摘　　要：以宝钢工业区主厂区车间防护绿地为研究对象,于2007年6月下旬起对绿地结构进行全面调查,选取3种典型的绿地结构模式(乔木、大乔+灌木、小乔+灌木),建立包括生态效益2个方面、6个指标的评价体系,进行绿地效益评价。主要采用主成分分析和综合评判的方法,对其综合环境效益进行评价研究,并在此基础上进行选优,以便探索综合效益最优的配置模式,为钢铁企业绿化提供科学参考。研究结果表明:车间防护绿地的大乔+灌木模式环境效益最好,综合评价值为0.8257;环境效益以复层配置模式的绿地为佳,单一的配置模式较差;绿地的环境效益与其植被的配置模式直接相关。Greening area benefit evaluation is the base of greening areas construction. The greening areas for environmental protection of Baosteel general workshops were studied based on the complete investigation of the greening area structures and three typical plant configuration patterns of arbor, tall arbor ＋ shrub, and small arbor ＋ shrub were chosen. An evaluation system including 6 indexes distributed to two aspects of the ecological benefits was established. In order to provide the scientific adviees for the landscaping of the steel corporation, the comprehensive benefits were explored using the methods of primary component analysis and the comprehensive assessment. The results show that the ecological benefit of arbor ＋ shrub was the best with the evaluation value was 0. 8257. The multiple layer configuration pattern of greening areas had better environmental benefit, and the single configuration pattern had low environmental benefit. The ecological environment benefit of the greening areas was related directly to its plant configuration pattern.
