摘要
介绍了江西省山洪灾害系统的总体特征,并根据其发生特征,结合江西省地形、地貌以及气候因子,将江西省划分为3大山洪灾害高发区:赣东北的怀玉山区、江西省西部的罗霄山和九岭山区、江西省东南部的武夷山区。而江西省中北部的湖区平原山洪灾害发生的危险性较小;其他区域则介于两者中间。同时分析了山洪灾害高发区山洪灾害产生的主要影响因子,通过对山洪灾害系统特征研究,能大大减少山洪灾害的突发性,对重点需要防范区域进行布控设防。
The characteristics of mountain torrents disaster system in Jiangxi Province are introduced,and in accordance with their characteristics,the topography,geomorphology and climatic factors,three major regions are divided including Huaiyu Mountain Area in the northeast,Luoxiao Mountain and Jiuling Mountain Areas in the west,and Wuyi Mountain Area in the southeast,which have the high mountain torrents disaster risk,while the risk in the lake plain of the north centre is low.The main factors influencing the mountain torrents disaster in high risk regions are analyzed.
