摘要

The great changes in quantity and distribution of industry land of Tangshan city have taken place with the industrial boosting and shifting of Beijing-Tianjin district, especially the industry transferring toward coastal areas in Hebei Province. Study on the industrial land distribution, spatial pattern and expanding mode will help to establish rational land use planning and control the industrial land scale. RS and GIS were integrated to detect land use change and reveal the increase origin of industry land between 1993 and 2003. The indicators of barycenters transformation and landscape index were computed to present the spatial extension of industrial land in Tangshan city. The result shows that the scale of industrial land increased continuously from 6954.6 hm~2 to 8177.6 hm~2 by cultivated land transformation. The structure barycenter of industrial land moved 0.68 km westward and 0.24 km northward respectively. With industrial land patch increasing from 108 to 131, fractal dimensions and broken degree increased from 1.049 to 1.058 in ten years, and average patch area decreased from 62.82 hm~2 to 55.61 hm~2. Finally an industrial land spatial distribution mode was put forward based on the development stage and industrialization levels in Tangshan city.
