地理大题（Great geographical problem） Port construction: Natural: The geological structure is stable. The topography of the Hong Kong area is flat and conducive to the establishment of the port. A good haven is good for avoiding the wind. The coastline is long and the sea level is flat, without rocks, with good visibility. The harbour is wide in depth. The sea has no ice age. Society: With XX city as the base, the economic hinterland is wide. (Shanghai, for example, forms the transport of sea, land and air.) Maritime convenience. High port equipment, technical support. Conditions of formation of salt fields: A broad, flat beach. Convenient transportation (generally coastal, maritime convenience, favorable to the development of international market.) The temperature is high and the evaporation is high. Lower precipitation (may be in the leeward slope, less affected by the monsoon, as far as possible.) Its sunny and windy. Sandy beach, salt is not easy to infiltration. Here are a few key salt farms: 1. Cloth bag salt field: the largest salt field in Taiwan province, on the southwest coast of Taiwan island. The beach is wide and the land is inclined to be inclined. Rivers are injected with low water volume. The monsoon is strong. It is dry and rainy for half a year, the sun is long, the temperature is high, the evaporation is fast. The seawater has a high salinity. 2. Yinggehai salt field: located in the southwest of hainan island. (summer is in the leeward slope of the southeast monsoon, with little precipitation.) The latitude is low, the temperature is high, the sun has high Angle, the sunshine time is long, the sunlight is strong, the wind is strong, the air is quick, the salt process is short. Located on the southwest coast of hainan island, the plain is flat and wide. Mud sands, salt is not easy to infiltration. 3. Long reed saltland: located on the bohai sea bank. There is a long, broad, flat, muddy beach, and the salt is not easy to infiltrate. The rainy season is s
