Study on new construction land regulation in land use planning based on major function-oriented zoning

Land use planning lays the critical basis for land macro-control and land use regulation systems. Major function-oriented zoning planning locates state and local development directions and requirements in relation to the land use arrangement and structure in space. This in turn comprehensively promotes state or local economy and coordinates sustainable development. Based on function-oriented zoning strategies, the main function-oriented zoning index systems including the importance of eco-environment, support of social economy and land use strength were structured in this paper. The new construction land index distribution was suitable for the overall land use planning in the study area. The paper analyzed Lulong County of Hebei Province as a case study and used GIS (Geographical Information System) platform to evaluate new construction land area in different village/towns via weighted summation and “matris” with available data. Land development (D), use (U), harness (H) and protection (P) of land use were set different priorities, U-H-D-P, D-U-H-P, H-P-U-D, P-H-U-D, in which the weight of D were 0.256, 0.491, 0.148 and 0.104 respectively. And then new construction land area allocated to each village and town in the overall land use planning in Lulong County were calculated. Among the villages/towns, Liutiangezhuang, Lulong and Shimen were the important priority development towns with the most new construction land area as much as 230 hm² and more. Other villages and towns also attained the level of indexes needed for development of urban areas. The paper coordinated land use plan and major function-oriented zoning as the breakthrough point. Compared with traditional land use planning, the new planning (based on major function-oriented zoning) to some extent overcame the subjectivity of decision makers and comprehensively coordinated sustainable ideas. The paper provided methodological basis for index distribution of overall land use planning, promoted optimal allocation of regional land resources within program limits and ensured sustainable utilization of land resources.
