Climate change in arid areas leads to intensive drought, which causes widespread degradation in wetland ecosystems. Since wetlands play an important role in the sustainability of arid regions, climate change adaptation measures are required to conserve wetlands. However, how can we determine the regions that need increased adaptation measures? This paper aims to respond to this question and determine the regions that were highly degraded after climate change to consider them as high priority for adaptation measures. To reach this goal, degradation in the main factors that affect the functions of the Hamoun wetlands was detected in two periods, including wetland a one-year inundation period and over a 40-year period. The Hamoun wetlands are dealing with intensive drought because of the climate change that dries out these wetlands in some months and some years. Landsat images were classified using a support vector machine (SVM) in both the one-year inundation period and over 40 years to determine the regions that lost water and vegetation cover. The degradation of water bird habitat was also determined over both periods. The multicriteria evaluation (MCE) method was applied to overlay the layers and prioritize the regions for adaptation measures based on the degradation criteria. The two important contributions of this paper include introducing a functional method for the implementation of adaptation measures and running this method by the main components shared between all wetlands, which makes this method applicable in all regions.

湿地哪里需要更大的气候变化适应措施?

干旱地区的气候变化导致严重干旱,导致湿地生态系统普遍退化。由于湿地在干旱地区的可持续性中发挥着重要作用,因此需要采取气候变化适应措施来保护湿地。然而,我们如何确定需要增加适应措施的地区?本文旨在回答这个问题,并确定气候变化后高度退化的区域,将其视为适应措施的优先事项。为实现这一目标,对影响哈蒙湿地功能的主要因素进行了两个时期的退化检测,包括湿地淹没期为一年和超过 40 年。由于气候变化使这些湿地在几个月和几年内变干,Hamoun 湿地正在应对严重的干旱。Landsat 图像使用支持向量机 (SVM) 在一年淹没期和 40 年以上进行分类,以确定失去水和植被覆盖的区域。在这两个时期也确定了水鸟栖息地的退化。应用多标准评估 (MCE) 方法来覆盖层并根据退化标准确定适应措施区域的优先级。本文的两个重要贡献包括引入了一种用于实施适应措施的功能方法,并通过所有湿地之间共享的主要组件运行该方法,这使得该方法适用于所有地区。Landsat 图像使用支持向量机 (SVM) 在一年淹没期和 40 年以上进行分类,以确定失去水和植被覆盖的区域。在这两个时期也确定了水鸟栖息地的退化。应用多标准评估 (MCE) 方法来覆盖层并根据退化标准确定适应措施区域的优先级。本文的两个重要贡献包括引入了一种用于实施适应措施的功能方法,并通过所有湿地之间共享的主要组件运行该方法,这使得该方法适用于所有地区。Landsat 图像使用支持向量机 (SVM) 在一年淹没期和 40 年以上进行分类,以确定失去水和植被覆盖的区域。在这两个时期也确定了水鸟栖息地的退化。应用多标准评估 (MCE) 方法来覆盖层并根据退化标准确定适应措施区域的优先级。本文的两个重要贡献包括引入了一种用于实施适应措施的功能方法,并通过所有湿地之间共享的主要组件运行该方法,这使得该方法适用于所有地区。在这两个时期也确定了水鸟栖息地的退化。应用多标准评估 (MCE) 方法来覆盖层并根据退化标准确定适应措施区域的优先级。本文的两个重要贡献包括引入了一种用于实施适应措施的功能方法,并通过所有湿地之间共享的主要组件运行该方法,这使得该方法适用于所有地区。在这两个时期也确定了水鸟栖息地的退化。应用多标准评估 (MCE) 方法来覆盖层并根据退化标准确定适应措施区域的优先级。本文的两个重要贡献包括引入了一种用于实施适应措施的功能方法,并通过所有湿地之间共享的主要组件运行该方法,这使得该方法适用于所有地区。
