At the every relative momentary point of time time-space, the situation of difference spatial measurement of cosmic gravitation exceed cosmic space-energy follow the rise and fall of quantum spatial measurement, at original cosmic time-space set out, from 0 come to do not exceed the 1/2 spatial measurement of cosmic time-space, not smaller the 1/4 spatial measurement of cosmic time-space, come to do not symmetrically gradually belong to stabilization thus at reductively fluctuate, not can reversely strides across reach the stable state of 1/3 spatial measurement cosmic time-space maintain unchanging.

At a certain range, habitat loss and its spatial structure can benefit the control of the epidemic disease, which indicates the possibility of using human disturbance in habitat as a potential epidemic-control method in conservation.(6) Not only the quantity of habitat loss but also the spatial correlations of patch types caused by nonrandom habitat loss affect the invasion and transmission of disease. More fragmented landscape (high amount of habitat loss, low clustering of lost patches) hinders the parasitic infection, which also indicates that whether the spatial heterogeneity benefits or hinders the invasion is dependent on the considered ecological process.(7) Two components of the spatial heterogeneity (the amount and spatial autocorrelation of the lost habitat) form a trade-off in determining the host-parasite dynamics.(8) Within a certain range of habitat loss, host can counterbalance the positive and negative effects, and shows a rising tendency.(9) The epidemic is more likely to break out in the prey-predator system if only a small amount of habitat loss.(10) A highly aggregated distribution of species is a common behavioral strategy when dealing with habitat loss or other environmental stresses.(11) The parasite-host/prey-predator eco-epidemiological systems have the similar mechanism with the intraguild predation systems, and the predator acts as the intraguild predation, the infected prey acts as intraguild prey, and the susceptible prey acts as shared resource.(12) Species at the highest trophic level are no longer affected the most by habitat loss, which depend not only on the biological mechanism but also on the external environmental disturbances.

随着邻体数目的增加，病毒的感染力度变得更大而且在空间上形成聚集的波形；(5)生境破坏及其空间结构在一定范围内有利于疾病的控制，这暗示人为对生境的干扰可作为疾病控制的一个潜在方法；(6)生境破坏的数量以及不同类型生境的空间分布格局都显著地影响了寄生病毒的入侵和传播，生境破碎化程度越高(高丧失斑块的数量或低聚集程度)，将越有害于病毒的入侵和传播，这暗示了空间异质性是否有益于物种的入侵依赖于所考虑的生态过程；(7)由生境破坏引起的空间异质性的两个组分之间存在负偶联关系trade-off(8在适度的生境破坏范围内，宿主种群能够平衡生境破坏带来的正负两种效应并呈现增长趋势；(9)在捕食-食饵系统中，寄生感染病毒极有可能在生境破坏量较低时爆发；(10)物种在面临生境破坏或者其它环境压力时表现出更高的聚集分布策略；(11)寄生-宿主/食饵-捕食生态传染病系统与共位捕食食物网结构具有相似的生物机制，其中捕食者扮演共位捕食者的角色，已感染食饵作为共位食饵，易感染食饵扮作共同消耗的资源；(12)位于最高营养级水平的种群对生境破坏的响应不一定是最敏感的，这不仅依赖于内在的生物机制同时也依赖于外在的环境干扰。

However, it can only implement the limited operation to the spatial objects, cannot carry on transformation, index, interlink age and excavation to the spatial data, and hard integrate other information with combining map variable to set up and analysis new variable. Meanwhile, relational model in the traditional DBMS and the object- oriented modeling do not completely suit the spatial application domain. The relational model can handle topological relation well, but shows inabilities to that complicated level crossing the spatial region. Object-oriented model using software method based on the principle of the customer defined data type supports the abstract data type, especially spatial abstract data type, and possesses polymorphism and inheritances, and it can deal with topological and the layer relation, but hardly processes important continuous phenomenon in space.

GIS是当今操作有关空间信息的成熟工具和技术，但其只能对空间对象进行有限的操作，不能对空间数据进行变换、索引、链接和挖掘，难以集成其他信息来构建和分析新变量；而传统数据库管理模型中的关系模型和面向对象建模也不完全适合空间应用这一领域，关系模型能够较好地处理拓扑关系，但对表示横跨空间区域的复杂层次却无能为力；面向对象模型的软件方法支持抽象数据类型，特别是空间抽象数据类型，具有继承性和多态性，能够处理拓扑和层次关系，但难以处理空间中重要的连续性现象。

In the paper, the author establish the evaluation system between the "two planing" based on the reintegrating and perfecting of the spatial planning system in our country and the reforming requirement to the sub-planning of spatial planing—the "two planing" from the change of precondition of the making of planning, through which to indicate the complicated contradictive relation between the " two planning ", to quantificationally appraise the present maturity degree and to guide the developing direction to the " two planning ". the author try to find out the two planning's reform direction and emphases in aftertime though out putting the evaluation system between the "two planing" into the sample city regional practice. In the end of this paper, the division and the collaboration mechanisms of the "two planing" have been discussed under the future perfect spatial planning system, also the division and the collaboration two strategies of the "two planing" based on current situation development of planning and the future perfect spatial planning system have been pointed out.

Through detailed analysis of the concept and nature of the "megalopolis", this paper discusses the relationship and influence factors between change of the industrial and urban and township spatial structures of the Yangtze Delta Area and argues that: i the two highly modernized networks (infrastructure networks and the market and industrial organization networks) based on functional division of labor between individual cities possess crucial importance in facilitating change and upgrade of the industrial structure on one side and sustained optimization of the organizational pattern of the urban and township spatial structure on the other; ii in the light of the Yangtze Delta Area, influence factors in promoting positive corresponding states between change of the industrial structure and urban and township spatial structure are concerned with development level of the first place city, rational and orderly hierarchy of the urban and township system and, meanwhile, up-to-dateness of the city networks.

本文以长三角为研究地区，对产业结构演进与城镇空间结构的对应关系和影响要素进行了探讨。据此认为，基于城市功能定位和合理分工基础之上的高度现代化的两大网络（基础设施网络、市场体系和产业组织网络）是推进产业结构不断演进和升级的重要条件，也是推动城镇空间结构和组织模式持续优化的着力点和主要抓手；促进产业结构演进与城镇空间结构对应的影响要素主要包括：首位城市的发达程度、城市间合理和有序的层级关系、城市体系网络的现代化程度。

By starting with the basic theory of metropolis ring spatial development and drawing the experience of domestic and foreign metropolis ring, the paper makes a discussion on efficiency of metropolis ring pattern, development phases and spatial structure. It points out the three main phases of metropolis ring development—rudiment, growth and autumn. From the spatial structure, the paper stresses that metropolis ring has the features of "ring and layer", the size of the "ring and layer" has the direct ratio with city size, convenient degree of external transportation and city radiant intensity. It owns the idea that adjustment and control of metropolis ring spatial development should reflect the following concepts, including globalization, regional integrated harmony, views of scientific development, harmonious society, consultative city planning, people-oriented principle, guided city planning and responded city planning.

从都市圈空间发展的基础理论入手，借鉴国内外都市圈发展的经验，本文对都市圈模式效应、发展阶段和空间结构进行了探讨，认为都市圈发展阶段主要分雏形期、成长期和成熟期三个阶段；从空间结构看，都市圈具有"圈层式"的特征，圈层的大小与城市规模、城市对外交通的便利程度、城市对外辐射强度成正比；都市圈空间发展调控应体现全球一体化理念、区域整体协调理念、科学发展观理念、构建和谐社会理念、协商规划理念、以人为本理念、导向型规划理念和规划应变性理念。

Traditional method to coarsen and disperse the spatial data to lower administer unit in order to let spatial data be agreement to statistic data loses some spatial information. The comprehensive indexes got from these data of course cannot express the land-use spatial differentiation regularity well.
