摘　　要：根据京郊菜田的分布和土壤养分、土壤环境质量特点选择了监测点,按照各个指标对土壤质量的影响程度确定评价指标及其权重,并据此建立了无公害菜田土壤环境评价系统。系统采用分层体系结构,在目前基于J2EE架构开发Web应用的基础上,采用J2EE中的JSP,Servlet,JavaBean以及JDBC技术来构建该平台的基础组件框架,结合MVC结构的方式来构建Web应用系统,有效地提高了应用程序的可重用性、可维护性和可扩展性。根据过去3年的监测结果对于系统进行了初步应用,对各个监测点的菜田土壤环境质量进行了评价,表明该评价系统对菜田环境质量管理具有很好的指导意义。It is important for getting the information on the change of soil fertility and soil environment to understand soil productiv-ity and ensure vegetable safe production. Some surveying locations were set up in vegetable field in order to monitor the change of soil quality; meanwhile, an evaluating system was developed according to the affecting coefficient on soil quality. Multi-tiers struc-ture was selected in the design of advisory system program. A scheme of using J2EE technique to develop web applications is pre-sented following MVC pattern, which could improve the reutilization, maintenance, and expansibility of the evaluation system. Based on the monitoring data in different surveying locations in the last 3 years, the results showed that the evaluation system was very useful for the management of soil environment for vegetable production in Beijing suburb.
