在对矿业城市特殊性考虑的基础上确定评价指标体系,对平鲁区1995—2005年PRED系统发展状况进行分析,通过主成分分析法筛选出4个主成分。结果表明,平鲁区PRED系统整体呈可持续发展状态。其中,人口子系统表现为阶段上升后的下降,资源子系统整体呈缓慢上升趋势,环境子系统除在2000年与2003年出现轻微波动外,其余年间均呈上升趋势。平鲁区必须在总结过去发展经验的基础上,进一步走内涵挖潜之路,重视资源保护与土地复垦,充分发挥土地复垦在土地资源保护与生态补偿中的作用。
Based on the consideration of the particularity of the mining cities, the evaluation index system is determined, the development of PRED system in Pinglu District from 1995 to 2005 is analyzed, and four principal components are selected through principal component analysis. The results show that the overall PRED system in Pinglu District is in a sustainable state. Among them, the population subsystem showed a decline after the rise, the resource subsystem showed a slow upward trend, except for slight fluctuations in 2000 and 2003, the environmental subsystem showed an upward trend. On the basis of summing up the development experience of the past, Pinglu District must further take the road of tapping its potential, attach importance to resource protection and land reclamation, and give full play to the role of land reclamation in the protection of land resources and ecological compensation.
