Supporting data for "Comprehensive Environmental Flows Assessment for Multi-guilds in the Riparian Habitats of the Yangtze River"

The files provided here are the supporting data for analyses presented in “Comprehensive Environmental Flows Assessment for Multi-guilds in the Riparian Habitats of the Yangtze River” a manuscript submitted for publication in the journal of Water Resources Research. The updated data could be divided into five categories: 1) Hydraulic model data in the excel version named “Hydraulic model data” for setup, calibration and verification for the Hydraulic model, which includes bathymetry data in the sheet named “bathymetry data” for establishment of the digital bathymetry using MIKE21 module in DHIMIKE software in the Jianli reach of Yangtze River, and the depth and velocity surveyed data on April 11 and 12, 2019 in the sheet named “depth and velocity” used to calibrate and verify the hydraulic model, and the calibrated Manning coefficient value determined from substrate information in the sheet named “Manning coefficient” for setup the hydraulic model parameters; 2) Biological samples at which the habitat conditions were simultaneously surveyed, which mainly include biomass, water depth, velocity, and substrate in sample locations for identifying the sensitive habitat factors for multi-guilds, which are in the excel named “Biological samples”; 3) Habitat hydraulic simulation results in excel named “Habitat hydraulic simulation results”, which mainly included the distribution for the depth and velocity under different discharge rates for spatial hydraulic analysis; 4) The surveyed biomass in excel named “Surveyed biomass” for target guild (e.g., larval, Juvenile, Macro-invertebrates, and Hygrophytes) to bioverify habitat simulation model; 5) Q-WUA/WUAp% and WUAp% monthly time series included Q-WUA relationship in the sheet named “Q-WUA”, Q-WUAp% relationship in the sheet named “Q-WUAp%” and WUAp% monthly time series in the sheet named “WUAp% monthly time series”, which were used for ascertaining the threshold/optimal comprehensive environmental flows and assessing the potential ecological impacts of the hydrological change caused by the Three Gorges Dam impoundment on the suitable habitat conditions of target guilds, which are in the excel named “Q-WUA/WUAp% and WUAp% monthly time series”. The results of this paper are reproducible using the openly available data provided in this resource.此处提供的文件，为投稿于《Water Resources Research》期刊的论文《长江河岸生境多功能群综合环境流量评估》（Comprehensive Environmental Flows Assessment for Multi-guilds in the Riparian Habitats of the Yangtze River）中所呈现的分析研究提供配套支撑数据。本次更新的数据可划分为五大类别： 1) 水力模型数据：以"Hydraulic model data"命名的Excel格式文件，用于水力模型的构建、率定与验证。该文件内含三个工作表：① 名为"bathymetry data"的工作表，存储了长江监利江段采用DHIMIKE软件的MIKE21模块构建数字水深地形所需的水深地形数据；② 名为"depth and velocity"的工作表，收录了2019年4月11日至12日实测的水深与流速数据，用于水力模型的率定与验证；③ 名为"Manning coefficient"的工作表，包含基于底质信息确定的率定后曼宁系数（Manning coefficient），用于设置水力模型参数。 2) 生物样本数据：以"Biological samples"命名的Excel文件，存储了同步调查生境条件时采集的样本数据，主要包括样点处的生物量、水深、流速与底质信息，用于识别多功能群的敏感生境因子。 3) 生境水力模拟结果：以"Habitat hydraulic simulation results"命名的Excel文件，主要包含不同流量下的水深与流速空间分布数据，用于开展空间水力分析。 4) 目标功能群实测生物量数据：以"Surveyed biomass"命名的Excel文件，收录了目标功能群（如幼虫、稚鱼、大型无脊椎动物与湿生植物（Hygrophytes））的实测生物量，用于生境模拟模型的生物验证。 5) Q-WUA/WUAp%与WUAp%月时间序列数据：以"Q-WUA/WUAp% and WUAp% monthly time series"命名的Excel文件，其中包含三个工作表：① 名为"Q-WUA"的工作表，收录了流量-加权可用生境面积（Weighted Usable Area，WUA）关系数据；② 名为"Q-WUAp%"的工作表，收录了流量-加权可用生境面积占比（Weighted Usable Area Percentage，WUAp%）关系数据；③ 名为"WUAp% monthly time series"的工作表，收录了加权可用生境面积占比的月时间序列数据。上述数据用于确定阈值/最优综合环境流量，并评估三峡大坝（Three Gorges Dam）蓄水引发的水文变化对目标功能群适宜生境条件的潜在生态影响。 本研究成果可通过本数据集提供的公开可用数据实现复现。
