Featuring a tropical oceanic monsoon climate, Sansha boasts rich marine resources in the following aspects: 

Plant resources

Islands in Sansha, especially Xisha Islands, have abundant plant resources, with 80 families, 211 genera and 296 species. 283 species among them are resource plants, taking up 95.6 per cent of the total. Most of the resource plants are edible or can be used for medicine. 

Marine biological resources

The sea area of Sansha is known as a "marine forest" or "deep sea plain", due to the abundance of marine life. There are about 2,000 kinds of fish, as well as rare and precious sea products such as pearl oysters, sea snails, abalone, sea cucumbers, sea urchins, and lobsters. Wildlife on land is mainly sea birds. 

Sea water and deep sea mineral resources

Sea water in Sansha has a high salinity, with total salt content at over 70 trillion tons. There are broad prospects for developing salt extraction in the area.

The deep sea of Sansha holds abundant reserves of minerals with great extraction value, including such metals as iron, manganese, copper, cobalt, zinc and nonmetal minerals as zeolite, coral and limestone. The area also has rich reserves in manganese nodules and cobalt-rich crust.

Energy resources

The sea area around Sansha has extremely rich energy resources of numerous types, including wind and solar power, tidal and sea current energy, and other renewable sources, as well as ample sea water chemical energy and gas and oil reserves, giving the area spectacular prospects for industrial development.

Due to their unique geographical conditions, Xisha Islands, Zhongsha Islands and Nansha Islands enjoy prosperous tourism development potential. Numerous small islands scattered in a broad sea area of 2 million sq km with tropical oceanic monsoon scenery constitute a great potential for tourism development. 

Yongxing Island is the largest of the Xisha Islands and the entire South China Sea islands. It is the political, military and cultural center of Sansha city. The founding of Sansha promoted the construction of production and living facilities including administrative offices, post offices, banks, shops, libraries, hotels, radio and television stations, meteorological stations, marine stations, aquatic stations, hospitals, soilless vegetables greenhouses and leisure and cultural squares on Yongxing Island. Mobile communication signals cover the entire Xisha Islands. Roads, an airport and three ports that can dock 5000-ton vessels have been constructed, making tourism all the easier.
