Geopark plays an increasingly important role in construction of ecological civilization and targeted poverty alleviation．Scientific and reasonable function zoning of the Geopark Planning is one of the most important bases to well develop Geopark，and is also the key point and basic requirement for Geopark’s sustainable development．This paper dealt with practical and feasible function division methods that are applicable to the characteristics of geoparks in China from the technology layer of planning，and discussed the coordination relationship between function division planning and development and construction of geoparks．It pointed out some problems existing in the current geopark planning practice in China，such as the problems related to geopark function division and land utilization，protection zoning and general layout， through analyzing the origin and purpose of geopark function division．It also put forward some optimization measures for function division planning of geoparks based on years of experience in geopark planning，so as to provide a reference for the practice of function division planning of geoparks．①Function zoning is the core content of geopark planning，which embodies the requirements of the main functional area on land utilization．Function zoning is based on the need for balanced interests of parties involved in geopark construction and development during space planning，with the fundamental objective to control and guide the land utilization functions，so as to make more rational utilization of national land space．②On the basis of scientific investigation and social research，it is the key to realize the coordinated development of ecosystem integrity protection and public recreational utilization，and it is the industry requirement and obligatory historical mission for geopark planners to strengthen planning cooperation and community participation，to carry out scientific and reasonable function zoning and to make a good balance of land utilization．③Under the guidance of the main functions of each functional area，coordinate the planning and design in aspect of overall layout，integrated service area and route，so as to effectively protect geological relics and the natural environment，promote local economic development and the sustainable utilization of geological relics，and realize the common development of ecological，economic and social benefits of geological relics．
