摘  要:
引入水稻关键期提取和变化向量分析方法,以江苏省海安县水稻为研究对象,以MODIS数据和环境小卫星数据为主要数据源,分析了2009年水稻物候期内的规律,并根据该指示选择合适的中分辨率数据进行变化向量分析。研究表明,该方法可以有效地反映耕地地块内水稻像元的变化规律,且基于物候关键期内的时相选择可以提高水稻种植面积识别精度。

摘  要:
Introducing analysis method of paddy extraction in critical growth period and variation vectors,with paddy in Haian County of Jiangsu Province as the study subject,taking MODIS data and environment small satellite data as main data source,the law of paddy phenophase period in 2009 was analyzed,and based on these,some appropriate medium resolution data were selected to carry out change vector analysis.The results showed that the method can effectively reflect the change law of paddy pixel,and choosing the time phase based on the analysis of critical phenophase is able to improve the accuracy of extracting the planting area of rice.
