面向多应用系统的位置公共服务(LBCS)模式研究与平台设计

当前的LBS应用系统多采用独立构建方式,将LBS通用服务功能与应用系统相关功能集成,使系统内部耦合程度较高,虽然能够保证应用系统的完整性,但导致LBS通用服务功能难以共享,造成系统的扩展性差以及数据、计算资源的浪费。该文探索了面向多应用系统的位置公共服务(LBCS)的服务模式与系统体系结构。基于这种服务模式,位置服务系统将由两大部件构成:LBS公共服务平台和专业应用系统,且LBS公共服务平台能被多个应用系统使用。     

ECOLOGICALLY STRATEGIC POINTS IN LANDSCAPE AND SURFACE MODEL

Various processes occur across a landscape, including ecological processes such as the movement of species, the flow of nutrients, the spread of fire and other disturbances, and the diffusion of pollutants, economic processes such as land conversion for agricultural production, marketing of new product, transportation and immigration; political and diplomatic processes such as the construction of political influence sphere at local, national and global scale. At the fact of limited space and resources on the surface of the earth, a generic issue regarding these processes across the landscapes is: how to control (promote or retard) the processes efficiently, namely using less energy and space for a bigger influence sphere. The overall assumption for this issue is that, there are some positions and portion in a landscape that may have critical influence on a certain process across the landscape. These critical positions in a landscape are called strategic points. Occupancy of these strategic points may give a process the momentum of controlling and covering the landscape more effectively, due to their quality of; Initiative, occupancy of these points may give the process the advantage of leading the game; Co-ordlnation, occupancy of these points may give the process the advantage of forming an overall influence sphere; Efficiency, occupancy of these points may give the process the advantage of having a bigger coverage of the landscape while costing less energy. By identifying and using these critical positions and portions in the landscape, therefore, may unproportionately increase the efficiency of controlling this process. It is further assumed that, in order to take control of the landscape, the process has to overcome a certain resistance. A resistance surface can therefore visualize the dynamics of the process itself. The resistance surface resembles a topographic surface, indicating where the process (flow) diverges or converges. It is, therefore, possible to identify strategically important positions or portions in a landscape that may have important influence on the dynamics of the process. Assuming species movement across a landscape is a competitive gaming process of control and coverage against some resistance, this paper discusses a methodology of identifying strategic points according to the properties of resistance surfaces which resembles a gaming board as well as a topographic surface. Three types of resistance surfaces are discussed: The archipelago type: where lower resistance islands are surrounded by higher resistance matrix, representing such landscapes as agricultural fields dotted with native forest patches. The network type: where the lower resistance portions form a linear network surrounded by higher resistance matrix. The plateau type: where, areas with higher resistance are surrounded by lower resistance matrix. Accordingly, five types of strategic points are identified in terms of their locations. They are strategic points at saddle points , at intersections, at the center, at an edge and at a corner. Strategic points for biodivershy conservation are minimax points in a given resistance surface associated with the dispersibility of a certain species. A case study is used to illustrate the methodology. The rules leading to the strategic points are largely hypothetical, though supported by a limited number of observations. This approach may provide a framework and a new model of thinking for field observations of landscape ecology as well as landscape change.     

基于花卉产业链价值空间分配的区域创新

产业链中的价值的分配反映区域创新能力的差异,价值集聚区更具创新和竞争力.以鲜切花为特色的云南省的花卉产业有着更多的骄傲,但是,基于产业链的价值分配显示出诸多问题,在鲜切花出口、花卉装饰、种球和花文化的系列新产业链中,云南省都不是价值的富集区,即并非最大受益者.与其它省比较,云南省花卉产业的狭隘思维和组织协调能力,反映在区域花卉产业价值集聚的促进作用不足.
