Abstract
本研究以都市濕地之環境因素及生物因素發展評估都市濕地生態功能之指數，以作為管理經營都市濕地之量化參考依據。隨著人類文明之發展，人類居住愈來愈朝都市集中，因此建設都市為健康宜居城市，已成為各重要都市之主要發展目標。由於都市濕地具備生態、景觀、滯洪及休憩等功能，為健康宜居城市不可或缺之元素。因此本研究參考並修改濕地狀況指數（IWC），以水文、物理型態及水質（環境因素），以及濱水植生與水域動物（生物因素）等5個次指標，發展修正濕地狀況指數（MIWC）作為量化評估都市濕地生態功能之指數。以臺北市碧湖公園及木柵公園萃湖為案例，量化濕地生態功能，經分析2017年及2021年MIWC分數，碧湖為51分，萃湖為75分及79分，由量化之次指標，建議碧湖針對水深多樣性、棲地底床高程多樣性及物種保育部分需強化維護管理。本研究發展之MIWC，可作為都市濕地維護管理之重要評估工具。
This study introduces a Modified Index of Wetland Condition (MIWC), an innovative quantitative assessment tool developed to evaluate the ecological functions of urban wetlands. The MIWC framework, adapted from the Index of Wetland Condition (IWC), encompasses five critical sub-indices: hydrology, physical environment, water quality (environmental factors), riparian vegetation, and aquatic animals (biological factors). A comparative analysis was conducted on two urban wetlands in Taipei City-Green Lake and Tsui Lake-during 2017 and 2021. The assessment revealed that Tsui Lake demonstrated superior ecological functionality, achieving scores of 75 and 79, while Green Lake maintained a lower score of 51. Based on the sub-indices analysis, specific enhancement opportunities were identified for Green Lake, particularly in areas of water depth diversity, habitat elevation diversity, and species conservation. The study concludes by providing targeted recommendations for improving the ecological functions of both wetlands and demonstrates the MIWC's effectiveness as a practical tool for urban wetland management and conservation planning.
