Abstract: By constructing the regional function evaluation index system of township units and using ArcGIS natural break point classification method and spatial autocorrelation method, this paper analyzes the spatial pattern characteristics of agricultural production, non-agricultural production, social security, ecology and tourism of 129 township units in Linyi City, Shandong Province, and quantitatively identifies the dominant function types of each township. Combined with the leading function, Linyi City is divided into three types of composite districts, and the planning strategy of regional function enhancement in different composite districts is put forward. The results show that: (1) The spatial pattern differences and spatial agglomeration characteristics of rural units in Linyi are obvious. (2) The types of regional functions of township units can be divided into eight types, among which social security and agricultural production-social security dominate the number of units. (3) The central region should reserve some space for industrial development and population agglomeration in combination with the overall land consolidation. The southern region should promote the large-scale operation of agricultural production and guide the moderate gathering of residents. The northern region should control the intensity of development and strengthen regional ecological conservation and tourism service functions.
