摘要
针对近20年来武夷山市土地利用变化信息相对不足的问题,提出运用现代遥感与GIS技术进行武夷山市土地利用变化动态监测的方法。在分析1996年、2005年和2014年3期Landsat影像的基础上,采用监督分类方法提取土地利用信息,然后采用土地利用转移矩阵分析法和动态度分析法,分析了土地利用类型的时空变化情况及发展趋势。结果表明:1996年以来,武夷山市土地利用变化的特点表现为耕地显著增加,而林地明显减少;20年间其他未利用地和城镇的空间变化幅度很大;经济快速发展,旅游业大力发展等是武夷山市土地利用变化的驱动因素。研究结果对武夷山市的生态环境保护以及探究旅游业对土地利用变化的影响有参考价值。
In view of the relative lack of dynamic change information about Wuyishan land use in recent 20 years,this paper put forwards a method of land use dynamic change monitoring based on Landsat image.The spatial-temporal characteristics of the land use change in the boundary of Wuyishan were quantified and comprehensively analyzed through supervised classification on the basis of remote sensing image acquired in 1996,2005,and2014.Then the transfer matrix analysis method of land use and the dynamic degree analysis method to quantify the land utilization types of spatial and temporal changes and development trend.Some quantitative indexes were adopted,involving land use net change,annual change rate,transition matrix,etc.Results show that：significant land use changes have taken place in the Wuyishan during the period 1996-2014,implying that the cultivated land has been experiencing processes of rapid enhancement,yet the forest land is apparently opposite.During the 20 years,the land use net change of urban build-up land is not so much,but there is a huge transformation in space.In this two phrases,the largest single dynamic degree of land use is virgin land.Rapid economic development and tourist development are probably two major drivers for the spatial-temporal land use changes occurring in the Wuyishan.The research results have important reference value for the ecological environment protection and the research of the effect of the tourism on land use change in Wuyishan city.
