68. The agricultural feature of Xinjiang is oasis agriculture, which is rich in cotton, sugar beet and many kinds of fruits and vegetables based on unique light and heat conditions. The red series in Xinjiang are: tomatoes, pomegranate, medlar and so on. The reason is that there is a lot of heat and sunshine in summer, which is beneficial to the coloring of fruits and vegetables. The reason why melons and fruits are particularly sweet: The large temperature difference between day and night in summer is conducive to the accumulation of sugar in melon and fruit sugar crops. The hot and dry summer climate and stable irrigation water sources make Xinjiang a production base of high-quality cotton in China. Xinjiang is rich in oil and gas resources, accounting for about 1/3 of the total land reserves in China, so it has become an important energy base in China.

Before Hong Kong and Macao, after the Pearl River Delta, close cooperation, is vividly called "the front shop and the back factory".
79. The development of cities and towns in the Pearl River Delta region marks a major change in land use pattern, which is mainly due to the prosperity of export-oriented economy and the major adjustment of industrial structure.
79. Urbanization can promote economic development, improve people's living standards and social progress, but it can also bring a series of environmental problems (water pollution, declining air quality, piles of garbage, less green space, etc.). ) and social problems (traffic congestion, vehicle congestion, noise pollution, housing shortage, etc. ).
80. The natural factors that cause soil erosion in the Loess Plateau are: ① bare and broken ground, high valley density, less flat land, more slopes and lack of vegetation protection; ② Loose loess structure, pores and vertical cracks; Many substances are easily soluble in water. ③ Precipitation is concentrated in July and August. Human factors, including people's reclamation, mining, road construction and other activities, make the surface loose.
8 1. Most parts of the Loess Plateau belong to temperate monsoon climate, with hot summer and cold winter, and precipitation concentrated in summer and autumn. The terrain along the Yangtze River is low and flat, and the terrain is mainly plain and hilly.
82. Soil erosion in the Loess Plateau has taken away the fertile soil on the surface and reduced the crop yield. Increase, expand and deepen the valley. As a result, the cultivated land area is reduced; It also transported a lot of sediment to the lower reaches of the Yellow River, which caused great difficulties in river regulation and flood control.
83. The three famous buildings in the history of China are Yellow Crane Tower, Yueyang Tower and Wangtengting Pavilion. The difference in topography between the upper reaches and the middle and lower reaches of the Yangtze River is that the upper reaches are mountains, while the middle and lower reaches are plains and hills.

89. To achieve sustainable development, a region needs to make full use of favorable geographical conditions, rationally transform unfavorable geographical conditions and develop its economy according to local conditions. At the same time, we should also pay attention to strengthening the ties between regions, giving full play to their respective advantages, division of labor and cooperation, mutual benefit, full use of resources and complementary advantages.
78. The Loess Plateau starts from Taihang Mountain in the east, reaches Wushaoling Mountain in the west, Qinling Mountain in the south and the Great Wall in the north. Across Gansu, Ningxia, Shaanxi, Shanxi and other provinces.
79. The loess material in the Loess Plateau is formed by wind. The main landforms of the Loess Plateau are loess tableland, loess headland and loess beam. The areas with serious acid rain pollution in the Yangtze River basin and its vicinity are acid rain areas in southwest, central and east China.
80. Four Geographical Regions of China: According to the differences in geographical location, nature and human geography, China can be divided into four geographical regions.
① The basis for dividing north and south is: climatic conditions (Qinling-Huaihe line).
② North China and Northwest China: precipitation (400 mm annual precipitation line).
③ The basis for dividing the Qinghai-Tibet region into three regions: south, northwest and north: topographic factors (high altitude).
82. Name two basic national conditions of our country: vast territory and great regional differences; China is a developing country with a large population and a low per capita GNP.
1, the geographical location and characteristics of China:
● Latitude position and advantages: China's territory spans a vast latitude from north to south, most of which are located in the mid-latitude area, belonging to the (northern temperature) zone, and a small part is in the (tropical) zone, not in the (cold zone). The huge climate difference provides favorable conditions for the development of (various agricultural economies).
● Land and sea location and advantages: (1) is located in the east of Asia and the west of the Pacific Ocean, which makes the vast area in the east of China (under the influence of humid air flow in summer monsoon, precipitation) rich and is beneficial to (agricultural) production; (2) The eastern region has both land and sea, which is conducive to friendly exchanges with overseas countries; The western region (deep into Eurasia) enables China's land transportation to communicate directly with other countries (Central Asia, West Asia and Europe), which facilitates foreign countries (exchanges and cooperation). (3) There are many excellent harbors along the coast, which are convenient for development (marine industry).
● China has a territorial area of (9.6 million) square kilometers, ranking third in the world after (Russian) and (Canadian). Lulin 14. Clockwise, they are North Korea, (Russia), (Mongolia), Kazakhstan, Kyrgyzstan, Tajikistan, Afghanistan, Pakistan, (India), Nepal, Bhutan, (Myanmar), (Laos) and Vietnam. The land border is more than 20,000 kilometers. There are six countries across the sea: Korea, (Japan), Philippines, (Malaysia), Brunei and (Indonesia).
2. The population of our country
● Population in 2000: (1295) billion.
● The outstanding characteristics of China's population: large population base and rapid population growth.
● Characteristics of population distribution in China: The population distribution (uneven) is bounded by Heihe River in Heilongjiang and Tengchong in Yunnan, with high population density in the (eastern) area and low population density in the (western) area. The western part of China is sparsely populated, but rich in resources. What problems should be paid attention to in the development of the western region? The western region has resource advantages, but the natural environment is relatively fragile. At present, the contradiction between man, land, water and soil is quite acute, and the development of the western region must be based on environmental protection, and it is not possible to develop first and then treat it. )
● Population policy: family planning.
● Content: Control the population and improve the quality of the population.
3. Nationalities in China
There are (56) ethnic groups in China, among which the Han nationality has the largest population and the Zhuang nationality has the largest population.
● Distribution characteristics of Han nationality: Han nationality is distributed all over the country, most concentrated in (central) and (eastern).
● Distribution characteristics of ethnic minorities: mainly concentrated in (northeast), (northwest) and (southwest). Zhuang nationality is the most populous nation. Characteristics of ethnic distribution: (large mixed residence, small settlement).
● National customs:
Nadam Congress (Mongolian)
Dai water-splashing festival, peacock dance,
Keywords Tibetan group dance, Tibetan calendar year,
The long-term encouragement of the (North Korea) nation, etc.
4. The terrain of China
● Topographic features of China: (complex and diverse topography, vast mountains)
● What problems should be paid attention to in the development and protection of mountainous areas:
(1) The mountainous area is rugged, with inconvenient (transportation) and difficult (infrastructure) construction.
(2) When developing and utilizing mountainous areas, special attention should be paid to (ecological environment construction) to prevent and avoid mountain disasters (such as collapse, landslide and debris flow).
● Topographic features of China: (The topography of China is high in the west and low in the east, with a stepped distribution).
Stairs, altitude, main terrain types and boundaries of main terrain areas
The first step, the first step, the second step, Kunlun Mountain-Qilian Mountain-Hengduan Mountain; The second and third steps are Daxinganling-Taihang Mountain-Wushan-Xuefeng Mountain. Qinghai-Tibet Plateau and Qaidam Basin over 4000m.
The second step is 1000-2000m Plateau, Inner Mongolia Plateau, Yunnan-Guizhou Plateau, Loess Plateau, Sichuan Basin, Tarim Basin and Junggar Basin.
The hills, mountains, plains and basins below the third step 500 meters are alternately distributed in the southeast hills, northeast plains, North China plains and the middle and lower reaches of the Yangtze River.
● The influence of the stepped distribution of China's topography on the climate, rivers and traffic in China;
(1) Impact on climate: China's topography is high in the west and low in the east, which is conducive to the humid air flow at sea to advance inland and bring abundant precipitation to vast areas of China.
(2) Impact on rivers: the topography of high in the west and low in the east will inevitably cause rivers in China to flow into the sea from west to east; When the river flows from a higher step to a lower step, the drop is large, resulting in huge water energy.
(3) Impact on traffic: The big river flowing eastward connects the traffic between the east and the west of China, which facilitates the connection between coastal areas and inland areas; The mountain range at the junction of stairs has become a huge obstacle to the east-west traffic in China.
