Assessment of the implementation of general land use planning based on GIS in Sihong County,Jiangsu

Overall land use planning of a certain region is the spatial and temporal arrangement and layout of land utilization types according to physical,economic and social conditions and regional requirements. More important is the strict implementation of planning text. Evaluations of implementation of general land use planning are an indispensable part of general land use planning and an important part of the planning implementation phase. Most of the current research has evaluated using the index system,but this does not reflect land use differences in space. In this paper the implementation effects of general land use planning were evaluated from spatial concordance during the implementation process,the spatial concordance of the implementation outcome,the shift of the barycenter of construction land and the layout of land use patterns by the spatial concordance model,the shift of barycenter model and the annular model with the aid of GIS software. Sihong County in Jiangsu was chosen as the study area for testing the applicability of the above-mentioned models and the models proved to be suitable tools in the assessment of enforcement effects of general land use planning. The evaluation models combine quantitative assessment and spatial analysis altogether and the results could be used in guiding the further actualization of general land use planning. Our study not only enriches the methodology of general land use planning evaluation but also provides constructive guidelines of better actualization of land use planning for local governments.
