对新疆畜禽规模化养殖发展情况的调查分析

近几年来,新疆牛羊肉消费激增,价格大幅上涨,已影响到居民的正常生活,并引起了社会各方的高度关注。而走畜禽规模化养殖发展之路可以提高畜产品的供给能力,因此,本文通过实地调查资料,分析了当前新疆畜禽规模化养殖的特点及存在的问题,希望能通过加大政策扶持力度等措施来提高新疆畜禽规模化养殖发展水平。     

Economic Analysis of Animal Genetic Resources and the Use of Rural Appraisal Methods: Lessons from Southeast Mexico

Livestock diversity provides genetic alternatives that facilitate sustainable agricultural development. Despite this, animal genetic resources (AnGR) are being depleted at alarming rates. Subsidises available to production systems based on imported breeds are of several orders of magnitude greater than the costs of local breed conservation. Economic arguments for the conservation and sustainable use of threatened AnGR can be an effective means of establishing support for the development of appropriate enabling environments. Despite the importance of the economics of AnGR conservation, the subject has received limited attention. Reasons include: methodological difficulties inherent in valuing genetic resources; limited knowledge about appropriate analytical techniques; and lack of data regarding local breeds. As recent advances in economic valuation have eased methodological/analytical constraints, the issue of data availability has become critical. Data related to livestock keepers' preferences for different genetic resource attributes and the value placed on these across species, breeds and production systems are needed. Based on a study of a local pig breed in Mexico, this paper shows how the use of rural appraisal methods, in conjunction with recently developed analytical techniques, are capable of providing the data required for understanding the type and costs of interventions necessary to promote the conservation and sustainable use of AnGR.

Animalizing India: emerging signs of an unruly market

Focusing on recent artistic and photojournalistic portraits of India as an animal – an elephant or tiger – that wanders alone or sometimes with another animal companion – dragon or panda bear – called China, this article analyzes the ways in which India's potential as an emerging market and a rising power is being conjured in the popular aesthetics of magazine and nonfiction book covers. Even as an outpouring of verbal discourse from business and policy experts has hailed an India that is transitioning from a peripheral Third-World nation to a rising power, a steady stream of visual illustrations, including, those that deploy animal avatars, has sought to illuminate the vicissitudes of India's newfound economic recognition. Ultimately, my article's tracking of the visual semiotics of India's animal imprints seeks to get inside an economy of appearances in which zoological embodiments arbitrate this non-Western nation's prospects for entering economic globalization's newly minted scale of “emerging market.”     

京津冀畜牧业碳排放效率时空演变特征及影响因素分析

目的 研究京津冀畜牧业碳排放效率的时空演变特征，明晰畜牧业碳排放效率影响因素，促进畜牧业低碳可持续发展。方法 文章基于2000—2020年京津冀13市的面板数据，运用超效率EBM模型、空间自相关分析、空间计量模型等方法，对畜牧业碳排放效率的时空演变规律和影响因素进行探讨。结果 （1）2000—2020年京津冀畜牧业碳排放效率均值由0.45增长至0.88，整体水平不断提升，地区之间的碳排放效率差异呈现缩小趋势。（2）2000—2020年京津冀畜牧业碳排放效率呈现由“低值区集中连片，高值区分散”的格局向“高值区集中连片”的布局过渡的趋势，且相异空间集聚程度逐渐减弱。（3）乡村从业人员文化程度、畜牧业碳排放强度分别为当地碳排放效率的主要驱动与抑制因素，城镇化水平和乡村从业人员文化程度能改善邻近区域碳排放效率值。饲料用量、畜牧业技术进步、畜牧业产业结构、城镇化水平对碳排放效率的阻碍作用逐步显著加强；畜牧业经济发展水平和科技政策对其的驱动作用逐步显著加强。畜牧业经济发展水平和畜牧业产业结构对邻近区域碳排放效率的负向影响逐步显著加强。结论 京津冀畜牧业碳排放效率有一定的提升空间，各地区要因地制宜并加强区域合作，推动畜牧业低碳高效发展。     

生态视角下的内蒙古绒山羊生产规模分析

羊绒业是内蒙古的一大特色产业，同时也是内蒙古少数在国际市场上拥有较大影响力的产业之一。但随着内蒙古羊绒业总产值的增加，厂商数目不断增加，规模不断扩张的同时，其原料——山羊绒的供给问题越来越凸显出来。一方面是对羊绒原料需求的增加派生出山羊养殖的增加，但另一方面却是山羊养殖的增加对生态环境带来严重影响。文章从内蒙古绒山羊生产规模的现状分析入手，研究内蒙古绒山羊生产规模扩大的后果。重点分析了绒山羊养殖的增加对生态环境的影响，并估计出内蒙古草原对山羊的承载能力和羊绒最大产量。为内蒙古绒山羊生产规模的发展提出建议。     

传统屋脊上的文化浅析

中华民族是木文化的民族，寺庙、宫殿建筑是木结构建筑的颠峰代表作：大屋顶、斜坡面、深出檐、高翘角，脊吻、走兽，神奇的传说向世人展示了中华民族建筑文化方面的独特风貌。本文试图从正脊和垂脊上的吻和兽来探寻传统屋脊上的文化。     

文化对动物隐喻形成的决定性作用

动物隐喻是语言、文化和我们的概念系统相互作用的产物。动物隐喻是基于源域和目标域之间的相似性而激发形成。文化是动物隐喻的基础，它决定着动物隐喻的规模并塑造动物隐喻中作为源域的动物固定形象。     

黑龙江省畜产品出口发展战略

尽管黑龙江省畜牧业取得了突出的成绩,但黑龙江省畜牧业发展中仍存在一些亟待解决的问题,如,从业人员文化素质低,资金严重不足,畜牧业科技水平较低,畜牧业管理体制不协调等,这些问题的存在已经严重制约了黑龙江省畜产品的出口.黑龙江省的畜产品出口表现出明显的区域特点,在未来的发展中,必须在提高产品质量,发展绿色畜产品的基础上实现畜产品出口的扩大.
