摘要：以珠海市淇澳岛红树林为评价对象,共收集32个具有代表性样地的近景景观图片和对应植物群落的相关资料,采用美景度评价法(SBE)获得公众对每个林分景观的美景度值,然后利用多元化理论模型I建立美景度与景观要素之间的回归关系。建模结果显示:影响红树林近景景观的主要因子有6个,即林分郁闭度、树干形态、树种组成、树干排列、林下层总盖度、平均林下层高度。得到淇澳岛红树林美景度与这6个因子间的线性模型,其复相关系数为0.759,F检验结果显著(P=0.019<0.05)。分析表明:树干通直、树干自由式排列有利于提高景观的美景度;林分郁闭度、树种组成、林下层总盖度过高或过低均会给景观美学质量带来负面影响。针对这些景观要素的特征提出了红树林景观营造的优化技术。
Taking the mangroves on Qi＇ ao Island in Zhuhai as the evaluation object, we collected 32 representative photos of near-view landscape and related information of mangrove communities. The scenic beauty values of each forest landscape were acquired by scenic beauty estimation method, and the relationship models of scenic beauty values and landscape elements were established by using multiple mathematical model. The main factors affecting the near-view landscape quality of mangrove were the forest canopy density, trunk form, species composition, arrangement of trunk, and the average of understory height. The multiple correlation coefficient of the model was 0.759 with significance by F test （P= 0.019〈0.05）. The straight trunk and its free arrangement were conducive to improve the scenic beauty, while the super-high or low forest canopy density, species composition and undergrowth coverage produced negative influence to the quality of landscape aes- thetics. According to the characteristic of above landscape elements, we put forward several management measures for the structure optimization.
