通过对搜集的全国滑坡损毁农田典型案例的发生时间和发生地点进行统计分析，研究典型突发性地质灾害损毁农田的时空分布规律，得出以下结论：大部分的滑坡损毁农田的案例发生时间为雨季（4~9月）；空间分布在以水田为主的耕地中分布最多，绝大部分位于西南各省，秦巴-西南山地高原区是灾毁农田空间分布最集中的区域，从空间上看，滑坡损毁农田主要对我国长江流域主产区粮食安全产生一定的影响。

After statistically analyzing time and location in typical landslide-damaged farmland cases all over China, we conduct the research on spatial and temporal distribution of landslide-damaged farmland and conclude that most of landslide-damaged farmland cases occured in rainy season (from April to September) and dis-tributed in farmland dominated by paddy field in Southwest China, especially in Qin Ba - southwest mountain plateau region. Land-slide-damaged farmland mainly have a certain impact on the food security in the Yangtze River basin.
