In this study,the fire records in the years of 2000-2005 in Zhejiang Province were collected and analyzed,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 environment. The results show that fire losses in Chunan,Kaihua Counties and Longquan City are the highest,fire losses 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.
