园林景观土壤环境重金属污染生物防治模型设计研究

Design of Biological Control Model for Heavy Metal Pollution in Landscape Soil Environment

由于目前采用的常规生物防治方法缺乏针对性,导致园林景观土壤环境重金属污染恢复效果无法达到预期目标。为此针对常规生物防治方法存在的问题,设计一种园林景观土壤环境重金属污染生物防治模型。该模型分为三部分第一部分利用LIBS技术检测园林景观土壤环境重金属成分和含量;第二部分利用构建的土壤重金属污染综合评价模型判断土壤重金属污染程度;第三部分在上述两部分的基础上针对性的选择合适的生物防治措施,实现污染土壤恢复。

Due to the lack of pertinence of the conventional biological control methods currently used,the restoration effect of heavy metal pollution in landscape soil environment is far from the expected goal.In view of the problems of conventional biological control methods,a biological control model of heavy metal pollution in landscape soil environment was designed.The model is divided into three parts:the first part uses LIBS technology to detect the composition and content of heavy metals in the soil environment of landscape architecture;the second part uses the comprehensive evaluation model of soil heavy metal pollution to judge the degree of soil heavy metal pollution;the third part chooses appropriate biological control measures on the basis of the above two parts.To restore polluted soil.
