During 1993 advertised geography lectureships in British Universities reached unusually high levels, most probably due to major structural changes in tertiary education and the provision of funding attached to research ranking, superimposed on the general trends of increasing student numbers and an ageing academic population. As the research assessment exercise takes place every four years, and the new academic league tables have just been published, it is predicted that a similar surge in advertised lectureships will occur during 1997 and 1978. Research active New Zealand geographers are well placed to capitalise on this projected recruitment phase, which is likely to peak between April and July and again in November. Some specialist subjects within the discipline are in greater demand than others although their popularity may change over time. Many of the traditional obstacles that have in the past discouraged New Zealanders from targetting an academic position in Britain are now more perceived than real. 相似文献

延津县农田投能已达到我国中低产地区的农田投能水平,无机能投入已超过全国平均水平。畜力能投入高是该地区农田投能的特点,有机肥能投入低是该地区农田投能中存在的问题。通过适度规模经营、农田基本建设、精耕细作和合理轮作,可以提高农田投能效率。 相似文献

<正> 一个国家林业的产业属性和社会公益属性的强弱,在较大程度上决定了该国林业科研的机构组成、人员配置和经费来源等系统运行的特征与差异。在市场经济条件下,多数林业发达国家的林业科研运行体系有两大特点,一是具有产业属性的林业科研活动多由公司等市场力量来主导,二是具有社会公益性属性的林业科研活动则主要由政府主导。就政府主导型的公益性林业科研活动而言,发达国家和发展中国家的主要差异表现 相似文献

The temperature distribution at depth is a key variable when assessing the potential of a supercritical geothermal resource as well as a conventional geothermal resource. Data-driven estimation by a machine-learning approach is a promising way to estimate temperature distributions at depth in geothermal fields. In this study, we developed two methodologies—one based on Bayesian estimation and the other on neural networks—to estimate temperature distributions in geothermal fields. These methodologies can be used to supplement existing temperature logs, by estimating temperature distributions in unexplored regions of the subsurface, based on electrical resistivity data, observed geological/mineralogical boundaries, and microseismic observations. We evaluated the accuracy and characteristics of these methodologies using a numerical model of the Kakkonda geothermal field, Japan, where a temperature above 500 °C was observed below a depth of about 3.7 km. When using geological and geophysical knowledge as prior information for the machine learning methods, the results demonstrate that the approaches can provide subsurface temperature estimates that are consistent with the temperature distribution given by the numerical model. Using a numerical model as a benchmark helps to understand the characteristics of the machine learning approaches and may help to identify ways of improving these methods. 相似文献

Approaches to improve the governance of social–ecological systems are difficult to define in situations where governance is weak, that is, involving limited interactions between the actors and weak management of natural resources. This article analyzes an action research process implemented in the Chaouia coastal region of Morocco, where weak governance of the social–ecological system led to a groundwater and agricultural crisis. A dialogue between local actors was set up with the aim of identifying strategies to address the crisis. First separately and then together, farmers’ groups and staff members of public organizations analyzed the existing situation, scenarios for the future of the area, and strategies to cope with the crisis. Contrary to the expectations of the participants, farmers and staff members of public organizations had productive discussions. This approach clarified how social learning can be achieved and governance improved in this situation of weak governance. 相似文献

兰州南北两山生态环境脆弱,自然状态下无法达到城市发展的绿化要求,必须进行生态环境建设。针对生态环境建设的决策困境,提出构建“决策支持系统+专家知识”的决策支持模式。在详细阐述此决策支持模式的基础上,以兰州南北两山作为研究案例,建立了兰州南北两山生态环境建设决策支持系统,通过该系统的试验结果讨论,最终给出兰州南北两山生态环境建设的两项用水措施建议,即: ①在多年平均降雨量大于400 mm的区域进行人工集雨;②在多年平均降雨量小于400 mm的区域进行人工灌溉(灌溉量相当于200 mm降雨)。最后结合专家知识形成兰州南北两山生态环境建设规划图,供决策者参考。 相似文献
