What are the favorable conditions and constraints for the development of agriculture in Northwest Ch

Favorable conditions: 1. Sufficient light, long sunshine time, large temperature difference between day and night. It is beneficial to the accumulation of organic matter in watermelon and cantaloupe and increases sugar.

2. Abundant biological resources. The abundant biological resources in the northwest region are unique conditions for the development of the food industry.

3. The land is vast. The northwest region is vast and sparsely populated, with a large land area. Some plants can be cultivated that are suitable for their geographical environment.

Constraints: 1. Irrigation problems. Although the Northwest region is rich in water resources, most of it is glacier water and snow water, which cannot be directly used.

2.The climate is arid and lacks water, which is not conducive to the irrigation of crops.

3. Cultivated land fertility. Due to the climate of this area, the soil is not fertile, and it is difficult for general crops to grow.

Northwest China is administratively divided into five provinces: Shaanxi Province, Gansu Province, Qinghai Province, Ningxia Hui Autonomous Region, and Xinjiang Uygur Autonomous Region. Northwest China is located in the interior of northwest China, and the main climatic characteristics of this region are scarce precipitation and arid climate. Due to its location in the hinterland of the Eurasian continent, Northwest China has a continental arid and semi-arid climate and an alpine climate.

It has the characteristics of vast area, drought and water shortage, widespread desert, more sandstorms, fragile ecology, sparse population, rich mineral resources, difficult development, long international borders, and favorable to the border.

The light is sufficient, the sunshine hours are long, and the temperature difference between day and night is large. It is beneficial to the accumulation of organic matter in watermelon and cantaloupe and increases sugar.

The main factors restricting the development of agriculture in Northwest China are (b)a lack of mineral resources.

b Low water resources.

c Solar energy resources are scarce.

d Low level of science and technology.

Northwest China is deep inland, far away from the ocean, with less precipitation and drought as the natural characteristics of the region, and the main factor restricting agricultural production in Northwest China is the shortage of water sources

The main factor restricting the development of agriculture in Northwest China is the lack of water sources, which are deep inland, far from the sea, and have scarce precipitation

The fragile living environment of human beings in Northwest China is the main constraint, and the development of Northwest China should not follow the development model of coastal provinces, and the development of Northwest China should be based on the unified and coordinated development model of all provinces focusing on environmental protection. It is necessary to first formulate a strategic plan for development, coordinate the resources and characteristics of the northwestern provinces, and achieve resource sharing, information sharing, benefit sharing, rational overall planning, rigorous planning, long-term vision, not rushing for quick success, and not blindly seeking success.

The favorable conditions for the development of agriculture in the northwest region are as follows:

Advantageous: Northwest China is located inland, and the temperature changes drastically, and the annual precipitation shows a gradual decrease from east to west. Due to the high altitude and less cloud cover, this area has become a high-value area of solar radiation, so the sunlight is good, which is conducive to the growth of crops such as long-staple cotton, sugar beet, and wheat.

The temperature difference between day and night is large, which is conducive to the accumulation of nutrients, and grapes, cantaloupe and other fruits are well-known at home and abroad.

Unfavorable: Drought is the main feature of the natural environment in this region, and the lack of water resources has become a limiting condition for agricultural production in Northwest China.

1. Reading the calendar to take the regional characteristics of China's northwest region:

The climate in Northwest China is arid, precipitation is low, deserts are widely distributed, and agricultural activities are mainly distributed in places where water sources are exposed. The main source of water for the river here is melt water from the high mountains, so the water source in the foothills is more abundant, forming an oasis. Therefore, cultivated land is mainly distributed in the foothills of the flood-alluvial plains or where there are water sources.

2. Economic development in Northwest China

The economic structure of Northwest China is dominated by resource-based industry and traditional agriculture. Among them, the industrial structure is dominated by coal mining, oil mining and non-ferrous metal smelting; The agricultural structure is dominated by irrigated agriculture, oasis agriculture and animal husbandry.

Coal mining and oil exploitation are mainly distributed in Xinjiang Uygur Autonomous Region, irrigated agriculture is mainly distributed in the Hetao area of Ningxia Hui Autonomous Region, oasis agriculture is mainly distributed in Hexi region of Gansu Province, Xinjiang Uygur Autonomous Region Tianshan foothills, and animal husbandry is mainly distributed in Qinghai Province, Ningxia Hui Autonomous Region and Xinjiang Uygur Autonomous Region.

Xinjiang Uygur Autonomous Region is an important temperate fruit producing area in China. Ningxia Hui Autonomous Region and Xinjiang Uygur Autonomous Region are important sugar crop producing areas in China. Xinjiang Uygur Autonomous Region and Qinghai Province are important animal husbandry bases in the country.

The temperature difference between day and night is large, and the favorable factor is the abundance of sunlight.

The temperature difference between day and night in Northwest China is large, which is conducive to plant photosynthesis and sugar precipitation. The lower level has plenty of sunshine and is suitable for plant growth. The disadvantages are the scarcity of precipitation, high evaporation, water shortages, and the lack of sufficient water sources for irrigation.

The favorable factor is that there is plenty of sunlight for plants to photosynthesize. The downside is drought and lack of rainfall.

The large temperature difference between day and night is conducive to the accumulation of organic matter.

Personally, I feel that the favorable conditions are the temperature difference between day and night and illumination, and the disadvantage is that there is no very good terrain.

Climate....Condition....and the soil of the north....and transportation in the north, etcfactors....

The main factor influencing the development of agriculture and animal husbandry in Northwest China is water sources. Because the northwest region is deep inland, far from the ocean, and the mountains are blocked, the ocean water vapor is difficult to reach, and the precipitation is low, and there is drought and water shortage.

Characteristic agriculture in the western region:

The terrain of the western region is dominated by plateaus and basins. The eastern part is dominated by grassland and desert landscapes; There are large areas of desert distribution in the western basin; Only sparse oases appear at the edge of the basin. All this shows that the Northwest Territories is a region with drought as the main natural feature.

1.Northwest China is the main pastoral area in China. Inner Mongolia is mainly temperate grassland pastures; Xinjiang is predominantly mountainous pastures. The three hippos and three rivers cattle in Inner Mongolia, the fine-wool sheep in Xinjiang, and the Tan sheep in Ningxia are all famous breeds.

2.In addition to animal husbandry, irrigation agriculture was developed in the northwest using river water and mountain snow meltwater.

Water source, because all the water comes from the Qinghai-Tibet Plateau, the Qinghai-Tibet Plateau is full of ice and snow, so a large amount of water is all on the Qinghai-Tibet Plateau, and the use of karez to irrigate water to the oasis agriculture, so we can vigorously develop agriculture, that is, as long as the factor is water.

Advantageous: The natural conditions are superior and the sunshine hours are long, which is conducive to the accumulation of crop sugar.

Unfavorable: Poor traffic conditions, which are not conducive to long-distance transportation of crops.

Water resources, because the exercises in the textbook in the second year of junior high school have, the answer is water resources, adopt me, o( o thank you.

Physical Geography of the Northwest Territories:

1.Topographic features: It is mainly located in the second step of China's topography, mainly plateaus and basins.

The Inner Mongolia Plateau (including the Hetao Plain, the Ningxia Plain, and the Hexi Corridor) is flat and open, with typical temperate grasslands in the east and deserts and Gobi in the central and western regions. The Kunlun Mountains, the Tianshan Mountains, and the Altai Mountains are all important mountain ranges in central Asia, with snow on the tops of the mountains and vast grasslands at the foot of the mountains. Among them, the Tianshan Mountains lie in the middle, dividing Xinjiang into two parts, north and south, and the mountains are mostly submerged basins and valleys (Turpan Basin, Ili River Valley, etc.), and the altitude of Ayding Lake is -156 meters, which is the lowest point of China's land. The southern part is the largest Tarim Basin in China, the surface landscape is distributed in a circular shape, the "oasis" is the main local agricultural area, the largest Taklamakan Desert in China in the middle, and the Tarim River, the longest inland river in China, is distributed in the middle; To the north of the Tianshan Mountains is the Junggar Basin, the second largest basin in China, and the Gurbantunggut Desert is the second largest desert in China.

2.Climatic characteristics: deep inland, belonging to a typical temperate continental climate.

The winter is cold and the summer is hot, and the daily and annual temperature range are very large (the Turpan Basin is the "hot pole" of China); Precipitation is scarce, the annual precipitation is less than 400 mm, and the climate is dry (the annual precipitation in the Tarim Basin is less than 50 mm, which is the "dry pole" of China).

3.Hydrological characteristics: small water volume, short flood season, large sediment content of rivers, many inland rivers, glacial meltwater is the main recharge water source, and there are large areas without flow. The upper reaches of the Yellow River have a large drop and abundant water power.

4.Main rivers: Yellow River, Irtysh River (the only river flowing into the Arctic Ocean in China), Tarim River, Ili River.

5.Main lakes: Lop Nur vegetation: The eastern part of the Inner Mongolia Plateau is a typical temperate grassland, and the western part of the central Inner Mongolia Plateau is a temperate desert.

6.Soil: mainly limestone soil and limestone soil. Dominant factor: Decreasing precipitation from east to west.

The state of agricultural development in the Northwest Territories:

1.Agricultural production conditions:

Favorable conditions: high temperature in summer, low volume, strong sunlight, large temperature difference between day and night. The pastures are vast, and there are many wastelands suitable for agriculture. The Xinjiang and Hexi corridors are irrigated with glacial meltwater, and the Ningxia Plain and Hetao Plain are irrigated with Yellow River water.

Unfavorable conditions: long winters and short summers, great impact of cold waves, frequent sandstorms in spring. Precipitation is low, evaporation is strong, agriculture needs irrigation, and irrigation water sources are insufficient. The surface vegetation is poor, the desertification is serious, and the salinization of the Hetao Plain and the Ningxia Plain is serious.

2.Characteristics of agricultural activities: important pastoral areas. Crop farming is dominated by drought, and irrigated agriculture is prominent (Xinjiang is an oasis agriculture). One crop a year, three crops in two years (southern Xinjiang).

3.The status of agriculture in the country: the most important animal husbandry base in the country (Xinjiang, Inner Mongolia), the largest long-staple cotton base, an important irrigated agricultural area (Xinjiang, Ningxia, Hetao), an important temperate fruit producing area (Xinjiang), an important sugar crop base (Inner Mongolia, Xinjiang).

4.Main agricultural products: planting wheat, sugar beet, melons and fruits, cotton, flax (Inner Mongolia). Animal Husbandry Three Hippos, Ili Horses, Three Rivers Cattle, Camels, Inner Mongolia Fine-haired Sheep, Xinjiang Fine-haired Sheep, Altai Big-tailed Sheep, Ningxia Tan Sheep.

The most important natural feature of the Northwest is aridity.

Impact on agricultural development: Northwest China is relatively arid, water resources are scarce, precipitation is difficult to meet the needs of crop growth, and areas with more precipitation can only meet the growth needs of pasture. Therefore, the animal husbandry industry in Northwest China is well developed and it is an important animal husbandry base in China.
