基于投影寻踪模型的邕宁红心火龙果气候品质评定方法研究

Study on the method of climate quality certification of Yongning red dragon fruit based on projection pursuit model

为提升邕宁红心火龙果气候品质评定模型的精度和稳定性,基于立地条件、生长气象条件、生产管理条件、火龙果品质等数据,构建了一种基于投影寻踪模型的气候品质评定模型,并对邕宁区蒲庙镇联团村的红心火龙果进行了气候品质评定。结果表明,与传统经验公式对比,基于投影寻踪模型的邕宁红心火龙果气候品质评定模型的绝对误差缩小了11.9倍和20.0倍,有效减小了主观经验带来的评定误差,显著提高了气候品质评定精度。

To improve the accuracy and stability of the climate quality assessment model of the Yongning red dragon fruit,a climate quality certification model of the Yongning red dragon fruit based on the projection pursuit model was built with data from the site conditions,growing meteorological conditions,production management conditions,and dragon fruit quality,which was used to certify the climate quality of red dragon fruit in Liantuan village,Pumiao town,Yongning district.The results showed that,compared with the traditional empirical formula,the absolute error of the Yongning red dragon fruit climate quality certification model based on the projection pursuit model could be reduced by 11.9 and 20.0 times,respectively,effectively reducing the assessment error brought by the subjective experience and significantly improving the accuracy of climate quality certification.
