The procedure of the analysis is as follows :first,the digital road map was made based on the paper map ofFangshan,southwest Beijing,andthefire distribution map was made byinputingthefire points collected withGPSinto the GIS.The road connectivity was obtained using the Axwoman to drawlines along the roads.Buffers onthe lines within a distance of 1 000m were made,and the curver fitting was analyzed between the fire numbers and the road connectivity.

首先对房山区的纸质地形图进行扫描，制作房山的道路分布专题图，并将GPS采集的林火火点位置转入ArcView GIS，制作林火火点位置图；用Axwoman扩展模块勾绘了道路，进行了道路连通度的分析，并以勾绘的连通线作了1 000 m的缓冲分析；以连通度与相应的缓冲区内的林火火点数作了拟合分析。

The soil erodibilities are compared and appraised for the majority of the soil types in Ningxia. The method published by D. W. Fryrear et al is adopted to calculate erodible fractions for the soils in Ningxia. The erodibilities of main soil types are compared and analyzed. Spatial distribution of soil erodibilities in the region can be perceived on the Map of Ningxia Soil Erodibility. The map is based on the digitized map of soil types of the all region by means of the geographical information system of Region Manager. Evaluation results show that erodible soils occupy a large portion of the total area of the region.(3) The third task is evaluation of effects of human activities for farming on soil erodibility. Tillage and cultivation can alter soil properties. The paper, based on the discussion on the characteristics of farmland suffering wind erosion in the region, analyzes the contents and intensities of farming disturbing surface soil. Emphasis is paid on the effect of farming on erodibilities of each type of soil.

W Fryrear等人的计算土壤可蚀部分含量的方程，此方程的自变量包括土壤有机质、碳酸钙、沙粒含量、沙粘比，计算了宁夏主要土壤类型表层的可蚀含量，进而比较它们的可蚀性，并以宁夏土壤分布图为底图用地理信息系统建立了宁夏土壤风蚀数据库，完成了宁夏土壤可蚀性图，评价结果显示宁夏地区主要的土壤类型较容易遭受风蚀；（3）农业经营对土壤风蚀的影响及其评价，在分析宁夏农业土壤遭受风蚀特征的基础上，首先讨论了农业活动对土壤理化性质的干扰，评价主要耕作栽培措施对土壤风蚀的影响，选取粗糙度、表面结皮、可蚀颗粒含量、留茬和有效时间为指标，用打分方法作了评价。

Place the hair-line along the north-south lineon the map. Turn map and compass until the compass needle points inexactly the same direction as both lines. Your map is now oriented.

将指南针上正北的刻度线与地图上的南北向的方格线对齐，同时转动地图和上面的指南针，直到指南针的指针准确地指向刻度盘上的正北方向时，你的地图便可以正确使用了。

The orthograph map is a new map which integrated by the remotely sensed image and the simplified topographic map, in the digital regional geological survey, the orthograph may be regarded the important information resources of geo-survey, the handy geo-maps of geo-workers outside and the geo-carriers of geological features.

正射遥感影像地图是遥感影像与简化地形图复合而成的一种新图，在数字区调中，正射遥感影像地图可以作为地质填图的数据采集的重要信息源、区调地质测量的野外工作手图以及区域地质等要素的载体。

When digital map symbolizes on the screen, we call it electric map, which has the essential function of papery map.

电子地图具有地图的内涵，是数字地图在计算机屏幕上的符号化显示。

It can edit the disaster map element selected including of adding ,querying propertiy data,zooming out,zooming in the map element and so on..systemic establishing solves the segregative fact between the geography position of disaster point and the propertiy data.lt unites them,realizes the mutual consult between the map and data,infinitely increasing the work efficiency.

可以对选择的灾害图元进行编辑，包括对应属性数据的入库、查询、图元的放大、缩小等。系统的建立较好地解决了灾害点地理位置与其属性数据相分离的事实，它将二者统一起来，实现了图数互查，极大的提高了工作效率。

According to the methodology and technology of SOTER at a scale of 1∶1 000 000,a digital spatial database and a simple attribute database at a scale of 1∶200 000 was established in the south of Jiangsu province by integrating relief map, geology map and soil map with Arc/info software.

现有的土壤与地形资料在区域地理与环境研究中是必不可少的，而这些资料经常不能被充分地利用，主要原因是其信息的表达方式很落后-它们常常是零散的、不全面的，并且经常缺乏资源分布的空间与时间序列的信息。

The investigations in this thesis focus on several aspects as follows: We investigate the method that how to produce permutation matrix by using chaotic map, and get the method of image permutation based on chaotic map. This method can make original image to unorderly image to protect the true content of image. We investigate gray level mix function, and put forward a gray level mix function based on chaotic map. Because this function has chaotic characteristics, the image dealed with this function has very uniform histogram. Aiming at the contradiction between error robust and security on image encryption, we put forward a kind of gray level mix function including diffusion mechanism.

本文的研究工作主要集中在以下几方面：研究了如何利用混沌映射产生置乱矩阵的方法，给出了基于混沌的数字图像置乱方法，该方法能够将原始图像变成面目全非的杂乱图像，从而保护了数字图像的真实内容；研究了灰级混合函数，提出了基于混沌的灰级混合函数，由于该函数具有混沌特性，所以经过该函数处理后的图像具有非常均衡的灰级直方图；针对图像加密的错误鲁棒性与安全性之间的矛盾，提出了一种含有扩散机制的灰级混合函数。
