课程名称:在 ArcGIS 中利用层次分析法(AHP)绘制沙漠中的地下水区域 课程概述:本课程是一个实用且易于学习和应用的指南,旨在帮助学生使用地理信息系统(GIS)工具和层次分析法(AHP)勘测沙漠地区的地下水区域。课程中的知识和技能易于掌握,适用于学生所选择的任何研究区域。尽管有些人可能会感到惊讶,沙漠区域下方其实也蕴藏着地下水。地下水通常在地表下缓慢流动,但在某些地方,它会在泉水处涌出。地下水是地球上液态淡水的最大储藏,存在于含水层、孔隙岩石和沉积物中,水分被土壤颗粒吸引并通过毛细作用移动。层次分析法(AHP)是最广泛应用的多标准决策分析工具,常用于GIS分析中的多个目的,包括土壤侵蚀建模。AHP结合了心理学和数学方法,为不同选择分配适当的权重,无论是在选择大学专业、购买汽车还是寻找伴侣时。课程中将运用AHP为六个直接影响地下水形成的主题层分配权重。这些权重将考虑地方气候、土地坡度、岩石和土壤类型、植被覆盖、土地利用、水分保留和线性地带等因素。本课程将教学生为任何研究区域准备相关的主题层。完成本课程后,学生将能够为任何属于干旱和半干旱地区的研究区域创建地下水区域图。这些成果可以用于论文写作或文章发表,也可用于开展研究项目。
This course is a handful, easy to learn, and apply guide for students, who want to apply GIS instrument and Analytical Hierarchy Process (AHP) to delineate groundwater areas in desert zones. The knowledge and skills represented throughout the course are easy to master and apply for any study area a student desires. Although this might seem surprising, desert areas also have groundwater beneath. Usually, groundwater travels slowly and silently beneath the surface, but in some locations, it bubbles to the surface at springs. Groundwater is the largest reservoir of liquid fresh water on Earth and is found in aquifers, porous rock and sediment with water in between. Water is attracted to the soil particles and capillary action, which describes how water moves through a porous media, moves water from wet soil to dry areas.AHP is the most widely applied multi-criteria decision analysis tool and is used for multiple purposes during GIS analysis, including soil erosion modelling. AHP incorporates both psychological and mathematical methods to assign appropriate weights while making a different choice, whether it is choosing a university department, buying a car, or even searching for a partner. In this course, AHP will be used to assign weights for six thematic layers that directly influence to formation of groundwater. The amount of water that is available to enter groundwater in a region is influenced by the local climate, the slope of the land, the type of rock and soil, the vegetation cover, land use in the area, water retention and lineaments areas.The course will teach to prepare all those thematic layers for any study area. By accomplishing this course a student will be able to create a map of groundwater areas for any study area that belongs to arid and semi-arid regions. The results a student may use either for thesis dissertation or publication of an article, as well as conducting a research project.
