| 摘 要： | 对深圳福田红树林群落两个优势种桐花树（Ａｅｇｉｃｅｒａｓｃｏｒｎｉｃｕｌａｔｕｍ）和秋茄（Ｋａｎｄｅｌｉ－ａｃａｎｄｅｌ）进行横剖树干解析，研究这两个树种的胸径、地径、树高、材积生长量的年变化规律及形数年变化规律，结果为：胸径、地径、树高、材积生长量呈镊合状曲线态；其年生长量一般在其最大值的５０％～９８％之间；各种平均生长量随年龄的增加而平缓地增加，近峰值而未及，可见两树种有相当长的成熟及衰老期，它们的现存年龄为２０ａ左右；两树种的基部形数不随年龄的增加而呈规律性的变化，很难确定其经验形数值

| Abstract: | The mangrove community in Futian Nature Reserve, Shenzhen City, Guangdong province, is dominated by Aegiceras cormiculatum and Kandeha candel . The growth of these twoplant species was invcstigatcd by stem analysis. The mean annual incremcnt and cumulatlive incrcmcnt in tree height, stem basal and breast height diameter of thcsc two species were compared. The cumulative increment in biomass and trcc volumc was larger than that of the mcan annual incrcmcnt. The mean annual increment of these trees increascd with age, towards the peak values. Both species were about 20 years old and had rcachcd thcir mature slatus for some time. |
