摘要
１９９４年，在罗平县八大河乡１９９１年营造的杉木人工林中采集了９块标准地土壤样品，采用灰色关联分析方法，进行土壤肥力研究。根据土壤化学性质对杉木生长影响的大小，计算出各肥力指标的权重，并求得它们的关联度。结果与杉木的树高、胸径生长情况基本吻合。
Applying grey correlation analysis,soil fertility of Chinese fir plantation in Badahe village of Luoping county was studied by collecting soil samples from 9 sample plots.Based on the effect of soil chemical property on the growth of Chinese fir,the weight of every fertility index and the correlation between soil chemical property and the growth of Cheinese fir were calculated.The results of analysis was basically tallied with the tree height and diameter at breast height growth of Chinese fir.
