摘  要：
以北京市房山区为研究区域,选用土壤肥力和土壤环境质量的8个指标,采用层次分析法(AHP)、负权重和模糊数学对北京房山区土壤质量进行综合评价,发现房山区土壤综合指数在0.247~0.996之间,其中燕山地区土壤综合指数最低(0.247),蒲洼乡的土壤综合指数最高(0.996)。根据耕地地力等级的划分范围,北京市房山区Ⅰ级占9%,Ⅱ级占23%,Ⅲ级占55%,Ⅳ级占14%,说明土壤质量总体处于中等水平。通过对比分析Ⅰ级和Ⅳ级指标含量,发现土壤综合指数高的区域具有土壤肥力指标高、土壤环境质量指标低、没有指标超标的特点,而土壤综合指数低的区域具有土壤肥力指标低、土壤环境质量指标高、至少有一个指标超过临界值的特点。

摘  要：
The research area located at Beijing Fangshan district,soil fertility and soil environment quality was taken as evaluating indicators which included soil organic matter, alkaline N,available P,available K,Cu,Pb,Cr,Cd. Comprehensive evaluation of soil quality was carried out by analytic hierarchy process,negative weights and fuzzy in Fangshan district of Beijing city,the results showed that the soil quality index was between 0.247 and 0.996,in which soil quality index of Yanshan area was the lowest of 0.247,soil quality index of Puwa town was the higest of 0.996. According to the classification cultivated land fertility range,Ⅰgrade accounted for 9%,Ⅱ grade accounted for 23%,Ⅲ grade 55%,Ⅳ grade 14%. Through comparative analysis it was found that areas of high soil quality index had high soil fertility,low soil environmental quality indicators,no indicators exceeded the threshold. Areas with low soil quality index had low soil fertility, soil environmental quality index was higher, and there was at least a characteristic index exceeded the threshold.
