摘要
红海榄为花、果、植株为一体的胎生植物,开展花的空间分布格局研究,对红海榄的更生繁殖和群落稳定、演替、恢复有重要的意义。本文采用8种聚集度指标(I、C、M*、Ca、K、m、M*/m、S^2)分析了湛江高桥红海榄群落花朵在树冠空间上、中、下等不同冠层,东、南、西、北等不同方位分布,结果表明:高桥红海榄花朵主要分布在上层树冠和南、北两个方位。红海榄花在各个冠层和各个方位的空间分布格局皆为聚集分布。因此,湛江高桥红海榄花的空间分布格局为聚集分布。
The flowers, fruits, plants as the one overall viviparous plant of Rhizophora stylosa. The research of spatial distribution patterns of Rhizophora stylosa flowers has an important role on the Rhizophora stylosa of stable community, rehabilitation and Succession, restoration. In the vestigate,it through distribution comparison and 8 aggregation degree indicates（I. C. M＊. Ca. K. m. M＊/m. S2） to analyse flowers in different crown, different position. Results indicated that Rhizophora stylosa flowers of inner tide in Gaoqiao mainly distributes in upper crown, south position and north position; and has significance difference distribution. The flowers distribution generally belongs to the aggregated distribution pattern of three crowns and four position. So, the Spatial distribution patterns ofRhizophora stylosa flowers is aggregated.
