漓江流域土地利用变化及与旅游发展关系研究

以典型旅游目的地漓江流域为对象，基于1973-2016年Landsat遥感影像，解译获取土地利用数据，借助RS、GIS技术，运用动态度、转移矩阵等方法，分析土地利用变化时空特征，进而探讨其与旅游发展的关系。结果表明，1973-2016年漓江流域林地、建设用地和未利用地持续增加，耕地快速减少，水域小幅下降，草地先减后增；不同时期各土地利用类型单一动态度中，建设用地增加最快，2001-2016年具有最大的综合动态度；建设用地与游客人数和旅游总收入呈显著正相关，耕地、水域与游客人数和旅游总收入呈显著负相关；土地利用变化与旅游产业呈现较强相关性，1973-2001年漓江流域旅游产业体量小，土地利用变化的主要影响因素为大面积种植结构调整和城乡建设活动，2001-2016年旅游业发展为地区主导产业，土地利用变化主要受林果种植、景区景点开发、旅游设施建设以及阳朔、兴安等地的旅游城镇化影响。研究结果可为漓江流域土地管理和旅游资源合理利用提供科学依据。

Changes of Land Use and Its Relationship with Tourism Development in Lijiang River Basin

Lijiang river basin,a typical tourist destination,was taken as the research object.Based on the Landsat remote sensing images of Lijiang river basin during 1973-2016,land use types were extracted to analyze the space-time characteristics of land use changes and its relationship with tourism development with the help of RS and GIS technologies,dynamic degree,transfer matrix and other methods.The results showed that the areas of woodland,construction land and unused land areas increased continuously,the area of farmland decreased constantly,the area of waterbody decreased slightly,and a fluctuant increase was found in grassland from 1973 to 2016.Among the single land use dynamic degrees in different periods,the construction land increased the fastest.The construction land in different periods had the maximum dynamic degree.The comprehensive dynamic degree was the largest in 2001-2016.The number of tourist reception and total tourism revenue were significantly and positively correlated with construction land,and significantly and negatively correlated with farmland and waterbody.Land use change had a strong correlation with tourism industry.The tourism volume of Lijiang river basin was small during 1973-2001,and the main influencing factors of land use change were large-scale planting structure adjustment and urban and rural construction activities.From 2001 to 2016,tourism developed into a leading industry in the region,and land use change was mainly affected by the establishment of forest,scenic spot development,construction of tourism facilities and the tourism urbanization in Yangshuo,Xingan and other places.The results could provide scientific basis for land management and tourism resources rational utilization in Lijiang river basin.
