| 摘 要： | 2013年夏季,我国东南部地区发生了严重的高温干旱天气,毛竹林受灾严重。通过设置固定样地研究了高温干旱后毛竹林的受灾状况以及灾后竹林的自恢复能力。结果表明:在高温灾害发生以后,胸径较大的毛竹抵御灾害的能力高于胸径较小的毛竹;受灾毛竹地上部分生物量80%以上分布在竹秆中,因此竹枝和竹叶受损对毛竹地上生物量的影响不大;毛竹林受灾后的恢复能力在很大程度上取决于受灾当年新生竹的株数。因此,在毛竹林经营中应加强林地的水肥管理,培育大径竹材,同时应保持较高的立竹密度和较多的新生竹数量,以抵御旱灾并加快林分的灾后恢复。

| Abstract: | In the summer of the year 2013, the southeast part of China was hit by severe drought where the moso forest suffered from a harsh hazard. The paper studied the moso bamboo's suffer from drought disaster and their self-recovery capacity from the suffer using fixed sample and tracking survey. The results showed that after hit by high temperature disaster, the moso with large DBH showed better capacity against the disaster than the ones with smaller DBH; more than 80% of affected aboveground biomass was concentrated in culms while the affected bamboo branches and leaves had the least impact on the aboveground biomass; the self-recovery capacity of moso bamboo after the disaster depends to a large extent on the plants of new bamboo of the same year. Therefore, in the moso bamboo forest management, more efforts should be put to the water and fertilizer management and large diameter bamboo timber cultivation, and also, more attention should be placed on the higher stand density and more new bamboo growth so as to stand against the drought and increase the recovery of bamboo stand after the disaster. |
