胶州市土地利用功能分区研究

 土地资源是一个综合的功能整体，具有生态功能、生产功能和生活功能。其中，生态功能是基础，同时生产、生活功能又影响生态系统。为充分发挥土地资源系统的整体功能，有必要对整个区域土地资源的重要功能进行统筹研究，即可以采用土地利用功能分区的方法统筹安排土地的利用方向。选取人口密度、亩产GDP、水浇地比重、城市用地比重等13个指标作为评价指标，对胶州市所辖的18个乡镇（街道办）进行土地利用功能分区。利用SPSS软件的Hierarchical Clust功能，得到系统聚类结果，在充分考虑区域间土地利用结构差异、生态环境差异、经济发展特征、区位条件及资源条件等因素的基础上，对聚类分异的结果进行了修正。将胶州市分为中心城镇发展区、东部重点开发建设区、北部基本农田保护区、南部低山丘陵生态环境保护区，并且对四类功能分区提出调控措施及利用方向，为合理利用土地资源提供科学依据，有利于实现区域土地可持续发展。

Functional Zoning in Land Use of Jiaozhou City

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.
