《区域地理学原理》以系统科学理论为指导，从区域系统的组成要素、功能类型、结构变化、矛盾冲突、空间关联、战略规划、研究方法等方面，深入探索区域系统的运行规律和区域地理研究内容，提炼总结出区域地理的五大基本原理，即人地关系原理、地域分异原理、效用*大化原理、尺度一规模原理以及复杂性与自相似性原理．这些原理既是区域地理学的基本原理，也是地理学、经济学和系统科学基本规律在区域层面交叉融合的表现。《区域地理学原理》还对区域的共性与个性、区域界线的客观性与主观性、区域发展目标的人本性与发展过程的可持续性，以及区域经济一体化与世界经济一体化的矛盾冲突等前沿问题作出思考。 《区域地理学原理》适合于地理学、应用经济学、公共管理学等学科的师生使用，也可供发展改革、国土管理和区域规划领域的从业人
An introductory text and reference on mining engineeringhighlighting the latest in mining technology Introductory Mining Engineering outlines the role of the miningengineer throughout the life of a mine, including prospecting forthe deposit, determining the site's value, developing the mine,extracting the mineral values, and reclaiming the land afterward.This Second Edition is written with a focus onsustainability-managing land to meet the economic and environmentalneeds of the present while enhancing its ability to also meet theneeds of future generations. Coverage includes aboveground andunderground methods of mining for a wide range of substances,including metals, nonmetals, and fuels. Completely up to date, this book presents the latest information onsuch technologies as remote sensing, GPS, geophysical surveying,and mineral deposit evaluation, as well as continuous integratedmining operations and autonomous trucks. Also included is newinformation on landscape restoration, regional planning, wetlandspr
