摘要

针对传统评价方法中存在的旅游地生态健康评价准确率低等问题,提出了一种基于梯度增强决策树的旅游地生态健康评价方法。设计了基于无人机低空遥感的旅游景区数据采集框架,构建了旅游景区生态健康评价指标体系,采用信息熵法和层次分析法确定组合权重。利用梯度增强决策树算法计算旅游景区生态健康状况,利用多支持向量机构建多分类器实现旅游景区生态健康评价。实验结果表明,本文方法的平均数据采集时间为0.76 s,指标权重计算错误率在-1% ~ 2%之间,平均评价准确率为97.2%。

An ecological health evaluation of tourist attractions based on gradient boosting decision tree
In order to overcome many problems existing in traditional evaluation methods, such as the low accuracy of the evaluation of ecological health of tourist attractions, an ecological health evaluation method of tourist attractions based on gradient boosting decision tree was proposed. The data collection framework of tourist attractions based on UAV low-altitude remote sensing is designed, the ecological health evaluation index system of tourist attractions is constructed, and information entropy and analytic hierarchy process were used to determine the combination weight. The gradient boosting decision tree algorithm is used to calculate the ecological health of tourist attractions, and multiple support vector machines are used to construct multi-classifiers to achieve ecological health evaluation. The experimental results show that the average data acquisition time of the method in this paper is 0.76 s, the error rate of the index weight calculation is between -1% and 2%, and the average evaluation accuracy rate is 97.2%.
