| 摘 要： | 高分一号卫星是为提升我国高分辨率数据自给率自主发射的卫星，在土地利用监测方面具有重要的应用价值。将GF-1卫星影像与多源数据影像进行对比能够挖掘各数据源在土地利用动态监测方面的差异性。本文以云南省杞麓湖流域为研究区，选取最新的Sentinel-2、GF-1和Landsat 8卫星遥感影像进行土地利用分类，以第二次全国土地利用调查数据为基期数据，结合野外实地调研和土地利用转移矩阵开展土地利用现状和演变分析，得出以下结论：①杞麓湖流域的水域、建设用地、耕地和林地自中心向外呈现出圈层分布的特征，与第二次全国土地调查结果相比，水域、耕地、林地3种类型的自然景观面积减少，而建设用地和其他用地受人类活动的影响，面积大幅增加，变化主要集中在杞麓湖周边的纳古镇和河西镇。②Sentinel-2卫星影像与GF-1卫星影像均具有较高的空间分辨率，二者对土地利用变化评估的结果相近，均优于Landsat 8卫星影像，其中GF-1卫星影像具有较高的应用价值。

| Abstract: | GF-1 satellite is an autonomous satellite launched to improve the self-sufficiency of high-resolution data in China. It has an important application in land use monitoring. Comparison between GF-1 satellite images and multi-source images can excavate the differences of various data sources in land use dynamic monitoring. In this paper, the Qilu lake watershed in Yunnan province is taken as the research area. The latest Sentinel-2, GF-1 and Landsat 8 remote sensing images are selected for land use classification. Based on the data of the second national land use survey, the current situation and evolution of land use are analyzed by combining field investigation and land use transfer matrix. The results show that:① The water area, construction land, cultivated land and forest land in Qilu lake watershed show the characteristics of circle distribution from the center to the outside. Compared with the results of the second national land survey, the natural landscape area of water area, arable land and forest land is reduced, while the area of construction land and other land is greatly increased under the influence of human activities, and the changes are mainly concentrated around Qilu lake, with Nagu town and Hexi town as the typical examples. ② Both Sentinel-2 satellite image and GF-1 satellite image have high spatial resolution. The results of land use change assessment derived from Sentinel-2 and GF-1 are similar and both are better than that derived from Landsat 8 satellite image. GF-1 satellite image has high application potential. |
