Forest landscape is an important part of the overall landscape area,studying the spatial distribution pattern of the regional landscape will play important role in optimizing the overall structure and exerting ecological and economic benefits.Based on the data of Lushan 2010 vegetation patches,the study use the method of point pattern analysis to analyzes the spatial distribution pattern of five kinds forest landscape features from the view of different developmental stages and forest landscape forest types,from the perspective of different types of forest landscape,the different.development stage and different forest structure type,introduces the point pattern analysis method in the field of ecology to conduct research on spatial pattern of landscape characteristics and correlation of Lushan forest under the single scale and multi-scale.From the perspective of integral space scale,evergreen broad-leaved forest,deciduous broad-leaved forest,Chinese fir,pine and bamboo landscape scales all obey the rule of whole cluster distribution and different kinds of forest landscape gather together varying from dense to discreteness.And different development stages of the spatial distribution of forest landscape types is given priority to concentration distribution,random distribution is complementary,young forest cluster in the most significant,and mid-maturation forest and mature forest agglomeration strength decreases in turn.From the classification of forest type structure,all natural forest landscape are distributed in clusters,and as for the man-made forest except that the pine and Chinese fir have significant concentration distribution classes while others tend to be randomly distributed.Ripley's L function bivariate analysis multi-scale spatial correlation characteristics of forest landscape,reveals the Lushan mountain forest landscape ecological process.Research has showed that all kinds of forest landscape is given priority to with space positive correlation and the Space unrelated is supplementary.Between young forest and middle-aged forest,the correlation strength is much larger than old-growth forests compared with both of them,which even shows Space unrelated and a negative correlation characteristics,and there is a large difference within different kinds of forests of all kinds of forest landscape.Above all,Lushan mountain forest landscape is still in the developmental stage of infancy,belongs to the typical vegetation recovery,this is because the original vegetation of Lushan has been destructed by human,sapling forest landscape is into a film distribution.Natural forest is still given priority to with strong ability to update the broad-leaved forest,and plantation with planted forest in a large area is treated as focus,so in the future to protect natural forests,there has a long way to facilitate afforestation.The study of Lushan mountain forest landscape spatial pattern characteristics and correlation can provide a theoretical guidance for ecological environment protection and sustainable forest management.
