基于ArcGIS空间分析的土地利用变更监测

Land use change monitoring based on ArcGIS spatial analysis

为可靠掌握土地利用变更情况,提升土地资源的有效管理水平,提出基于ArcGIS空间分析的土地利用变更监测方法。以数据处理模块提供的卫星遥感影像为基础,通过ArcGIS完成土地卫星遥感图像的滤波和增强处理;将处理后的遥感影像输入分类模块中,通过该模块中的多尺度土地利用多分类网络,提取土地利用分类结果;在此基础上,变化监测模块计算土地利用转移矩阵、动态度以及年综合变化率结果,实现土地利用变更监测。测试结果显示:该方法可有效处理图像中的噪声点,降低噪声点对于图像质量的影响,有效提取土地利用类别,计算耕地、林地、草地、建设用地等土地利用变更情况,精准确定土地变更区域。

In order to reliably grasp the situation of land use change and improve the effective management level of land resources,a land use change monitoring method based on ArcGIS spatial analysis was proposed.Based on the satellite remote sensing images provided by the data processing module,the land satellite remote sensing images are filtered and enhanced by ArcGIS.The processed remote sensing images were input into the classification module,and the land use classification results were extracted through the multi-scale land use classification network in the module.On this basis,the change monitoring module calculates the results of land use transfer matrix,dynamic attitude and annual comprehensive change rate to realize land use change monitoring.Test results show that this method can effectively process noise points in images,reduce the impact of noise points on image quality,effectively extract land use categories,calculate land use changes such as cultivated land,forest land,grassland and construction land,and accurately determine land change areas.
