Green Space System Planning Practices of Multidimensional Network Construction in High-Density Areas Under the Coexistence Trend of Incremental Planning and Existing Stock Planning

Abstract

Under the background of China’s new normal, urban construction has entered a coexistence trend of incremental planning and existing stock planning, where green space in urban high-density areas are affected by an extreme shortage of land supply. Due to the lack of coordination of complex interests in traditional green space planning which can cause the huge transaction costs. This chapter takes two projects in the city of Tianjin as case studies and discusses existing stock space as a resource for land supply in order to reduce transaction costs for green space. The principle of “dividing levels, connecting networks, and building multi-paths”, and the planning strategy that “turns stock into treasure, connects greens into a network, expands the green to three-dimensional” shows an innovative planning strategy for integrated open spaces of an urban green system, which concentrates on ecological conservation, public service, and community vitality. Through green space networks and three-dimensional and multilevel construction, new planning methods for urban green space systems in high-density areas have been explored for “urban repair and ecological restoration” in this work.
