| 中文摘要: |
| 为探明广州市农业面源污染特征，有针对性地采取合理的污染控制对策，运用等标污染负荷
法和GIS 技术，以地级市为单元，研究广州市种植业、养殖业、农村生活等农业面源污染来源化学需氧量
（COD）、总氮（TN）、总磷（TP）的负荷、特征以及污染源的敏感性评价。结果表明，2014 年广州市农业
面源污染物COD、TN 和TP 的排放量分别为605 564.60、21 235.41 和1 171.60 t，排放强度分别为814.54、
28.56 和1.58 kg/hm2；最主要污染源为畜禽养殖，其等标污染负荷比达74.37%；最主要污染物为COD，其等
标污染负荷比达52.78%；COD 排放强度最高的地区是黄埔区，最低为荔湾区，而TN 和TP 排放强度最高的
地区均为天河区，最低均为从化区；花都区、白云区、黄埔区和番禺区为整个广州市农业面源污染的高度敏
感区和优先控制区。 |
| 英文摘要: |
| In order to understand the characteristics of agricultural non-point source pollution（ANPSP）
and make reasonable pollutant control strategies in Guangzhou，taking prefecture city as basic unit，the equivalent
standard pollution load method were conducted to the discharge amount and regional difference of chemical oxygen
demand（COD），total nitrogen（TN） and total phosphorus（TP） from different types of agricultural non-point
source pollutions，including planting，breeding，rural life. And GIS technology was used to assess sensitivity of
pollution sources. The results showed that the COD，TN and TP loads of Guangzhou in 2014 were 605 564.60，
21 235.41 and 1 171.60 t，and emission intensities of these pollutants were 814.54，28.56 and 1.58 kg/hm2，
respectively. The primary pollution source was livestock breeding whose load ratio in equivalent standard reached
74.37%，and the primary pollutant was COD whose load ratio in equivalent standard reached 52.78%. The highest
emission intensity of COD occurred in Huangpu District，the lowest in Liwan District. The highest emission intensity
of TN and TP occurred in Tianhe District，the lowerst in Conghua District. The highest sensitive areas and priority
control areas were Huadu District，Baiyun District，Huangpu District and Panyu District for the whole Guangzhou. |
