通过对受雨雪冰冻危害的毛竹林受损数量和经一个春笋大年的新竹留养数量,分析了受害后毛竹的繁衍恢复特点。结果显示:与灾前相比,毛竹平均株数增加29.8%,春笋产量减少21.7%;新竹平均株数t值=4.22>t(14)0.01(2.977),增加14.2株;毛竹受损率与留养新竹之间,其相关方程为y=0.414 1x+21.978,R2=0.300 9,没有紧密的相关性;新竹大径材减少4.4%~12.1%,没有达到灾前比例。
By analyzing the damaged quantity of Moso bamboo forest endangered by rain, snow and ice and the number of bamboo kept in Hsinchu during a spring bamboo shoot, the characteristics of reproductive recovery of Moso bamboo were analyzed. The results showed that the average bamboo number increased by 29.8% and that of bamboo shoots decreased by 21.7% compared with that before the disaster. The average value of t of Hsinchu was 4.22 t (14) 0.01 (2.977), an increase of 14.2 strains. Hsinchu, the correlation equation is y = 0.414 1x + 21.978, R2 = 0.300 9, there is no close correlation; Hsinchu large diameter timber decreased by 4.4% to 12.1%, did not reach the pre-disaster ratio.
