青海省互助土族自治县粮食安全问题探讨

当前，世界粮价不断上涨，国际金融危机仍在蔓延和加深，粮食安全问题已成了共同关注的话题。本文运用粮食安全理论预测互助县耕地需求量，综合平衡法预测互助县耕地保有量，然后对比分析。互助县未来耕地保有量，近期基本能保证粮食安全，但长远来看，如果考虑到未来发展趋势人口增加、耕地面积减少、气候变化等因素影响，要解决该地区的粮食自给问题仍需要采取科学的保护措施。

公路建设中水土流失分析及对策建议

以天津地区公路建设为例,分析了公路建设过程中水土流失主要受降雨、植被的减少、地形、土壤、人工因素等方面的影响。根据水土流失方程式对公路施工前后水土流失的情况进行了分析,结果显示公路建成一般需要2~3年,由于植被的恢复,水土流失可恢复到施工前的水平,并且随着植被的生长,道路沿线的水土流失会比施工期减轻。

Bauxite and alumina: trends and prospects

During the past 25 years the bauxite and alumina industry has grown threefold creating major change in the industry structure and reducing the dominance of the majors. Australia has emerged as the leading producer with a major third party alumina market developed principally by Alcoa of Australia. Future growth while, less dramatic, is likely to be substantial requiring US$50 billion to fund new projects which will be concentrated in developing countries with large bauxite reserves and developed infrastructure.     

Smart and eco-cities in India and China

ABSTRACT

Smart and eco-cities have become important notions for thinking about urban futures. This article contributes to these ongoing debates about smart and eco-urbanism by focussing on recent urbanisation initiatives in Asia. Our study of India’s Smart Cities Mission launched under the administration of Narendra Modi and China’s All-In-One eco-cities project initiated by Xi Jinpin unfolds in two corresponding narratives. Roy and Ong’s [2011. Worlding Cities: Asian Experiments and the Art of Being Global. Oxford: Wiley-Blackwell] “worlding cities” serves as the theoretical backdrop of our analysis. Based on a careful review of a diverse set of academic literature, policy and other sources we identify five process-dimensions for analysing the respective urban approaches. We show how the specific features of China’s and India’s urban focus, organisation, implementation, governance and embedding manifest both nations’ approaches to smart and eco-urbanism. We argue that India’s Smart City Mission and China’s All-in-One project are firmly anchored in broader agendas of change that are set out to transform the nation and extend into time. The Indian Smart City Mission is part of a broader ambition to transform the nation enabling her “smart incarnation” in modernity. Smart technologies are seen as the key drivers of change. In China the framework of ecological civilisation continues a 5000-year historical tradition of civilisation excellence. By explicitly linking eco-urbanism to the framework, eco-cities become a means to enact ecological civilisation on the (urban) ground.

The planning and management of African river and lake basin development and conservation

The success of river and lake basin development and management is rooted in the knowledge of its resources, both physical and human. Within the framework of an integrated basin plan, each economic sector depends on the adequacy of such data for its individual development. The management and conservation of the basin itself in turn depends on knowing the requirements of those sectors and their probable impact on each other and on the status of the basin's resources, its ecology and environment. The development of African river basin resources is subject to various constraints, some for physical and climatic reasons, others tied to socio-cultural characteristics and the priorities of national economies. These are reflected in financial, manpower and institutional limitations, problems of finding technologies suited to specific local conditions and concern for human health. The scale and complexity of river basin development make it difficult to predict precise outcomes of planned proposals, but a progressive approach which links long-term activities with achievable, shorter term production projects offers prospects for ultimate success.
