【摘要】 借鉴群落生态学种间联结的概念,采用2×2列联表,通过方差检验、2χ检验与联结指数对海南岛东南海岸带风景区的植被景观各类型间的空间关联性进行了定量分析。结果表明,空间关联能有效地分析植被景观类型之间的空间关系。尽管海南岛东南海岸带植被景观各类型之间呈现出正关联,且它们之间的关联很松散,具有很高的独立性,但是人类活动的干扰使得植被的发育与发展与其呈现极其显著的空间相互排斥作用。由于植被斑块破碎,相互交错,空间异质性高,景观要素或者斑块类型表现出十分复杂的空间镶嵌的分布格局。通过景观关联度分析,大体上推断出5种植被景观要素类型之间的总体空间布局关系与规律为:“阔叶林-灌草丛-针叶林-人工林-红树林”。更多还原

【Abstract】 A series of techniques,borrowed from the conception of interspecific association in community ecology,including the test of variance,χ~2 and association index were used together with a 2×2 contingency table in order to analyze the inter-type association of vegetation landscape types in the South-East Coastal Zone of Hainan Island.The results indicated that spatial correlation could be effectively used to analyze spatial relationship among vegetation landscape types.Although all types of vegetation landscapes showed a non-significant pattern of positive correlation,and had high independence,disturbance of human activities caused a very significant rejection between vegetation landscape and human disturbance.Because of fragmentation,intersection and high heterogene of vegetation patches,vegetation landscape showed a very complex and mosaic distribution pattern.By means of spatial correlation analysis,the whole distribution outline of five vegetation landscape element types was deduced as follows:broad-leaved forest-scrub and herbosa-evergreen coniferous forest-human-plantied forest-mangrove.更多还原
