摘要: 准确了解区域人类建设扩张动态对于评估生态环境和社会影响不可或缺。基于DMSP/OLS、Landsat等多源遥感数据,采用阈值分割法提取2000—2013年攀西矿区的人类建设活动范围,并结合分形理论研究其动态变化特征,最后采用回归分析法研究其影响因素。结果表明,灯光遥感数据能够较好地提取人类建设活动范围,且分形维数总体呈现出先增加后稳定的变化趋势;灯光遥感数据的像元亮度与人口数量、矿山开采面积及经济等影响因素具有不同程度的相关性。研究结果将为优化土地利用模式,制定人口、经济等政策提供科学依据。

Abstract: It is necessary to know the dynamic of human construction expansion to assess the ecological environment and social impact. Based on the multi-source remote sensing data such as DMSP/OlS, Landsat, and other remote sensing data, the threshold segmentation method is used to extract the range of human construction activities in Panxi mining area from 2000 to 2013, and study its dynamic characteristics with fractal theory, finally, the regression analysis method is used to study the influencing factors. The results show that the light remote sensing data can extract the range of human construction activity well, its fractal dimension shows the change trend of increasing first and then stabilizing The Pixel brightness of the light data is correlated with the population quantity, mining area and economy, etc. The research results will provide a scientific basis for the optimization of land use patterns and the formulation of policies such as population and economy.

Key words: light remote sensing data, fractal theory, correlation analysis, Panxi mining area
