“…Three factors, namely, tropical plant texture, undergrowth vegetation coverage and tropical sight control, were negatively correlated with the tropical beauty of the plant community, among which 'plant art composition' had the greatest correlation. After seven times of partial correlation coefficient analysis, the least relevant landscape evaluation factors were removed each time Fingerloos and Gehlen, 2019;Landová et al, 2018;Stubblefield et al, 2019). Finally, six factors such as 'tropical plant morphology', 'tropical plant texture', 'plant art composition', 'representative plant species richness', 'evergreen and deciduous ratio' and 'tropical light transmittance' were retained:…”
