What are the knowledge points of aerial photography geography in China and Jiangsu?

Aerial photography China Jiangsu geographical knowledge points are:

1. Origin of Qiongzhou Strait: partial fault subsidence (filling movement) in Qiongzhou Strait. In this process, the power to shape the surface morphology comes from the interior of the earth (internal force).

2. Advantages of train ferry: direct loading of train carriages saves port construction costs; There is no need to load and unload goods at the dock, which avoids the loss of goods and saves the loading and unloading expenses; Shorten operation time, speed up cargo turnover and improve transportation efficiency.

3. The natural location conditions of Haikou City: it is located in the estuary delta with flat terrain; Tropical monsoon climate, long summer without winter, influenced by the ocean, abundant rainfall; Nandujiang provides sufficient water for the formation of Haikou.

4. The biological resources in Hengduan Mountain area are rich and unique: low latitude and sufficient heat; Affected by the southwest monsoon, there is more precipitation; The terrain is undulating, the vertical zonality is obviously different, and the water-heat combination is rich; Complex terrain, easy to form local microclimate; The mountains are high and the valleys are deep, the environment is closed, and it is less affected by human activities, so that special species can be preserved to this day.

5. The value of Undaria pinnatifida: ecological value: it requires high growth and can indicate the change of lake water quality; Play a certain role in purifying water quality. Economic value: as a local specialty food, it can be eaten; Meet people's aesthetic needs and stimulate tourism.
