On the premise of preliminary investigation in May 2017,standard plots(20 m×20 m)were set up in typical sections of small watershed to investigate the stands(Table 2).It was found that the density of 25-year artificial Robinia pseudoacacia with 750 trees·hm–2 of stand density,and the average height of trees was 14.88 m,the average DBH was 16.81 cm,and the canopy density was 0.8.Considering the influence of the cable length on the monitoring results,8 standard trees with good growth of different diameter grades,straight and complete trunk and moderate crown are selected as the sample trees in the relatively concentrated areas in the sample plots(Table 3).
