桂西地区地质遗迹与民族文化资源的空间关系及成因机理

作为民族地区自然要素与人文要素的核心内容,地质遗迹和民族文化资源存在密切的空间关联和相互作用关系,定量研究两者的空间关系,是揭示民族地区人与自然关系及其成因机理的重要途径。本文从数量空间关系、质量空间关系和空间耦合关系3个方面,提出普适性的地质遗迹与民族文化资源空间关系定量研究方案,并以两类资源优势突出的桂西地区为典型区域展开研究。结果表明：桂西地区地质遗迹与民族文化资源的数量空间关联指数R值为0.478,其显著性检验显示两者之间数量空间关联密切;耦合协调度CI值越高表明地质遗迹与民族文化资源的质量空间关系越密切,桂西地区平均CI值为0.95,达到优质协调等级,表明两者之间具有很高的质量空间关联;耦合型资源评价值D越高表明地质遗迹与民族文化资源空间耦合关系越密切,桂西地区平均D值为1.04,靖西、平果、南丹、宜州等12县（市、区）D值较高,田林、田东、右江等部分县（市、区）D值较低,表明两者之间空间耦合关系总体密切但分布不均衡。地质遗迹与民族文化资源密切空间关系的成因机理,为始终同步进行并贯穿于民族地区人与自然关系各个方面的两者间的相互影响和作用所阐释,地质遗迹及其自然环境构成影响和制约民族文化产生、发展与演变的“地学基因”,而民族文化资源则是体现各民族对地质遗迹及其自然环境的选择与适应能力的创造物。

Spatial relationship and formation mechanism of geological relics and ethnic cultural resources in western Guangxi,China

Taking western Guangxi as a typical study area, the paper proposed a universal quantitative study scheme of spatial relationships between geological relics and ethnic cultural resources from the aspects of quantity spatial relationship, quality spatial relationship and spatial coupling relationship. The results show that the quantitative spatial correlation index value R between geological relics and ethnic cultural resources in western Guangxi is 0.478, the close quantity spatial relationship is found to be distinct based on significance testing. The higher the coupling degree value CI is, the closer the quality spatial relationship between geological relics and ethnic cultural resources is; The average CI of western Guangxi is 0.95 to achieve quality level, indicating the close quality spatial relationship; The higher the evaluation value of coupling resources D is, the closer the spatial coupling relationship between geological relics and ethnic cultural resources is. The average D of western Guangxi is 1.04, which indicates a great comprehensive level of the spatial coupling relationship but an unevenly distribution pattern. The D value is high in 12 counties including Jingxi, Pingguo, Nandan and Yizhou, while it is low in counties including Tianlin, Tiandong and Youjiang. The formation mechanism of the close spatial relationship between geological relics and ethnic cultural resources is illuminated by the synchronic and ever-existing interaction and influence of each other in ethnic areas, and geological relics with natural environment form the geography genes that influence and restrict the production, development and evolution of ethnic culture, while ethnic culture is the product that reflects the selection and adaptation of capability of nationalities to varied geological relics with natural environment.
