Yangtze River basin ecological and hydrogeomorphic data relevant to regional hydrologic classification for sustainable dam operation

While some rivers have been modified and regulated for centuries requiring recovery efforts and restoration, other rivers are currently under development and facing the challenges of environmental degradation and loss of ecological functionality. As countries, such as China, expand current infrastructure to develop and construct flood reduction, hydropower, and water storage facilities along their rivers, the threat of detrimental ecological impacts expands too. To address these pressing challenges, this data set was used in the referenced article's analysis. Climatic, hydrogeomorphic, ecological, and anthropogenic characteristics summarized in this dataset were analyzed to determine the key principal components relevant to decision-making for environmental flows in the river basin. This resulting dataset includes a summary of the applied variables by subbasin cluster as discussed in detail in the article.

数个世纪以来，部分河流已被改造并实施管控，亟需开展修复与恢复工作；另有部分河流正处于开发阶段，面临环境退化与生态功能丧失的严峻挑战。诸如中国在内的诸多国家，正依托现有基础设施建设，沿河流开发修建防洪、水电及蓄水设施，由此带来的生态负面影响威胁亦随之加剧。为应对这些紧迫挑战，本数据集被应用于所引论文的分析研究中。本数据集汇总了气候、水文地貌、生态及人为活动特征，通过分析此类特征以确定与流域环境流量(Environmental Flows)决策相关的关键主成分。本最终数据集按子流域集群汇总了研究所用的变量，具体细节已在论文中详细阐释。
