STUDY ON THE LARIX PRINCIPIS - RUPPRECHTII MAYR PLANTATIONS DIAMETER DISTRIBUTION IN DAQINGSHAN
摘要
Abstract
This paper studied diameter distribution regularities of 32 sample plots of Larix principis rupprechtii Mayr plantation in Inner Mongolia Daqingshan, based on 3 probability density function: normal distribution, weibull distribution and β distribution. The study shows that the fitting effect of diameter distribution of Inner Mongolia Daqingshan Larix principis rupprechtii Mayr plantation with β distribution is better than the other two. Prediction of β distribution function is setted up on the basis,and forecast stand diameter distribution in theory. It provides theoretical basis for scientific management of Larix principis rupprechtii Mayr plantation.关键词
