摘要
利用山东2001-2013年MCD45和2000年土地覆盖类型数据,将山东植被燃烧分为森林、草地和农田燃烧三类.统计分析表明,山东森林火年季空间分布集中,年季间波动较大,总趋势是缓慢增加;山东草地火灾年季空间分布明显,年季间波动较小,总趋势是缓慢增加;山东秸秆燃烧主要分布在平原地区,具有明显的时间性.山东植被燃烧主要集中在低海拔地区,随海拔的增高呈现下降趋势,森林燃烧主要在海拔0～350m,草地火灾主要在海拔300 m以下,农田火灾主要在海拔0～50 m.
By combining MCD45 data of 2001- 2013 and land cover types data in 2000 of Shandong province, we divided Shandong vegetation burning into forest, grassland and farm- land burning three categories. Statistical analysis showed that, Shandong forest fire did show obvious spatial distribution with seasons, and volatile with seasons, with general trend of slowly increasing; Shandong grassland fire show obvious spatial distri- bution with seasons, and had less volatile with seasons, also with general trend of slowly increasing; straw burning distribu- ted mainly in the plain area, with obvious temporality. Shan- dong burning of vegetation mainly concentrated in altitude, with the increasing of elevation showed a trend of decline. Forest burning is mainly between 0~350 m above sea level, the grass- land fire is main under 300 m, and farmland fire is main be- tween 0 to 50 m.
