Abstract:

Nature reserve is the cornerstone of biodiversity conservation,and tourism is an important mode of development of the nature reserve.Based on the landscape scale,3S technology and landscape indices,the paper discussed the change of the landscape patterns in the context of rapid development of tourism in Jiuzhaigou nature reserve during 1975~2007.The results showed that various landscape types of the natural reserve had taken place in different degrees during 33 years.The area of grassland,woodland/shrub,cultivated land had a net decrease,whereas the area of forestland,snow/naked rock,construction land,waters had a net increase.From the point of view of transferred out of proportion,construction land was the largest (13207%),followed by cultivated land (100%),grassland (606%),woodland/shrub(535%),forestland(4.47%),snow/naked rock(321%),whereas waters(207%) was the smallest.Under human activities and natural recovery processes,the degree of landscape fragment continued to increase by 1997;but turned better by 2007.In general,the comprehensive action of forest cutting and natural restoration was the primary driving factor,while the effect of tourism development was relative low for Jiuzhaigou’s landscape changing.Development of tourism had promoted the whole recovery of vegetation in natural reserve,but also added construction land and changed the landscape patterns of vegetation.Only when we instill the principle of “conversation firstly”,and manage scientifically,protection and development can reach a winwin situation.
