Analysis of Damage Factors and Damage Level of Recipient Plants in Agricultural Environmental Damage Appraisal
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.
