摘要
根据北方蔬菜种植生育期特点,选择7~8月份的高分1号(GF1)融合影像、10月份的16 m宽覆盖的GF1影像以及8月份Rapid Eye融合影像,结合耕地本底数据开展提取秋季菜田信息的技术流程研究,并对2013年和2014年大兴区秋季菜田进行了动态监测,同时结合气象等数据分析其时空分布规律和变化原因。
By analyzing the growing characteristic of northern fall vegetable, we chose July to August Gao Fenl ( GFI ) fusion image, October GFI 16 -meter- wide coverage image and October RapidEye fusion image as image data elements, and combined object- oriented approach with cultivated land as background data, extracted the fall vegetable land area. Taking the case of Daxing District in Beijing, this paper used above method to monitor the fall vegetable planting area in 2013 and 2014, and analyzed the temporal -spa- tial variations and probable cause.
