| 摘 要： | 对重庆市24个区县(市)农业环境质量的研究结果表明,农业环境污染表现出较为明显的区域性和局部性,城郊区污染较重,近、远郊区环境质量良好,但存在局部污染。城郊区土壤出现一定程度的Cd超标,农灌水水质良好,除近郊区一个水样Hg超标外,其他水样污染物浓度均远低于国家标准。城郊区农区大气环境质量相对较差,SO2、NOx、TSP存在一定程度的超标。针对重庆市农业环境污染现状,在农业生产布局上应树立保护治理城郊和重点发展近、远郊的指导思想,促进全市农业结构调整和无公害农产品快速健康发展。

| Abstract: | To compare agricultural resources and environmental quality in Chongqing region,we collected and analyzed dozens of soil,air and water samples taken from 24 counties of Chongqing,It was showed that pollution of environment at present exhibited the more obvious in some regions and partly in this city,i.e.pollution is more serious in the suburban area,but is better quantity in near far the suburban area.We found that Cd contents in some soil samples in the city suburban area were higher than the national standard.In addition,irrigation water is good.The contents of Hg,Cd,Pb,As,Cr6 in all samples were much lower than the national standard exception of Hg in just one sample.However,atmosphere quantity in Chongqing city suburban area was bad,the contents of SO2,NOx,TSP in some area samples in Chongqing city suburban area were higher than the national standard.Aiming at the environment present of agriculture pollution in the city,layout for the agriculture produce of the whole city should make use of this kind of resources environment advantage well,set up the thought of protection and management the city suburb,stress development the suburb and the far suburb,promote the whole city agriculture structure to adjust and have non-environmental pollution agriculture food develops quickly and healthily. |
