Understanding farmer intentions to connect to a modernised delivery system in an Australian irrigation district: a reasoned action approach

Australian governments have sought to invest in irrigation infrastructure to improve the efficiency of water delivery to rural properties and improve water supply and on-farm efficiency. A programme of rationalising irrigation infrastructure has attracted criticism and doubts about its likely success. Attitude theory in the form of the Reasoned Action Model was applied to understand the intentions of landowners to connect to a ‘modernised’ irrigation system. Attitudes towards connecting to the system, social norms and perceptions of control over the behaviour provided an explanation of intentions to connect. Actual financial capability and other variables were important in discriminating a group of landowners who had already connected to the modernised system from farmers who had not.     

PWM变频驱动电机轴电压与轴电流的测试方法

PWM变频器的广泛应用大大改善了电机调速性能,但是,由于PWM变频器共模电压在电机内部耦合电容作用下,形成轴电压和轴电流,会引起轴承早期失效危及系统安全运行。轴电流问题的研究包括对轴电流的分析、预测和抑制。然而这些过程需要轴电压和轴电流的准确测量进行验证和比对分析。设计合理而有效的测量装置和测量方法是非常重要的一环。在分析轴电流产生机理的基础上,对现有的各种轴电流测量方法和轴承阻抗特性测试方法进行介绍,总结对比这几种方法的优缺点,为轴电流的测试平台的新设计提供参考。     

水资源环境承载能力监测预警平台设计探讨

The social and ecological determinants of common pool resource sustainability

We study a dynamic common pool resource game in which current resource stock depends on resource extraction in the previous period. Our model shows that for a sufficiently high regrowth rate, there is no commons dilemma: the resource will be preserved indefinitely in equilibrium. Lower growth rates lead to depletion. Laboratory tests of the model indicate that favorable ecological characteristics are necessary but insufficient to encourage effective CPR governance. Before the game, we elicit individual willingness to follow a costly rule. Only the presence of enough rule-followers preserves the resource given favorable ecological conditions.

An in-depth view of climate change:addressing climate change while making a transition on the development mode

While fossil fuels greatly contribute to human society,they pose great challenges to natural resources,the environment,and climate change.Developed countries,like the United States,formulated strategic measures to ensure their sustainable development and leading positions in the world.These measures include new green policies,development of shale gas,revitalization of nuclear power,energy independence,reindustrialization,and new low-carbon development based on a combination of Internet technology and renewable energy.Developing countries are also trying to introduce balanced strategies of poverty alleviation and sustainable development.Globally,industrial civilization is being transformed to ecological civilization and green,low-carbon development is a global trend.Addressing climate change provides new strategic factors to further this development.China should take substantial actions to realize sustainable development in a new road:China is in the critical stage of changing its development mode,so it is vital to choose an appropriate development path.This extensive development comes at the high price of consuming too much resources and scarring the environment.Mitigation and adaptation strategies for addressing climate change can help the transition of development.Based on the analysis of the development data of developed countries,the author introduces the concept of"two-type developed countries"with an understanding that not all developed countries must take the same development mode.He also holds the view that China should achieve modernization in a more energy-saving and more carbon-efficient manner compared with that of two-type developed countries.An analysis of"two competitions"that China is facing shows that changing the developing mode is urgent and China should grasp this opportunity in the next five to ten years,which is a key period for this transition.This paper discusses the low-carbon development goals and the three-step process.Low-carbon development does not necessarily restrict economic development.It,however,can expedite the transition of the development mode and this is a low-carbon and green development path.Transition of the development mode includes implementation of China’s green and low-carbon energy strategies,low-carbon society construction,development of agriculture and forestry,garbage sorting and utilization,innovation of urbanization,etc.Improvement of national infrastructure construction includes water safety,environment and climate monitoring system,intelligent energy web,basic database,etc.Addressing climate change can significantly improve the nation’s basic research level.In summary,it mitigates backward production capability,extensive development,and environmental damage while promoting technological advancement,scientific development,and ecological civilization.     

江汉平原土地资源诅咒效应研究

将资源诅咒的研究领域由传统的矿产资源转向土地资源研究问题域,以近10a江汉平原18个县(市)的统计数据为依据,运用诅咒系数对其进行资源诅咒的实证分析。结果显示,近年来发展滞后的荆州市所辖的监利县、江陵县以及其他7个县市的土地资源诅咒系数大于1,确实存在资源诅咒现象,且江陵县与监利县还属于严重诅咒区。通过对选取指标作进一步的计算分析,得出导致其产生资源诅咒的原因主要为:以土地资源为依托的农业没有得到高效发展,而受到发展观念与投入等束缚,其二、三产业发展同样滞后。根据影响资源诅咒地区产业发展的具体因素,有针对性地给出化解土地资源诅咒的对策建议,为今后资源诅咒地区打破诅咒束缚,持续快速发展指明方向。
