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。
Landscape ecological risk assessment can effectively optimize the regional landscape pattern and provide theoretical basis for risk prevention.Bibliometrics show that domestic research on ecological risk assessment of karst landscapes starts from four aspects,"research object","evaluation model","evaluation method"and"evaluation index".As a special karst body,travertine has rarely been studied on its ecological risk assessment.Beginning from the ecological risk assessment of karst landscape,based on the fuzzy mathematics comprehensive evaluation method and analytic hierarchy process,this work proposes to take surface travertine and surface water cycle as the main landscape,and gradually refine the main factors to form a multi-level comprehensive evaluation model.Carrying out the ecological risk assessment of travertine landscape is of great significance for reducing the disaster loss of travertine landscape and protecting its aesthetic value.
