基于BIB-LCJ模型的湿地公园生态环境质量评价

Evaluation for Ecological Environment Quality in Wetland Park Based on BIB-LCJ Model

本文通过VR虚拟现实技术实时还原长荡湖湿地公园现实环境,建立25组场景实现侵入式体验。邀请208位不同背景的评价者接受场景体验并问卷调查,得到的结果利用BIB-LCJ法评价分析,可得到如下结论:四组少、青、中、老年龄段调查结果在Kendall相关性分析下,两两的相关系数在0.7以上,属中、高度相关,表明不同主体之间的审美敏感点较为一致;编号5、6、7及13、14、15虚拟场景生态环境质量评估结果 Z值构成了两大峰值区间[1.85,1.95]、[1.9,2],其余结果在1.75处波动;峰值段内的样本场景表明连续优雅的树群轮廓线、生态驳岸和丰富的景观色彩几类影响因子对生态环境给受访者带来的感受有着积极的正面影响。

Through VR virtual reality technology, the real environment of Changdang Lake Wetland Park was restored in real time, and 25 sets of scenes were established to realize intrusive experience. 208 evaluators from different backgrounds were invited to accept the scene experience and questionnaire survey. The results were evaluated and analyzed by BIB-LCJ method.The conclusions were as follows: According to Kendall’s correlation analysis, the correlation coefficients of the four age groups were above 0.7, which was moderate and highly correlated, indicating that the aesthetic sensitivity points of different subjects were relatively consistent. The Z values of visual quality evaluation results of virtual scenes numbered 5, 6, 7 and 13,14 and 15 constituted two peak intervals [1.85, 1.95], [1.9, 2], and the rest of the results fluctuate at 1.75.The sample scenes in the peak section showed that the continuous elegant tree group contour, ecological revetment and rich landscape color had positive effects on visual quality.
