The land has multiple functions , including the ecological functions, the productive functions, and the living functions. The productive functions and living functions are based on ecological functions, but have also an influence on the ecosystem. In order to bring into full play of all functions of the land, it is necessary to plan as a whole the important functions of land resources in an area. For that reason,, the functional zoning in land use is proposed with Jiaozhou City as an example. Thirteen indexes such as the population density, the per mu yield GDP, the proportions of irrigated land and urban land are selected. Eighteen towns (subdistrict administrative offices) under Jiaozhou′s jurisdiction are zoned by hierarchical clustering of SPSS software to obtain the system clustering. Considering inter-regional differences, ecological environment differences, economic development characteristics, geography and resources conditions and other factors in the land use structures, Jiaozhou City is divided into four major types of functional zones: (1) central town development zone, which accounts for 7.80% of the total area and 27.30% of the GDP of Jiaozhou City in 2008, is the core development zone; (2) eastern development construction zone, which lies by Jiaozhou Bay and Dagu River and accounts for 29.43% of the total area and 36.13% of the GDP of Jiaozhou City; (3) north protective zone of basic farmland, which has a larger area of irrigated land than the other three functional zones and accounts for 26.78% of the total area and 16.08% of the GDP of Jiaozhou City; (4) southern low hills environment protective zone, which has a larger area of forest land than the other three function zones and a fragile ecological environment and accounts for 35.9% of the total area and 20.49% of the GDP of Jiaozhou City. Accordingly, the control measures and utilization directions of the four functional zones are put forward, as the scientific basis of rational utilization of land resources. The functional zoning in land use will provide some guidance for regional land sustainable development.
