摘　　要：采用印迹制片法和成像系统,研究校园绿化植物叶片气孔大小、密度、气孔指数及形态特征,结果表明:同一科内不同植物的气孔密度差异不是太大,仅个别存在明显差异。蔷薇科植物气孔密度在(117.812-360.449)个/mm2之间,其中,月季气孔密度最小,石楠气孔密度最大;木犀科植物气孔密度在(165.498-730.715)个/mm2之间。实验中的几种植物叶片气孔密度变化范围较大,可能是因为植物生长环境因素或营养因素造成。实验中各植物气孔的大小长度集中在(20-30)微米之间,各科之间变动范围不大,仅印度橡皮树这一热带移植植物气孔较大,在50微米左右。With the method of print production and the system of microscopic imaging , green plants stomata in one university were investigated from four important parameters, such as pore size, pore density, stomata index and morphological characteristics. The result indicates that the difference of stomata density between different plants for the same family is not too great , and it only exists in very few individuals.The stomata density of Rosaceae plants is between （117.812-360.449）/mm2, among which the minimum is rose and the maximum is photinia serrulata.The stomatal density of Oleaceae plants is between （165.498 -730. 715）/mm2 .The variation range of several plants in the experiment is large .According to analysis it may be due to growing envi-ronment factors or nutritional factors, and it may also be due to some errors caused by sampling differences.The stomata size in the experiment is mostly distributed in the range between 20-30 micrometers.The range between families is not big .Only the stoma of experimental India rubber trees in tropical transplants is large, about 50 micrometers.
