刍议枯死松树的天空地协同监测技术体系建设

枯死松树及时精准监测是做好松材线虫病防治的基础,传统人工线路踏查难以保证全覆盖和高时效。高空间分辨率的航空和航天遥感技术可以快速采集区域级地表覆盖数据,获取单木与树丛级森林资源健康状态信息,服务于枯死松树监测;地面调查是航天和航空遥感技术应用不可或缺的组成部分,是实现对松材线虫病疫情遥感监测必不可少的工序。枯死松树的天空地协同监测技术体系的建立,以及天空地遥感技术互为补充的集成运用,是提高松材线虫病监测调查工作实时性、客观性和科学性的重要保障,不仅可为精准监管森林资源提供相应解决方案,也是完善和丰富现有松材线虫病监测普查体系、实现松材线虫病疫情早期发现以及疫情处置监管的有效途径。

Monitoring system construction of dead pine through synergy observation of spaceborne,airborne,and ground remote sensing

The timely and accurate monitoring of dead pine is the first line of defense against pine wilt disease.Traditional manual route inspection is difficult to ensure full coverage and high efficiency.Spaceborne and airborne remote sensing technology with high spatial resolution can acquire regional image data quickly.And the health status information of single tree or cluster that will help to monitor red-attacked trees is accessed.Ground survey process is essential to apply spaceborne and airborne remote sensing to pine wilt disease monitoring.To promote the real-time,objective and scientific nature of ground detail survey,it is an important guarantee to establish the spaceborne,airborne,and ground remote sensing cooperative monitoring technology system of dead pine trees,which can not only provide the corresponding solution for accurate forest resources supervision,but also perfect and enrich the existing survey system of pine wilt disease in China and realize the early detection and supervision of pine wilt disease.
