基于eCognition影像解译技术的风景环境植被景观遥感量化研究 ——以云南鸡足山为例

世界遗产标准vii是UNESCO用以评价遗产地审美价值的重要准则,由标准iii演化而来,从文化与自然美的混合评价转向了仅对自然美学特征评价。选取以标准vii列入世界遗产名录的145处项目(1978—2017年),通过扎根理论及分析,总结其运用特征、演化趋势和动因考辨。研究发现：1)地区层面,不同地区运用标准vii所关注的审美价值具有差异,如非洲关注色彩美学,欧洲和北美强调风景特质组合,亚太地区重视强烈的自然文化关联、动态变化和组合关系,南美和加勒比地区注重审美体验;2)词频运用层面,标准vii在各地区的词频运用差异显著,各地区使用词频最高的为关于美的“形容词”,除欧洲之外,其余地区代表“之最”特点的词频次之;3)评价要点层面,欧洲和北美的风景特质评价具有很强的特点与范式。最后解析了标准vii运用趋势与18世纪以来的美学思想演变的内在联系;以期为标准vii的全球普世价值与地区价值认知以及标准vii后续研究提供依据。

Criterion vii is an important criterion for UNESCOto assess the heritage aesthetic value. Criterion vii is developedfrom criterion iii which transfers from assessing the aestheticto assessing both the nature and culture. The research analyzes145 world heritage sites which ever used Criterion vii fornomination. Through the grounded theory, this research analyzesthe application tendency of Criterion vii and explores the reasonof the application. Through the visualization digital technique,this research indicates that: 1) In terms of region, different regionsreveal different aesthetic characteristic. Africa focuses on thecolor characteristic, Europe and North America emphasizes thevision experience, Asia reflects the strong combination of naturaland cultural value, and South America pays more attention onaesthetic experience; 2) In terms of vocabulary application, thisresearch finds out the most commonly used high-frequency wordsand makes a vocabulary tree diagram; 3) In terms of the emphasisof usage of Criterion vii, it illustrates the assessment of landscapecharacters in Europe and North America. Finally, this researchsummarizes the relationship of Criterion vii and aesthetic valuessince 17 th century, and provides evidence for the further usage ofCriterion vii in the application of world heritage sites.
