| Abstract: |
| [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. |
