Abstract

Wetlands play an important role in cycling water resources, organic matter, water purification, and ecosystem conservation. Understanding flow regimes is essential for effective wetland management because it significantly influences wetland succession and circulation. This study aims to develop a methodology for quantifying flow regimes of the Jangdan Wetland (Imjin River) and the Binae Wetland (Namhan River). The study utilized water level duration curve (LDC) based on historical water level data from 2008 to 2023 for the Binae Wetland and from 2003 to 2023 for the Jangdan Wetland to analyze hydrological flow regimes. Flow regime diagrams describing the inundation characteristics over time, were then constructed using the LDC and the digital elevation models (DEM) of the wetlands. To understand the relationship between vegetation communities and hydrologic regime in the wetland, this study classified nine vegetation zones based on the tolerance of associated plant species to inundation (in weeks or months) reported for plant species in previous studies. The study revealed that the Jangdan Wetland were dry primarily on most days but experienced complete inundation during flooding events. In contrast, the Binae Wetlands were found to be frequently inundated, with approximately 40 % of the area experiencing regular flooding, while 20 % of the higher elevation areas were only inundated once every few years.

基于河岸湿地流态的植被带分类研究

湿地在水资源循环、有机物、水净化和生态系统保护方面发挥着重要作用。了解流态对有效管理湿地至关重要，因为流态对湿地演替和循环有着重要影响。本研究旨在开发一种量化长滩湿地（临津江）和滨内湿地（南汉江）水流状态的方法。研究利用水位持续时间曲线 (LDC) 分析水文流态，水位持续时间曲线基于 2008 年至 2023 年的滨内湿地历史水位数据和 2003 年至 2023 年的长滩湿地历史水位数据。然后，利用 LDC 和湿地的数字高程模型（DEM）构建了水流状态图，描述了不同时期的淹没特征。为了解湿地植被群落与水文流态之间的关系，本研究根据以往研究中报告的相关植物物种对淹没的耐受性（以周或月为单位）划分了九个植被区。研究显示，獐子岛湿地在大多数日子里主要处于干燥状态，但在洪水泛滥时会完全被淹没。相比之下，Binae 湿地经常被淹没，约 40% 的区域经常被淹没，而 20% 的高海拔区域每隔几年才被淹没一次。

期刊介绍： Ecological engineering has been defined as the design of ecosystems for the mutual benefit of humans and nature. The journal is meant for ecologists who, because of their research interests or occupation, are involved in designing, monitoring, or restoring ecosystems, and can serve as a bridge between ecologists and engineers. Specific topics covered in the journal include: habitat reconstruction; ecotechnology; synthetic ecology; bioengineering; restoration ecology; ecology conservation; ecosystem rehabilitation; stream and river restoration; reclamation ecology; non-renewable resource conservation. Descriptions of specific applications of ecological engineering are acceptable only when situated within context of adding novelty to current research and emphasizing ecosystem restoration. We do not accept purely descriptive reports on ecosystem structures (such as vegetation surveys), purely physical assessment of materials that can be used for ecological restoration, small-model studies carried out in the laboratory or greenhouse with artificial (waste)water or crop studies, or case studies on conventional wastewater treatment and eutrophication that do not offer an ecosystem restoration approach within the paper.
