Good planning and order of space is to help the country's ability to govern and modernize the governance system, improve the level of space management and management, and promote the construction of ecological civilization and an important new urbanization initiative. The main supporting theory of spatial planning is: system theory, sustainable development theory, planning coordination theory and government governance theory. There is an obstacle in the six areas: the lack of a reasonable planning hierarchy, the lack of good departmental coordination mechanisms, the lack of a unified base platform, the lack of effective bottom line settings, the lack of scientific chassis planning methods, the lack of clear Legal system. We should build a unified spatial planning from six aspects: planning system, planning technology, planning and protection, and establish a "1 + X" spatial planning system based on existing planning. With the lead of the government, the establishment of the space planning committee ; To the land data as the basis, a clear spatial planning "base"; "three lines delimit" as the core, clear space planning "bottom line"; flexible planning and comprehensive land consolidation as the starting point, clear space planning "chassis" For the purpose of the country, and improve the spatial planning of the relevant legal protection.
