Abstract:

Evaluations of plan implementation focused on whether the construction of physical space is in accordance with the plan. It is difficult to answer whether the plan target is achieved. This article will evaluate the implementation of the polycentric system plan in Hangzhou core built-up area based on two conformance criteria: Conformance of physical construction and conformance of plan target. The conclusions are as follows. The physical construction of polycentric system is successful. Fifteen city-level centres have been constructed at principal, secondary and sub-secondary levels. Physical construction has successfully guided the transformation of spatial structure from a single principal centre system to two principal centre and multiple sub-centres system. However, the polycentric system fails to achieve the expected effects of the plan target. The level of gathering at newly built public centres are considerably lower than that at traditional public centres, they are hardly to disperse the excessive concentration of public activities from traditional downtown. Meanwhile, the newly built public centres fail to encourage people to visit the nearest blocks for daily public activities. These mainly because the local government enforce the plan by policy, but economic activities still tend to cluster in traditional downtown. What’s more, the expansion of the city is over rapid, residents have not had sufficient time to adjust to the spatial relationship between the residence and daily public activities.
