稻油轮作稻田甲烷排放及其总量测定填充柱
稻油轮作稻田甲烷排放及其总量测定填充柱 详细信息：

名称：填充柱
规格：2m*3mm
型号：TDX-01

1995～ 1997年 3年的实验研究中 ,浩瀚色谱（山东）应用技术开发有限公司用静态箱法和气相色谱仪对**地区不同水管理方式稻田的甲烷排放进行了采样和测量工作 ,1996年和 1997年逢晴天还同步进行了地面实验基地的卫星遥感数据 (TM和NOAA—AVHRR数据 )的接收工作.根据测算的稻田甲烷排放通量和用遥感数据提取的水稻种植面积 ,估算出区域尺度的稻田甲烷排放总量. 3年来的研究结果显示 ,**地区水稻种植面积为 17.72 12× 10 4 hm2 ,稻田甲烷平均排放通量为 2 .984mg/(m2 ·h) ,长春地区稻田甲烷总排放量为 0 .0 2 0 3Tg/a.用灰关联方法分析了稻田甲烷排放的影响因子 ,建立了以水稻植被指数为参数的淹灌稻田的甲烷排放通量估算模型.

Methane emissions from rice-oil cropping paddy fields and its total measurement packed column
Methane emissions from paddy fields in rice oil rotation and its total measurement packed column Details:

Name: Packed column
Specification: 2m*3mm
Model: TDX-01

In the three years of experimental research from 1995 to 1997, Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used static box method and gas chromatograph to sample and measure methane emissions from rice fields with different water management methods in the ** area, 1996 It also carried out the reception of satellite remote sensing data (TM and NOAA-AVHRR data) from the ground experimental base at the same time as in 1997 on a sunny day. based on the measured methane emission flux from the rice field and the rice planting area extracted with remote sensing data, the regional scale was estimated The total amount of methane emissions from rice fields in the past three years shows that the rice planting area in the ** area is 17.72 12 × 10 4 hm2, and the average methane emission flux from the rice fields is 2.984 mg/(m2 · h). The emission amount is 0.02 0 3Tg/a. The influencing factors of methane emission from rice fields are analyzed by gray correlation method, and a model for estimating methane emission flux from submerged rice fields with rice vegetation index as a parameter is established.
