无干扰分析极端温度对园林植物冻害的影响

Non-interference Analysis of Influence of Extreme Temperature on Freezing Injury in Garden Plants

针对传统方法易受干扰导致分析结果不准确的问题,提出唯象损伤理论,对园林植物在极端温度下的冻害影响进行无干扰分析;通过分析园林植物栽培的位置和植物冻害症状,进而划分冻害等级。在此基础上,分析园林内外温度与极端温度变化差异,在微观角度分析植物被冻害的唯象特征,以该特征为背景,研究模型出现的冻害现象;进而通过动态向量间接地反映植物细胞变化过程,获取细胞动弹模量与冻融循环之间的关系,构建唯象损伤冻害模型。实验表明:采用唯象损伤冻害模型分析的精准度最高可达94%,有效降低外界干扰,为实际园林植物冻害防护提供参考。

Traditional analysis methods are affected by external interference factors,which lead to inaccurate analysis results.Therefore,phenomenological damage theory is proposed to analyze the effects of freezing damage on garden plants under extreme temperature without interference,analyze the location of garden plant cultivation and the symptoms of plant freezing injury,and then divide the grade of freezing injury.On this basis,the analysis of landscape,both inside and outside temperature and extreme temperature differences,thus the microscopic angle,analyzing the characteristic of the plants were cold injury of phenomenological based on the characteristics of the background,the research model of frost damage phenomenon,then through dynamic vector indirectly reflect the change process plant cells,the cells loss modulus and freeze-thaw cycles,the relationship between the construction of phenomenological damage freezing injury model.The experimental results show that the accuracy of the phenomenological damage and freezing damage model can reach 94%,which effectively reduces the external interference and provides reference for the practical prevention of freezing damage of garden plants.
