基于GF—6卫星的棉花种植面积提取研究——以山东省夏津县为例

Study on Extraction of Cotton Planting Area in Xiajin County Based on GF6 Satellite——Setting Xiajin County in Shandong Province as an Example

摘要:

国产高分卫星6号（简称GF6）具有高分辨率、宽覆盖、高质量和高效成像等特点，可为农业资源遥感监测提供可靠的数据支撑。本研究以GF6卫星影像为主要数据源，综合利用遥感技术理论和方法开展对夏津县棉花种植面积的提取研究，利用同时相的哨兵2号（简称Sentinel2）影像解译结果进行对比分析。研究结果表明：基于GF6卫星的夏津县棉花种植面积提取方案高效、准确，提取精度明显优于Sentinel2卫星，进一步证明了新增了红边波段的GF6卫星能够显著增强作物的识别能力，其在大规模作物种植信息提取方面具有广阔的应用潜力。

Abstract:

The domestic high resolution satellite 6 (GF6 for short) has the characteristics of high resolution, wide coverage, high quality and efficient imaging. It can provide reliable data support for remote sensing monitoring of agricultural resources. In this study, taking GF6 satellite image as the main data source, by using the theory and method of remote sensing technology comprehensively, the cotton planting areas have been extracted in Xiajin county. At the same time, the interpretation results of Sentinel2 (Sentinel2 for short) image are used for comparative analysis. It is showed that the extraction scheme of cotton planting area in Xiajin county based on GF6 satellite is efficient and accurate, and the extraction accuracy is significantly better than that of Sentinel2 satellite. It is proved that the newly added GF6 satellite with red edge band can significantly enhance the recognition ability of crops. It has broad application potential in largescale crop planting information extraction.
