【摘要】 土壤水热状况不仅对作物的生长、节水灌溉有着重要的作用,同时对大气环流和气候变化也影响重大,这类高质量的长期野外监测数据尤为宝贵。湖南桃源农田生态系统国家野外观测研究站地处江南丘陵复合农业生态区,该区光、热、水和生物资源丰富,气候生产潜力高,复合农业经营发达,是我国传统的粮、油、猪、棉、麻和亚热带水果生产基地。本文整理的2005–2014年土壤水热动态数据集采自桃源站气象综合观测场,样地的设置、数据的观测、采集处理方法和质量控制体系均按照中国生态系统研究网络(CERN)的统一规范进行,数据内容包括土壤体积含水量动态、土壤分层温度动态、土壤热通量数据,同时还包括气温、降雨和相对空气湿度数据。为了更好地利用这些数据,本数据集在CERN入库数据的基础上对数据进行了整理加工和再次质控。本数据集对于研究亚热带红壤区域碳循环、土壤热储量、地表能量和水分输送、以及作物生长、调整作物布局、合理安排农事生产等有重要的现实意义。更多还原

【Abstract】 Soil water and heat not only play an important role in crop growth and water-saving irrigation, but also in atmospheric circulation and climate change. High-quality long-term field monitoring data is particularly valuable. Hunan Taoyuan Aro-ecosystem National Observation and Research Station(TYA)is situated in the complex agricultural ecological area of the hills in the south of the Yangtze River, which is a traditional production base of grain, oil, pig, cotton, hemp and subtropical fruits in China. This area is rich in light, heat, water and biological resources, with high climatic potential productivity and developed complex agricultural management. This dataset was obtained at the meteorological observational site of Hunan Taoyuan Aro-ecosystem National Observation and Research Station during 2005 to 2014. The setting, observation, collection and processing methods and quality control system of the sample plots were carried out in accordance with the provisions of Chinese Ecosystem Research Network(CERN). The dataset includes soil volume water content dynamic, soil stratification temperature dynamic, soil heat flux data, as well as air temperature, rainfall and phase for air humidity data. In order to make better use of the data, this dataset is processed and re controlled based on the CERN storage data. The dataset is of great practical significance for the study of carbon cycle, soil heat storage, surface energy and water transport, crop growth, crop layout adjustment and agricultural production.更多还原
