摘　　要：土壤水分是土壤的重要组成部分,土壤含水量是了解和研究植物与土壤水分关系最基础的指标,对植物生长、节水灌溉等有着非常重要的作用。与短期试验相比,长期观测是对自然状况或者长期实验处理过程的多年连续观测,反映环境演变过程或人类活动的长期影响,高质量的长期野外监测数据尤为宝贵。建立于1995年的桃源站红壤坡地不同土地利用方式长期定位试验,为长期观测红壤丘陵区坡地土壤水分动态变化提供了很好的条件,本数据集来源于该试验5种坡地利用方式(农作、恢复、退化、茶园、柑橘园)不同深度(10 cm、20 cm、30 cm、40 cm、50 cm、70 cm)土壤含水量动态(中子仪法)的长期观测数据。为了更好地利用这些数据,本数据集采用中国生态系统研究网络(CERN)统一规范的数据处理方法和质量控制体系对数据进行质量控制和整理、加工,整理出5种坡地利用方式土壤水分含量的月平均数据,并提供共享下载。As an important part of soil,soil moisture is the most basic index to understand and study the relationship between plant and soil moisture.It plays a very important role in plant growth,water-saving irrigation and so on.Compared with short-term experiment,long-term observation is a multi-year continuous observation of natural conditions or long-term experimental processing process,reflecting the long-term impact of environmental evolution or human activities.High-quality long-term field monitoring data is particularly valuable.Established in 1995,the long-term positioning experiment of different utilization modes of red soil slope land in Taoyuan Agro-ecology Research Station provides a good condition for longterm observation of the dynamic changes of soil moisture on slopes in red soil hilly areas.This dataset was derived from the five management modes of slopes(farming ecosystem,restoration ecosystem,degraded ecosystem,tea garden ecosystem,citrus orchard system)in different depths(10 cm,20 cm,30 cm,40 cm,50 cm,70 cm)by neutron probe method.In order to make better use of these data,this dataset adopts CERN unified standard data processing method and quality control system,collates the monthly average data of soil moisture content of five sloping land management modes,and provides sharing service on line.
