摘要

美国国家航空航天局(NASA)在2016年发现了几起从地方到全球范围的严重野火。然而,对野火动态及其后果的深入研究仍然不足。本研究旨在了解尼泊尔野火动态及其对森林资源和公共财产的影响。采用中分辨率成像光谱辐射计(MODIS)对尼泊尔2016年的活火数据进行了分析。审查了国内外发表的有关野火的文章、报告、网站和媒体。使用ArcGIS和MS Excel对数据进行分析。结果表明,2016年森林火灾多发地区出现异常,对森林资源和公共财产造成不利影响。据记载,焚烧的日子有一百四十天。森林火灾发生密度为0.09人/ km2,燃烧面积为3.4公顷/ km2,比过去15年增加了33%左右。巨大的森林资源及其有形和无形的服务在2016年失去了。按当地市场价格计算,森林资源损失约为1175万印度卢比(107798美元)。共有11人死亡,100多人受伤。本研究的结果将为未来的实施者、研究人员和决策者提供有用的基线信息。

WILDFIRE DYNAMICS AND ITS EFFECTS ON THE FOREST RESOURCES AND PUBLIC PROPERTY IN NEPAL
 NASA (National Aeronautics and Space Administration) has detected several intensive wildfires from the local to global level in 2016. However, deeper study on the dynamics of wildfire and its consequences are still inadequate. This study was carried out to find wildfire dynamics and its effects on the forest resources and public property in Nepal. Moderate Resolution Imaging Spector-Radiometer (MODIS) was used for active fire data of 2016 in Nepal. Wildfire-related national and international published articles, report, website and media were reviewed. Data were analyzed using ArcGIS and MS Excel. The result showed an abnormal wildfire incidence areas in 2016, adverse effect on the forest resources and public property. One hundred forty burnt days were recorded. Density of wildfire incidence and burnt area were found to be 0.09 number and 3.4 hectares per km2, respectively, which was around 33 % more than of the last 15 years. The huge forest resources and its tangible as well as intangible services were lost during the year of 2016. Loss of forest resources account for about NRs 11,750,000 (US$ 107,798) as per local market price for the year. Total eleven people were killed and over hundred people injured. The findings of the present study will be useful baseline information for implementers, researchers and decision-makers in future.
