Rural landscape is the resource base to develop rural tourism. Under the background of tourism development, the “rurality” of rural landscape is threatened by the reverse change of rural landscape patterns, which goes against the sustainable development of rural tourism. From the perspective of landscape ecology, the paper makes a deep analysis of negative influence of the development of rural tourism nowadays on rural landscape ecology and explores how to actively and effectively protect rural landscape so as to promote the sustainable and healthy development of rural landscape tourism. Moreover, methods and measures aiming to facilitate the rational development of rural landscape are put forward.
