风景名胜区应对山洪的思考

Discussion on Mountain Flood Defense Countermeasures in Mingyue Mountain Scenic Area

摘要: 风景名胜区地势陡峭，山体地势高出周边幅度大，对水气输送形成阻碍，往往使冷暖空气在此滞留，不时有强降雨出现，引发山洪泥石流灾害。遭遇短历时强降雨的情况下，多处飞流直下，山洪突发性强、成灾快，防御难度大，若应对处理不及时，极易造成群死群伤事件，影响社会和谐稳定。本次研究重点选择江西省宜春市明月山风景名胜区几次大的山洪过程，对数据进行科学分析，提出非工程措施和完善预警、科学有效地避险等方面的应对方案，其研究成果在2019年7月明月山风景名胜区突发山洪险情时得到印证，取得积极社会效果，得到江西省水利厅的肯定，为风景名胜区防御山洪灾害提供参考借鉴。

Abstract: The Mingyue mountain is higher than the surrounding area, which hinders the water and air transportation, often makes the cold and warm air stay here, and sometimes there is heavy rainfall, which causes the flood and debris flow disasters. In the case of a short period of heavy rainfall, many places fly straight down, flash flood disaster and defense difficulties. It is easy to cause mass casualties if is not handled in a timely manner, which affect social harmony and stability. This study focuses on several major flash flood processes in Mingyue mountain scenic area, Yichun city, Jiangxi province, and makes scientific analysis of the data, and puts forward non-engineering measures, as well as improvement of early warning and effective risk avoidance countermeasures. We have obtained positive social effects when the Mingyue mountain torrents were happened in July 2019, which was affirmed by the Water Conservancy Department of Jiangxi Province, and provided reference for the prevention of mountain torrents in the national parks of scenic area.
