Sustainable development is one of the three main objectives of geoparks. As China has the largest number of global Geoparks, it is of increasing importance for us. The involvement and support of the local community are indispensable to the sustainable development of the Park. But how to achieve the goal in the network age is a big problem. Taking the practice of Mt. Sanqingshan Geopark in recent years as an example, the paper explores the involvement into the Park construction and management by the local residents in different ways, especially through the modern information technology, such as tourism geographic information system (TGIS), in order to share the fruits of Park development, and achieve the sustainable development of the Geoark.
