模糊区域拓扑关系模型

拓扑关系是地理信息系统中空间要素之间最基本也是最重要的关系之一，是进行绝大多数空间查询和分析的基础。非模糊空间要素之间的拓扑关系在一般拓扑学等理论的基础上已有相关的模型和描述，并在实践中得到广泛的应用，如何建立模糊空间要素这间的拓扑关系是建立模糊要素地理信息系统的基础。该文在模糊扑扑学的基础上提出了模糊区域的定义，建立了用于分析模糊区域之间拓扑关系的理论和模型，提出了4*4-intersection模型拓扑关系矩阵，并分析了不同拓扑关系矩阵对于非模糊区域之间、模糊区域之间建立拓扑关系的区别和联系，最后采和不同公式对模糊区域之间的关系进行了系统的描述。     

基于粗糙集的不确定区域RCC拓扑关系研究

基于粗糙集定义了粗糙区域和粗糙区域的上、下近似区域,提出两种基于上、下近似区域表示粗糙区域拓扑关系的方法。一种方法用上、下近似区域的连接关系表达粗糙区域拓扑关系,得出两个粗糙区域之间的6种拓扑关系,并进一步利用上、下近似区域的RCC5关系表达粗糙区域之间的拓扑关系,得出两个粗糙区域之间的51种拓扑关系,然后分析两种表达之间的联系。另一种方法扩展RCC5模型,首先定义三值逻辑的部分关系≤和补运算~,然后用三值逻辑三元组(X≤Y,X≤~Y,Y≤X)描述两个粗糙区域X和Y的拓扑关系,并给出可能的8种拓扑关系。     

基于等宽ε-带的三维线-线对象不确定性拓扑关系描述与判别方法

三维空间下不确定性对象拓扑关系是研究三维GIS中不确定性问题的基础。该文将二维平面直线不确定性的思想引入到三维空间,基于二维平面ε-带自旋转构建三维拓展包络体,表达不确定性三维线对象的置信区域。在对不确定性三维线对象进行描述的基础上,对不确定性线-线对象各部分之间的交集程度提出了一种定量化分析方法;通过对交集程度的度量,将三维空间下不确定性线-线拓扑关系用这些度量组成的空间向量表达;结合9I模型确定的参考空间关系向量理论,逐一考察度量化空间关系向量与参考空间关系向量之间的相关度,提出三维空间下不确定性线-线对象之间拓扑关系的描述模型,通过定量化分析方法对其空间拓扑关系进行判别。实验结果表明,该方法具备一定的可行性,可为不确定性问题的探讨提供科学依据。

一种基于对象的CSG-BR三维数据模型构建方法

在CSG-BR三维模型的基础上提出一种基于对象的CSG-BR三维数据模型构建方法.将地理实体按照CSG-BR三维模型的要求进行抽象、分解和组织,并把最小地理实体的几何特征、属性信息等相关信息进行对象封装,用边界表示法和结构实体几何表示法组织地理空间对象信息,建立各对象之间的语义关系.利用VRML对OCSG-BR数据进行三维可视化,实现了复杂三维空间数据及其相互间复杂关系的集成组织和管理,为对象化三维模型构建提供一种新方法.     

时间粒度对地理事件线性时间拓扑关系影响研究

时间尺度是时空数据模型中重要的要素,决定着对地理信息刻画和描述的详细程度,在时空数据库中,时间粒度对于时空拓扑关系描述具有决定性的影响。该文对时间的基本元素进行了形式化定义,在数轴上把时间基于集合论划分为3部分,并对两个时间要素划分的集合求交,从而建立地理事件间的线性时间拓扑关系形式化描述的9交模型,在此基础上探讨了时间粒度变化对地理事件间线性时间拓扑关系的影响,并进行了实例分析。

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.
