At present, Urban Green Space System Planning (UGSSP) has been given great attention in China. Specific working phrases of UGSSP, which were always separated and disintegrated from Urban General Planning (UGP), have gradually transformed to synchronize and update with UGP. In 2004, the author took part in the academic research work ofThe Ecological Environment Research of Tianjin Citywhich forms a part ofThe Revision of Tianjin Urban General Planning (2004-2020). In this research period, the author paid more attention to the research of the UGSSP in suburban areas, and gradually put forward the viewpoint of enhancing current contents of UGSSP and adding a new planning layer named Green Space System Planning in Urban Planning Area (GSSP in UPA).This research aims to explore specific contents of the Green Space System Planning that integrates with Urban General Planning. Three aspects of the research significance are outlined below:Adding a new layer of GSSP and increasing leisure space for citizens. The gap between current UGSSP and Urban Regional Green Space System Planning (URGSSP) is so big that a new transitional layer called GSSP in UPA. Concerned special distribution, landscape types and activities, the layer could meet the demands of citizens'playing, leisure and recreational activities.Preserving suburban green spaces and improving urban ecological environment. Presently, bad-controlled and low-management urbanization has happened in suburban areas and large natural spaces have been corroded and polluted. If planners can draw up contents of the GSSP in UPA of which integrated with UGP, and link urban construction with natural environmental protection, urban sustainable development could be possible.Coordinating city and country relationship and confining urban sprawl. GSSP in UPA, which can assign suitable developing space for citues and countries , leading the development of regional spaces form new functional groups, and avoid cities expanding around original urban areas,This dissertation takes approach of analogy analysis, epagoge and case study.By analyzing
