| 1 | QTL mapping of the root traits and their correlation analysis with drought resis-tance using DH lines from paddy and upland rice cross显示文摘A Double Haploid (DH) population, 116 plants, derived from the cross between Japonica upland rice IRAT109 and paddy rice Yuefu, planted in PVC pipe under upland ecosystem in 2001 and 2002, was used in this study. Seven root traits, including basal root thickness (BRT), total root number (RN), maximum root length (MRL), root fresh weight (RFW), root dry weight (RDW), ratio of root fresh weight to shoot fresh weight (RFW/SFW) and ratio of root dry weight to shoot dry weight (RDW/SDW), were studied. Using index of drought resistance (IDR), the ratio of yield under upland ecosystem to yield under lowland ecosystem of DH lines, as the criteria of drought resistance, and correla-tion analysis between root traits and IDR, showed that BRT, MRL and RN were significantly correlated with IDR. High IDR lines had thicker BRT, longer MRL and less RN than low IDR lines. A molecular linkage map with 94 RFLP markers and 71 SSR markers covering 1535.1 cM was pro-duced. QTLs and G譋 interactions for BRT, RN, MRL, RFW, RDW, RFW/SFW and RDW/SDW were obtained based on the constructed molecular linkage map and soft-ware QTLmapper version 1.0. A total of 18 additive QTLs and 18 pairs of epistatic QTLs associated with root traits were detected. There were nine additive QTLs and two pairs of epistatic QTLs performed significant interactions with environment. Some QTLs with high general contribution and no G譋 interaction were obtained. Two pairs of epistatic QTLs mrl3 and mrl8, brt3 and brt11a controlling MRL and BRT had high general contributions of 21.51% and 13.03% respectively. An additive QTL and a pair of epistatic QTLs controlling RFW and RDW had high general contributions of 13.50% and 25.64% respectively. Marker assisted selec-tion (MAS) for rice drought resistance based on QTL with high general contribution, low G譋 interaction and tightly linkage with IDR were also discussed. | MUPing LIZichao LIChunping ZHANGHongliang WUChangming LIChen WANGXiangkun | 2003 | Chinese Science Bulletin2003，48，24： | 15 |

| 6 | Influence of two inlets of the Luzon overflow on the deep circulation in the northern South China Sea显示文摘An inverse reduced-gravity model is used to simulate the deep South China Sea(SCS)circulation.A set of experiments are conducted using this model to study the influence of the Luzon overflow through the two inlets on the deep circulation in the northern SCS.Model results suggest that the relative contribution of these inlets largely depends on the magnitude of the input transport of the overflow,but the northern inlet is more efficient than the southern inlet in driving the deep circulation in the northern SCS.When all of the Luzon overflow occurs through the northern inlet the deep circulation in the northern SCS is enhanced.Conversely,when all of the Luzon overflow occurs through the southern inlet the circulation in the northern SCS is weakened.A Lagrangian trajectory model is also developed and applied to these cases.The Lagrangian results indicate that the location of the Luzon overflow likely has impacts upon the sediment transport into the northern SCS. | Muping Zhou Changlin Chen Yunwei Yan Wenhu Liu | 2020 | Acta Oceanologica Sinica2020，39，11： | 1 |
| 7 | Analysis of the Comparison of Twice Regional Large Rainstorms in Northwest Yantai City显示文摘[Objective] The twice regional rainstorms in northwest Yantai in July in 2009 and July in 2010 were expounded.[Method] The twice regional rainstorm in northwest Yantai in July in 2009 and July in 2010 were selected for comparison analysis by dint of conventional and non-conventional weather data,from the aspects of circulation background,physics quantity,and radar echo,etc.[Result] The twice large rainstorm process were regional convective strong precipitation.The rainstorm fell in the northwest of Yantai and had a strong precipitation center above 200 mm.The twice large rainstorm was affected by subtropical and shear line.The rainstorm area was related to the location of 588 dagpm line,westerly trough,and shear line.It was regional rainstorm of typical subtropical edge warm and wet airstream,combination of low vortex and shear line of westerly.The precipitation occurred around the center of water vapor flux;K index had pretty good indication effects to the generation of rainstorm.Large rainstorm occurred around the place with high K index.The K index of twice large rainstorm was larger than or equal to 34 ℃,and was close to the rainstorm falling area where K index was larger than or equal to 35 ℃.The reflection factor of twice large rainstorms at 0.5° elevation,the largest echo intensity was from 55 to 60 dBz,in strip echo from south to north,through the west peninsula,forming train effect.The data report product also had important reference basis for the report of regional large rainstorm.[Conclusion] The study provided references and basis for the report of large rainstorm in the future. | LIU Xue-ping1,LUAN Dong-hong1,YU Shan-juan2 1.Yantai Meteorological Bureau in Shandong Province,Yantai 264003,China 2.Muping Meteorological Bureau in Shandong Province,Muping 264003,China | 2011 | Meteorological and Environmental Research2011，2，7： | 0 |
| 8 | Impact of Climate Change on Energy Consumption in North China显示文摘Based on the daily meteorological data with preliminary quality-control from 94 meteorological stations in North China during 1961- 2009,the impact of climate change on energy consumption in North China was analyzed by calculating heating and cooling degree-day.It's shown that the heating degree-days( HDDs) in most areas of North China reduced obviously during 1961-2009.The heating energy consumption tended to decrease with temperature rising and the reduction rate in the northern region was greater than that in the southern region.The cooling degree-days( CDDs) in most areas of North China in summer tended to increase.Besides the west of Inner Mongolia,the regions where the CDDs increased significantly in North China corresponded to the urban agglomerations of Beijing,Tianjin,Hebei and Shanxi.The rise in temperature made the cooling energy consumption increase greatly in most areas of North China in summer.The result from future climate projection reveals that the HDDs in most areas of North China will reduce persistently and the reduction rate in the northern region is also higher than that in the southern region.Simultaneously,the CDDs in most areas of North China in summer will continue to increase.The increasing rate in the southern region is higher than that in the northern region,and the most obviously increasing regions are located in the west of Inner Mongolia,Beijing,Tianjin,middle-southern region of Hebei,and south of Shanxi.This reveals that the cooling energy consumption in most areas of North China in summer will significantly increase due to climate warming. | Li Zhicai Wang Ji Shi Hongbo Guo Muping Wu Xiaozhong Liu Yueli | 2014 | Meteorological and Environmental Research2014，5，1： | 0 |
