摘要
绥阳地质公园,位于贵州高原北部,园区内白云岩喀斯特景观总体可概括为洞穴、高峰丛洼(谷)地、丘陵、峡谷、坡立谷、象形山、天坑、石柱峰、水文遗迹等9大类,它们以中上寒武统娄山关组及下奥陶统桐梓组的白云岩地层为物质基础,有序、集中分布于双河洞、温泉、让水、金钟山等四片以金钟山至让水的分水岭为天然屏障,且相对独立的白云岩区域内,但四片区域相互之间却又以芙蓉江及其支流为连接纽带而紧密相连,共同构成一个以目前亚洲最长洞穴及全球最长白云岩洞穴为核心,峰丛、峡谷、天坑、温泉、地表河、坡立谷等为重要补充,形态优美、珍稀、雄伟、典型,且类型齐全的白云岩喀斯特景观系统。同时在对公园白云岩景观特征及区域地质背景进行分析和研究的基础上,系统研究和探讨了绥阳白云岩喀斯特"一岭两制"式的分异演化过程,并认为它是一个能充分展现白云岩喀斯特复杂演化过程和规律的典型代表地,是全球白云岩喀斯特地貌演化的杰出范例。
Suiyang Geopark is located in the north of Guizhou Plateau. The dolomite karst landscapes in the Geopark are generally classified into nine categories： cave, high fengcong-depression, hill, gorge, polje, pictographic mountain, tiankeng, pillar-like peak, and hydrological heritage. All of them are developed in the dolomite strata dominated by the Middle–Upper Cambrian Loushanguan Formation and the lower Ordovician Tongzhi Formation, and are distributed orderly and intensively in four dolomite areas, i.e., Shuanghe Cave, Weiquan, Rangshui, and Jinzhong Mountain, which are relatively independent dolomite areas that take the watershed ranging from Jinzhong Mountain to Rangshui as natural barriers physically, and are also closely linked with each other through Furong River and its branches. These geoheritages constitute a majestic, typical, beautiful and precious dolomite karst landscape system with the longest cave in Asia and the longest dolomite cave in the world as its core, and the peak cluster, gorge, Tiankeng, hotspring, river and polje as important complements. Based on the analysis and investigation of the characteristics of the dolomite karst landscapes and the regional background of the landscape formation in this geopark, the authors systematically studied and discussed the differentiation and evolution of ＂One Watershed Two Systems＂ of Suiyang dolomite karst, and hold that it is the typical representative place that could fully display the complicated evolutionary processes and regularity of dolomite karst and is the most outstanding case of global dolomite karst evolution.
