Abstract:

To study the impact of different underlying surfaces on meteorological elements and regional climate, as well as their climate effects, analysis of variance was adopted to compare meteorological elements of four different underlying surfaces, including shrimp paddy fields, lakes, rural areas, and cities. The significance and climate effects of each meteorological element difference were analyzed. The results showed that the degree of influence of four different underlying surfaces on various meteorological elements was as follows: wind speed > rainfall > maximum temperature > minimum temperature > humidity > average temperature. The order of the degree of influence of different underlying surfaces on wind speed and humidity was consistent as follows: lakes > shrimp rice fields > rural areas > cities. Lakes and shrimp rice fields have a cooling effect in summer and a warming effect in winter and spring. Shrimp rice fields have a greater cooling effect on the highest temperature than lakes, and lakes have a greater warming effect on the lowest temperature than shrimp rice fields. Shrimp rice fields have regulatory effects on wind, temperature, and humidity, and have good climatic and ecological benefits. This study provides scientific basis for protecting the environment and climate resources, and is of great significance for promoting the benign transformation of the ecological environment.
