基于遥感影像的红树林虫害监测模型

【目的】研究遥感监测对红树林(Mangrove)虫害的适用性。【方法】应用资源一号02C卫星(ZY1-02C)影像和实地调查红树林虫害状况数据,结合影像光谱与纹理特征,采用多元逐步回归分析方法对广西铁山港湾的红树林虫害状况进行估测,并制作研究区红树林虫害状况空间分布图。【结果】估测模型可做为叶片损失情况预测的一种工具。【结论】本研究首次将遥感技术应用于红树林虫害的监测,大大提高红树林虫害的监测效率,项目成果极具推广意义。

Mangrove Pests Monitoring Model based on the Remote Sensing Image

[Objective]To research the applicability of remote sensing monitoring on mangrove pests.[Methods]Based on the image of the 02C satellite (ZY1-02C) and the investigation of the mangrove pest status data on the spot,combined with the image spectrum and texture features,the multi-stepwise regression analysis method was used to estimate the mangrove pests in Guangxi Tieshangang Bay,and the spatial distribution map of mangrove pests status in study area was made.[Results]The research showed that the estimation model could be used as a tool to predict the damage of the leaves.[Conclusion]For the first time,remote sensing technology was applied to monitor mangrove pests,the research improved the monitoring efficiency of mangrove pests greatly.
