| 摘 要： | 采用野外采样和室内分析,试验结果表明,酸雨对重庆区域农业生态系统影响不明显,菜地土壤有一定酸化趋势.农田大气中酸雨的主要因子SO2、NOx具有显著正相关,协同作用明显,但分布无明显规律性.农田灌溉水呈中性至微碱性,江水碱性明显.中性的灌溉水对土壤酸化有正面作用,碱性的灌溉水能阻止土壤酸化.不同种植类型土壤酸碱度差异明显,茶叶土壤为酸性,水果土壤则以碱性为主,因此可根据不同作物对土壤酸碱的喜好,调整种植品种和区域. |

| Abstract: | By collecting samples outdoor and analysis indoor,these results display that this phenomena that acid rain influence on the agricultural ecosystem is not very obvious in chongqing,but there is a serious trend on vegetable soil.Main factors of acid rain(SO_2,NO_X) have obvious positive relativity,and cooperating action is very obvious,but the distribution has not obvious rule.Farmland's irrigation water appear neuter to tiny alkalescence,and the river appear obvious alkalinity.Neuter irrigation water acceler... |
