At the beginning of the construction of the city，Shenzhen attaches great importance to the urban planning work. In the past twenty years of the city，the three trilogy of “formulating the overall planning of the city-formulating planning guidelines-making urban planning legislation” has completed the process of urban planning from focusing on technology to the rule of law. At present，a relatively perfect urban planning legislation system，a scientific urban planning approval mechanism and a strict urban planning law enforcement system have been established. Urban planning not only guarantees the needs of urban construction and economic and social development，but also persists in the bottom line of public interest and ensures ecological balance. At present，the shortage of land resources in Shenzhen，the urban planning work is facing the new situation of “going to the sky and the earth”，“land and sea planning” and “reconstructing the old area”. It is necessary to strengthen the legal system，improve the system of the urban planning committee，enhance the public participation，and make a strict legal map revision.
