摘要
基于内梅罗综合指数法对2021—2023年烟台市农村农业面源污染进行评价分析,烟台地区农村农业面源污染整体污染呈逐年显著加重的趋势,主要污染因子为总氮和硝酸盐氮。烟台市农村农业面源污染与区域内果树、农作物种植,农药化肥的过量使用息息相关,农村农业面源污染问题亟需引起重视。
This study utilized the Nemerow composite index method to assess and analyzethe agriculturalnon-point source pollution of Yantai City for the year of 2021 to 2023.The results indicated a consistent and substantial escalation in overall pollution levels,primarily attributed to total nitrogen and nitrate nitrogen.The issue of the agriculturalnon-point source pollution in Yantai City was intricately linked to the excessive usage of pesticides,fertilizers,as well as cultivation practices for fruit trees and crops within the region.Urgent attention was warranted to address this critical environmental concern.
