摘  要:
利用2010年8月3日环境资源卫星(HJ1B-CCD1)数据,采用归一化植被指数(NDVI)阈值方法将森林、柑橘、农田、草地等8月植被覆盖高的地物与河流、城镇、道路植被覆盖小的地方作分类处理,然后利用2010年2月14日TERRA卫星上的ASTAR L1B数据,采用特征值提取技术将森林、柑橘、农田、草地等特征值(色度)差异较大的地物提取出来,得到2010年宜都市柑橘的空间分布,其结果与10个柑橘调查区GPS测量的区域相符合;计算得知宜都柑橘种植面积为18 440 hm2,与2009年湖北省农业统计年鉴中宜都柑橘种植面积15 334 hm2相近。

摘  要:
Using NDVI threshold-based method and 2010 / 08 / 03 HJ1B-CCD1 data, the ground objects were classified into two types in Yidu area. One type had high NDVI values including forest, citrus, field and grass, while another type had low NDVI values including river, city and road on August. Citrus plantations were separated from the forest, field and grass using the feature extraction method and 2010 / 2 / 14 ASTAR L1B data. The retrieval citrus spatial distribution was accorded with the areas of 10 citrus orchards located by GPS. The area of citrus plantation was calculated as 18 440 hm2in Yidu city, approaching to 15 334 hm2published in Agriculture Statistical Annals of Hubei province in 2009 for the citrus plantation area in Yidu city.
