兴文石林地质地貌景观的脆弱化趋势研究

Research on Ecological Vulnerability of Geological-Geomorphological Landscape of Stone Forest in Xingwen

兴文石林是喀斯特岩溶地质风景名胜区兴文石海的中心景区,喀斯特岩溶出地的生态环境具有一定脆弱特性,随着旅游业的不断发展,景区加大了开发力度,可能导致景区脆弱性的加剧,为了保证在旅游开发中能对景区重要的地质资源进行更好地保护,采用生态脆弱区评级指标及权重值评分法对兴文石林的10个主景点进行了研究,分析得出,兴文石林存在轻生态脆弱性、中生态脆弱性和强生态脆弱性三种梯度趋向,其中,脆弱性最强区域面积达到2平方公里的面积,这些区域分布在景区的边缘地带,因此,要实现旅游资源的可持续利用,必须对强生态脆弱性区域实行禁游和实行退耕还林等措施,以防止脆弱区域的扩大和脆弱性加剧。

Xingwen Stone - Forest is the central scenic sport of Xingwen Stone - Sea, a famous karst geological scenic area. As karst eeulogical environment is fairly frangible, the constant development of tourism may aggravate the frangibility . For better protecting important geological resources of the scenic area, research has been carried out on 10 main scenic sports of stone forest. On analysis, it gives the result that the area with high - level frangibility is up to 2 square kilometers, which are distributed on the borderlands of the scenic area. Therefore, for the realization of sustainable utilization of tourism resources, measures, including forbidding traveling in highly frangible ecological area and quitting cultivation and returning to forest, must be taken to prevent the expansion of frangible zone and the increase of frangibility.
