The basin covers an area of 2,245 square kilometers; Daye lake system 1339 square kilometers, Baoan lake system 570 square kilometers. Located in the mid-latitude, the solar radiation season varies greatly, far from the ocean, and the surface is mostly a group of mines. In spring and summer, the underlying surface is rough, humidified quickly and convective strongly. In addition, due to the influence of East Asian monsoon circulation, its climate is characterized by hot Leng Xia in winter, distinct seasons, abundant sunshine, sufficient heat energy and abundant rainfall, which is a typical subtropical continental climate in East Asia. The annual average temperature is 65438 07℃. The hottest month (July) averages 29.2℃, and the hottest month (65438+ 10 month) averages 3.9℃.

There are many southeast winds in the territory, and the annual average wind speed is 2.17m per second. The climate is mild and humid, the cold period in winter is short, and the hydrothermal conditions are superior, which is beneficial to crop growth. However, due to the changes of atmospheric circulation, topography and seasons, the climatic factors change greatly year by year, so severe weather such as late spring cold, heavy rain, strong wind and drought in summer and autumn occur from time to time.
