Studies on the Tsunami damage on mangrove ecosystem and its restoration processes

调查了安达曼海海啸对红树林生态系统的长期影响，包括其大面积的格局、森林的动态和生产力、依靠渔业生产力维持当地居民生计的底栖动物以及它们多年的恢复过程。硬破坏主要出现在海岸线上。在海啸发生后的一年内，直接受到废墟袭击的林木的死亡率很高，但在林木林地的第二到第三年，只有大量的水流在泻湖红树林的深处震动。沙地复盖逐渐被潮汐冲走，但红树林栖息地几乎没有恢复，这是由于森林流失造成的根部结合丧失造成的侵蚀。沙粒淤积对底栖动物影响较大，但一些底栖动物的活动通过生物搅拌迅速恢复栖息地。

The long term impact of Tsunami occurred at Andaman ocean on the mangrove ecosystem was surveyed on its pattern in wide area, dynamics and productivity of forest, benthos fauna which sustains livelihood of local residents through fishery productivity as well as the process of their recovery over some years. Hard damage was mainly found at sea front. High mortality was found within a year following Tsunami at stands directly hit by wreckage but recorded in 2nd to 3rd year at stand only massive water flow shook at the deep interior of mangrove developed in lagoon. Sand coverage gradually was removed by tide but mangrove habitat hardly recovered due to erosion caused by the loss of binding by root caused by forest loss. Sand deposition largely affected on benthos fauna but activity of some benthos restored habitat rapidly by biotic stirring.
