《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员
气候变化、饮水短缺、耕地沙漠化、贫富差距、恐怖主义……这些都似乎已经是老生常谈了,然而问题的关键在于,我们应当知道事情的严重性已经到了什么程度。在《全球脑的量子跃迁:新科学如何能够改变我们及我们的世界》中,拉兹洛为我们勾勒了一幅全新的“实在地图”,并罗列了个人以及集体所面临的各种问题、机遇和挑战、旨在帮助理解在此巨大的过渡期我们应当做些什么。社会结构正在遭受破坏,气候不断恶化,海平面上升,自然灾害频发,人类社会来到了一个大瓦解或大跃迁的临界点,要么立即行动,走向一个更和平、更生生不息的世界,要么“照常营业”,全球崩溃瓦解,无一幸免……
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
