缓冲区分析 meaning in Chinese
buffer
Examples
- Buffer analysis is one of the several important analysis functions of geographical information system ( gis )
摘要缓冲区分析是地理信息系统重要的空间分析功能之一。 - With utpgis , transportation - relevant temporal data , which include road network , traffic zones and intersections temporal data , can be updated , managed and displayed and dynamic display of trip path and buffer analysis are also implemented
其中包括道路网时态数据、交通小区时态数据、交叉口时态数据的更新显示和管理。系统还实现了出行路径的动态显示功能及缓冲区分析功能。 - Based on the original data of tm in 1988 , 1992 and 1998 , then after some processing and analysis , the author have the thematic data of land - use by interpretation . on the basis of them , the author made the analysis of land - use for this area based on the spacial analysis of gis and the method of comparison between result of land - use classification as follows : the method of aggregating analysis , the analysis of urbanization , the analysis of the transformation rate of cultivated land , the analysis of the driving force of land - use change and the sustainable use of land . the conclusions may be demonstrated below : the cultivated land decreases with the patchs fragment ; road spreads radialy surround second - ring road ; the urban land expands quickly toward southwest along the major roads and be concentrative . rural land and industry increse rapidly with dispersing ; 0thers change slowly . the major driving forces of land - use change in this area are the rapid expansion of urban and rapid growth of population , foreign investment and the development of tertiary industry which was based upon the real estate . according the trendency of land - use change , the author consider that we must insist on the way of the sustainable use of land based on protecting the cultivated land
在此基础上，应用分类结果比较法，在gis各种空间分析功能(几何量算、统计分析、叠加分析及缓冲区分析)的支持下，对该区土地利用变化进行了如下分析：土地利用综合分析、城市化进程分析、耕地转化率分析、土地利用变化因素分析及土地的可持续利用分析。结果表明：该区土地利用变化主要表现为耕地大量减少，斑块破碎化；交通用地沿二环线呈放射状向四周扩展；城镇用地沿交通干线向西南方向扩张迅速，用地趋于集中；农村居民点和工矿业用地增加，用地趋于分散；其它用地变化较慢。这一用地变化的主导因素是城镇用地扩展快、人口增长迅速、外资的大量投入及以房地产为主的第三产业的快速发展。 - Main technic of giss webgiso thus function modules architecture and network topological structure are confirmed webgis system implements the basic function of electronical map , such as map zoonu pan , and the abundant query of geograph and database by using maplnfo mapxtreme for java as map server and jsp . , java technico this system also can implement the routing of linesx analysing of buffer and so on0 this paper advances storage model of roads and pipelines topology data , efficiently solves the maintenace problem of network topology data of webgis and implements the shortest path algorathm based on webgis by improving it0 the system has better opening by suppling database interface of map ? the system has perfect on - line help and user forum and favorable interfaces and implementation of this system makes fundament for the further research of webgiso
本系统利用mapinfomapxtremeforjava作为地图服务器，采用jsp和java技术，实现了基于webgis的电子地图的缩放、漫游等基本功能，并具有丰富的图文定位查询功能；实现线路路由、缓冲区分析等辅助决策功能；构建了道路管线网络拓扑数据的存储模型，有效地解决了基于webgis的网络拓扑数据的维护问题；对dijkstra算法进行了一些改进，实现了基于webgis的最短路径算法；本系统提供了电子地图数据库接口，使本系统具有很好的开放性和通用性； webgis系统软件具有完善的在线帮助和用户交流论坛，人机界面友好。 - Based on the landscape remote sensing mapping , buffer zone analysis and total variation index calculation of landscape structure for two neighbored buffer zones were used to divide the natural landscape and human impacted landscape in wolong natural reserve . the spatial distribution characteristics of human impacted landscape were also studied
在景观遥感制图的基础上，利用缓冲区分析和相邻缓冲区的景观结构总体变异系数方法对卧自然保护区进行了自然景观和人为影响景观的分割研究，并对人为影响景观的空间分布特征进行了分析。
