Where most of China s islands are located

Most of China's islands are located in the East China Sea and the South China Sea. China is one of the countries with many islands in the world, and 90% of China's islands are located in the East China Sea and the South China Sea. Taiwan Island, Hainan Island, and Chongming Island are China's No. 1 islands.

I. Second, the third largest island.

China has 6,536 islands with an area of more than 500 square meters, with a total area of more than 72,800 square kilometers and a coastline of kilometers long.

Of these, 450 are inhabited. There are many small islands and few large islands in China, many uninhabited islands and few inhabited islands, and many water-scarce islands and few water-faced islands. There are 3 large islands with an area of more than 1,000 square kilometers in China; Taiwan Island, Hainan Island, Chongming Island.

According to its causes, it can be divided into three categories: bedrock islands, alluvial islands, and coral reef islands. The East China Sea accounts for about 60% of the total number of islands, the South China Sea accounts for about 30%, and the Yellow and Bohai Seas account for about 10%.

Zhoushan Islands, Miaodao Islands, Penghu Islands, and Nanhai Zhudao are the four major archipelagos in China. Zhejiang Province is the province with the largest number of islands in China.

The vast majority of China's islands are located in the waters south of the Yangtze River estuary.

The East China Sea accounts for about 6% of the total number of islands, the South China Sea accounts for about 3%, and the Yellow and Bohai Seas account for about 1%.

There are more than 54 large and small islands in China, with a total area of 10,000 square kilometers, accounting for about one of the country's land area. 8％。The total length of the island's coastline is more than 10,000 kilometers, which is equivalent to 78 of the mainland's coastline. According to its causes, it can be divided into three categories: bedrock islands, alluvial islands and coral reef islands.

According to the genesis of Zhengmu, it can be divided into three categories: bedrock islands, alluvial islands and coral reef islands.

In addition, China has 6,536 islands with an area of more than 500 square meters, with a total area of more than 72,800 square kilometers and a coastline of kilometers long. Of these, 450 are inhabited. There are many small islands and few large islands, many uninhabited islands, few inhabited islands, many water-scarce islands, and few water-bearing islands, and there are three large islands with an area of more than 1,000 square kilometers in China.

The mouth of the Yangtze River is located in the north of Shanghai. The geographical starting and ending points of the Yangtze River Estuary are expressed in many places in the "Shanghai Tongzhi": there are roughly four divisions:

1. East of the first line from the mouth of the Baimao River to Haimen City, Changshu City, Jiangsu Province, and west of the east end of Hengsha Island. It is about 86 kilometers long.

2. The concept is expressed as the concept determined by Cong Wu since 1979, with Xu Liujing as the starting point of the Yangtze River estuary section, and the following flows through Shanghai to the No. 50 light float at the mouth of the sea, with a total length of 167 kilometers, commonly known as the Yangtze River estuary, and its lower mouth is 90 kilometers away from Subeizui to Nanhuizui in the south, and the Yangtze River estuary section in Shanghai is 148 kilometers long.

3. It is expressed as the modern Yangtze River estuary, which refers to the total length of about 232 kilometers from the goosenose mouth of Jiangyin, Jiangsu Province to the mouth of the sea, and the chicken bone reef at the mouth of the sea, flowing through Baoshan District, Chongming County, Pudong New Area and Nanhui County.

Hello, most of China's islands are located in the Zhoushan Islands and the Penghu Islands. It accounts for about 80 percent of the country's islands.

The vast majority of China's islands are located in the waters south of the Yangtze River estuary.

The islands in the East China Sea account for about 60% of the total number of islands, the islands in the South China Sea account for about 30%, and the islands in the Yellow Sea and the Bohai Sea account for about 10%. China has 7,372 islands with an area of more than 500 square meters, and 3 large islands with an area of more than 1,000 square kilometers.

China's islands can be divided into bedrock islands, alluvial islands, and coral reef islands according to their genesis. Islands made of bedrock account for more than 90% of China's total islands; Alluvial island refers to the river entering the sea and the sediment accumulating near the mouth gate to form a sand island, or alluvial island; Coral reef islands are mainly found in the South China Sea.

Submarine volcanic eruptions create a series of volcanic reefs that outcrop the sea, and reef-building corals grow around them, forming reefs.

Biological features of the island

The island creatures present extremely interesting features. The sea is an obstacle to some creatures, but a means of transport for others; Once these creatures settle on a new base, they tend to evolve and develop new traits in an isolated environment.

The long-standing barrier to the sea has resulted in significant differences in fauna and vegetation between even adjacent islands; From this difference, the origin of the island can be deduced.

In addition, any detailed map of the global biodistribution can illustrate the importance of islands in determining the boundaries of the distribution of animal and vegetation types. For example, west of the line between Bali and Lombok and between Borneo and Celebes (the Wallace Line), the island's creatures are Asian.

To the east of that line, although the Lombok Strait is narrow, the vegetation and fauna are Australian. Oceanic islands tend to have only a few fauna, mainly seabirds and insects. There is often a lot of vegetation on the island, and the seeds of the plants are brought to the island by the wind and currents or by birds; However, the plant species are relatively limited.
