The Study of Enterprises Procurement Based on Internet

本文研究由第三方中介机构按行业建立与企业内部信息系统集成的联网采购网站,实现传统的企业供销流程及采购管理向网上采购和在线采购管理转移,借助互联网的快捷、廉价、数字化的特性,配合以大型数据库强大的计算、存储、查询功能,建立起一套适合于中国国情的全新的网上采购模式.This paper investigates how to establish industry website of procurement which integrates with company's information systems by the third-party integrator. Such kind of website can transfer supply and sale's process of traditional enterprises to procurement and management of procurement on internet. In advantage of the fast, cheap and digital properties of internet, combined with the powerful function of computing, storage and look up of large database, we can create a new approach of procurement on internet which is suitable for Chinese situation

Some Suggestions about Manufacturing Corporate Informationization

目前,我国企业广泛地应用电子信息技术,大力推进企业经营、管理、研发、制造信息化;以实现管理科学化、向管理要效益为宗旨,建立符合市场经济规律的、科学的企业信息系统,可以有效地提高企业核心竞争力,使我国在加入WTO之后,企业在国际化竞争中更具实力,信息化是现代企业的必由之路.Today, in China, information technology is widely used in business management, which has quickened the informationization of business operation, management, R & D and production. The construction of a scientific decision making system in line with the law of market economy, in which the enterprises are seeking high returns mainly through scientific management, will effectively enhance the competitiveness of the enterprises as well as the comprehensive national strength. In particular, it will make China more competitive in the world market after its WTO entry. Therefore informationization is an unavoidable choice for the modern enterprises

In this paper, we compare these three models, and reveal the model- (e-marketplace) is the best one. E- marketplace represent the trend of global trade methods, and will becom WTO in the field of e commerce(eWTO)

Dwarf Reasons of Mangrove Plant Kandelia obovata in Shancheng Bay,Fujian

明确了低温和淹水对分布在福建沙埕湾(27°17′N,120°18′E)的红树植物秋茄(Kandelia obovata)生长的直接作用方式,探讨了纬度较高地区秋茄矮化的原因,以期在全球气候变暖影响下,为中国纬度较高地区红树林人工造林提供理论指导。通过调查福建省福鼎市沙埕湾高潮淹水线上下秋茄末端小枝生长状况、不同相对高程秋茄高度以及淹水线上下温度的实时监测,研究低温和淹水对纬度较高地区秋茄生长的影响。结果表明,低温对该地区秋茄淹水线以上部分影响显著,主要表现在枝条和叶片受低温胁迫严重,生长缓慢,顶端顶芽大量枯死;相对高程与秋茄的高度显著负相关;淹水降低了秋茄叶片的光合能力。淹水降低了低温对沙埕湾秋茄生长的胁迫程度,且对秋茄向上生长有一定的促进作用,但是在低温和强潮差的影响下,在纬度较高地区很难营造出高大繁茂的秋茄林。This study explicated the ways that how low temperature and water flooding had directly influenced the growth of mangrove plant Kandelia obovata distributed in Shacheng Bay(27°17′N,120°18′E), Fujian province where latitude is higher than 25°N and discussed the dwarf reasons of mangrove plants in higher latitude.Under the influence of global warming, it can provide the theoretical guidance for mangrove afforestation in higher-latitude areas in China. Through the survey of the growth status of the shoots of Kandelia obovata and the real-time monitoring of temperature under and above the flooded waterline and the tree height at different relative elevation for Kandelia obovata in Shacheng Bay, how low temperature and flooding influenced the growth of Kandelia obovata was studied. The results showed that low temperature had significant effects on Kandelia obovata growth, especially the part above the flooded waterline, mainly displayed in the branches and leaves of Kandelia obovata were strongly subjected to the low temperature stress, growing slowly, the bud withering at the top of crown; there was significant negative correlation between the Kandelia obovata height and the relative elevation; flooding reduced the photosynthetic capacity of Kandelia obovata leaves. To a certain extent, flooding could reduce the low temperature stress impact on the growth of Kandelia obovata and promote the upward growth of Kandelia obovata in higher-latitude area. But under the influence of low temperature and strong tidal range, a tall Kandelia obovata forest could not be built in higher-latitude regions.国家重点研发计划项目课题(2016YFC0502904);; 广西科学院基本科研业务费项目(13YJ25HS04和12YJ25HS15)资
