Study On Fire Disturbance Of Taiga And Tree Species Diversity Denoting Of Forest Scenery Aesthetic Quality In Kanas, Xinjiang

Natural fire disturbance, one of the most important disturbance factors in taiga forests, plays asignificant role in formation and maintenance of forest community structure of tree species and forestscenery aesthetic quality. On the basis of the hypothesis, this project regarding famous virgin taigaecosystem in Kanas National Nature Reserve as research objection, taking natural fire disturbance, forestcommunity structure of tree species and forest scenery aesthetic quality as an integral component, mainlystudies effect of natural fire disturbance on forest community structure of tree species, and explores theformation regime of forest scenery aesthetic quality based on the temporal and spatial dynamic responseof forest structure of tree species to fire disturbance. The main results show:There is distinctly different between stand with natural fire disturbance and stand without naturalfire disturbance as for structures of tree species in Kanas. Forest seasonal structure and tree compositionstructure are markedly affected by natural fire disturbance. And the indexes of structures of tree speciesare higher in disturbance plot than ones in stand without disturbance in Kanas. What is more, proportionof tree species and species richness of tree have obvious variance to different period fire disturbances, butthey have not significant difference to different fire disturbance severity. Fire disturbance is one of themain factors which control the structures of tree species.In Kanas, natural fire disturbance controls formation of forest scenery structure and affects thescenic beauty of forest scenery value. The scenic beauty of forest scenery value in Kanas is universallyhigher. However, people prefer the forest scenerys with richer tree species and orderly storey. And theseforest scenerys represent higher aesthetic value.There is a close relationship between forest scenery visual quality and the occurring time of naturalfire disturbance. The forest scenery which is impacted by the early natural fire disturbance has loweraesthetic value, vice versa. It also can be confirmed by radial basis function. Fire disturbance is one ofthe main factors which influence the forest scenery visual quality by controlling the formation ofstructures of tree species. In sum, in the process of forest succession, natural fire disturbance is useful toembodiment of forest scenery visual quality and the sustainable development of tourism in Kanas.
