摘　　要：评价农林复合系统及其农业生产管理对当地环境产生的影响,指标体系的确定是前提和关键。该文以陕西渭北旱塬农林复合系统为例,在广泛研究的基础上,构建了农林复合系统环境评价指标体系,该指标体系由环境污染状况指标、农副产品污染状况指标、社会经济效益指标、生态环境质量指标4部分构成,并运用该指标体系,采用多级模糊综合评判模型和改进的标准赋权与层次分析相结合的权重确定方法对当地农林复合系统的环境质量进行了评价,结果与实际情况吻合。In assessing the influence of agroforestry system and its agricultural production management on local environment, the establishment of assessment indicator system is the basic and key problem. Taking the agro-forestry systems in Weibei Upland, Shaaxi province, as a case, based on the sufficient study, the environmental assessment indicator system was established in this paper, which consists of four sections: the environmental contamination indicators, the agricultural products contamination indicators, social economical indicators and eco-environmental quality indicators. At the same time, using this assessment indicator system, the environmental quality of agroforestry systems was assessed by applying multilevel fuzzy synthetic evaluation model, analytical hierarchy process and improved standard weight deciding method, the assessment result is consistent with the reality.
