中文摘要：

收集分析了浙江省6a的火情监测与记录，及相应的环境林分信息，如坡度、树种、龄级、郁闭度、林地权属，整理分析了火、植被以及人为环境梯度间的关系。结果发现，浙江省火损失的格局，呈现明显的时空分布特点。淳安县、开化县、龙泉市等地的林火损失最高，义乌市、永康市、江山市等地区居中，而余杭市、余姚市、海宁市等地的林火损失最低。而且，主要的火损失发生在2月至4月，以白天10—17时的火损失最大。火季（2月至4月）晴冷干燥，中等程度温度和降雨加上冬日积累的枯枝落叶及加剧的人为活动及火源，造成了主要的森林蓄积量损失。在各种权属的林地中，集体所有林地的蓄积量损失最多，约占总损失量的80％。各林种中，松树最易着火，由此造成的总损失量也最大，火的数目与林木蓄积量损失约占总量的60％。研究可以为森林规划和经营提供参考。

英文摘要：

In this study, the fire records in the years of 2000-2005 in Zhejiang Province were collected and ana- lyzed, and related forest environmental information, e. g., slope, species, age, canopy density, land ownership, temperature and annual precipitation, was compiled to investigate relationship among the fire, vegetation and envi- ronment. The results show that fire losses in Chunan, Kaihua Counties and Longquan City are the highest, fire los- ses in Yiwu, Yongkang and Jiangshan Cities are in the intermediate stage, and the fire losses in Yuhang Yuyao and Haining Cities are the lowest. In fire season （February to April） , the weather is clear and dry, forest volume loss reaches the maximum with the middle class of temperature, precipitation, accumulated fuels from winter, and enhanced human activity and ignitions due to controlled burning in the period. The accumulative amount loss of the collective - owned forest is the highest among forest belongings, and accounts for 80% of the total loss. Pine trees experience the most frequent fires and the largest fire loss （ about 60% of the total）. The study could give a reference to forest planning and management.
