摘　　要：综述生态气象灾害定义、类型和特点,分析广西4种主要生态气象灾害的气候成因,在此基础上分析生态气象灾害现状与危害。气象因子是生态气象灾害产生、发展的重要自然因素,强降雨、干旱等灾害性天气气候事件以及气候变化是导致广西生态气象灾害的主要气象因素。近年来,广西水土流失、石漠化等生态气象灾害得到有效控制,但滨海湿地生态系统退化和生物入侵仍在持续。This paper summarizes the definition,types and characteristics of eco-meteorological disasters,analyses the climatic causes of four major eco-meteorological disasters in Guangxi,and on this basis,investigate the current situation and hazards of eco-meteorological disasters.Meteorological factors are important natural factors for the generation and development of eco-meteorological disasters.Severe rainfall,drought and other disastrous weather as well as climate change are the main meteorological factors leading to eco-meteorological disasters in Guangxi.In recent years,eco-meteorological disasters such as soil erosion and rocky desertification in Guangxi have been effectively controlled,but the degradation of coastal wetland ecosystem and biological invasion continue.
