三维GIS航空护林系统的建立与运行效益分析

THE BUILD OF AERIAL FOREST PROTECTION AND FIRE CONTROL SYSTEM BASED ON 3D-GIS AND THE ANALYSIS OF OPERATION BENEFIT

以丽江航空护林站为研究区,通过遥感卫星影像、以及DEM数据等基础数据,建立三维GIS航护系统,实现了数据管理系统,火险预测系统、救火指挥系统、灾后评估系统,分别对森林火灾的预防、监测和扑救提供决策服务,为保护丽江护区的林区资源提供了先进的技术支持。同时,在应用模型中分析和评价了利用三维GIS系统进行火场区域定标、火场数据集成和导入的时间效率,评价和分析了局部火区标绘与采集的精度,为救火抢险,保护森林资源减少人员伤亡提供可靠的信息和决策分析。

This article considered the reality of Lijiang aviation forest research station, I develop 3D-GIS system by using some base data, such as remote sensing images, DEM, etc. This system realizes the data management systems, fire forecasting system, fire command system, disaster assessment system to prevent forest fires, monitor and provide decision-making services, so we can provide the technical pledge for protecting forest resource in Lijiang area Finally, this article discusses： In the model of the model of the practical application it analyzes and evaluates the time efficiency, which locate the fire area using 3D-GIS system; it analyzes and evaluates the local fire district collected plotting accuracy; it evaluates the efficiency of integrating the fire data and importing the 3D- GIS system ; as well as the data plotting of the 3D-GIS aerial forest fire protection system compares to the manual paper plotting. So it confirms the advantage at the technical level, but also at the role of in-use of the Forest Protection and Fire Control.
