摘　　要：以地质遗迹空间分布为导向,综合考虑地质遗迹景观质量、当地经济发展需求等因素,对海南省万宁市小海—东山岭省级地质公园进行定界研究。地质遗迹的集中性和质量等级是划定地质公园界线范围的前提和基础,在现场踏勘的基础上,评定地质遗迹景观质量等级,定位地质遗迹资源的地理位置,运用ArcGIS 10.0对地质遗迹点的空间分布模式及特征进行分析。区域内地质遗迹的分布呈聚集模式,特别在650 m的观测距离内,地质遗迹聚集态势愈发明显,继而以650 m为缓冲距离初步划定公园范围。进一步考虑当地经济发展需求,结合研究区域内其他规划,最终划定地质公园界线范围。The research on delimitation of the Xiaohai-Dongshanling geopark was oriented with geosites spatial distribution, comprehensive considering the geosites grade and local economic development needs and other factors. The concentration and grade of the geosites is the basis of the geopark delimitation. The geosites is evaluated and located based on field surveying. Then the spatial distribution patterns of geosites was worked out by ArcGIS soft- ware, the results reveal that the geosites distribution shows aggregation mode in the study area, especially within the 650m distance of the observation, aggregation trend of geosites is becoming increasingly apparent. So the paper gives the initial delimitation of geopark, further considering local economic development needs, combining with key projects in the study area, the final delimitation of the Xiaohai-Dongshanling geopark is deduced.
