树木根系高密度电阻率法探查试验研究

Detection of Tree Root Distribution Characteristics by High-density Resistivity Method

为了验证高密度电阻率法探测树木根系发育情况的可行性,本文通过在法国梧桐(Platanus orientalis Linn.)和重阳木Bischofia polycarpa(Levl.)Airy Shaw根系周围布置不同的高密度电阻率法采集方式,分别得到其根系周围的视电阻率剖面图和不同深度的电阻率反演平面图,从而推测其根系分布情况。结果表明,法国梧桐和重阳木具有不同的根系分布特征,探测所得到的根系分布情况与实际根系分布情况一致。

In order to verify the feasibility of high density electrical method to detect the root development of trees,by arranging the different method around the root of the French plane(Platanus orientalis Linn.)and the bischofia polycarpaBischofia polycarpa(Levl.)Airy Shaw,we got the apparent resistivity profile about the root distribution and the inversion of resistivity at different depths.Results showed that the French plane had a different root distribution characteristics from bischofia polycarpa,and the root distribution was consistent with the actual root distribution.
