锥状喀斯特区溶洞景观特征及其旅游资源评价

锥状喀斯特是湿热带地区重要的喀斯特地貌景观类型和高品位的旅游资源.发育在锥状喀斯特地区的溶洞既是锥状喀斯特地貌景观的重要组成部分,也是发展旅游不可替代的景观资源.本文从这一认识出发,首先揭示了锥状喀斯特及溶洞发育的四大特征:(1)溶洞成因类型多样;(2)是深、长、大洞的主要发育区;(3)不同锥状喀斯特发育阶段,洞穴类型组合不同;(4)能形成溶蚀、沉积形态丰富、造型奇特、美学价值很高的溶洞景观集群.在此基础上,进行了初步的旅游价值评价,指出在旅游开发中具有三大资源优势:(1)洞穴资源具有多功能性(科研、探险、观光旅游、生态旅游、医疗等).(2)构成独特的高品位峰林-溶洞(地面、地下)综合景观类型.(3)景观资源的高度互补性可提高旅游景观内涵的丰度和旅游经济效益.
