| 摘 要： | 矿山开采中产生的固体废弃物和废液会使矿区土壤中富集重金属元素,进而影响矿区内的农作物生长。选择重庆市万盛区矿区作为研究区,采集红薯和南瓜的实测高光谱数据和土壤样本的重金属含量数据。通过对土壤重金属含量和农作物的红边位置偏移进行相关分析,发现不同土壤重金属含量对研究区内主要农作物的影响是不同的。可以看出,在研究区内的两种主要农作物中,红薯对矿区土壤中的重金属Cr、Mn和Cd比较敏感,而南瓜则对以上三种土壤重金属具有一定的吸收和抵抗作用。该结果可以为万盛区矿区内农作物种植的选择提供理论依据。

| Abstract: | The solid waste and liquid generated in mining may leave heavy metal elements in soil and hence affect the growth of the crops in the mining area. By selecting Wansheng District in Chongqing as a research area, the measured hyperspectral data of sweet potato and pumpkin and the heavy metal content in the soil samples are collected. By analyzing the correlation of the heavy metal content in the soil with the red edge position of the crops, it is found that different heavy metal content in the soil has different effects on the main crops in the research area. The result shows that in the two main crops, the sweet potato is more sensitive to the heavy metal elements such as Cr, Mn and Cd while the pumpkin can absorb and counteract the above heavy metal elements in soil. This result can provide the theoretical basis for the selection of the crops to be planted in Wansheng District. |
