Research on Root Distribution and Safety Risk of Ficus virens in Three Main Roads of Chongqing
In order to understand the root distribution and safety risk of Ficus virens in Chongqing,this study uses the TRU tree radar detection system to conduct non-destructive detection root system of the Ficus virens as a side-walk tree.Through its root distribution,combined with the establishment of the ground environment to judge the safety risks of its existence,it aims to guide the later period risk prevention and management.The results show that Ficus virens ≥3cm root on the vertical distribution of the root system is gradually increasing with increase of the soil depth;In the horizontal distribution,the Ficus virens≥3cm root in the X1 and X2-like segments is gradu-ally increasing with the increase of the distance from the tree.However,X3 sample segment showed a trend of first increasing and then decreasing.At the same time,the root distribution is the main factor that affects the safety of the trees.
