共建和谐新农村——鄢陵局开展驻村帮扶工作侧记

正夏日的傍晚,在鄢陵县南坞乡秦岗村的文化广场上,村秧歌队的队员们正在排练节目;健身广场上,几位老人正悠闲地锻炼身体……说起村里的变化,老党员陈老汉感慨地说:"咱村今年变化就是大,广场有了,道路硬化了,文化大院也建起来了,这都多亏了国土局。没有他们的帮扶,我们村哪有这么大的变化?咱全村人都应该好好感谢国土局,感谢党和国家的好政策。"自今年初鄢陵县国土资源局与南坞乡秦岗村结对共建后,该局把驻村帮扶工作同党的群众路线教育实践活动结合起来,始终坚持真心帮扶、项     

Variability of Atlantic Meridional Overturning Circulation in FGOALS-g2简

The variability of Atlantic Meridional Overturning Circulation （AMOC） in the pre-industrial control experiment of the Flexible Global Ocean-Atmosphere-Land System model, Grid-point Version 2 （FGOALS-g2） was investigated using the model outputs with the most stable state in a 512-yr time window from the total 1500-yr period of the experiment. The period of AMOC in FGOALS-g2 is double peaked at 20 and 32 years according to the power spectrum, and 22 years according to an auto-correlation analysis, which shows very obvious decadal variability. Like many other coupled climate models, the decadal variability of AMOC in FGOALS-g2 is closely related to the convection that occurs in the Labrador Sea region. Deep convection in the Labrador Sea in FGOALS-g2 leads the AMOC maximum by 3-4 years. The contributions of thermal and haline effects to the variability of the convection in three different regions [the Labrador, Irminger and Greenland-Iceland- Norwegian （GIN） Seas] were analyzed for FGOALS-g2. The variability of convection in the Labrador and Irminger Seas is thermally dominant, while that in the colder GIN Seas can be mainly attributed to salinity changes due to the lower thermal expansion. By comparing the simulation results from FGOALS-g2 and 11 other models, it was found that AMOC variability can be attributed to salinity changes for longer periods （longer than 35 years） and to temperature changes for shorter periods.     

An Overview of BCC Climate System Model Development and Application for Climate Change Studies

This paper reviews recent progress in the development of the Beijing Climate Center Climate System Model(BCC-CSM) and its four component models(atmosphere,land surface,ocean,and sea ice).Two recent versions are described:BCC-CSM1.1 with coarse resolution(approximately 2.8125°×2.8125°) and BCC-CSM1.1(m) with moderate resolution(approximately 1.125°×1.125°).Both versions are fully coupled climate-carbon cycle models that simulate the global terrestrial and oceanic carbon cycles and include dynamic vegetation.Both models well simulate the concentration and temporal evolution of atmospheric CO_2 during the 20th century with anthropogenic CO2 emissions prescribed.Simulations using these two versions of the BCC-CSM model have been contributed to the Coupled Model Intercomparison Project phase five(CMIP5) in support of the Intergovernmental Panel on Climate Change(IPCC) Fifth Assessment Report(AR5).These simulations are available for use by both national and international communities for investigating global climate change and for future climate projections.Simulations of the 20th century climate using BCC-CSMl.l and BCC-CSMl.l(m) are presented and validated,with particular focus on the spatial pattern and seasonal evolution of precipitation and surface air temperature on global and continental scales.Simulations of climate during the last millennium and projections of climate change during the next century are also presented and discussed.Both BCC-CSMl.l and BCC-CSMl.l(m) perform well when compared with other CMIP5 models.Preliminary analyses indicate that the higher resolution in BCC-CSM1.1(m) improves the simulation of mean climate relative to BCC-CSMl.l,particularly on regional scales.

河西绿洲农田土壤呼吸特征及其对长期施肥的响应

以河西走廊典型的荒漠绿洲新垦农田为研究对象,设置9个施肥处理（高量有机肥,M3;高量氮磷肥,NP3;低量氮磷肥+高量有机肥,NP1M3;低量氮磷钾肥,NPK1;中量氮磷钾肥,NPK2;高量氮磷钾肥,NPK3;低量氮磷钾肥+高量有机肥,NPK1M3;中量氮磷钾肥+中量有机肥,NPK2M2;高量氮磷钾肥+低量有机肥,NPK3M1）,于2019—2020年7—8月采用LI-COR 8100对玉米农田土壤呼吸进行观测,分析土壤呼吸的变化、日动态及其主要影响因素。结果表明：（1）不同施肥处理,土壤呼吸速率M3>NP3>NPK1M3>NPK3M1>NPK2M2>NP1M3>NPK2>NPK3>NPK1,单施有机肥能显著提高土壤呼吸速率,较其他处理增长22.1%—41.4%。（2）不同施肥措施土壤呼吸日变化呈单峰曲线,峰值出现在13：00—16：00,土壤呼吸日变化主要受土壤温度变化的影响。（3）土壤温度和土壤湿度分别解释了土壤呼吸变化的24.2%—44.8%和7.7%—36.4%,土壤呼吸与土壤温度显著正相关,而与土壤湿度无显著相关性,不同施肥处理土壤呼吸温度敏感性系数Q₁₀值1.419—1.600。（4）土壤呼吸与有机质、总氮、总碳、碱解氮存在显著正相关关系,施用有机肥使土壤有机质、总氮、总碳、碱解氮分别提升188.9%、80.5%、79.3%、147.0%,进而促进土壤呼吸,土壤呼吸与玉米产量无显著关系。不同的施肥措施会对土壤质量和土壤呼吸产生不同影响,有机肥和氮磷钾化肥的平衡施用,能够在提升土壤质量的同时减少碳排放,可在生产实践中采用。
