Wen County has been inhabited since the neolithic era, as evidenced by Majiayao culture sites. The area was later inhabited by the Di people. Throughout the centuries, the area was ruled by many different dynasties and kingdoms.[6]
As a result of the 2008 Sichuan earthquake, 93% of households in Wen County had their homes damaged or collapsed. The main road to access the county, China National Highway 212, was also blocked in both directions.[7]
Tea, Codonopsis pilosula, Sichuan pepper, walnuts and olive oil are the main agricultural produce of the region.[8][9][10]
Two reservoirs (Bikou Reservoir and Miaojiaba Reservoir) have been constructed in the Bailong River. The reservoirs serve to provide hydroelectricity, aquaculture, flood control, irrigation and for tourism development.[11] The county holds one fifth of total exploitable hydropower resources of Gansu. Wenxian is also rich in metal deposits, most notably the Yangshan gold mine is Asia's largest Carlin–type gold deposit.[9]
Major rivers in Wen County are the Bailong River, Baishui River,[12] Baima River[13] and Rangshui River.[14]
