摘要
以四川省地质遗迹为研究对象,构建了以地质构造单元、深大断裂、地貌特征为主要因子的地质遗迹空间区划格局系统,将境内地质遗迹划分为3个地质遗迹大区、8个地质遗迹亚区以及26个地质遗迹小区,并在此基础上选取了20个具体评价因子,运用AHP法、模糊综合法及SPSS软件对该区划系统进行了定量评价。结果表明,龙门山、峨眉山—老君山2个小区为"好"级;茂汶—丹巴、贡嘎山、盆中、摩天岭、成都平原、德格—稻城、攀枝花、盆东、大凉山、川东南10个小区为"较好"级;盆南、米仓山、盐源、泸定—米易、理塘、马尔康、义墩、若尔盖、炉霍9个小区为"一般"级;雅江、大巴山、会东、盆北、降扎5个小区为"较差"级。
Based on geoheritages of Sichuan as the study object, the authors built the spatial pattern system of geoheritages taking geo-structure unit, deep fractures and landform as its main elements, and divided geo-sites of the study area into three geo-site areas, eight geo-site sub-areas and twenty-six small geo-site units. Based on the above division, twenty specific evaluation factors were selected.The spatial pattern system was quantitatively conducted by exerting AHP, fuzzy synthesis and SPSS software. It was concluded that Longmenshan and Emeishan-laojunshan were identified to be the best units; while Maowen-Danba, Gonggashan, Middle Basin, Motianling, Chengdu Plain, Dege-Daocheng, Panzhihua, East Basin, Daliangshan and Southeast Sichuan belonged to good units; In addition, South Basin, Micangshan, Yanyuan, Luding-Miyi, Litang, Maerkang, Yidun, Ruoergai and Luhuo were regarded to be normal units; Finally, Yajiang, Dabashan, Huidong, North Basin and Jiangzha were regarded to be poor units.
