| 摘 要： | 景观生态风险评价能够有效地对区域景观格局进行优化并为风险防范提供理论基础。文献计量学分析表明，国内岩溶景观生态风险评价研究主要从“研究对象”、“评价模型”、“评价方法”和“评价指标”4个方面分析；而钙华作为特殊的岩溶体，目前对它的生态风险评价几乎未开展。文章从岩溶景观生态风险评价入手，基于模糊数学综合评判法和层次分析法，提出以地表钙华体与地表水循环作为景观主体，并对主体因素逐步细化，形成多层次综合评价模型，展开对雪宝顶流域钙华景观的生态风险评价。

| Abstract: | In order to investigate the geological characteristics of karst,fissures and underground currents in Jiuzhaigou valley travertine scenic spot after the earthquake, enrich the non-destructive detection technology of karst cave in travertine scenic area, and discuss the reliability of multi-geophysical exploration technology in porous and loose travertine area,in this paper,the non-desctructive detection technology combining Ground Penetrating Radar (GPR) and high-density resistivity method was used to carry out field survey and nondestructive detection test in the specific area of the sparkling lake in Jiuzhaigou valley particularly.Comparing the two kinds of non-destructive detection results with three groups of exploration data of the exposed geological section in the survey area,it was found that the combination of high-density resistivity method and ground penetrating radar method can complement each other ,support each other,and especially show a high degree of recognition for the detection target when solving the problems of shallow karst,underground current and fracture in the travertine area. The non-destructive detection data of the two methods are highly consistent with the geological characteristics of the exposed section after the earthquake, indicating the true reliability of the two non-destructive detection technology data under the condition of porous and loose media,as well as solving the doubts and difficulties of multi-physical exploration technology in the construction of porous and loose media areas,which is of great significance for enriching the field of engineering geophysical exploration technology. |
