中国草原火灾风险动态分布特征及管理对策研究

Study on Grassland Fire Risk Dynamic Distribution Characteristic and Management Policy

利用我国牧区1991～2005年的草原火灾资料,用统计方法分析了我国牧区草原火灾风险的时空动态分布特征.研究发现,随着经济的发展草原火灾的发生次数呈增长趋势,我国草原火灾风险正不断加大,草原火灾造成的损失也在逐年递增;每年的4月份是我国草原火灾的高峰期,10月份产生一个小高峰期;内蒙古、新疆、甘肃是我国草原火灾经济损失最严重的3个省份.针对我国目前草原防火减灾中出现的问题提出了管理对策.

Grassland fire is one of the main disasters in grassland.Using corresponding data of grassland fire form 1991 to 2005 and statistical method,the spatial and temporal distributing characteristics of grassland fire risk were studied.It was found that grassland fire risk is rising following economic development.The losses caused by grassland fire are also rising.The grassland fire occurred in high frequency in April and October.Inter Mongolia,Xinjiang and Gansu were badly influenced by grassland fire on economy.At last, the management policy for reducing grassland fire was put forward.
