近几年,沙尘暴肆虐,给人们的生活造成很大影响。沙尘暴的形成与地球温室效应、厄尔尼诺现象、森林锐减、植被破坏、气候异常等因素有着不可分割的关系。其中,人口膨胀导致的过度开发自然资源、过量砍伐森林、过度开垦土地是沙尘暴频发的主要原因。 In recent years, sandstorms have raged and have had a great impact on people’s lives. The formation of dust storms has an inseparable relationship with the global warming effect, El Nino phenomenon, forest decline, vegetation destruction, climate anomalies and other factors. Among them, the over-exploitation of natural resources caused by population expansion, excessive deforestation, and excessive land reclamation are the main reasons for frequent sandstorms.
