| Under the background of " The beautiful country " strategy implementation, rural tourism, which originated in the early 1990s, becomes a powerful tool to accelerate Socialist new rural construction and break the dual structure. But at the same time, the game of rural tourism between protection and development has become the main contradiction, especially for the waterfront village with fabulous landscape resource and fragile ecological environment, has been facing more serious challenge. In previous research, people rarely put tourism impact into spatial patterns of research framework. Based on this situation, we should make clear the waterfront and rural settlement spatial pattern and its tourism impact, in order to promote sustainable development of rural settlements in the problem to be solved. Rural settlements area of Erhai Lake in Dali has an abundance of water, so that its spatial pattern characteristics and tourism impact studies has a very great guiding significance for the waterfront and rural settlement spatial pattern. Research content and the conclusions were as follows:Waterfront and rural settlement spatial evolution reveals the background and basic research of Erhai Lake spatial pattern under the influence of tourism. In the research section of waterfront rural settlement spatial evolution:with ArcGIS10.2 software technologies, we make the spatial distribution of quantitative analysis and qualitative interpretation on land use expanse and spatial distribution evolution of waterfront rural settlement spatial landscape ecology research system. Erhai Lake water village settlement space evolution has following features:1.Construction land evolution is the most significant all over the integral land use structure; 2. Village settlement land, which brought by Urbanization, has turned out weakened; 3.Village settlement distribution near Erhai Lake of regional are increased; 4. Land use expanse of village settlement are growing by scale expansion.Under the influence of tourism, study on the spatial pattern of rural settlement in Erhai Lake is divided into two levels:one is the use of space syntax with DaLi City Road axis of rural settlement spatial analysis, overlay POI business function data, we analysis the function of tourism in waterfront and rural settlement spatial distribution. Then we conclude:the waterfront of rural settlement, which close to Erhai Lake coastline, is most closely associated with the tourism business, especially prominent in Xi Zhou Zhen. The second level is on the basis of the conclusions of the first level study. With POI commercial function database, Erhai Lake coastline waterfront and rural settlement are divided into " agriculture ", and " agriculture+tourism "and the" tourism+agriculture ", which are three different levels of development of the waterfront and rural settlements,. In the same time we select " rural " dark village," agriculture+tourism-" newborn Yi," tourism+agriculture " Tao Yuan village, three rural settlements in Xi Zhou Zhen. Dethmap and CAD space analysis software are used to analyze qualitatively on the three villages space form, the relationship between architectural space and commercial functions. In above research of two level based on reveals tourism effect of Erhai Lake village settlement space pattern features for following four points:1. Village settlement commercial type meets the regular of function adapted space by circle layer type distribution; 2. Village settlement tourism commercial is guided by spatial waterfront, which has beads chain type bank line agglomeration; 3. The aggregation degree of Village settlement space form migrate towards to water tourism function space; 4. Tourism development is useful to continue the authenticity of the rural settlements architectural space.Spatial pattern characteristics of Erhai Lake rural settlements, under the influence of tourism impact, are essentially the mutual adaptation between spatial and functional process. Preliminary conclusion in this study, is helpful to guide waterfront tourism development of rural settlements, promote the protection of waterfront and rural settlements, and has certain practical value on sustainable development policy formulation of rural settlements tourism. |
