安徽淮河流域耐水湿树种的聚类分析及布局研究

１９９２年４至５月，对安徽省淮河流域前一年遭受特大水灾的８个县市树木生长情况进行了调查，并按所调查各县市的树种在受淹１一２月、水淹１一２ｍ和受淹部位达到树干部的存活率，进行聚类分析，将其分别归入极耐水湿、较耐水湿、微耐水湿和不耐水湿４个等级。本文最后对治淮绿化工程耐水湿树种的选择和布局提出了建议。

Cluster Analysis of Water Tolerant Trees of Huaihe River Afea of Anhui Province

Growth statues of trees in 8 counties and cities in Huaihe River Area of Anhui wasinvestigated in April to May ,1992 ,afters a heavy flood in l991.A cluster analysis was conductedbased on the(surviving) rate of trees which were in flood for differlnt time lengths ,in differentflood depths,and with differcnt parts in flood.The trees were rated into 4 classes :the mosttolerant,tolerant, slightly tolerant ,and less tolerant.Suggestions were made on species selectionand distribution of water tolerant tress for afforestation programs along Huaihe River.
