基于SPOT高分辨率遥感数据的农作物估产方法研究

Study on Crop Estimation Method Based on SPOT High Resolution Remote Sensing Data

[目的]为了达到基于SPOT高分辨率遥感数据的农作物估产方法研究的目的。[方法]以邢台市为例,利用SPOT-5卫星2.5 m分辨率全色影像与10 m分辨率多光谱影像的融合得到高分辨率多光谱影像,以此对农作物估产方法进行研究。[结果]结果表明,基于SPOT高分辨率遥感数据的农作物估产结果与地面实测结果相比,其检验结果可信。[结论]该研究为农作物遥感估产的实践应用提供了参考依据。

[Objective] the paper was conducted to achieve the study aim of crop estimation method based on SPOT high resolution remote sensing data. [Method] Taking Xintai city as an example, high resolution and muhispectral image was obtained by the image fusion of panchromatic image in 2,5 m resolution and muhispectral image in 10 m resolution by SPOT-satellite. It was used to study the crop estimation method. [Result] Result showed that compared with the result of land surface detection, the result of crop yield estimation was more credible based on SPOT high resolution remote sensing data. [Conclusion] This study offered reference basis for the practical application of crop yield remote sensing estimation.
