摘要
南方红豆杉（Ｔａｘｕｓｃｈｉｎｅｎｓｉｓｖａｒ．ｍａｉｒｅｉ）是红豆杉科红豆杉属植物、林业部确定的国家一级保护树种，木材材质优良，更因其含高效抗癌药物紫杉醇（ｔａｘｏｌ）而备受关注。南方红豆杉自然分布于华东、中南、西南以及陕西、甘肃的南部、台湾等地。...
Based on the 2×2 contingency table and different
indices,the relationships among the populations of Taxus chinensis var. mairei community
on the Yuanbaoshan Mountain of China were investigated. The interconnections were described
with the diagrams of semimatricy and constellations. The results showed that there was slightly
positive correlation among the main tree populations from an overall point of view. The W-test
indicated this correlation was not significant. The most pairs of the tree populations in the
community showed either positive or negative correlations. The X 2-test indicated there was
almost no significance in the interspecific correlation. The interconnections were also
theoreticaly analysed in the present paper.
