大兴安岭林区是我国优质树种落叶松和樟子松的故乡,每年都有大量木材源源运往祖国各地,是我国重要的林业生产基地。然而,由于这里春秋降水稀少,气候干燥,密林内枯枝、杂草多年沉积形成很厚的腐质层,极易发生林火,火灾频繁。据大兴安岭地区气象台和东北航空护林局加格达奇航空护林的科技人员经过三年的密切合作,研究了大兴安岭林区近20年的林火发生规律,普查分析了火灾实况,统计计算十几万个气象数据,从中筛选出气温、风速、降水、湿度等气象要素,春秋两季植被生长情况,积雪覆盖程度等14个指标因子,用模糊数学方法建立数学模型,在微机上开发应用,研究出
Daxinganling forest is the hometown of China’s high-quality species of larch and Pinus sylvestris, each year a large number of origin of timber shipped to all over the country, is China’s important forestry production base. However, due to the rare rainfall in spring and autumn, dry climate, dry branches in the jungle, weeds deposited for many years to form a thick layer of humus, prone to forest fires and frequent fires. After three years of close cooperation, scientists from Daxing’anling Meteorological Observatory and Northeast Aviation Forest Protection Bureau of Jiagedaqi Aviation Forest Protection studied the law of forest fires in the forest of Daxinganling for nearly 20 years. The census analyzed the actual situation of fires and the statistical calculation of more than 100,000 A meteorological data, from which selected 14 indicators such as temperature, wind speed, precipitation, humidity and other meteorological elements, vegetation growth in the spring and autumn, snow cover and so on, using fuzzy mathematics to establish mathematical model, the development and application of microcomputer Out
