【摘要】 近年来凉山彝族自治州森林火灾频发，且蔓延迅速，扑救难度大。本文选择传统遥感手段，利用遥感卫星和无人机相关数据，以木里藏族自治县森林火灾为背景，明确了可燃物识别及其易燃性的意义；选择地形、地表温度、植被含水情况等因子对目标区域进行评价，并引入生态水(层)概念，将植被生态水作为一种重要的参数因子；分析研究区的自然环境特点，研究森林植被可燃物易燃程度的重要性及其空间分布，并构建一种适用于森林植被茂密地区的可燃物易燃程度评价体系，为降低研究区森林火灾风险提供防控依据。更多还原

【Abstract】 Frequently occurring forest fires in Liangshan county spread rapidly and are difficult to be put out. This paper proposes a method to identify forest combustion and flammablility levels by using traditional remote sensing means, relevant data of remote sensing satellite, UAV, and several selected factors such as terrain, surface temperature, vegetation, and water content. The concept of ecological water(layer) is adopted into our study of the target area to generate a spatial significance distribution on forest combustion and flammability, which can further establish an evaluation system to control and prevent forest fires.更多还原
