摘　　要：为实现对土地资源的均衡配置,平衡地区经济发展与土地利用情况,基于遥感测绘设计了土地资源利用时空变化分析方法。首先,以减少旁向偏差为前提,采用共线方程求解的方式,确定土地资源测绘区域的定点坐标;然后,设定遥感测绘中不同波段的参数范围,获取土地资源中的地物标志图像,并归一化处理图像数据;最后,基于特定范围选择评断指数,构建土地利用变化分析模型,以年度为时段动态描述土地利用变化速度,引入转移矩阵表示土地利用结构和方向,区分土地变化的主导与次要类型,实现对土地资源利用时空变化的具体分析。实验表明:以不同的土地类型作为测试对象,该方法均能够直观地反映各种土地利用类型的年度变化情况,具有实际应用价值。To achieve a balanced allocation of land resources and balance regional economic development and land use,a spatio-temporal changes analysis method for land resource utilization was designed based on remote sensing surveying and mapping.Firstly,with the premise of reducing lateral deviation,the fixed point coordinates of the land resources mapping area were determined by solving collinear equations.Then,the parameter ranges of different bands in remote sensing surveying and mapping were set to obtain landmark images in land resources and normalize the image data.Finally,based on a specific range selection evaluation index,a land use change analysis model was constructed to dynamically describe the speed of land use change over an annual period.The transfer matrix is introduced to represent the structure and direction of land use,distinguish the dominant and secondary types of land change,and realize the specific analysis of spatio-temporal changes in land resource utilization.The experiment shows that taking different land types as test objects,this method can intuitively reflect the annual changes of various land use types,which has practical application value.
