Read a map of China area and a map of Dongting Lake area change, and answer the following questions. (1) The special weather with long duration in early summer in this area is _ _ _ _ _. (2

(1) In early summer, it often rains continuously in Jianghuai area. Meiyu weather is mainly characterized by long-term continuous rainfall, high relative humidity, short sunshine time, low ground wind, overcast clouds and continuous or intermittent rainfall.

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

(3) Dongting Lake, the second largest freshwater lake in China, is located in the north of Hunan Province and the south bank of the Yangtze River. It can alleviate the flood pressure in the flood season in the middle reaches of the Yangtze River. However, due to long-term sediment deposition and large-scale artificial reclamation, the area of Dongting Lake has been shrinking and its storage function has been weakened. At present, China is implementing the project of returning farmland to lakes, and the area of Dongting Lake is gradually increasing.

(4) Dongting Lake Plain is flat, abundant in heat and precipitation, with subtropical monsoon climate and good agricultural production conditions. The lake is rich in fish resources and reeds are widely distributed. Rice is the main food crop in the plain, and cotton, rape, ramie, tea, lotus and lotus root are also abundant.

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

(3) The area of Dongting Lake first decreased and then increased. The area of Dongting Lake decreased after long-term sediment deposition and large-scale artificial reclamation, and increased after the implementation of the project of returning farmland to lake.

(4) rice; Flat terrain, sufficient heat and abundant precipitation.
