(1) The topography of the first basin makes it difficult to emit heat (2 points). The desert is widely distributed, absorbs heat quickly and has a high temperature (2 points). The second basin is affected by subtropical high, and it is sunny.

(2) The climate is suitable, and the lakes and wetlands in Poyang Lake area do not freeze in winter, which is beneficial for winter migratory birds to feed;

Rich in food: Poyang Lake and its tributaries are rich in all kinds of freshwater fish, shrimps and crabs;

Suitable water quality: Poyang Lake has good water quality and fresh air, especially suitable for winter migratory birds;

Moderate location: Poyang Society is located in the north-south center, which is convenient for winter migratory birds to move south or north;

Man-made protection: Jiangxi province and the government and local people along the lake have a strong sense of protection, and winter migratory birds are rarely disturbed.

(3) With the decrease of snow and glaciers on the Qinghai-Tibet Plateau, the ground reflectivity decreases and the ground temperature increases, (2 points) leads to the temperature increase, (2 points).

In summer, the temperature difference between land and sea increases, resulting in a strong southeast monsoon. (2 points)

The rapid advance of rain belt leads to more precipitation in the north and large-scale high temperature weather in the south. (2 points)

(Ground temperature, air temperature, monsoon and south heat and north water, 8 points in total)

Test analysis:

(1) This problem must first locate the geographical location, and then make a concrete analysis according to the local geographical environment. The first place is the Tarim Basin, where the topography is relatively closed, which is not conducive to the diffusion of heat. In addition, there is Taklimakan Desert, the largest desert in China, which is widely distributed, absorbs more heat and has less precipitation. The analysis of area B is relatively simple. In August, the subtropical high controlled the middle and lower reaches of the Yangtze River, and the airflow sank, with less precipitation and high temperature.

(2) This problem can be analyzed from natural conditions and human conditions. Poyang Lake is located in the subtropical monsoon climate zone, where the lake will not freeze in winter, with vast wetlands and abundant food. At the same time, it belongs to the transitional zone between north and south, and the distance between north and south migratory birds is moderate, which provides a natural and superior place for migratory birds to feed and inhabit. From a humanistic point of view, the local population has a high quality and a strong awareness of protecting animals.

(3) This question examines the integrity of the natural environment. The reduction of snow and glaciers in the Qinghai-Tibet Plateau will bring about the linkage reaction of natural environment in other regions. The decrease of snow and glaciers in the Qinghai-Tibet Plateau will directly lead to the decrease of ground reflectivity, the increase of ground temperature and the increase of air temperature. The increase of temperature will lead to the increase of temperature difference and the enhancement of monsoon power, so the southeast monsoon will push forward strongly, accelerate the passage of rain belt, reduce the stay time of rain belt in the south and aggravate the high temperature in the south, while the precipitation in the north will increase relatively.
