Nanji island is located in the subtropical zone, with superior natural environment and distinctive features. 1990 in September, 1990 was approved by the State Council as one of the first five national marine nature reserves in China, and became the only marine nature reserve included in the UNESCO World Biosphere Reserve Network in February. It is a special marine ecosystem reserve with the protection of marine biodiversity as the goal and marine shellfish and algae and their ecological environment as the main targets. Nanji Archipelago is located in the southeast of Zhejiang Province and belongs to Pingyang County. The whole archipelago consists of 52 islands (with an area of more than 500 square meters), with a total coastline of 75km and a land area of 1 1. 13km2. [1] Nanji Islands have been eroded and impacted by waves and tides for a long time, with exposed bedrock and mostly steep cliffs. The coastline of the archipelago is tortuous, with many headlands and many bays. The landform is mainly marine erosion landform, and the marine landform is undeveloped. Nanji Archipelago is far from the mainland, with clear water and low sediment concentration. The bottom of sea area is mainly silty clay. The seabed topography inclines from west to east to south, and the water depth is generally between 15m-25m. The northeast and southwest of nanji island are deep-water passages with a water depth of more than 30m and the deepest point of 45m. Nanji island is the main island, located in the center of the archipelago, with geographical coordinates of 27 27 ′ n,12105 ′ e, and the nearest point to the mainland in the west is 45km. The island is southeast-northwest, with a total length of about 5.3km, the widest point from east to west is 3.3km, and the narrowest point is only150m. The area is 7.64 square kilometers, the highest point is 229 meters above sea level, and the coastline is 24.8 kilometers long. There are four bays, Dasha 'ao, Huoju 'ao, Mazu 'ao and Guo 'ao, which are located in the southeast and northwest respectively, hence the name of nanji island. Nanji Islands is now an island township system in Pingyang County, with Nanji Town. The resident population is 2272, and the seasonal floating population (mainly fishery operators) is more than 8000. In 2000, the GDP was 3 1.52 million yuan, and the per capita income was about 5 1.00 yuan, which was a low-level resource development economy. Mainly fishery, followed by other economic components; In fishery, the acquisition of fish resources is the main thing, followed by the processing of fish products; In the acquisition of fish resources, natural collection and fishing are the main methods, followed by the open sea. Nanji island sea area is rich in local germplasm resources such as grouper, red snapper, brown salmon and perch, and it is a paradise for shellfish, algae and aquatic animals and plants. In the early 1960s, the first large kelp nursery factory in China was built in nanji island, with a nursery pool of 5,000 square meters and an annual seedling raising capacity of 300 million plants. The achievement of "producing cysts with kelp in low temperature room in summer" is still widely used. At the end of 1960s, the technique of raising seedlings with filiform shells of laver was successful, which lost the great development of laver breeding in southern Zhejiang and northern Fujian. In the mid-1970s, laver farming in northern Zhejiang and Fujian developed greatly. In the mid-1970s, Zhejiang and Fujian provinces took the lead in carrying out the southward migration of Mytilus edulis, held the first training course on culture technology of Mytilus edulis in Zhejiang Province, and then successfully carried out artificial breeding of Mytilus edulis. In the mid-1980s, he participated in the national key problem of scallop and Haliotis discus hannai breeding and won the second prize of Zhejiang Science and Technology Progress Award. In the early 1990s, following the ecological research of Chlamys farreri, the reproductive biology of Sargassum fusiforme made a breakthrough, and the research on fry technology reached the international advanced level, and won the third prize of scientific and technological progress of the Ministry of Agriculture. In recent years, it has undertaken 13 experimental research projects (including 4 national projects and 2 provincial projects), and achieved many scientific and technological achievements, such as introduction, breeding and trial breeding of northern population of bay scallop, hybrid breeding of abalone, research on abalone seedling raising technology, and reproductive biology of grouper, of which two have obtained national patents. Nanji Archipelago is not only a marine nature reserve and a national marine nature reserve in the UNESCO World Biozone Reserve Network, but also a scenic spot in Zhejiang Province. According to historical records: "In the tenth year of Wanli in the Ming Dynasty (1582), there was a deputy governor of the Southern Dynasty, and in the eighteenth year of Shunzhi in the Qing Dynasty (166 1), he moved." At the end of Ming Dynasty and the beginning of Qing Dynasty, Zheng Chenggong, a national hero, took Nanji Island as his base, managed in various ways and sought to restore the Ming Dynasty, leaving many cultural landscapes. According to Pingyang County Records, Nanji Islands is rich in tourism resources and has a beautiful environment, especially granite bedrock and joints, which have been eroded and weathered by waves and collapsed, forming more than 550 kinds of landscapes such as rocky beaches, harbors, headlands, waterways, beaches, gravel, waves, meteorology and biology. There are five scenic spots: Dashaao, Olympic Games, Sanpanwei, Radar and Zhuyu Island. Pingyang nanji island Ocean Investment Co., Ltd. was established in 1995. It organically combines the development of tourism and comprehensively develops scenic tourism resources. Breakwater and highway around the island have been built successively, 70 luxury speedboats have been purchased, and Russian wooden houses, mountain villas, seaside bamboo promenades and other resorts have been built. Nowadays, people pursue returning to simplicity. With its charming scenery and beautiful cultural landscape, nanji island has demonstrated the fishing characteristics of its artificial reef fishing ground. Fishing leisure in nanji island is not only about staying on the island, going to the sea, watching the sea, fishing, eating seafood and buying seafood, but also integrating traditional island customs with modern physical exercise, outdoor adventure and learning advanced marine scientific and cultural knowledge, which has profound marine culture and fishery culture connotation. And through fishing villages, as fishermen, singing fishing songs, driving fishing boats and fishing nets, as well as underwater diving, underwater weddings, desert island exploration, beach bonfires, beach volleyball, bunkers, surfing, windsurfing and other colorful and modern new projects, attracting domestic and foreign tourists.
