The objectives of this study are: (1) quantifying the mangrove ecosystem services of flood prevention by calculating flood level decrease rate and erosion protection by estimating the reduction rate of drag forces, (2) identifying the habitat characteristics and related plant pathology of mangroves and establishing the GIS-based habitat suitability model of mangroves, (3) examining the mechanisms of spreading and exchanging for mangrove seeds based on hydrodynamic aspect, (4) examining the impacts and adaptation for mangrove forests under the effects of climate change, (5) examining the impacts and adaptation for mangrove forests under the effects of river and coastal engineering. The field data for validating the numerical models, TABS-2 for hydrodynamic simulation and MIKE21 for wave and near shore current simulation, will be collected. The local biotic and abiotic parameters resulted from field surveys and flume experiments will contribute into identifying the interactions and mechanisms between mangroves and environment as well. The concepts of “ecosystem functions and services” and "integrated watershed management" points of view will be taken into consideration. The optimum condition of mangrove density, coverage ratio and aspect ratio will be presented. The outcomes of this study would provide useful information to other related projects and the feedbacks will also be collaborated and incorporated. This study meets the international concern about mangrove vulnerability induced by global change and anthropogenic effects. The research results would be valuable in both academic innovation and practical application.紅樹林生態系服務侵蝕保護生育地模式氣候變遷河川海岸工程mangroveecosystem serviceserosion protectionhabitat suitability modelclimate changeriver and coastal engineering
