摘要
根据黑河地区1987～2006年林火资料，利用地理信息系统等工具，对黑河地区林火时空动态和分布规律进行了研究。结果表明，黑河近20年林火次数、林火面积随时间发展呈波动性上升趋势，并明显分成1987—1999年的低发阶段和2000—2006年的高发阶段，爱辉区和嫩江县是黑河地区林火次数的主体。黑河地区及各区火烧轮回期均小于黑龙江省的平均值，为黑龙江省火灾高发区。
According to the forest fires materials from 1987 to 2006 in Heilongjiang province, the forest fires＇ time and space dynamic state and its distribution rule were studied by the geography information system. The results showed that forest fires times and area in Heihe in recent 20 years showing ascendant trend with the development of time in fluctuation, it can be divided into two stages： one was the low - developing stage from 1987 to 1999, the other was the high - developing stage from 2000 to 2006. Aihui and Nenjiang were the main part of Heihe forest fires times. As while, providing the modernization forest fires management service for this region.
