运用克里格空间数据制图和传统统计分析相结合的方法对2001—2008年黔南州森林春季防火期主要气象因子与林火情况进行研究,结果表明:黔南州森林春季防火期内降雨量、蒸发量和最大风速相对空间分布不均匀,而最高气温、最小空气相对湿度则相反;空间分布上存在一定的水平地带性和垂直地带性,时间动态明显;森林火灾次数及火场面积呈逐渐增加趋势;空间分布上以都匀、平塘和罗甸3地为分界线,东南部6个县市森林火灾次数及火场面积大于西北部6县市。
By means of the combination of Kriging spatial data mapping and traditional statistical analysis, the main meteorological factors and forest fires of Qiannan Prefecture during spring fire season from 2001 to 2008 were studied. The results showed that: , The relative spatial distribution of evaporation and maximum wind speed is not uniform, while the maximum temperature and the minimum relative humidity of air are opposite. There is some horizontal and vertical zonality in spatial distribution, and the time is obviously dynamic. The number of forest fires and the area of fire field increase gradually The distribution of land use is divided by Duyun, Pingtang and Luodian in the spatial distribution. The number of forest fires and the fire area in 6 counties and cities in the southeast are greater than those in 6 counties in the northwest.
