采用位置指数(CE)、混交指数(DM)、分异指数(T)以及 Ripley’s K-方程,探讨了福田红树林保护区海桑+无瓣海桑自然林的空间结构特征。海桑、无瓣海桑、秋茄和桐花树种群呈现集群分布;海桑-无瓣海桑、海桑-秋茄、海桑-桐花树、桐花树-无瓣海桑以及秋茄-桐花树之间在空间分布上呈现负关联,秋茄-无瓣海桑之间呈现正关联,但都不显著。海桑和秋茄与其它树种属于中度混交,而无瓣海桑和桐花树与其它树种的混交程度较弱。海桑和无瓣海桑之间的胸围差异明显,而其它树种个体之间的胸围差异中等。海桑个体之间的树高差异明显,而其它树种个体之间的树高差异中等。采用空间指数和空间统计技术有效地描述了树种的空间属性。
The spatial structure characteristics of natural forest of Hassang + Mori Sonneratia forest in Futian mangrove protected area were studied by using the index of location (CE), mixed index (DM), differentiation index (T) and Ripley’s K- Hesse, Anemarrhena asperis, Haeinsa - candelilla, Hassang - Aegiceras corniculatum, Aegiceras corniculatus - Anemarrhena asphodelus and Candelia - Tung There was a negative correlation between flower trees in the spatial distribution, but there was a positive correlation between the candel and the non-petal sea mulberry, but both were insignificant. Hesang and candel were moderately mixed with other species, while the non-Hedysarum-mongolicus and Aegiceras corniculatus mixed with other species less well. Busts vary significantly between sea cucumber and non-petal sea moss, while busts differ moderately among other species. The difference in tree height between individuals of the sea cucumber is significant, while the tree height difference among individuals of other species is moderate. Spatial indices and spatial statistics techniques are used to effectively describe the spatial attributes of tree species.
