摘要：采用固定样点全年拍摄的方式,对通州运河森林公园典型景观样点进行全年图像采集作为分析样本。从景观结构特征与季相特征2个层面梳理出14个景观特征要素,利用SBE(scenerybeauty estimation)方法及基于美景度与眼动指标逐步回归构建的SVE(scenery visual estimation)方法进行景观质量评价,并分析景观特征要素对景观质量的影响。结果表明:1)71.3%的SBE与67.8%的SVE样本为中高等级,全园总体景观质量良好,二者的评价均值都为0.137,但SBE(±0.501)比SVE(±0.224)具有更大的标准差,数据波动性更大,且SBE(R2=0.587)比SVE(R2=0.483)具有更高与景观特征要素逐步回归的线性模型拟合度,能够反映出更多的彩色、常绿、枯落等季相特征细节;2)乔灌草种植植物、常水面面积比例等结构特征要素,对景观质量具有显著影响,林水结合比单纯的林景景观质量高;3)常绿灌木、彩色乔木、落叶灌木、枯落草本、可见季相总面积比例等季相特征要素对景观质量具有显著影响,增加常绿灌木、彩色乔木在种植植物群落中的面积比例,减少落叶灌木、枯落草本在种植植物群落中的面积比例有利于提升景观质量。
Photos were taken from fixed points of typical sceneries in Tongzhou Canal Forest Park every month throughout a year,which were collected as analysis samples to evaluate the effects of plant structure and seasonal aspect on the landscape quality of the park.Fourteen landscape features were screened out from the two aspects:landscape structure characteristics and seasonal aspect characteristics.Scenery beauty estimation(SBE)and scenery visual estimation(SVE)that was derived from stepwise regression model of SBE and eye movement index were adopted to evaluate landscape quality of the park.The effects of landscape features on landscape quality were analyzed.The results showed that 1)71.3%of SBE and 67.8%of SVE samples were in the middle grade and high grade,and the overall landscape quality of the park was good.The averages of the two evaluations were the same as 0.137,but the standard deviation of SBE(±0.501)was larger than that of SVE(±0.224).The SBE method had larger data volatility,and SBE(R2=0.587)had a higher linear fit degree in stepwise regression with landscape feature elements than SVE(R2=0.483),which could reflect more details of seasonal aspect,such as color,evergreen and withering.2)The proportions of vegetation and normal water surface area had significant effects on landscape quality.The quality of forest landscape could be improved by the addition of waterscape.3)Features of seasonal aspect exhibited significant effects on landscape quality,such as evergreen shrubs,colored trees,deciduous shrubs,withered herbs,and the area of visible seasonal aspect.To increase the area proportion of evergreen shrubs and colored trees,and to reduce the proportions of deciduous shrub and herb were conducive to improve the landscape quality.
