应用模糊相似比作马尾松优良种源推广的适合度分析

An analysis on adaptability of Pinus massoniana superior provenances using priority ratio of fuzzy equiform.

应用欧氏距离模糊相似优先比分析外省马尾松３个优良种源在浙江省各地区的推广适合度。取水分、热量和高、径生长量等９个相似因子，以原产地为固定样品比较省内５个试验点的适合度。分析结果与１０年生试验林生庆观测结果基本吻合，贵港种源主要适于浙中、浙西地区，龙胜种源主要适于浙东、浙中地区，常宁种源主要适于浙中、浙南地区。

Using priority ratio of fuzzy equihrm of Eu-clidean distance,three masson pine superior provenances were studied on their extension adaptability in Zhejiang Province.some ecological factors, including water and heat quantity,and height & diameter growths of those provenance offsprings were selected as equiform factors,three seed sou rces were used as fixed sample to compare those and the climatic factors,growths of every site in Zhejiang,The analysis results coin-cided with field measures of ten-year-old provenance trial stand,that the seed source of Guigang of Guangxi County mainly suits central and western regions of Zhejiang,that of Longshen of Guangxi mainly suits eastern and central regions of Zhejiang,and that of Changning of Hunan Province mainly suits central, and southern regions of Zhejiang.
