龙门山国家地质公园天台山风景游憩林空间结构分析与美景度评价

摘要

In this paper, three factors of neighborhood pattern, neighborhood comparison and species segregation were taken to describe the spatial structure of a typical scenic and recreational forest in Longmenshan National Ceopark of Sichuan Province. The SBE method was used to estimate the forest in terms of esthetics. A correlation model was built up by multiple regression technologies. The results showed that that there was obvious effect of neighborhood comparison and species segregation on scenic beauty estimation in the study area. This study provided a scientific basis for forest management by integrating ecological factors and aesthetic factors.%首先从空间结构出发,用角尺度、大小比数、树种分隔程度的空间测度指数3个参数来表述四川省龙门山国家地质公园内天台山风景游憩林的空间结构；然后从美学角度出发,用美景度评判法评价该处的森林景观质量,并提出把空间结构参数引入森林景观评价模型中,分析空间结构与美景度的相互关系.分析结果表明:在本研究区域内,空间结构的大小比数和角尺度2个参数对美景度都有显著影响.研究结果从生态与美学角度为科学经营森林提供建议与理论依据.
