紫金山国家森林公园景观视觉评价

摘要

为科学构建森林公园景观视觉评价技术体系,合理开展森林公园景观视觉保护与建设活动.以紫金山国家森林公园为例,按主客观评价加权的方式,对15个主要景点进行景观视觉评价,主观层面基于SBE法评价,客观层面以地理数据为基础,基于GIS技术,选取视点、视线、视域及视觉敏感性4个方面多个评价因子定量评价,最后,将主观与客观评价进行等比例加权分析.结果表明,景点9的景观视觉条件最优,景点15的景观视觉条件最差.该评价体系在景观视觉资源的保护与开发中具全面性和可操作性,可为森林公园视觉景观资源的管理与提升提供科学依据.%In order to build a scientific system of landscape visual evaluation,and to guide the activities of landscape visual protection and construction in forest park,the visual resources of 15 scenic spots in Zijin Mountain National Forest Park were assessed objectively and subjectively.SBE method was adopted for subjective evaluation,while geographic data from GIS were used for objective evaluation,in which factors relative to four aspects were used to conduct quantitative analysis,including viewpoint,sight,visual field and visual sensitivity.Finally,the objective and subjective evaluation were analyzed by the equal proportional weighted way.The results showed that the visual resource of landscape S9 was the best,while,that of S15 was the worst.The evaluation system was more comprehensive and operational in the protection and development of the visual resources of landscape,and it would provide a scientific basis for the management and promotion of the visual resources of the forest park.
