【摘要】 地球表面约1／4是山地,全世界有1／10的人口居住在山地,而约l／2人口的生活依靠山地资源。可见山地是地球生命支撑体系的重要组成部分,对维系人类生存与发展以及改善人类生存环境质量起着重要的作用。而近年来对山地的过度开发,已引发了一系列生态环境问题,严重制约着区域经济的发展步伐。以山地环境要素中的土壤作为一个切入点,利用地学信息图谱和地理信息系统技术研究山地土壤垂直带的分布、变化规律,将有助于反演山地环境的变化、预测其未来的发展趋势,为经济与社会可持续发展的规划决策提供科学依据和具体结论。地学信息图谱是一种将地球信息经过图形思维与抽象概括,并以计算机多维动态可视化技术显示地球系统几个要素和现象的宏观、中观及微观的时空变化规律的理论方法。地理信息系统则是一种存储、处理、查询、分析各种地球空间信息的技术手段。两者有机结合可优势互补,对于土壤垂直带的研究具有重要的现实意义,经过地学认知与空间模型的深入分析研究,有利于形成对垂直带更深层次的认识。本研究在前人研究成果的基础上,以云南这一地貌类型复杂、山地特征典型的省份作为研究区域,构建了土壤垂直带的数据存储结构,实现了土壤垂直带数字化显示,发现其在地域上分布具有纬向阶梯递增和经向递增的规律。接着根据土壤垂直带谱的数据特点、应用范围等,利用Geodatabase、ArcGIS Engine9.2和C#建立了云南山地土壤垂直带信息系统,实现了带谱图与空间位置的动态链接,可实时、高效查询相关信息。由于水平所限,加之时间、数据不足,对于带谱的图形计算及知识发现和数据挖掘未做深入研究,这将是下一步研究工作中需要加强和提升的地方。更多还原

【Abstract】 Approximately one quarter of the land on earth surface is the mountainous region. The world has one tenth people to live in there and the resources which come from mountainous region support nearly one second population’s life.It is obvious that mountainous region is an important component of the system, which supports the life on earth, and is a foundation, which concerns the survival and development of ecosystem on the earth. But in recent years, the overexploitation of mountainous region has induced a series of eco-environmental problems, and seriously restricted the development of regional economy. Taken soil that is an essential factor of mountainous region environment as the cut-in-point, using geo-informatic tupu and GIS to study the distribution and variety law of mountainous soil vertical zone, will help us to inverse the change of mountainous region environment and forecast its future development trend.Then to offer scientific evidences and decision supports for regional economic and societal sustainable development.Geo-informatic tupu is a new method, which can summarize abstractly and think of figure, large amount of earth information obtained from remote sensing, geodatabase and geographic information system, show space-time change law of the earth system and every key element and phenomenon on every scale, with computer multidimensional visual technologies. And GIS is a technology that is can storage, process, query and analyse the geo-spatial information. Based on these, the research on soil vertical zone has very important meaning for theory and application. With the analysis of geographic cognition and spacial model, it is useful to forming a deeper understanding of vertical zone.On the basis of forefathers’research results, this paper has taken Yunnan province as a research area due to the various physiognomy and typical mountainous characteristics. The study has built the storage structure of soil vertical zone to realize its digital display and discover two spatial distribution laws of soil vertical zone. Then according to the data characteristic of vertical zone, the application range and so on, the study has designed an information system of mountainous soil vertical zone in Yunnan province using Geodatabase, ArcGIS engine and C# to implement dynamicly link between the tupu with geography position. Using the system people can real-time and highly efficient enquiry relevant information. Because of the limitation of author’s level and knowledge, insufficient of time and energy, this study has not researched figure calculation, knowledge discovery and data mining, which is a field need to study further.更多还原
