Green space system planning is the most direct method to improve urban ecological environment from the perspective of planning. However, traditional way of green space system planning exposes its limitation of paying attention to only urban area, accompanied by the prominent appeal for the enhancement of urban ecological environment and living environment quality. Therefore, the study gives a preliminary discussion on the method of green spaces system planning based on GI theory by introducing the concept and characteristic of GI, and proposes urban-rural integrated green space environment formed by the organic combination of Hubs, Links, and Sites and an urban green space system able to keep the integrality and consecutiveness of natural ecological process, which offers reference for green space system planning of the new era.
