摘要
采用空间自相关分析探讨了我国红树植物的分布规律。对 2 1个红树植物分布地点的分析表明 ,各地具有的红树植物总数存在显著的正空间自相关 ,Moran‘sI指数为 0 .5144±0 .1830。根据不同红树植物空间自相关情况 ,可以将红树植物的分布划分为 5种类型 ,均有效地反映了红树植物的分布特点。分析表明 ,自然状况下 ,红树植物的分布格局主要是由于环境因素、迁移和隔离障碍决定的 ,但人类活动的影响越来越重要。
Distribution of the mangroves at 21 localities in China was studied by using spatial autocorrelation analysis. Results showed that the numbers of mangrove species at the 21 localities were positively autocorrelated. The index of Moran`s I was 0.5144±0.1830. Five distributional types of mangrove were obtained according to the spatial autocorrelation of each mangrove species using nominal data. The classification of the distribution types reflected the actual spatial patterns of mangroves. The spatial pattern of mangrove species was affected by environmental conditions, migration and isolation barriers, naturally. Nowaday, human`s interference plays an increasing role in the distribution of mangrove.
