Please solve my problem! The question I want in the geography open class!

1: Construction of toy processing plant Garment processing, labor-intensive. Rationale:

In the pre-reform and opening up period, the Pearl River Delta was an open circle, with abundant labor and cheap labor. It's not a huge consumer market, and it was very poor at the beginning of the reform, right? After processing, they are all sold out.

2: After the 90s, the reform and opening up has been developed, the labor-intensive industries of the past have been unbearable, and the tired industries have been transferred to the Pearl River Delta, because the labor force has also increased, and investors in the Pearl River Delta have not had much profit to engage in labor-intensive industries, and the impact on the environment is also large, and technology-based industries should be established. Electronics factory, Because of the reform and opening up, China's scientific and technological strength has been developed.

3: Industrialization drives urbanization, and cities have more taxes and continue to build. Industrialization has brought migrant workers, and migrant workers have to consume it, which has brought countless business opportunities to the region.

4: The Yangtze River Delta, compared with the Pearl River Delta, has the largest urban agglomeration, Shanghai is an international metropolis, and the talent advantage is more obvious. The economic development of the Yangtze River Delta is more stable.

The use of the Yangtze River water transport can contact major cities in the mainland, Chongqing, Wuhan, etc., and it is more convenient to obtain raw materials. Cheaper.

5: (1) It can radiate the suburban economy and drive the development of suburban cities.

2) The environmental and ecological problems of the Pearl River Delta are serious water pollution, which can be explained by the water quality of the Pearl River. Serious soil erosion and serious domestic garbage pollution, 6: Foxconn should transform its industry and upgrade.

Low labor costs have no place in the Pearl River Delta and should be transferred to major cities in the mainland. I will summarize what I said and hope for my answer.

1 Garment factories have a huge consumer market for labor resources.

2 Electronics factory technology has the support of scientific and technological forces.

4. Adjacent to Hong Kong, Macao and Taiwan, Southeast Asia, huge consumer market, convenient transportation, talent advantage, ** policy.

5 (1) The Yangtze River Delta is dominated by science and technology, and (2) acid rain, the shrinkage of the delta, and the inflow of seawater.

From 1980 to 1990, labor-intensive industries, such as shoe factories, garment factories, etc., were relatively low-tech industries. Labor costs are relatively low, and some industries in Hong Kong, Taiwan and other places have been transferred.

90 years digital, electronic, technology-intensive.

1: Rainy weather. Cause: Updrafts prevail in cyclone-controlled areas. The air contains a lot of moisture, the airflow rises, and the temperature decreases. Rainfall is formed.

2: Winter: strong winds, sandstorms, cold snaps.

Summer: hot and dry (e.g. dry weather, summer conditions in Mediterranean climate).

First of all, it is necessary to clarify a basic principle: at the middle school level, the cloudy or sunny weather in geography is mainly determined by the vertical movement of the air.

Next, there's the knowledge about cyclones and anticyclones:

1. Cyclone and anticyclone are common weather systems that affect weather changes, cyclones are air vortices accompanied by low pressure, under its control, the air flow converges and rises in the vertical direction, so it forms rainy weather.

2. Contrary to cyclones, anticyclones are air vortices accompanied by high pressure, under its control, the air flow sinks and diverges in the vertical direction, so it mostly forms clear weather. In winter, it is mostly dry and cold, and in summer, it is hot and dry.

I really hope that your problem can be solved, and we will communicate with you if you have any shortcomings.

1: Rainy weather. The cyclone is low pressure, and the low pressure forms an updraft, and a large amount of moisture contained in the air condenses during the rise, so it becomes clouds and rains. Cyclones generally do not occur simply and are often associated with fronts to form frontal cyclones, and the general causes of rain are these.

2. Anticyclone is high pressure.

In winter, anticyclones are prone to strong winds and cold snaps, and weather forecasts can often be heard under the influence of the Siberian high pressure, and there will be cold snaps in the near future.

Summer anticyclones tend to cause arid and hot climates if they form on land. However, due to the influence of land and sea climate, the main high pressure in summer is located on the ocean surface, such as the Hawaiian high pressure.
