In fact, Computer Graphics indicate the developmental level of the Computer software and hardware, This is because Graphics have become the most important medium to transfer all kinds of information. Computer Graphics?research object is graphics, and the point , line and surface make up of the graphics ,In addition, During the real application, every graphics is made up of millions of the lines and curves, the speed and quality of the line and curve affected the implement of the whole graphics.
计算机图形学的研究对象是图形,而构成图形的几何要素就是刻画形状的点、线、面、体等,并且在具体应用中,每一幅图形都由成百上千条直线和曲线构成,这样对于每一条直线或曲线的处理速度和质量极大地影响着整幅图形的处理速度和质量,因此,对于计算机图形学基础算法的研究就具有重要意义,本文就是对计算机图形学的基础算法进行研究,包括直线和曲线的生成和裁剪算法以及基本象素的图形变换。

Taking Changling County, Zhenlai County and Da'an City of Jilin Province as researchareas, based on remote sensing data, graphics operation and spatial analysis are carried out indifferent points of views, including temporal, spatial, scale and landscapeetc; all aspects analysis of this dissertation are abstractively expressed by digital graphics andseries of curves which are not stick to one pattern to discussing multi-dimension andcomplicated attributes of the salinized process. Linking up temporal-spatial characteristicswith landscape indices while combining mathematics model and Geo-informatic TUPUmodel, this dissertation puts forward the fundamental frame: temporal-spatial evolvementpattern, spatial extension process analysis and landscape characteristics analysis of salinizedland. Temporal-spatial evolvement pattern analysis extracts the essential quantity features andtransformation modes of salinized land, and also analyzes patches spatial geometricalparameters scale feature; spatial extending process analysis discusses the change rate andecological modes; landscape feature analysis utilizes landscape graphics indices to describesalinized land microcosmic graphics features and changes.
信息图谱模型为土地盐碱化研究提供了一种谱系化、定量化与定位化相结合的研究方法,本文选取吉林省西部盐碱化典型区域长岭县、镇赉县、大安市作为研究区,以遥感影像为基础数据,在GIS技术支持下,从时空变化、尺度效应、景观特征等多个角度对盐碱化土地进行图形运算、空间分析,通过不拘一格的数字化图形、曲线系列抽象表达出不同维度上的特征与规律,探讨土地盐碱化过程的多维性与复杂性,将盐碱化土地时空特征与景观特征衔接、数学模型与图谱模型结合,以盐碱化土地时空演变基本模式、空间扩展过程和景观特征分析为框架构建盐碱化土地信息图谱模型研究体系,发挥图谱模型数据挖掘、知识发现的特长,将宏观动态变化与微观特征相联系,进一步挖掘土地盐碱化过程与人类活动影响的关系,为探索研究区盐碱化土地成因、过程,预测其未来发展变化趋势及其对环境影响提供相关科学依据。
