Abstract

This study aims to examine the degradation process of urban stream landscapes in Tekirdağ by utilizing a newly developed degradation index (DI) that effectively defines degradation. The DI considers the vital factors that affect urban stream landscapes, making it possible to determine the level of degradation and resulting environmental quality. This index aims to provide valuable insight into the degradation of urban stream landscapes with a minimal amount of independent variables and training samples. The key enhancements of the DI include its clear computation of degradation value, ease of replication, and overall objectivity. The results indicate that the most substantial change has been observed on impermeable surfaces between 2000 and 2020, resulting in a 5.18% increase in impervious surfaces. Furthermore, there has been a decrease by 4.67% in agricultural lands, highlighting a pronounced shift towards impervious surfaces. The total percentage of areas categorized as high and very high degradation categories increased by 1.54% over the study period. Additionally, the area classified as high degradation expanded from 135.91 to 375.42 hectares between 2000 and 2020. Notably, there was no land classified as very high degradation in 2000, whereas in 2020, it reached 38.15 hectares. The DI has been proven to provide better representational information on how human activity affects ecosystems compared to both the Human Influence Index and the Human Footprint Index which has been used for this purpose. As a valuable tool for urban planning strategies, the DI can provide decision-makers with a more precise depiction of degradation, aiding in the preservation of sustainable urban stream landscapes, particularly in rapidly urbanizing areas.

简化复杂性:新的城市水系景观退化指数——以Tekirdag为例
本研究旨在利用新开发的退化指数(DI)来有效定义退化,从而研究 Tekirdağ 城市溪流景观的退化过程。退化指数考虑了影响城市溪流景观的重要因素,从而可以确定退化程度和由此导致的环境质量。该指数旨在通过最少的自变量和训练样本,为城市溪流景观的退化提供有价值的见解。退化指数的主要优点包括退化值计算清晰、易于复制以及整体客观性。结果表明,2000 年至 2020 年间,不透水表面的变化最大,不透水表面增加了 5.18%。此外,农业用地减少了 4.67%,突显了向不透水地面的明显转变。在研究期间,被归类为高度和极度退化类别的地区总比例增加了 1.54%。此外,从 2000 年到 2020 年,被归类为高度退化的面积从 135.91 公顷扩大到 375.42 公顷。值得注意的是,2000 年没有土地被归类为极度退化,而到 2020 年则达到了 38.15 公顷。事实证明,与人类影响指数和人类足迹指数相比,《退化程度指数》能更好地反映人类活动对生态系统的影响。作为城市规划战略的重要工具,《退化指数》可以为决策者提供更精确的退化描述,有助于保护可持续的城市河流景观,尤其是在快速城市化的地区。

期刊介绍: Environmental Monitoring and Assessment emphasizes technical developments and data arising from environmental monitoring and assessment, the use of scientific principles in the design of monitoring systems at the local, regional and global scales, and the use of monitoring data in assessing the consequences of natural resource management actions and pollution risks to man and the environment.
