(1) Features: high temperature throughout the year, with the highest temperature in April-May (2 points);
Reason: low latitude, high sun angle at noon all year round (2 points);
The northern mountainous area blocks the winter wind, and the temperature is also high in the winter half year (2 points);
From April to May, the direct point of the sun moves northward, the solar altitude angle increases, and the temperature rises (2 points);
At this time, the summer monsoon (rainy season) has not yet arrived, and there are many sunny days. (2 points)
(2) The Ganges Plain is flat and low-lying, and it is easy to accumulate water; The rainy season is abundant and prone to floods (4 points);
There are many people and little land, and the demand for food is large; Planting deep rice can make food less affected by floods (4 points);
Fish farming in deep-water fields is a benign agricultural ecosystem, which ensures diversified food supply (4 points).
(3) The northern mountain blocks the winter wind (2 points); And prone to inversion (2 points), relatively stable atmosphere, less precipitation in winter, sunny weather (2 points); The area is densely populated, and the air pollutants emitted by domestic production are large (2 points).
Test analysis:
(1) Read Figure 2 to get the temperature characteristics of City A, including the temperature level, the time when the highest and lowest temperatures appear, and the annual change of temperature. Then, starting with the factors that affect the temperature change, the reasons for the formation of a city's temperature characteristics are analyzed. The main factors that affect the temperature are the height of the sun (changing with latitude and season), the terrain (the terrain is blocked by cold air of different sizes, and the temperature varies with altitude) and the weather (there are many sunny days, which are easy to form continuous high temperature, rainy days, the highest temperature is not high, and the temperature difference is small).
(2) The reasons for the development of deep rice in the Ganges Plain are mainly analyzed from two aspects: First, the Ganges Plain is low-lying, with more precipitation and frequent floods. Natural conditions are suitable for the growth of deep rice, and planting deep rice can also reduce the impact of floods on grain production. On the other hand, considering that deep rice is more conducive to the development of aquaculture, although the yield of deep rice is lower than that of ordinary rice, it is worth developing vigorously, because planting deep rice can increase the income of aquaculture and help maintain soil fertility.
(3) Combined with the formation conditions of haze weather. Small wind, inversion weather and sunny days are the natural conditions for the formation of haze weather; There are a lot of dust in the air, and the emission of air pollutants is mostly the man-made cause of haze weather.
