摘　　要：对河南伏牛山区小叶杨(Populus simonii Carr.)的种质资源分布现状及生长规律进行了调查研究。结果表明,伏牛山区小叶杨有2变种和3变型,即秦岭小叶杨(Populus simonii Carr.var.tsinlingensis C.Wang et C.Y.Yu.)、洛宁小叶杨(Populus simonii Carr.var.luoningensis T.B.Zhao.)和塔形小叶杨(Populus simonii Carr.f.fastigiata Schneid.)、垂枝小叶杨(Populus simonii Carr.f.pendula Schneid.)、菱叶小叶杨(Populus simonii Carr.f.rhombifolia(Kitag.)C.Wang et Tung.)。对小叶杨各个变种和变型在不同立地条件下的生长情况进行了调查,并对小叶杨树干进行解析,研究了其生长规律,为小叶杨天然林资源的保护和利用提出了建议。In this paper,the distribution and growth pattern of of Populus simonii Carr. in Henan Province were investigated. The results showed that in the Funiu Mountainous areas there were 2 varieties and 3 forms of Populus simonii Carr. : Populus simonii Carr. var. tsinlingensis C. Wang et C. Y.Yu,Populus simonii Carr. var. luoningensis T. B. Zhao and Populus simonii Carr. f. fastigiata Schneid.,Populus simonii Carr. f. pendula Schneid.,Populus simonii Carr. f. rhombifolia(Kitag.)C. Wang et Tung. The growth of varieties and forms of Populus simonii Carr. in different site conditions were investigated and their trunks were parsed. The growth law of Populus simonii Carr. was studied. and the suggestions were put forward for the protection and utilization of its natural forest resources.
