摘要
利用SPOT卫星影像数据和地面样方数据提取一季稻晚稻种植面积的相对变化率,解决单靠遥感进行一季稻晚稻种植面积监测产生的信息误差,以湖北省一季稻晚稻种植面积为研究区,选取一季稻晚稻光谱特征显著的7-8月份SPOT卫星数据作为遥感数据源,对比分析2009年和2010年湖北省一季稻晚稻种植面积的动态变化,结果表明,湖北省一季稻晚稻种植面积总体变化率为-1.39%.
The informaton of middle-late season rice planting area change was very important for the government decision-making.However,there were no efficient approaches.This paper presented a method based on remote sensing to obtain the information of middle-late season rice planting area change.Taking some middle-late season rice planting areas in Hubei Province as a study area and selecting the SPOT mult-spectral images at 7-8months as a remote sensing data source with special spectral characteristics of middle-late season rice,it was concluded that the dynamic variance ratio of middle-late season rice planting area was-1.39% by comparison with the results at 2009and 2010.
