摘要

在过去几年里,斯里兰卡的森林火灾一直呈上升趋势。以往的研究证明,斯里兰卡的大多数森林火灾都是人为因素造成的。本研究的主要目的是确定位于中央高地西坡的圣克莱尔瀑布附近地区森林火灾的原因,并调查其影响和减少森林火灾的措施。本研究使用了原始数据和二手数据。原始数据是通过问卷调查和重点小组访谈获得的,访谈对象为霍利鲁德、瓦特戈达和德翁 GN 分区的研究区域。从随机抽样中采访了二十(20)户家庭。与努瓦拉埃利亚森林保护局、茶园公司和塔拉瓦克勒警察局进行了重点小组访谈。2010 年至 2020 年期间的降雨量和气温数据来自科伦坡气象局的二手数据。83 名受访者表示,森林火灾多发于 1 月至 4 月,因为这几个月气温高、降雨量低。瀑布区左岸和右岸的低坡上没有帕塔纳草原,而人工林和茶园则在高坡上蔓延。据林业部门称,帕塔纳草原的林下植物和林下植被是该地区的易燃物。96 名受访者表示,森林火灾是人们为了从 Kothmale Oya 捕捞鱼类,在岩石上升起篝火并焚烧鱼类而故意引发的。这些火焰会引发火灾。63 名受访者表示,森林火灾是为了让 Thalawakele 种植园定居点的人们为牛群提供 "丛林饲料"。他们希望通过在旱季放火,使雨季的鲜草生长茂盛。22 名受访者表示,森林火灾是为了狩猎而故意纵火。大部分火灾发生在科特马勒奥亚河左岸。为了防止在这一地区发生火灾,在右岸建立了防火带,如无花草走廊和有花草走廊,作为缓冲区。该防火带由 Thalawakele 种植公司负责维护。森林火灾发生时,林业局会发送短信提醒社区。建议种植花木作为绿化带,以减少该地区火灾的发生。 关键词中部高地 随机取样 篝火 哈娜树

Is the Forest Fire adjacent to St. Clair’s Waterfall Natural or Man-made?
Forest fires have been showing an increasing trend in Sri Lanka over the past few years. Previous studies proved that most of the forest fires in Sri Lanka were caused by human factors. The main objective of this study is to identify the causes of forest fires in close areas of St. Clair‘s fall, which is situated on the western slope of the Central Highlands and to investigate the impacts and measures to reduce forest fires. Primary data as well as secondary data were used for this study. Primary data was obtained through a questionnaire survey and focused group interviews from the study area of Hollyrood, Wattegoda, and Dewon GN Division. Twenty (20) households have been interviewed from the random sampling. Focused group interviews were held with the Nuwara Eliya Forest Conservation Department, Tea Estate companies and Thalawakele Police Station. Rainfall and temperature data were taken as secondary data for the period from 2010 to 2020 from the Department of Meteorology, Colombo. 83 respondents stated that forest fires occurs from January to April because of the high temperature and low rainfall recorded in these months. Patana grasslands are spared on the lower slopes of the left and right banks of waterfall area and plantation forest and Tea plantation have spread in the higher part of the slope. According to the Forest Department, the understory of Patana grassland and undergrowth for forest plantations are exposures to fire in this area. 96 respondents stated that forest fires are purposely started by the people to catch fish from the Kothmale Oya, build bonfire on the rock, and burn fish. Fires are generated through those flames. 63 stated that forest fires are done for ―jungle based feedings‖ for cattle herds by the people in the Thalawakele plantation settlement. They expect fresh grass to boom in the rainy seasons by setting fires in the dry season. 22 respondents stated that forest fires are purposely done for hunting purposes. Most of the fires occur on the left bank of the Kothmale Oya River. In order to prevent fires in this area, the fire breaks fire belt and such as corridors without and with floras are established as buffer zones on the right bank. This fire belt is maintain by Thalawakele Plantation Company. When a forest fire occurs, the Forest Department sends the SMS message to alert the community. Planting hana trees as a green belt can be recommended to reduce the occurrence of fires in this area.  Keywords: Central Highlands, Random sampling, Bonfire, Hana trees
