更多还原

【Abstract】 The survey accuracy of the stand density was analyzed from angle of trees randomly distribution. The analysis pointed out that,in the natural forest,the forest is the random distribution,in a certain area of the plots,trees can be considered to obey a Poisson distribution,and draws the conclusion,the direct effect factors of stand density survey precision is the number of investigation on trees.更多还原
