【摘要】 为探究苏北平原地区农田林网景观美景度，以问卷调查为手段，利用美景度评价法(Scenic Beauty Estimation, SBE)对江苏省泰州市姜堰区示范点6种不同植被配置的农田林网进行了美景度评估。结果表明，苏北农田林网SBE值季相性明显，春季含有开花的桃树及樱花配置模式评分较高，秋季含有彩色树种落羽杉的配置模式SBE值较高。四季度的综合评分SBE值范围为-0.90—0.81,其中落羽杉+石楠景观美学价值最高；而女贞纯林模式SBE得分在0分以下，整体景观效果一般。对景观要素和SBE值的相关性分析及多元线性回归方程表明，影响农田林网美景度的主要景观要素为平均冠幅、平均树高及树种数。因此，考虑景观生态因素，在营造苏北农田林网时可以多采用2种树种配置种植模式，以及增加高大常绿树种的比例，提升其景观美景度。该研究扩大了SBE法的应用范围，将农田林网美景度量化更加客观地进行评判，为表征农田林网的景观质量提供了新的视角，也为其他地区农田林网景观设计提供参考。更多还原

【Abstract】 In order to explore the landscape beauty of the farmland forest network in northern Jiangsu Plain Region, Scenic Beauty Estimation(SBE) was used with 6 different vegetation configurations at the demonstration site in Taizhou City.The results showed that the SBE value of the farmland forest network in northern Jiangsu was obviously seasonal. The configuration mode with peach trees and cherry blossoms in spring had a high score, while the configuration mode with colored trees had a high SBE value in autumn. The comprehensive score of the four seasons to ranged from-0.90 to 0.81. Taxodium distichum+ Photinia serratifolia(Desf.) Kalkman model had the highest SBE value, while the SBE score of Ligustrum lucidum pure forest model was negative, indicating a relatively poor overall landscape effect.The correlation analysis and multiple linear regression equation between landscape elements and SBE showed that the number of average tree crown, average DBH and the number of tree species had the highest influence on the beauty degree of farmland forest network. Therefore, considering the landscape ecological factors in constructing the farmland forest network in northern Jiangsu, two tree species could be used to constract the planting mode, and the proportion of tall evergreen tree species could be increased.This study expands the application scope of SBE method, and quantifies the beauty of farmland forest network more objectively, which provides a new perspective for reflecting the landscape quality of farmland forest network, and also a reference for the landscape design of farmland forest network in other regions.更多还原
