| 摘 要： | 为了探讨2种红树植物叶片对生活污水环境的适应性，采用石蜡切片法和显微拍照法观察了白骨壤和红海榄2种红树植物的叶片结构。结果表明：污染区的白骨壤叶片的上角质层厚度、表皮层厚度、上内皮层厚度等均比无污染区的白骨壤大，而污染区的红海榄叶片则在下角质层厚度、上表皮层厚度、下内皮层厚度等指标上比污染区的红海榄显著增大，表明生活污水对红树植物的生长有一定的影响。

| Abstract: | The leaves of Avicennia marina and Rhizophora stylosa were observed using the ‘paraffin method’ and also an optical microscope, to evaluate the potential adaptability of these two mangrove species to tolerate waters polluted with domestic sewage. The results showed that leaves of A. marina and R. stylosa growing in polluted areas had thicker uper cuticles, epidermis and uper endodermis compared to those growing in unpolluted waters, though the lower cuticles, uper epidermis and lower endodermis of R. stylosa in polluted areas were also significantly thicker. Consequently, domestic sewage can have significant effects on mangrove plants growing in waters that have been polluted by it. |
