摘　　要：建立和完善绿色农产品基地适宜性评价方法,提高评价结果的实用性和准确性,是实现农产品安全的根本保障。研究依据基地认证者、规划者、生产者3种评价主体实际需求,分别引入污染潜在风险指标和经济状况指标,建立面向不同评价主体需求的多种主导因子评价指标体系,并借助GIS的空间分析方法进行定量评价,最后以北京大兴区为例进行了案例分析研究。结果表明,基地与工矿企业距离、与居民地距离等潜在污染风险对基地适宜性限制大,且不同评价主体下建立不同指标体系使评价更具针对性,利用GIS功能可提高效率,评价结果可视化程度好,具有很强的实用性。The proposal and improvement of a method for suitability evaluation of green agricultural product bases can improve the practicability and accuracy of the evaluations.And thus,it is important to guarantee the safety of agricultural products.Based on the requirements of the authenticators,planners and producers,this paper proposed a multi-dominant indicator system which meeted different needs.GIS-based spatial analysis was adopted to quantitatively evaluate the suitability of an agricultural base.A case study was carried out in Daxing District of Beijing City.The results indicated that the distances from a base to some potential pollution sources like industrial or mining enterprises or settlements reduced greatly on the suitability of this base;and different systems of indices were required for different evaluation purposes.GIS-based method is highly practicable in the evaluation due to its high efficiency and visualization of its results.
