试论人为矿床开发利用     

刘家仁 《贵州地质》2006,23(2):142-146

本文介绍了人为矿床的概念和研究概况,论述了人为矿床的分类、特征及开发利用的意义、优势、工作重点和难点。文章指出:人为矿床就是人类活动所产生的可以进行规模化利用而现在仍被视为“废弃物”的各种物质;人为矿床大多具有污染源和资源的双重属性,开发利用人为矿床是治理环境污染的釜底抽薪之法,开发利用人为矿床可以收到经济和环保的双重效益;人为矿床具有活动性和增生性,是真正“取之不尽用之不竭”的矿床,开发利用人为矿床,是发展循环经济的重要途径;人为矿床的分布与人类活动区域相关、赋存状态迥异于自然矿床、物质成分十分复杂;人为矿床具有可人为控制的特性;开发利用人为矿床,需要进行广泛的社会动员。  相似文献   

Blue grabbing: Reviewing marine conservation in Redang Island Marine Park,Malaysia     

《Geoforum》2017

While academic literature and media attention has rightly focused on the numerous instances of land grabbing taking place in various corners of the world, far less attention is paid to the enclosure, appropriation and dispossession taking place in the guise of marine conservation – or the recently developed concept of “blue grabbing”. Blue grabbing articulates how marine conservation results in the appropriation of marine resources and coastal land from previous custodians by more powerful actors, such as state and tourist operators. Blue grabbing can be considered a form of primitive accumulation, yet dispossession via marine conservation does not take the conventional form of privatising land, as the spaces involved are still formally state-owned areas. Rather, it is the benefits from natural resources that contribute to capital accumulation of tourist operators and indirectly the state. Restrictions on local resource use are justified using degradation narratives of “overfishing”, while financial benefits from tourism are drained from local communities within a system lacking transparency. This intervention draws on fieldwork research to reveal how blue grabbing plays out in Redang Island Marine Park, Malaysia, yet given that blue grabbing is a recently developed concept, argues there is a pressing need for research to build a more informed picture.  相似文献   

The changing framework of shipping: Trends in trade,technology, and policies     

Hans Böhme 《Marine Policy》1984,8(3):229-238

The author analyses prospects and policy options for shipping in the context of three major influences: changes in seaborne trade; technical and organizational innovation; and changes in the political environment of shipping. Finally, he stresses the urgency of the need to remove the tonnage surplus — an essential feature of any restoration of equilibrium between supply and demand.  相似文献

HUMAN RELATIONS AND PRIMARY HEALTH CARE DELIVERY IN RURAL NEPAL: THE CASE OF DEURALI *     

Nanda R. Shrestha 《The Professional geographer》1988,40(2):202-214

A preliminary analysis of the primary health care delivery component of a small rural development project in Deurali, Nepal, suggests that personal relations between project personnel and their target population (e.g., implementors'sincerity and commitment to service) can overcome many cultural, geographical, and class-related social barriers to achieving project objectives. The Deurali medical staff's ability to combine their technical skills with sincerity, hard work, and commitment has made the Deurali project reasonably successful in meeting villagers'primary health care needs.  相似文献
