摘　　要：基于中国科学院盐亭紫色土农业生态试验站(简称盐亭站)对川中丘陵区典型小流域地表水环境状况的长期常规监测,集成2005–2019年川中丘陵区典型小流域地表水环境特征数据集。本数据集涉及典型小流域内布设的4个监测点,分别位于小流域的沟头池塘、中游汇水沟渠、集水区出口处的田面和堰口;2005–2006年,每3个月采集1次水样,2007–2009年,加采8月和9月的水样,2010–2019年则每月采集1次,采集样品时间均为每月20日,数据包含反映地表水环境的酸碱度、总氮、总磷、矿化度、电导率、化学需氧量、钙离子、镁离子、钾离子、钠离子、碳酸根离子、重碳酸根离子、氯化物、硫酸根离子、磷酸根离子和硝酸根离子等16个理化指标。监测样点布设、采集水样过程、实验室分析和数据分析均遵照中国生态系统研究网络(CERN)和国家科技基础平台要求的规范和标准进行,数据质量可靠,并与网络其他野外台站同类数据具有可比性。可为环境科学研究、生态清洁小流域以及水环境综合评价、管理和规划提供重要数据支持。Based on the long-term routine monitoring of surface water environmental status of typical small watershed in the central hilly region of Sichuan Province by Yanting Station,we compiled a the dataset of surface water environmental characteristics of typical small watersheds in central Sichuan Hilly Region from 2005 to 2019,involving four monitoring sites in typical small catchments located in the upper of small catchment pond,the midstream ditch,field surface and the weir at the outlet of the catchment.From 2005 to 2006,water samples were collected at regular intervals of once every three months;starting from 2007 to 2009,water samples from August and September were specifically added;from 2010 to 2019,the sampling frequency increased to once a month,with water samples collected specifically on the 20th day of each month.The data include 16 physical and chemical indicators reflecting the surface water environment,namely pH,TN,TP,TDS,EC,CODcr,Ca^(2^(+)),Mg^(2^(+)),K^(+),Na^(+),CO_(3)^(2-),HCO_(3)^(-),Cl-,SO_(4)^(2-),PO_(4)^(3-)and NO_(3)^(-).The monitoring sample layout,water sample collection process,laboratory analysis and data analysis were carried out in accordance with the specifications and standards required by the China Ecosystem Research Network(CERN)and the National Science and Technology Basic Platform.The data are of reliable quality and comparable with similar data collected from other field stations on the network.The dataset can provide important data support for environmental science research,ecologically clean small watersheds and comprehensive water environment evaluation,management and planning.
