刍议枯死松树的天空地协同监测技术体系建设 总被引：1，自引：0，他引：1
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。 相似文献

The severity and large spatial extent of the current mountain pine beetle outbreak in western North America has prompted research into methods for surveying the location and extent of beetle impacts using remotely sensed data. New forms of remotely sensed data and methods of image analysis have emerged in recent years, which have the potential to provide information on mountain pine beetle red-attack damage that complements information gathered from existing survey methods. The main objective of this review is to summarize previous and current contributions of remote sensing to the survey of mountain pine beetle impacts. The potential and limits of remotely sensed data for the detection and mapping of mountain pine beetle impacts, over a range of attack stages, are identified and synthesized. The secondary objective of this review is to highlight those methods or data sources that currently have operational potential and that the authors believe warrant further research in support of ongoing planning and management activities. Emphasis is placed on the different information needs associated with the various spatial scales of forest management: regional, landscape, and local. The findings of this review indicate that remotely sensed data is useful for mapping red-attack damage across a range of image data types and scales of inquiry. The review concludes with recommendations for future research, and suggestions for operational standards to guide the use of remotely sensed data for the survey of mountain pine beetle impacts. 相似文献

This paper describes the development of a decision support system (DSS) for prevention planning and emergency management of
forest fire events that incorporates weather data management, a geographical data viewer, a priori danger forecasting and
fire propagation modeling, automatic fire detection, and optimal resource dispatching. Collection, input, storage, management,
and analysis of the information rely on advanced and automated methodologies using remote sensing, GPS, digital mapping, and
geographic information systems. The results included short-term dynamic fire danger indices developed for improved and realistic
prevention and pre-suppression planning. An automatic fire detection technology based on infrared video was developed and
successfully tested on site. Several models for understanding fire propagation on forest fires have been proposed for practical
application. Additionally, a DSS was developed with the innovation of covering wildland fire hazard management entirely, providing
a complete coverage of technical and administrative activities that support decision makers in real time. The DSS was tested
for high fire seasons in two different sites in South Europe. 相似文献

Heavy off-road traffic causes soil compaction and rutting, which can significantly reduce the yield of forest stands. Reliable information on terrain trafficability, that is, the ability of terrain to support the passage of vehicles, would enable significant enhancement of wood procurement planning and reduction of soil damage. The objective here was to determine the feasibility of airborne scanning light detection and ranging (LiDAR)-derived digital terrain models (DTM) in terrain trafficability mapping. Soil damage was inventoried from a total of 13?km of forwarding trails, and a logistic regression model was fitted for predicting the event of soil damage. DTM-derived soil wetness indices performed well as predictor variables, and DTM-derived local binary patterns also proved useful in terrain trafficability mapping. A prediction accuracy of 83.6% (Cohen’s kappa of 0.38) was observed for soil damage probability modelling, using only DTM-derived predictors, and a corresponding accuracy of 85.0% (kappa of 0.45) was achieved when an existing soil map was used as well. In addition to the topography-related features, soil stoniness proved to be a critical factor affecting soil resistance to rutting. Our results indicate that the utilisation of LiDAR-derived elevation data for terrain trafficability mapping is a feasible method in sustainable forest management. 相似文献
