Spatial Correlation among Vegetation Landscapes in South-East Coastal Zone,Hainan Island

A series of techniques,borrowed from the conception ot interspecific associa- tion in community ecology,including the test of variance,x_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 re- suits indicated that spatial correlation could be effectively used to analyze spatial relation- ship among vegetation landscape types.Although all types of vegetation landscapes showed a non-significant pattern of positive correlation,and had high independence,dis- turbance of human activities caused a very significant rejection between vegetation land- scape and human disturbance.Because of fragmentation,intersection and high heterogene of vegetation patches,vegetation landscape showed a very complex and mosaic distribu- tion 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.
