| 摘 要： | 采用盆栽试验进行砷污染土壤修复研究,根据4种不同改良剂对土壤修复的效果来评价改良剂的优劣,确定土壤修复最优模式.并采用灰色关联分析和聚类分析评价方法,以生菜生物量、农艺性状和生菜砷吸收量等为指标,对污染土壤修复贡献值进行定量分析和聚类评价.结果表明,磷石膏(20 g/kg)处理关联度值r=0.824最大,聚类分析为最优,是修复砷污染土壤的最优改良剂处理.

| Abstract: | Based on the remediation effects of soil, four different amendments are studied by the pot experi-ment of arsenic contaminated soil to determine the optimal remediation model. The soil remediation contribu-tion value for different amendments is evaluated by grey relevant analysis and cluster analysis. The evalua-tion indexes include biomass yield, agronomic characters, and absorption amount of arsenic of lettuce. Re-sults show that the phosphorus plaster treatment(20g/kg), with greatest grey relation degree(r =0.824)and optimal cluster analysis, is the best amendment for the soils contaminated by arsenic. |
