沂蒙山地质公园地质遗迹资源特征及定量评价

保护地质遗迹是建立地质公园的宗旨之一,地质遗迹评价是地质公园规划和保护地质遗迹的重要基础。在全面调查沂蒙山地质公园地质遗迹的基础上,深入分析了地质遗迹的重要特征,将公园内地质遗迹分为6大类、11类、12亚类。对地质遗迹定量评价方法进行了创新,增加了当地居民和游客的评价因子,并充分考虑了各评价因子的权重,从而使评价结果更客观准确。结果显示沂蒙山地质公园内地质遗迹类型多样,资源丰富,且均具有典型性、稀有性和自然完整性等特征,其中世界级地质遗迹4处,国家级地质遗迹5处。泰山岩群、新太古代的多期侵入岩体、金伯利岩型原生金刚石矿和岱崮地貌是沂蒙山地质公园内最重要的地质遗迹,其中大部分在科学研究中具有国内和国际意义。研究结果对于沂蒙山地质公园内地质遗迹的保护以及当地旅游事业的发展都具有十分重要的意义,对申报和创建沂蒙山世界地质公园也有一定的指导作用。
