Effects of tending measures on the glaze-harmed stand and understory shrub growth
In order to explore the effect of glaze harm on the stand forest and understory shrub growth,a sample-plot survey was conducted.The results showed that the resistance of different tree species to glaze disaster is different in a sequence of Quercus mongolica,Tilia spp.,Larix principis-rupprechtii,Betula platyphylla and Pinus tabulaeformis from light to heavy.Through tending the stand forest of oak,tilia,larch,and birch harmed by glaze,there was a significant increase in average DBH (108％,117％,111％,113％) and tree volume (111 ％,146 ％,104 ％,121％),respectively except for the pine stand which was the most heavely affected by glaze,resulting in a decrease of its average DBH and tree volume.It is concluded that tending against glaze harm to stand is supposed to promote the growth of the seedlings and understory shrub.
