Read the map of a certain region in my country and the map of Dongting Lake area changes, and answer the following questions. (1) The special weather that lasts for a long time in this area in early summer is ______. (2

(1) In early summer, it often rains continuously in the Jianghuai area. The main characteristics of Meiyu weather are long-term continuous rainfall, high relative humidity, short sunshine hours, low ground wind, overcast clouds, and continuous rain or intermittent rainfall.

(2) The regional distribution of China’s agricultural production tends to be more reasonable. With the acceleration of urbanization in the Yangtze River Delta region, market demand has increased, traditional agriculture has been transformed and upgraded, and suburban agriculture has also flourished.

(3) Dongting Lake is located in the north of Hunan Province and on the south bank of the Yangtze River. It is the second largest freshwater lake in China. It can reduce the flood pressure in the middle reaches of the Yangtze River during the flood season. However, due to long-term sedimentation and large-scale artificial reclamation, the area of ​​Dongting Lake continues to shrink, and its regulation and storage function is increasingly weakened. At present, our country is implementing the project of returning farmland to lakes, and the area of ​​Dongting Lake is gradually increasing.

(4) The Dongting Lake Plain has flat terrain, sufficient heat and abundant rainfall. It has a mainly subtropical monsoon climate and has good agricultural production conditions. The lake is rich in fish resources and reeds are distributed over a wide area. The main food crops in the plains are rice, and they are also rich in cotton, rape, ramie, tea, lotus, lotus root, etc.

So the answer is: (1) Meiyu; (2) A;

(3) The area of ​​Dongting Lake first decreased and then increased. Originally, the area of ​​Dongting Lake was reduced due to long-term sedimentation and large-scale artificial reclamation. Later, the project of returning farmland to the lake was implemented, and the area of ​​Dongting Lake increased;

(4) Rice; the terrain is flat and the heat is sufficient , abundant rainfall.
