The formation of the county was quite recent, in December 1949, the Communist Party authorities of the Central and Southern Shandong established the Lakes Region Office to manage the four southern lakes (or Nansi Lake)—Weishan, Dushan, Zhaoyang, and Nanyang—and adjacent villages, under the jurisdiction of the Taizao District. The office was abolished in May 1950 and its territory redistributed among nearby counties. It was reestablished in June 1952 under Teng County, but permanently dissolved in 1953 with the creation of Weishan County under Jining Prefecture. Over the following decades, Weishan County underwent multiple administrative boundary adjustments, absorbing territories from neighboring counties in Shandong and Jiangsu provinces, including villages from Jiaxiang, Yutai, Xuecheng, Yi, and Pei County. Notably, large-scale reassignments occurred in 1956, 1957, 1958, 1960, 1983, and 1984. Since 1983, following the dissolution of Jining Prefecture, Weishan County has been administered under the prefecture-level city of Jining.

There are 335 days per year with good air quality. The county holds 3.6 billion cubic meters of freshwater resources, accounting for 45% of Shandong Province's total. Weishan is rich in natural resources. It has 12.7 billion tons of proven coal reserves, mostly shallowly buried with thick seams, consisting largely of high-quality gas and coking coal, making Weishan one of China's key coal production bases. The county also has 12.75 million tons of proven rare earth reserves, located in Xishan, characterized by low levels of impurities such as phosphorus and iron, high grade, and simple smelting processes. It is the only known source in China of typical bastnäsite–cerium resources, making Weishan the country’s second-largest rare earth production base. In addition, there are abundant reserves of limestone, coal gangue, and yellow sand. Weishan Lake is highly fertile and rich in biological resources, classified as a eutrophic lake. It ranks first among large lakes of its kind in China in terms of biological productivity. The lake hosts 78 species of fish and aquatic animals, including the notable "four-nostril carp," Chinese softshell turtle (Pelodiscus sinensis), Chinese mitten crab (Eriocheir sinensis), Chinese mystery snail (Cipangopaludina chinensis), Neocaridina sinensis, and Macrobrachium nipponense. There are 103 species of economically valuable aquatic plants such as reeds, wild rice stems, lotus roots, foxnuts, and gorgon fruit; 205 species of waterfowl and birds including wild ducks, moorhens, and swans, with the "Weishan domestic duck" being particularly well known; and 364 species of planktonic flora and fauna. In terms of transportation, Weishan is traversed by the Beijing–Shanghai Railway, the Beijing-Fuzhou Expressway, National Highway 104, and the Grand Canal (a Class III inland waterway).
