Geography Solving 26, Geography Problem Solving,

1. The Wenchang launch base is located at a low latitude and is less affected by the geostrophic deflection force. This is the biggest feature that distinguishes it from several other bases. Secondly, the base is located on the island, not on the mainland.

2. Sun City: The sunshine hours are long, so it is called Sun City.

Moon City: Xichang is narrow from east to west, wide from north to south, and shaped like the moon. In addition, there are long days without rain throughout the year, and there are many opportunities to see the moon at night. Known as Moon City.

3. Sky City: One of China's four major space launch bases.

4. Xiaochun City: The altitude is 1500-2500, the climate is suitable throughout the year, the temperature is moderate, similar to Kunming, so it is called Xiaochun City.

The ratio of 3:5:2 represents that in a certain area, if there are ten people, and the area of the commercial, residential, and industrial areas in the area is equal, there are 3 people living in the commercial area, 5 people living in the residential area, and 2 people living in the industrial area. Five industrial zones, then it can be seen that in the administrative area A, the proportion of population among various land use types should be 3*3:

1*5:4*2, that's what the formula means.

This analysis is based on the combination of population data and land type maps:

5, which means: **6 is located in the residential area, and the proportion of the residential area is 5

11,000, which means: **6 is located in District A, with a population of 11,000 people.

3x3+1x5+4x2, which means: in District A, there are three commercial areas, one residential area, and four industrial areas, which are multiplied by their respective proportions.

5 11 000 (3 3 1 5 4 2), it should be like this: 5 [11 000 (3 3 1 5 4 2)], it is easy to understand.

The middle brackets indicate that the average population ratio of the three commercial areas, residential areas, and industrial areas in District A has been calculated. Multiply by 5 to indicate that **6 is located in a residential area, and the proportion of residential areas is 5.

Thus 5 [11 000 (3 3 1 5 4 2)]=5x500=2500

I don't know if it's right or not, but 5*1100 is what the total population would be if all the places in A were residential areas. 3 3 1 5 4 2) is actually the population composition of the place A is commercial 3*3 residential 5*1 industrial 2*4

I don't know if it's right or not, just an idea.

They are Yichang and Hukou.

3) Yalong River, Minjiang River, Jialing River, Wujiang River, Hanjiang River, Xiangjiang River, Ganjiang River (4) Gongzui, Danjiangkou, Three Gorges, Gezhouba.

5) Dongting Lake, Poyang Lake, Taihu Lake, Hongze Lake, Chaohu Lake.

(1) Stone resources are abundant, widely distributed and varied; Abundant water energy, abundant coal reserves, and sufficient energy; The climate is humid and water is abundant.

2) lead to ecological damage such as vegetation destruction and soil erosion; causing water pollution and atmospheric dust pollution; depletion of stone resources, etc.

3) Increase investment in science and technology, and improve the utilization rate of energy, raw materials and water resources; Timely reclamation or restoration of vegetation in stone mining areas to reduce the hazards of soil erosion; Extend the industrial chain, develop diversified products, strengthen product publicity and brand building, and increase market competitiveness; Improve transportation facilities and increase export capacity.

Too blurry to see clearly.

Hello lz.

First of all, the direction in the top left corner of your hand is wrong!

Up, north, down, south, left, west, right, east is the order of looking at the map, you turn your map 90 degrees clockwise, do you think you mark left, west, right, east?

Then there is the question of the direction of the river, and these contour lines undoubtedly bulge in the same direction.

If b<600, then this is a bulge to a low elevation, which is called a watershed, and it will not form a river.

Only B>600, protruding towards high altitude, will be the catchment line, forming a river.

To sum up, the lower left corner is the northwest direction, which is higher at an altitude, and the upper right corner is the southeast direction, which is lower at an altitude, so it is northwest to southeast, and 1 choose b

From the conclusion of question 1, b = 700, a = 400

800>y>700

400>x>300

So 500>y-x>300

The answer that falls within this range is only B488M

Then there's the image on the right.

The place with the largest groundwater flow velocity is, of course, the place where the dotted line is more dense (with a large drop), so the groundwater flow rate of A is the fastest, and (1) is A

2) There is spring water flowing out, indicating that the diving surface is equal to the altitude.

In the figure, the altitude of A is 140, and the diving surface is 110 115

B altitude 130, diving surface 115

The altitude of C is 110, and the diving surface is 110

Ding altitude 120 130, diving surface 105

Obviously, only C has the opportunity to have spring water, so C should be chosen

3) The altitude of the P point is 120 130, the diving surface is 100 105

So the drilling depth is between 15 and 30.

So at least 15m, is to choose C

First of all, you've got the map in the wrong direction.

Up, north, down, south, left, west, right, east.

Second, the river flows through low terrain, the upper reaches are lower than the lower terrain, and the middle high line area in the map is a valley (how can a river form on a ridge?). ）

The contour line where B is located at 600 is greater than A, and the river flows from the lower left corner to the upper right corner, that is, from the northwest to the southeast.

It has been determined that this place is a valley, and the contour distance is known to be 100 meters, b is 700, a is 400, y b, y 700, x a, x 400

The Y point is more than 700, (below 800), X is more than 300, (higher than 200) and its relative height is more than 400

First of all, b, c are excluded from the range of the eastern hemisphere, and then through the technique, we can know that because a is the range of the eastern hemisphere, and there are other conditions in the question stem, we can easily deduce that the range of a must be large, and a will definitely not be chosen, then only d is left in this problem.

Of course, when practicing, you still have to analyze the questions thoroughly. Since DF is the morning line, it is easy to know that the range above EDF is the night hemisphere, and it can be seen from the figure that the meridian where AD is located is the ** meridian of the night hemisphere, that is, it is 0 o'clock. Now the range of the 22nd is 0° to the east to 180°.

d can be selected by combining the eastern hemisphere range

Feel free to ask, I hope it can help you.

If DF is the morning line, then this is the H point at 6 o'clock on December 22, at this time the 0 degree meridian is 0 a.m. on the 22nd, and the global is from 0 to 180 degrees east on December 22.

Combined with the Eastern Hemisphere's 20 W to 160 E longitude, the range of the Eastern Hemisphere on December 22 is from 0 to 160 E longitude.

Brasilia has a savannah climate with low temperatures; There are significant seasonal variations in precipitation; Rio de Janeiro has a tropical rainforest climate with high temperatures; Precipitation varies little from season to season.

Causes of the temperature difference: Brasilia is located in the Brazilian highlands, with high altitudes and low temperatures.

(1) The city is distributed along the traffic lines and along the river. Reason: There are irrigation water sources, the terrain is relatively flat, conducive to agricultural development, the population and cities are relatively concentrated, there are transportation lines through it, and the transportation is convenient.

2) There is an irrigation water source, sufficient sunlight, a large temperature difference between day and night, and it is located in the tropics, and the heat is sufficient.

3) Land desertification, land salinization, and grassland degradation.

Solution: control population growth, rational allocation of water resources in the upstream, middle and lower reaches, use engineering measures and biological measures to prevent desertification, rational use of land, return farmland to forests and grasslands, and prohibit overgrazing.

(1) Major cities are distributed along rivers and railways.

2) The terrain is flat and the land conditions are good; The high temperature season is long, the weather is sunny, the sun is sufficient, and the temperature difference between day and night is large, which is conducive to the blooming of cotton and peach, and cotton is good; There are rivers that provide irrigation water;

1. It is distributed along the river along the traffic arteries, the terrain is low and flat, the transportation is convenient, and the water source and soil conditions are good, which is conducive to the development of agriculture and animal husbandry.

2. The tropical desert has good climate and thermal conditions, and the river distribution area has fertile soil and sufficient water sources.

3. The forest coverage rate is reduced, the land is desertified, the measures are afforestation, reasonable grazing, reasonable control of cotton planting area, and the development of ecological agriculture.
