摘　　要：利用松原市2021年的遥感影像、土地利用图、行政区划图以及相关统计数据,在RS与GIS的技术支持下,采用GIS空间分析、景观格局指数研究、面积损失评价方法等来确定景观格局分析的最佳粒度。结果表明:松原市景观的最佳分析粒度为90 m。分析景观格局指数随粒度变化的响应得到整体适宜粒度域为90~150 m,利用面积损失评价方法在粒度为90 m时,土地面积变化指数最小,此时面积精度损失最少,所以确定最佳分析粒度为90 m。Using the remote sensing image,land use map,administrative division map and related statistical data of Songyuan City in 2021,with the technical support of RS and GIS,the optimal granularity of landscape pattern analysis was determined by using GIS spatial analysis,landscape pattern index research and area loss evaluation method.The result showed that the best analysis granularity of Songyuan landscape was 90 m.By analyzing the response of landscape pattern index with grain size change,the overall suitable granularity range was 90-150 m.When the grain size was 90 m by using the area loss evaluation method,the land area change index was the smallest,and at this time,the loss of area accuracy was the least,so the optimal analysis granularity was 90 m.
