摘要: 

由於民間環保意識抬頭以及政府政策的推行,希望藉由種植紅樹林復育保護因人為開發而日漸脆弱的西部海岸。過去幾年,臺灣西部沿岸進行大規模的紅樹林栽植計劃種植以及復育紅樹林,在缺乏人為管理下使得沿岸環境受到影響。現今,紅樹林擴張造成棲地物種單一化、鳥類族群種類減少,紅樹林往河口擴張之趨勢亦影響河川排洪。
本研究以臺灣沿岸紅樹林管理為探討方向,研究對象為新竹市濱海野生動物保護區。保護區內紅樹林改變原本裸露且富含底棲生物的泥灘地並破壞臺灣招潮蟹棲地,清除紅樹林回復原先裸露泥灘地有助於提升棲地生物多樣性,從文獻整理中發現臺灣相關管理單位對於紅樹林管理政策不夠完善,紅樹林生長區域缺乏長期監測數據。研究認為制定紅樹林管理計畫能有效管理臺灣西部沿岸紅樹林分佈區域之濕地生態與環境保護。本研究研擬之紅樹林管理計畫包含5大監測項目:(1)底棲生物多樣性、(2)區域土質粒徑變化、(3)鳥類覓食區域分佈、(4)紅樹林覆蓋面積管控、(5)人為活動之影響或破壞。紅樹林管理政策之推動,除了管轄單位的長期資金投入監測及規劃,更須要區域學術單位、環保團體及民眾的配合政策推行,才能夠提升紅樹林管理成效。

外文摘要: 

The increasingly vulnerable western coast in Taiwan forced by human development has been recognized. The rising of public awareness in the environmental protection and the implementation of government policy therefore spreading the artificial mangrove planting and restoration in western coast of Taiwan, but lack of management makes the coastal environment suffering the decrease of biodiversity and obstruction of river discharge in the estuary. Nowadays, the expansion of mangrove habitat limits the habitat of other species, such birds and crabs. Species and biodiversity are singularized, it thus reducing the population of bird and other species in the estuary.
This study explores direction of the mangroves management for the western coast in Taiwan based on a case study area in Hsinchu City Costal Wildlife Refuge. The original bare mudflats have been covered by mangroves over the past decades, where the habitat becomes homogenous and landform. We suggested that appropriate replacing original bare mudflats could improve the biodiversity by clearing mangroves in the habitat. The policy of mangrove management was not integrated in Taiwan's western coastal area from the literature review. The long-term monitoring data and laws were lacked in the mangroves region. The Study suggests that the development plan of mangroves management is able to effectively monitor the growth of mangroves in the western coast of Taiwan. 5 major issues are suggested for the mangroves management: 1. Biodiversity of benthic species, 2. Variation of sediment grain size, 3. Distribution of bird’s feeding ground, 4. Surveillance of mangroves coverage, and 5. Effects of human activities. To improving the mangrove management needs not only the financial support from the government, but also the cooperation with academic institutions, environmental groups, and communities.
