中文摘要:基于涡度相关技术,对新疆典型绿洲棉田进行了连续4年的碳通量观测,并探讨覆膜滴灌棉田生育期内碳通量的构成和特征。结果表明:生长盛期(6—9月),棉田的总初级生产力(GPP)和净生态系统碳交换(NEE)日变化明显,峰值约出现在14:00。生态系统呼吸(Res)日变化稳定,与膜下土壤温度日变化稳定有关。日间GPP随太阳净辐射(Rnet)增加而增大,可用直角双曲线方程描述;且最大光合速率的峰值出现在7月。各碳通量的季节变化不同:GPP和NEE与LAI的季节变化一致,峰值出现在7月;而Res的峰值出现在6月。月累积GPP在6—9月间主要分配给NEE;而其余月份则分配给Res。整个生育期内(5—10月),总GPP平均为816.2gC/m2,其中NEE占58.6%,这表明生育期内覆膜滴灌棉田表现为碳汇。

Abstract:Carbon and water fluxes of cotton field with plastic mulched drip irrigation were measured using an eddy covariance (EC) technique in 2009, 2010, 2012 and 2013 at Wulanwusu experimental station, which was a representatively agricultural oasis in northern Xinjiang. The diurnal pattern of mean monthly gross primary production (GPP) and net ecosystem exchange (NEE) showed an obviously sinusoidal dynamic from June to September, whilst that of ecosystem respiration (Res) stayed low and stable between daytime and nighttime. The response of daytime hourly GPP to net solar radiation (Rnet) could be expressed by a rectangular hyperbolic function. The variations of maximal assimilation rate (A) were followed changes in LAI, and the peak value occurred in July. The seasonal variations of GPP and NEE were close to the cotton phenology, and they almost reached the peak value in July. However, seasonal variations of Res didn’t follow that of LAI, and the maximum value occurred nearly one month earlier than that of LAI. Seasonal NEE showed a carbon sink from squaring to harvest period, whilst it indicated a carbon source before the squaring time as well as after the harvest time. The cumulative GPP averaged 816.2gC/m2 during the growing season (from April to October), and more than half of GPP was partitioned into NEE (meanly -478.6gC/m2).

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
