The drought in Dongting Lake has turned the lake bed into a vast grassland. How much impact does high temperature have on local ecology?

The continuous drought in recent days has had a great impact on the ecological environment in many places. Due to the continuous high temperature and the rapid evaporation of water in Dongting Lake, most of the riverbed of Dongting Lake is exposed, forming a vast grassland. The drought caused by high temperature poses a great threat to the life safety of local people, and also causes serious damage to the local ecological environment, which seriously hinders the local economic development and ecological construction. Drought has not only seriously affected grain production and agricultural development, but also affected the development of the whole national economy and social stability.

With the development of social economy and the increase of social wealth, drought has become one of the natural disasters with the greatest economic loss and the widest influence in China. Due to the occurrence of drought, the problem of water shortage is becoming more and more serious. With the increasingly obvious global warming problem, water shortage is one of the most urgent problems in China.

Therefore, it is particularly important to carry out drought research to prevent drought and solve the problem of water shortage caused by drought in China. The middle and lower reaches of the Yangtze River are one of the most developed areas in China in terms of social productivity and economy. In recent years, with the rapid development of economy, the demand for water is increasing. Due to climate, topography and other reasons, the shortage of water resources not only brings great inconvenience to local people's production and life, but also becomes the biggest obstacle to local economic development. Under this background, how to solve the problem of sustainable utilization of water resources is an urgent problem.

The impact of drought on local ecology is related to the sustainable development of lake basins and the ecological security of the country. With the global warming, the probability of frequent extreme weather increases year by year, which aggravates the deterioration of ecological environment and leads to a series of natural disasters, which seriously threatens people's production and life and national ecological security. Drought is an important global climate and environmental problem in recent years. While these natural disasters occur, we should also learn from them, actively carry out ecological protection and restoration projects of ecosystems, and make better use of wetland ecosystems to cope with global climate change.
