Abstract£ºThe historical aerial photos were used to analyze and predicted the temporal and spatial variations of the vegetation changes in Tanshui River mangrove wetland in Taiwan. The results show that habitat diversity decrease due to the mangrove (Kandelia Obovata Sheue, Liu & Young) spread. The related laws and Mai Po wetland experience were examined as well to maintain the diverse habitat. Moreover, a partial-deforest experiment in southern Shir-Tzi island is underway to study the role of mangroves in estuarine environments.

Keywords£ºmangrove wetland, vegetation change, partial-deforest experiment
