摘要:

在黄土高原半干旱雨养农业区薯麦轮作田地建立气象部门首家FACE系统(Free Air CO2En-richment),即CO2浓度的控制和监测系统平台,由中国气象局兰州干旱气象研究所建在定西半干旱生态环境与试验基地。该平台由CO2气体供应装置、控制系统、释放系统3大部分组成,它是利用计算机网络系统对平台的CO2浓度进行监测控制,根据作物冠层高度的CO2浓度、风向、风速、昼夜的变化调节CO2气体的释放速度及方向,实现FACE圈的CO2浓度高于周围大气CO2浓度某一数值。该平台旨在研究雨养农业区CO2浓度升高及其与温度、水分、养分等偶合对农作物生长过程、生理生态特征、生物量、产量等的影响,为该地区适应未来不同气候变化情景提供科学依据。

关键词: FACE(自由大气中CO2浓度富集)平台, 结构, 控制, 半干旱雨养农业区

Abstract:

A Free Air CO2Enrichment(FACE)System for potato and spring wheat rotation was established in the semi-arid rainfed area of Loess Plateau in northwest China.It is composed by CO2 gas supply device,control equipment and gas release equipment.Elevated CO2 concentration was controlled above ambient by computer system platform according to ambient CO2 concentration variation,wind direction,wind speed,canopy height and daylight changing etc.The platform aimed at the studies such as the impact of elevated CO2 concentration or coincidence with temperature,water and nutrition,etc.on growth,ecophysiological characteristics,biomass and yield of crops,which can provide some science basis for adaptation the different climate change scene in local area.

Key words: free air CO2enrichment(FACE), potato and wheat rotation, platform structure, control, semi-arid rainfed area
