Abstract: Ground surface habitat destruction by energy exploitation, goaf subsidence caused by underground mining, and pollutant discharge from energy and chemical enterprises are the main factors leading to the environment deterioration in energy source regions. However, in a larger scale, the mechanisms driving the interactions between the industrialization in mining area and the regional ecological pattern is rather complicated, and it is difficult to determine the spatiotemporal rhythm and scale synchronization. In this study, a rich energy region in Shaanxi under the background of ecological restoration was chosen as a case. Based on the DMSP/OLS and MODIS NDVI data, the spatiotemporal variation characteristics of the industrialization process and vegetation ecological risk pattern were analyzed, and the spatial variations of land use types, the decreasing trends of annual precipitation and runoff, and the frequency of earthquake occurrence were analyzed at different scales, aimed to explore the impacts of industrialization process on ecological risk. The results showed that whether the hypothesis that industrialization would directly increase the regional ecological pressure in mining area could be established was dependent on empirical perspective and scaling. Under the background of vegetation restoration, the role of industrialization on vegetation pattern could not appear at a larger scale analysis. Overall, the ecological environment in the energy rich region of northern Shaanxi was in a pattern of generally improved and partially deteriorated. The interaction mechanism of vegetation pattern and industrialization process was unidirectional and of asynchronization in time and space, and the small and large scale observational results were inconsistent. The industrialization process in smaller areas still strongly affected the local ecological security. It was suggested that the policy orientation of regional ecological environment construction should be considered to balance the whole and its partials.
