基于地质遗迹资源保护利用价值的保护区划分——以云南盐津乌蒙峡谷地质公园为例

地质遗迹资源保护利用价值是合理划分保护区的基础.本文以盐津乌蒙峡谷地质公园地质遗迹资源为例,从地质遗迹资源利用性和脆弱性两个方面构建地质遗迹资源保护利用价值评价指标体系,运用层次分析法确定地质遗迹资源保护利用价值评价因子权重.采用专家咨询法建立地质遗迹资源保护等级划分标准.利用菲什拜因-罗森伯格模型对盐津地质公园典型地质遗迹资源进行保护利用价值评价并划分保护等级.根据保护利用价值评价结果,利用Sufer9.0软件制作地质遗迹资源保护利用等值线图,结合地质遗迹资源保护的便利性与地方相关规划的协调性,绘制出盐津乌蒙峡谷地质公园地质遗迹资源保护分区图,结果为:盐津乌蒙峡谷地质公园特级保护区面积0.06 km^2,一级保护区面积11.74 km^2,二级保护区面积23.47 km^2,三级保护区面积75.07 km^2.

DIVISION OF NATURE RESERVES BASED ON CONSERVATION AND UTILIZATION VALUE OF GEOHERITAGES: A Case Study of Yanjin Wumeng Canyon Geopark in Yunnan Province

The conservation and utilization value of geoheritage resources is the basis for reasonable division of nature reserves. Taking the geoheritages in Wumeng Canyon Geopark, Yanjin County, Yunnan Province for example, the evaluation index system of conservation and utilization value is constructed from the two aspects of utility and vulnerability of geological heritage resources. The analytic hierarchy process(AHP) is adopted to determine the evaluation factor weight of conservation and utilization value. The expert consultation method is used to establish the classification standards of conservation grade. The Fishbein-Rosenberg model is applied to evaluate the conservation and utilization value of typical geoheritages in Yanjin Geopark and classify the conservation grade. According to the evaluation results, the contour map for conservation and utilization of geoheritage resources is made by Sufer9.0 software. Combined with the convenience of geoheritage conservation and coordination of local planning, the zoning map of Yanjin Wumeng Canyon Geopark is plotted as:super-grade conservation zone of 0.06 km², first-grade conservation zone of 11.74 km², second-grade conservation zone of 23.47 km² and third-grade conservation zone of 75.07 km².
