Flooding,as a kind of disturbance events,occurred with higher and higherfrequency over the world.To investigate the effects of flooding disturbance ongrassland vegetation and the soil,a comparatively thorough study was conducted onAneurolepidium chinense grassland in Songnen plain,Northeast China.The studysite was located in Sanjiadian National Rangeland in the territory of Da'an city,Jilirprovince,which was partly flooded in 1998.On the study site,Several transectssubjected to different flooding durations and intensities were designed for thecomparative study among them on such aspects as vegetation characteristics,seedbanks,vegetative propagation of rhizomatous plants,distribution patterns ofpopulations,interspecific relations,and physio-chemical properties of soil.Theresults were as follows:(1)Of the functional group composition of the vegetation,with the elongation of the flooding duration or the increase of flooding severity,theratio of hygric and hygro-mesic plants increase,while that of mesic and mesoxericplants decrease,of Therophytes changed unimodally,of Geophytes increased,whileof Hemicryptophytes decreased.
为弄清草地植被及其土壤环境对水淹干扰的响应,在松嫩平原羊草草地1998年部分遭受水淹的吉林省大安市三家甸子草场内设置了经历不同水淹干扰持续时间和不同水淹强度的样带,并在这些样带之间从植被特征、种子库特征、根茎植物的营养繁殖性能、种群分布格局、种间关系及土壤的理化性质等多个方面展开对比研究,主要结果如下:(1)在植被的功能群组成中,随干扰强度的增加和水淹干扰持续时间的延长,湿生、湿中生类植物功能群的优势度比例基本上是逐渐增加的,中生、中旱生类植物功能群的优势度比例则逐渐减小,而一年生植物的优势度比例呈单峰型变化,地下芽植物比例增加,地面芽植物比例减小。

Results We discovered and confirmed that there were 17 different species of 1st intermediate host of in Paragonimus Jiangxi, covering 2 families and 3 genera, and 23 different species of 2nd intermediate host, covering 1 order, 1 family and 3 genera, 15 of which were reported to be new species by the authors. Furthermore, a new genus of Jiangxi Huananpotamon was built up, based on the assumption that Wuyi mountain range is the developing centre of Huananpotamon , and tend to spread out towards Jiulian mountain of Nanling mountain range adjacent to Guangdong Province and Luoxiao mountain range next to Hunan Province. In addition, Jiangxi Province freshwater crab order was created at the end of research, as well as a complete classification and retrieval table of its order and genus. The authors also proved that the advantageous stocks of freshwater crabs carrying encysted metacercaria of Jiangxi Paragonimus westermani were Sinopotamon fukiense and S.wanzaiense .

The proportion of rents that firms get depends on their network capability. This reveals the essential relationships between network resource, network rents and network capability: First of all, network rents come from the network resources. Furthermore, network rent is the representative of the competitive advantage and the value of the network resource. Second, network resource is the foundation of the network capability, the function of network capability is activated in the process of using network resource by firm. It enables the network resource to be a potential value resource of the competitive advantage. At last, network capability activates the network rents in the network resource, and make sure that the firm get the additional benefit;(4) the network capability can be classified as: network visioning capability, network constructing capability, network operating capability and network constructing capability. Some factors, such as maturity of IT, openness of culture, management system involved, experience of participation in network, have a positive effect on the network capability of the firm;(5) the impact of network capability on innovation performance is realized through knowledge transfer between network partners, namely, knowledge transfer is the mediator; and (6) the type of innovation network, exporation network or exploitation network, has moderator effect on the relationship of network capability and knowledge transfer, and network capability and innovation performance as well. In the exploration network, network constructing capability has more effect on the performance of the knowledge transfer and innovation. In the exploitation network, network operating capability has more effect on the performance of the knowledge transfer and innovation.
通过对创新网络环境下网络资源、网络租金和网络能力的概念界定和内涵分析,本研究辨析了三者之间以及它们与竞争优势之间的本质关系:首先,网络资源是网络租金的来源,而网络租金是企业竞争优势的表征,也是网络资源的价值体现;其次,网络资源是网络能力的基础,而网络能力在运用网络资源的过程中发挥其作用,实现了网络资源成为竞争优势源泉的内在价值;最后,网络能力激活了蕴涵在网络资源中的网络租金,并确定企业获得这种额外收益的份额,网络租金正是网络能力发挥作用的成果;(4)企业网络能力可以分成网络规划能力、网络配置能力、网络运作能力和网络占位能力四种,本研究的实证结果表明企业的IT成熟度、文化开放度、网络管理体系和网络活动经验都能够正向影响企业的网络能力水平,因而企业可以通过改善上述各种因素的水平来实现提升企业网络能力的水平;(5)企业网络能力对企业创新绩效的促进作用更多地是通过正向影响知识转移实现的,即知识转移在其中起到了中介作用;(6)创新网络的类型,即探索型创新网络和利用型创新网络,分别在网络配置能力和网络运作能力与知识转移之间的关系中,以及在网络配置能力和网络运作能力与创新绩效之间的关系中起到调节作用,在探索性创新网络中,企业的网络配置能力对提升企业获得的知识转移绩效和创新绩效更为重要;而在利用性创新网络中,企业的网络运作能力对提升企业获得的知识转移绩效和创新绩效更为重要。
