摘要:在气候变化的背景下,人工林的碳汇能力和固碳潜力受到越来越多的关注。由于社会和经济发展的需要,橡胶林在我国的种植面积不断扩大,已然成为我国热带地区最重要的人工森林生态系统。这种土地利用方式的变化必然会影响区域水文、气侯和碳-水循环。涡度相关技术是当今世界上最先进、最广泛而精确的研究物质和能量通量的方法。然而,目前应用在橡胶林的涡度相关技术尚不多见,而这方面的数据对于应对当前全球气候变化和国际气候谈判尤为重要。作为中国通量研究网络(ChinaFLUX)的基础观测研究站点之一,自2010年建成的西双版纳橡胶林通量观测系统,如今已经累积了11年的通量和气象观测数据。本数据集整理了2010年6月到2014年12月份的西双版纳橡胶林通量和常规气象数据,包括净生态系统生产力、、生态系统呼吸、生态系统总初级生产力、潜热通量、显热通量、蒸散、空气温度、空气相对湿度、水汽压、风速、风向、大气压、太阳总辐射、净辐射、光合有效辐射、土壤温度、土壤水分、降水量等指标,分为半小时、日、月和年四种时间尺度的数据文件。本数据集可以为评价人工橡胶林生态系统生态效益和生态功能、国家制定减排相关的重大战略决策、土地利用变化管理等提供数据支撑。

Abstract: In the context of climate change, the carbon sink capacity and carbon sequestration potential of planted forests have received increasing attention in recent years. Due to the needs of social and economic development, the planting area of ​​rubber forests in China has been expanding on natural forest, and it has become the most important artificial forest ecosystem in tropical regions of China. This change in land use will inevitably cause major changes in regional hydrology, climate and carbon-water cycle. Eddy covariance technique is the most advanced, extensive and accurate method for studying matter and energy flux in the world. However, eddy covariance technique currently applied in rubber forests are still rare, and the carbon and water fluxes data in this area is particularly important for coping with current global climate change and international climate negotiations. As one of the basic observation and research sites of China Flux Research Network (ChinaFLUX), the Xishuangbanna Rubber Forest Flux Observation System was built in 2010, based on ChinaFLUX standardized data processing procedures, has now accumulated 11 years of carbon-water flux, energy Flux and meteorological observation data. This dataset compiles the rubber forest flux and routine meteorological data in Xishuangbanna from June 2010 to December 2014, including net ecosystem productivity, ecosystem respiration, gross ecosystem primary productivity, latent heat flux, sensible heat flux , evapotranspiration, air temperature, relative air humidity, water vapor pressure, wind speed, wind direction, atmospheric pressure, global solar radiation, net radiation, photosynthetically active radiation, soil temperature, soil moisture, precipitation and other indicators, forming data products of half hour, day, month, and year scales. This data set can provide data support for evaluating the ecological benefits and ecological functions of the artificial rubber forest ecosystem, making major strategic decisions related to emissions reduction, and land use change management.
