| The concept of global tourism not only brings development opportunities for the development of tourism villages,but also due to the rapid growth in the scale of tourists and disorderly construction of tourism infrastructure.It leads to the destruction of biodiversity,the encroachment of all kinds of natural ecological land,the pollution of the environment and so on.It is an effective way to promote the natural ecological protection and maintain the sustainable development of the countryside to carry out the research on the succession development and reconstruction of the ecological space.Taking Wolong Village of Chaling County as the research object,this paper comprehensively combs the theoretical basis and related research progress of tourism villages ecological space,applies the theories of landscape ecology,systematics and other related disciplines,and is supported by GIS and ENVI software platform,Combining GIS spatial analysis method,participatory rural assessment method,ecological sensitivity evaluation and the minimal cumulative resistance model.In this paper,the evolution process and characteristics of Wolong village ecological space are analyzed,and the constituent elements of ecological space system are identified.The results show that:(1)The participatory rural assessment method is used to analyze the four development stages of Wolong village construction space,and the historical evolution process of ecological space is deduced in reverse.It is divided into the original stage of ecological space,the point occupation stage of ecological space,the surface destruction stage of ecological space and the rapid erosion stage of ecological space.The disorderly construction of tourism infrastructure is the main reason for a series of ecological problems,such as the continuous encroachment of Wolong village ecological space,the obvious decline of ecological space quality,the lack of villagers’ awareness of ecological protection and so on.(2)According to the principle of landscape ecology,the three elements of rural ecological space are divided into ecological source,ecological corridor and ecological node,and the ecological sensitivity evaluation,resistance surface construction and the minimum cumulative resistance model are adopted.Six ecological sources,15 ecological corridors and 22 ecological nodes were identified,which provided a construction framework for the structure and layout analysis of the constituent elements of ecological space reconstruction in Wolong Village.(3)According to the ecological analysis of the evolution characteristics,trends and constituent elements of Wolong village ecological space,combined with the objectives,principles and ideas of tourism villages ecological space reconstruction,the construction framework based on identification results is optimized and sorted out.Reconstruct the ecological space network system of Wolong village,and put forward the control guidelines and design strategies of all kinds of ecological space elements,which provide planning reference for realizing the optimization of Wolong village ecological space and promoting the implementation of the rural revitalization strategy. |
