    随着全球经济一体化进程的加快,民用航空业在汇集客流、物流等方面对经济发展起着重要的促进作用。同时,随着航空业市场竞争的加剧,使得积极探索航空附属收益的空间更具价值。机场停车场作为机场服务的必要基础设施,不仅是机场运营管理的重点环节,更因其收益潜力将成为机场非航空收入的重要增长点。因此,研究机场的停车场收益问题,具有十分重要的意义。 本文基于收益管理的视角,首先介绍X机场停车场目前的收益情况,然后从该机场停车收费对旅客停车需求选择的影响进行分析,对停车收费和旅客开车前往X机场的选择行为模型进行了探讨,而后构建停车定价策略与停车场收入的关系模型,并运用时间序列的自回归模型拟合车流,预测车流量,并...Aviation Industry plays an important role in economic development in the process of Economic Globalization due to its natural advantages in Concentrating of Passengers Flow and Logistics.

    Spatial distribution and abundance of small fishes were studied in autumn 2007 in the Xiaosihai Lake, a shallow lake along the middle reach of the Changjiang (Yangtze) River. Based on the plant cover, the lake was divided into three major habitats: Myriophyllum spicatum habitat (MS habitat), Trapa bispinosa habitat (TB habitat), and non-vegetation habitat (NV habitat). A modified pop-net was used for quantitative sampling of small fishes in the three habitats, and the Zippin’s removal method was used for estimating densities of the small fishes. A total of 13 species belonging to 5 families were collected, with 11 species in MS habitat, 7 species in TB habitat, and 5 species in NV habitat. Habitat type had significant effect on the spatial distribution of small fishes. The Shannon-Wiener diversity index in the MS, TB and NV habitats were 1.28, 0.56 and 0.54, respectively. The total density and biomass of small fishes were significantly higher in the MS habitat (13.68 ind/m2 and 4.44 g/m2) than in the TB habitat (1.41 ind/m2 and 0.54 g/m2) and the NV habitat (1.08 ind/m2 and 0.40 g/m2), and were not significantly different between the TB habitat and the NV habitat. Water depth had no significant effect on spatial distribution of the small fishes. It was suggested that vegetation type played an important role in habitat selectivity of small fishes, and the presence of submersed vegetation should be of significance in the conservation of small fish diversity

    运用8种网目规格的成套浮性刺网作为鱼类采样工具,于2005年夏季在长江中游浅水草型湖泊牛山湖进行鱼类定量采样,通过比较不同茂密程度黄丝草生境中的小型鱼类组成、数量和大小结构,探讨此类湖泊小型鱼类的空间分布特征及其与沉水植被的关系.采样期间共捕获13种1124尾鱼,依据其等级丰度和出现频次,和红鳍原!为该湖优势上层小型鱼类.在调查的沉水植物生物量范围内,鱼类物种丰富度和Shannon多样性指数与沉水植物生物量之间呈现倒抛物线关系;两种优势小型鱼类的种群丰度均与沉水植物生物量有着显著的线性正相关关系,且其平均个体大小在裸地生境较高、沉水植被茂密区较低,幼鱼更倾向群聚于厚密的黄丝草生境中;其他生境因子(水深和离岸距离)对和红鳍原!空间分布的影响不显著.黄丝草植被生境是牛山湖两种优势小型鱼类的重要保护生境,应加强对黄丝草等沉水植被的保护及恢复

    长江中游三个湖泊中华绒螯蟹生长变化研究

    选择长江中游的牛山湖、武湖和东汤逊湖三个典型的河蟹养殖湖区作为研究地点,从2009年2月起逐月调查湖泊放流河蟹体重和壳宽的生长变化,并同时记录投喂管理情况和收集试验湖区的水化特征及底栖生物资源状况。调查发现,河蟹在4、5、6月特定生长率最大,此时为河蟹生长的高峰期。在三个湖区间,生长有显著性差异,在收获季节,武湖河蟹的平均壳宽和体重均显著性大于另外两个湖区(P0.05);这种情形可能主要与为湖泊的天然饵料资源的种类和丰度有关

    兽药产品质量不仅仅关系到畜禽等动物疫病的防治、畜禽产品质量安全和养殖业的持续稳定健康发展问题,还关系到人类的生存环境、关系到人类的健康。我国现拥有1600多家兽药生产企业,2万多个品种,10万多个批准文号,7万多经销点。但是由缺乏互联网的手段,兽药产品无法实现数据互联互通,使得兽药产品一直都处在监管的薄弱环节。因此,兽药监管部门有必要采取信息化等积极措施,利用信息技术逐步建立覆盖全国的兽药监管信息系统,实现全方位、可追溯的有效监管,为兽药监管部门提供强有力技术保障,提升整个兽药监管系统的兽药质量综合监控能力。 以软件工程中的瀑布模型为设计主线,本论文较为详细地介绍了兽药产品追溯信息系统的业务...The quality of veterinary drug products is directly related to the prevention and control of animal diseases, the quality and safety of animal products,the sustainable development of breeding industry.

    我国的社区建设是在社会转型的背景下进行的,在传统的单位制逐渐瓦解的情况下,社区治理呈现出行政化的导向。虽然行政化的社区管理方式能够弥补单位制解体带来的社会整合问题,但是却严重阻碍了社区自治的发展。居民的社区参与作为社区自治的一个重要方面,受到了许多因素的影响,其中社区社会资本就是一个重要的因素。本研究将从居民参与到社区建设的影响因素出发,重点探究社区社会资本对于居民社区参与的影响,为我国城市社区目前所面临的治理困境提供新的思考。 本研究以2014年在厦门市海沧区所进行的社区居民参与社区活动的问卷调查为基础,探讨了居民的个体性因素以及三个维度社区社会资本对于社区居民是否参与社区建设活动以及对于...China's community building is carried out in the context of social transformation.

    七种捕食性鱼类对中华绒螯蟹幼蟹捕食风险的评估

    分别以鲤、鳜、斑点叉尾、黄颡鱼、瓦氏黄颡鱼、大口鲇和乌鳢作为捕食者,以中华绒螯蟹幼蟹作为猎物,在室内水泥池(2.4 m3)进行捕食试验。以日捕获率和日摄食率为指标,评估这些鱼类对幼蟹的捕食作用和危害程度,为提高湖泊幼蟹放流效果、建立蟹—鱼复合的优质高效养殖模式提供科学依据。在幼蟹完全暴露的条件下,经过多次(至少9次)重复的试验(短期1d和长期7d),鳜对不同大小的硬壳和软壳(刚蜕壳的)幼蟹没有任何捕食作用;黄颡鱼对硬壳和软壳幼蟹也没有捕食作用,但还需做进一步观察;虽然鲤、瓦氏黄颡鱼对硬壳蟹的捕获率低,但对软壳的幼蟹有较大的危害性,对幼蟹的日摄食率分别为0.070%、0.012%;大口鲇、斑点叉尾、乌鳢对幼蟹具有较强的捕食能力,对幼蟹的日摄食率分别为0.122%、0.188%和0.284%。根据这些研究结果,可以建议:(1)在池塘和湖泊河蟹养殖中,完全可以将鳜作为套养或混养对象,以期提高养殖效益;(2)在河蟹放养的湖泊,需要抑制乌鳢和大口鲇种群,适当减少鲤和瓦氏黄颡鱼丰度,以期减少这些鱼类的捕食作用,提高幼蟹存活率;(3)在河蟹养殖池塘,不能放养乌鳢、大口鲇、斑点叉尾、瓦氏黄颡鱼和鲤

    Abstract in Chinese: 作为明清时期十大商帮之首,晋商以其精湛的商业经营技巧、票号间的规模经营以及敏锐的商业经营意识而著称,内在的诚信经营意识也是晋商成功的重要因素,而这种精神或信仰恰是我国市场经济高速发展过程中所欠缺的。文章旨在通过对于晋商诚信道德形成原因、价值原则及保障机制的系统分析基础上重点提出当前我国诚信体系建设的有益建议。Abstract in English: Jin merchants can serve as the top of ten business groups in the Ming and Qing dynasties, its success not only lies in the latter superb business skills, scale operation between Banks and sensitive business sense, but at the same time, its internal credit management consciousness is also an important factor to business success. And this is exactly what spirit or faith in the process of the market economy high speed development of our country lacks. The thesis aims to what bases on the systematic analysis of Jin merchants’ ethics moral formation, value principle and guarantee mechanism to provide beneficial suggestions for the construction of our country's credit system.
