摘要
[目的]为了解句容市水稻土环境质量状况。[方法]采集句容市8个乡镇的水稻土样本进行分析,以期通过对句容市水稻土养分状况和稻田重金属污染状况的研究而探究出句容市水稻土环境质量状况。土壤养分调查选择氮、磷、有机质三类;而重金属则以铅为代表。[结果]句容市水稻土中N、P、有机质含量均处于土壤肥沃的养分水平,句容市水稻土铅含量在安全水平。[结论]句容水稻土中N、P和有机质含量丰富,而重金属铅含量在安全水平之上,因而句容水稻土的环境质量处于一种良性循环的状态。
[objective]In order to understand the paddy soil environment quality condition of Jurong City. [methods] acquisition Jurong City eight villages and towns of paddy soil samples were analyzed ,and hope to through the Jurong City paddy soil nutrient and rice fields of heavy metal pollution conditions research to explore the Jurong City paddy soil environment quality condition.Soil nutrient survey selection of nitrogen ,phosphorus and organic matter types;And heavy metals is represented by lead.[results] N, P and organic matter content in paddy soil in the fertile soil nutrient levels, Jurong City paddy soil lead levels in the security leveL[conclusion] the N, P and organic matter content in paddy soil is rich, while the heavy metal lead in the safety level, so that the environmental quality of paddy soil of Jurong is in a state of a virtuous cycle.
