国产ZY1-02C卫星数据在新疆典型毒草白喉乌头遥感监测中的适用性分析

Research on the possibility of remote sensing monitoring of Aconitum leucostomum by ZY1-02C satellite in Xinjiang

选择新疆新源县那拉提草原白喉乌头的典型分布区阿乌赞夏牧场作为研究对象,应用2011年底发射的国产ZY1-02C卫星的P/MS数据,综合应用RS和GIS技术,在遥感影像预处理的基础上,根据不同地类的光谱特征进行监督分类,对研究区白喉乌头的空间分布进行分割提取,并进行精度验证,探讨其在监测新疆草原典型毒草白喉乌头(Aconitum leucostomum)空间分布的可行性。结果显示,白喉乌头解译精度达88%,影像总体精度86.6%。结论:国产卫星ZY1-02C的P/MS数据用于监测草原毒草白喉乌头具有较好的可行性。

Based on P/MS data of the Chinese ZY1-02C satellite launched at the end of 2011 and preprocessing of the satellite images, Xinjiang was divided and selected with accuracy verification by methods of combining remote sensing and GIS techniques according to classification and supervision of spectral characteristics of different earth, and spatial distribution of Aconitum leucostomum in Awuzan rangeland was a typical distribution area located in the Nalati prairie of Xinyuan. The results showed that accuracy of A. leuca^tomum reached 88% and overall accuracy was 86.6%, which suggested that using ZY1-02C satellite＇s data for monitoring A. leucostomum in grassland indicated better feasible.
