| The grassland landscape is one of the important components of the natural landscape.The improvement of people’s material life quality has promoted the rapid rise of tourism.The man-made activities it brings and the damage to the development and utilization of tourist destinations have become a problem that cannot be ignored today..Therefore,this paper takes the grassland landscape of Kanas scenic area as the research object,and sets up 6 sample plots according to tourism interference and non-tourism interference.Based on the sample survey,the analytic hierarchy process(AHP method)is used to determine and calculate the sample plots.The three methods of ecological influence and beauty evaluation method(SBE method)measure the aesthetic value of Kanas grassland landscape,compare the correlation between the three methods,and explore the aesthetic value conversion of the three on the spatial scale.The results are as follows:(1)The ecological impact of plots disturbed by tourism is higher than that of plots not disturbed by tourism.It shows that the ecological impact is one of the important indicators for evaluating the ecological quality of a region.It is closely related to the various indicators of the community.These indicators determine the level of ecological impact,that is,the greater the above indicators,the smaller the ecological impact,The better the ecological environment;the lower the above indicators,the greater the ecological impact and the worse the ecological environment.(2)Comprehensive evaluation of Kanas plant populations through the AHP method shows that Kanas plants are generally ecological> ornamental> adaptability> economic.By further scoring the sample plots,it can be seen that the comprehensive scores of the plots disturbed by tourism are lower than those of the plots not disturbed by tourism.(3)The beauty score of the plots disturbed by tourism is lower than that of the plots not disturbed by tourism,indicating that the height,density,coverage,above-ground biomass and species diversity in the community have an important impact on the beauty score Areas with a certain height of dense plants,high vegetation coverage,and rich species that have not been disturbed by tourism are more likely to be favored by the public than areas with low vegetation or low vegetation coverage caused by tourism interference.(4)There is a certain degree of correlation between the ecological impact degree and the SBE method and AHP method.A certain degree of aesthetic value conversion can be carried out on the spatial scale between each other,and the ecological impact degree can be used as one of the methods of landscape evaluation instead of the other two methods.There is a certain degree of rationality. |
