北京市农林科学院20年来获得国家自然科学基金面上项目资助情况回顾与分析

北京市农林科学院是北京市农业科学技术综合性研究机构,成立于1958年,主要承担国家及北京市农业应用基础及应用研究、高新技术研究与创新、农业科技成果的推广、产业化服务等任务。回顾20年来我院获得国家自然科学基金面上项目资助的情况,分析学科发展,总结经验与不足,对促进我院基础研究发展具有十分重要的意义。     

创新是发展的根本动力

创新是一个复杂的价值创造过程,是经济发展的决定性力量。创新驱动发展涉及现代化建设的方方面面,包括科学技术创新、商业模式创新、制度创新、管理创新和社会创新以及人才培养机制创新。为实现创新驱动发展,需要完善国家创新生态系统,加速政府职能转变,着力营造良好的创新制度文化环境,激发创新主体的创新活力,强化创新基础条件平台建设,弘扬中华民族的创新文化和创新精神,形成全社会关心创新、参与创新的良好发展局面,加快建设创新型国家和全面建成小康社会。     

论中国都市农业的发展-以北京市为例

传统农业的观念,总是把城市与乡村、工业与农业对立起来,误认为城市的发展必然以牺牲农业为代价。因而,在实现工业化的过程中,把城市外围近郊的大量农田变成非农用地,使城市变成了“水泥丛林、柏油沙漠”的景象,于是农业在大城市中被轻视、被压缩、被吞没、被废弃。发展都市农业是工业化国家经济发展的必然趋势。在我国是一种新形态,对建设具有中国特色的农业具有重要战略地位。北京是我国的首都并是特大的都市,以其为例在全国乃至世界具有典型意义。     

Benefits evaluation of water resources used for ecosystem in Shiyang River basin of Gansu province

Among the numerous inland river basins in the arid northwest China, Shiyang River basin is known for its most serious water shortage that constrains its social and economic developments and for some of the worst eco-logical and environmental deterioration in China. The research on the value of water resources used for ecosystem is the basis for reasonable allocation of water resources between users of ecosystem and economic system. In this paper the concept of dynamic value for the ecosystem services is proposed. A modified coefficient for the ecosys-tem service value per unit area is proposed according to the cover degrees of biomes combined with expert consul-tation. Based on the developmental stage coefficient and scarcity of ecological resources, a dynamic evaluation method is proposed. The theoretical formula and simple calculation formula of the sharing benefits coefficient and benefits per unit ecological water utilization are proposed. The result shows that the benefit of unit ecological water utilization in the lower reach was greater than that in the upper reach in the Shiyang River basin.     

三维重建法测量中国北方成人股骨膝外翻角(英文)

研究目的:利用三维重建影像模型获取膝外翻角,并通过使用这种方法来测量中国北方成人膝外翻角的平均估计值。创新要点:本研究所获取的膝外翻角平均值对于在中国北方人群进行膝关节置换术时有着重要的参考意义,新的三维重建测量法使得膝外翻角的术前个体化测量更加精确。研究方法:利用64名患者的CT血管造影(CTA)的DICOM数据获取共128件股骨三维重建模型。在重建的股骨模型上分别定位髁间凹最高点(点A)、膝关节线上20 cm截面的髓腔中点(点B)和股骨头旋转中心(点C)。之后膝关节外翻角即由股骨远端解剖轴(线AB)与股骨机械轴(线AC)所围成(上述定位过程详见图5)。经统计分析后,128件股骨的平均外翻角值为6.20°±1.20°。统计分析还发现,膝外翻角与个体年龄呈显著性正相关,同一个体的左右侧外翻角呈显著性正相关。重要结论:在对北方成年人群进行膝关节置换术时,选取外翻角为6°可会在重建人体下肢力线上获得更好的术后效果。在对年长患者进行手术时应选用更大的外翻角。     

传媒在两岸政党沟通中的角色审视

传媒是承载政治、经济、文化与社会信息的基本载体,也是两岸政党沟通的重要途径。本文简要回顾两岸政党沟通的基本历程,认为传媒在促进两岸政党交流与沟通中,发挥着促进相互认知、培育情感认同、弥合政治分歧以及提供舆论支持的作用,并经历了传递政策、传递事实和传递影响力的角色变迁。在此基础上,本文还探讨了传媒在促进两岸政党沟通中存在的问题和相应的对策。
