Water Resources

Jiangsu has rich water resources and the average annual precipitation is 994.5 mm, the runoff depth is 259.8 mm. The province lies along the lower reaches of the five lakes, namely, the Yangtze River, Huai River, Yi River, Shu River and the Si Canal. The Yangtze River traverses the southern part of the province, thus river is the most reliable water resource in Jiangsu.

Jiangsu is cut crisscross with rivers, lakes and canals which altogether form a dense network of waterways. There are large–and-medium-sized lakes such as Tai Lake, Hongze Lake, Gaobao Lake, Luoma Lake, Weishan Lake, etc and branches such as the Grand Canal, Huaimu River, Chuanchang River, Yan River, the Tongyu Canal, the General Irrigation Canal, and the Tongyang Canal, etc.

Deep beneath the wide plain areas distribute the incompact accumulations of the Fourth Age, which holds in store an abundant underground water source. The Xuhuai shallow layer water which is estimated about 2.957 billion stere/year would be worth exploiting for the provincial agriculture irrigation, and the estimated 585 million stere/year of coastal deep underwater would be significant for developing assarts and tidal flats and for lives of people and domestic animals.

Mineral Resources

Jiangsu enjoys the advantage of its rich and typical mineral resources such as non-ferrous metal, clay, building material and rare metal, special non-metal material and etc., resulting from its unique geological position that it is actually located across two geologic structural units, the North China platform and the Yangtze Metaplatform.

Up till now, 133 types of mineral resources have been discovered and 65 of whose reserves have been proved up. Thirty-four types of single mineral reserve such as building material, clay, etc are among the top ten in China. There are 8 kinds of mineral reserves such as niobium-tantalum, calcareously, lime marl, attapulgite clay, carbon dioxide gas and etc in the lists of top ten around the country.

Coal, oil and natural gas are the main energy resources, while sulphur, phosphor, sodium salt, crystal, cyanite, sapphire, diamond, kaolin, limestone, quartzose sand, marble and pottery clay are among the non-metal resources and iron, copper, lead, zinc, silver, gold, strontium and manganese among the metal resources.
