| 摘 要： | 研究对象为德州市绿化带内的垂柳、榆树、国槐、刺槐、紫荆、大叶黄杨6种绿化树种。每种选取60片大小不一、发育正常的展开的叶片,以叶长、叶宽、长×宽、面积作为指标,求出叶面积和长×宽的回归方程,各回归方程均呈极显著正相关系,为绿化树木叶面积的测定提供一个简单、可靠的方法。

| Abstract: | Six kinds of broadleaf trees as Salix babylonica Linn.,Ulmus pumila L.,Sophora japonica L.,Robinia pseudoacacia L.,Cercis chinensis Bunge.and Euonymus japonicus L.were studied.Sixty leaves of different sizes with normal growth were seleeted for each kind of trees for greening.A study was conducted to estimate leaf area of the trees for afforestation using regressive equation.The leaf area estimation were found to be significantly correlate to the parameter.There were most significant positive correlations between the leaf area and lenth times width,thus providing a simple and practical method of high reliability for the determination of leaf area of garden kinds of trees. |
