| 1 | Design of a new dynamical core for global atmospheric models based on some efficient numerical methods显示文摘A careful study on the integral properties of the primitive hydrostatic balance equations for baroclinic atmosphere is carried out, and a new scheme todesign the global adiabatic model of atmospheric dynamics ispresented. This scheme includes a method of weighted equal-areamesh and a fully discrete finite difference method with quadraticand linear conservations for solving the primitive equationsystem. Using this scheme, we established a new dynamical corewith adjustable high resolution acceptable to the availablecomputer capability, which can be very stable without anyfiltering and smoothing. Especially, some important integralproperties are kept unchanged, such as the anti-symmetries of thehorizontal advection operators and the vertical convectionoperator, the mass conservation, the effective energy conservationunder the standard stratification approximation, and so on. Somenumerical tests on the new dynamical core, respectively regardingits global conservations and its integrated performances inclimatic modeling, incorporated with the physical packagesfrom the Community Atmospheric Model Version 2 (CAM2) of NationalCenter for Atmospheric Research (NCAR), are included. | WANG Bin, WAN Hui, Jl Zhongzhen, ZHANG Xin, YU Rucong, YU Yongqiang & LIU HongtaoState Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics, Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029, China Department of Computational Mathematics, Academy of Mathematics and System Sciences, Peking University, Beijing 100871, China | 2004 | Science China Mathematics2004，47，z1： | 92 |
| 2 | Innovative use of controlled availability fertilizers with high performance for intensive agriculture and environmental conservation显示文摘A variety of slow release fertilizers, controlled release (availability) fertilizers (CAFs),and stability fertilizers have been developed in response to the serious drawbacks of the conventional fertilizers since the early 1960's. Of these fertilizers, CAFs which are coated with resin are consumed in the largest quantity in the world. Selecting CAFs with higher performance, the author will discuss about: 1) Innovation of agro-technologies for various field crops including new concepts of fertilizer application, 2) high yielding of field crops, 3) enhancing quality and safety of farm products, and 4) controlling the adverse effect of intensive agriculture on the environment. | Sadao SHOJI | 2005 | Science China(Life Sciences)2005，48，z2： | 14 |
| 3 | The Harmonious Dissipative Operators and the Completely Square Conservative Difference Scheme in an Explicit Way显示文摘In this paper, a new definition on harmonious dissipative operators is given and some important properties of theirs are shown. Especially, the relationship between a harmonious dissipative operator and the completely square conservative difference scheme in an explicit way is revealed. Kinds of 2-order, 3-order and 4-order harmonious dissipative operators are constructed by using the traditional Runge-Kutta method and a species of general m-order harmonious dissipative operators is established in the linear case. In addition, an efficiency parameter to appraise the time benefits of a harmonious dissipative operator is defined in this paper. It is testified in numerical tests that the harmonious dissipative operators are indeed able to improve the time-efficiency and computational effect of the completely square conservative difference scheme in an explicit way. | 王斌 季仲贞 | 1994 | Science China Chemistry1994，37，4： | 11 |
| 4 | Sequence variation and genetic diversity in the giant panda显示文摘About 336-444 bp mitochondrial D-loop region and tRNA gene were sequenced for 40 individuals of the giant panda which were collected from Mabian, Meigu, Yuexi, Baoxing, Pingwu, Qingchuan, Nanping and Baishuijiang, respectively. 9 haplotypes were found in 21 founders. The results showed that the giant panda has low genetic variations, and that there is no notable genetic isolation among geographical populations. The ancestor of the living giant panda population perhaps appeared in the late Pleistocene, and unfortunately, might have suffered bottle-neck attacks. Afterwards, its genetic diversity seemed to recover to some extent. | 张亚平 Oliver A.Ryder 范志勇 张和明 何廷美 何光昕 张安居 费立松 钟顺隆 陈红 张成林 杨明海 朱飞兵 彭真信 普天春 陈玉村 姚敏达 郭伟 | 1997 | Science China(Life Sciences)1997，40，2： | 3 |
| 5 | A study on population genetic structure of Oryza meyeriana (Zoll. et Mor. ex Steud.) Baill. from Yunnan and its in situ conservation significance显示文摘In order to determine genetic diversity of Oryza meyeriana (Zoll. et Mor. ex Steud. ) Baill., 12 enzyme systems encoded by 17 loci were electrophoretically analyzed in 164 individuals of seven populations from Simao Prefecture, Yunnan Province, China. In comparison with those seed plants with the same life history and breeding systems, as well as the other species in the genus Oryza, the species shows rather low levels of genetic diversity (A = 1.1, P = 8.0%, Ho = 0.004 and He = 0. 015) within populations and high genetic differentiation among populations. FST was up to 0. 649, suggesting that 64. 9% of total genetic variability exists among populations. Considering high genetic differentiation among populations from a limited geographic region, most of the populations of the species are worth being protected, and therefore, great natural protection regions should theoretically be established in which a great deal of populations should be involved for developing in situ conservation management. | 高立志 葛颂 洪德元 张炯伟 罗庆延 陶国达 许再富 | 1999 | Science China(Life Sciences)1999，42，1： | 3 |

| 7 | Multiple equilibria of cross-equatorial Inertial jets显示文摘Based on the developed Anderson and Moore's theory about cross-equatorial inertial jets and a nonlinear equivalence shallow water model, new universal functions are determined by the characters of the vortical large-scale air flow (atmosphere) or ocean current (ocean) related to the jet, then the potential vorticity and energy conservation equations along the streamline in the cross-equatorial in-ertial jets can be obtained. Because the governing equations are nonlinear, some limited multiple equi-libria of cross-equatorial inertial jets may exist. According to the character of large-scale air flow or ocean current outside the jets, the existent criterion for multiple eqnilibria in cross-equatorial inertial jets is discussed, and two examples for multiple equilibia of nonlinear governing equations are given. | CHAO JiPing1,2 & LIU Fei3,4 1 National Marine Environmental Forecasting Center, Beijing 100081, China 2 The First Institute of Oceanography ,SOA, Qingdao 266060, China 3 Key Laboratory Regional Climate-Environment for Temperate East Asia, Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029, China 4 Graduate University of Chinese Academy of Sciences, Beijing 100039, China | 2007 | Science China Earth Sciences2007，50，1： | 1 |
| 8 | Characteristics and conservation of biodiversity in Xinjiang显示文摘The Xinjiang Uygur Autonomous Region covers nearly 1/6 territory of China, with vari-ous landscape patterns, environmental conditions and three key regions of biodiversity of China.The ecosystem here has a relatively simple structure and fragile ecological stability. The coverageof sparse vegetation here is only 2.1% which is far lower than 14%, the average coverage all overthe country. Although the fragile and unstable ecosystems are improved partly in the past, the totalsituation in Xinjiang has worsened (such as drying up of rivers and lakes, desertification andsalinization of soil, deterioration of meadow, reduction of biodiversity, etc.). Although the speciesnumbers of Xinjiang are few, the diversity of taxa is very high. The types of plant communities areabundant, and the flora abounds in one-species genus, one-genus family and few-species genus.Also, the fauna abounds in endangered species and endemic species, of which 108 species ofvertebrates were listed as nationally protected species. In addition, there are abundantanti-adversity gene pools. The present paper puts forwards several suggestions for biodiversityconservation in Xinjiang. | 潘伯荣 张元明 | 2002 | Science China Earth Sciences2002，45，z1： | 1 |
