The characteristics of geographical spatial thought include : 1 ) forming mental pictures at sight of words , 2 ) corresponding speculation about spatial graphs and 3 ) dynamic relative speculation about space 地理空间思维一般具有以下特点：见文生图；空间图形的对应思辩；空间的动态联系思辩。

The difformity of these graphs reflected the diversity of their formative mechanism , behavior character and development phase . thus the research for geography spatial graph could educe the evolvement law 图形的千差万别反映了它们成因机制、行为特征及演化差异的信息，对地理空间图形的研究可以反演空间事物的分异演化规律。

Patch of dissimilar land use types had different spatial graph character , and patch of the same land use type also exhibited different spatial shape in different evolvement phase or in different environment 不同土地利用类型斑块有不同的空间图形特征，同一土地利用类型斑块在不同演化阶段或处于不同环境中其空间形状也有差异。

Gis is a powerful tool which can process spatial maps and related attributes , and has been widely applied to many professional fields , this paper mainly discusses some applications of gis in transportation field Gis是一种强有力的、同时具备处理空间图形信息和属性数据信息能力的工具，它已被广泛地应用于许多专业领域，本文主要讨论了其在交通领域内的一些应用情况。

In actual gis applications , both integrated gis platforms and specialized gis platforms are in demand . to satisfied with a special gis applications which has few spatial data , simple spatial objects , few demand for map ability , more demand for distance data access and more demand for multi - user cooperation ( i . e . : apply gis to telecomm resource management , electric power capital management , land property right management etc . ) , a spatial data model based on constructed point set storage is presented 针对空间信息数据量较小、空间对象相对简单、图形功能要求不高，但对远程数据访问、多用户并发操作等功能要求较高的一类特殊应用(如电信资源管理、电力资产管理和宗地管理等) ，本文提出了一个基于构造点集(用于空间图形对象构造的样本点的集合，简称为构造点集)的全关系型空间数据模型，来满足该类应用的特殊要求。
