摘要
通过对2000—2015年我国滑坡等地质灾害发生的年际变化和地区分布特征进行综合分析研究,结果表明:我国地质灾害发生次数多,损失大,共发生地质灾害373 469处,造成人员伤亡47 353人,直接经济损失7 330 120万元;研究时段内2006年为灾害高发年,总数高出平均值4.4倍,2013年直接经济损失最大,是平均值的2.3倍;滑坡等地质灾害分布广泛,但集中分布于中南和西南地区,多发于夏季;地质灾害所造成的人员伤亡和经济损失具有地区差异性。
Interannual variation and regional distribution of landslides and other geological disasters in China during 2000-2015 were analyzed,the result showed that: geological disasters not only occurred frequently but also made a very serious result,geological disasters occurred in 373 469 locations which caused 47 353 casualties and direct economic losses of RMB 73 301. 2 million yuan; The geological disasters in 2006 were the highest,total number was 4. 4 times higher than the average. But the 2013 was the most serious year in direct economic losses which was 2. 3 times than that of the average value; Temporal distribution of landslides and other geological disasters mainly occurred in summer,and its spatial distribution were in the Southwest,Central South Regions; The casualties and direct economic losses caused by geological disasters were very disparity in different regions of China.
