From the result of simulate calculation the guangzhou ' s eight times forest fire , the accuracy of simulated fire area is more than 90 percent , so the model can simulate the fire area and the length of the fire accuracy 从广州市8宗森林火灾的蔓延模拟结果看,过火面积的模拟精度约90 % ,能较准确地模拟林火发生时的过火面积和火线长度。
The essential rule of artificial restoration is matching tree by improving soil or matching site by improving tree species , and the livability of the regenerated coniferous forest reflected the affection of the topography on the artificial reforestation 例如地形对林火迹地(重度火烧区和极重度火烧区)针叶林恢复的影响,它实质是地形对人工更新存活率的影响。
Forest fire monitoring technique depends heavily on the provision of image communication & processing technique . it urgently becomes a significant problem how to realize real - time & long - distance monitoring and fire auto - recognition with monitoring systems 林火监测技术的发展越来越离不开图像通信与处理技术的支持,利用监测系统,如何实现远程实时监测和火灾自动监测是急需解决的问题。
In order to increase the accuracy and the widely use of fire spreading model , the paper base on the change state of temperature of the calculus on fire area , use the law of energy conservation , it can give the change of the temperature field ' s mathematical model on the fire area 摘要为了提高林火蔓延模型的准确性和通用性,文中把火场看作一个动态温度场,并从火场上任一微元体任一时刻温度变化状态出发,应用能量守恒定律,建立火灾区域温度场动态变化模型。
