Influence of the gregarious flowering and death of bamboo to ecosystem and shifting cultivation agriculture in Mizoram, India

在印度米佐拉姆邦的竹（Melocanna baccifera）群居开花和死亡地区，通过植被调查和DNA分析研究监测了恢复过程。此外，还进行了大范围的开花期提取试验，探讨了轮作农业生产力与开花期的关系以及鼠类种群的变化。利用卫星影像进行大面积研究，发现该树种在其分布区域连续数年呈波浪开花。在许多情况下，轮作农业的做法对该物种的恢复产生了良好的影响。鼠类种群的变化在开花后的几年内趋于收敛。

In the area the bamboo(Melocanna baccifera) flowered gregariously and died in Mizoram, India, recovery process was monitored by the research of vegetation surveys and the DNA analysis. In addition, trials of extraction of the flowering area in a broad scale, a discussion of the relationship between productivity of shifting cultivation agriculture and flowering timing, the change of rodent population, were done. Through the broad area research using satellite images the flowering of this species occurred in waves for several years in its distributing area. The practice of shifting cultivation agriculture influences good results for the recovery of this species in many cases. The change of rodent population converged in a few years after flowering.
