Abstract: Agricultural environmental damage appraisal is an important part of ecological environment damage appraisal. However, due to its wide appraisal range, multiple influencing factors and high technical requirements for personnel, the development of agricultural environmental damage appraisal has relatively lagged behind the development of the whole environmental damage appraisal in our country. Based on the analysis of possible non-pollution damage-causing factors (eg. disease, pest, pesticide and fertilizer) and common pollution factors (eg. heavy metals, soil salinization, atmospheric dust, microplastics and other new pollutants) in the appraisal of agricultural environmental damage, this paper systematically introduced the identification methods of non-pollution damage-causing factors and analyzed the influence of their concentration changes on the growth of agricultural plants. In the analysis of the pollution factors, in addition to the influence of pollutant concentration changes on the degree of plant damage, the descriptive indicators of the damage degree of agricultural plants caused by different pollutants were also summarized. This paper aims at providing some scientific references for the development of agricultural environment damage appraisal and promoting the formulation of relevant system and norms, so as to ultimately realize the effective protection of agro-ecological environment.

摘要： 农业环境损害鉴定作为生态环境损害鉴定的重要组成部分，由于其鉴定内容涉及领域广、过程影响因素多、人员专业技术要求高，已成为制约我国环境损害鉴定领域发展的要素之一。通过立足农业生态环境损害鉴定中可能出现的非污染致害因素（如病害、虫害、药害和肥害）和较为常见的污染因素（如重金属、土壤盐碱化、大气粉尘和微塑料等新污染物），系统分析了非污染致害因素的识别方法及其浓度变化对农业植物生长的影响，而在污染因素的判别分析中，则在关注污染物浓度变化对植物损害程度影响的同时，也概括总结了不同类型污染物对农业植物损害程度的描述性指标，以期为农业环境损害鉴定评估工作的开展及相关制度规范的制定和完善提供科学参考，实现对农业生态环境的有效保护。
