基于低碳经济视角的中国能源结构灰色关联度分析

中国正处于经济高速发展的进程中,经济的可持续发展要求中国走低碳发展的道路,要改变以往的高消耗、高排放的经济发展模式.文章通过对中国近9年来的能源生产结构进行了灰色关联度分析,发现原煤、原油、天然气、新能源与总能源的关联度分别为0.873 5、0.608 3、0.725 1、0.762 9.结果表明,中国经济的发展是以消耗原煤为主要能源手段,这种能源结构不利于建构低碳经济.为了实现国民经济的可持续发展,建设"两型社会",必须大力调整产业、能源结构,提高能源的使用效率.

Climate change impacts on rain-fed and irrigated rice yield in Malawi

There is extensive scientific evidence on climate impacts and adaptation in rice (Oryza sativa L.), but the majority relates to production in South Asia and China. Only a handful of studies have been conducted in Sub-Saharan Africa and none in Malawi. In this paper, the climate impacts on rain-fed and irrigated rice yield have been assessed by combining the downscaled outputs from an ensemble of general circulation models (GCM) (HADCM3, INCM3 and IPCM4) with data from the LARS-WG weather generator to drive the CERES-Rice crop model. This was calibrated and validated using 10 years (2001–2010) field data from three rice schemes to simulate the baseline (1961–1990) yield (t?ha^?1) and then model future yield changes for selected (B1 and A2) emissions’ scenarios for the 2050s. Although relatively small increases in average yield were projected (+8% and +5% for rain-fed and irrigated rice, respectively), there was large uncertainty (?10% to +20% yield change) when considering different GCMs and emission scenario. Farmer responses to cope with the projected impacts include both autonomous and planned adaptation strategies, such as modifying planting dates to maximize crop growth calendars and available soil moisture, increased use of on-farm water conservation measures and land levelling to improve water efficiency in rice schemes dependent on surface irrigation.     

中国天气指数保险试点的运行及其评估——以安徽省水稻干旱和高温热害指数保险为例

本文从运行层面评估了中国安徽天气指数保险试点计划.研究发现,中国指数保险试点在运行层面积累了丰富的经验,也面临不少的挑战.为了提高指数保险试点的运行效果,需要加强政府的支持力度、为指数保险寻找已有的发展平台、提高保险意识与促进销售、建立严格的法律和监管体系以及发挥农户这一重要主体的积极性,建立其参与农业保险制度决策与管...     

The effects of macroeconomic and weather conditions on the business cycle of Taiwan’s adventure tourism

This paper utilises a Markov regime-switching model to explore the influences of macroeconomic and weather conditions on the business cycle of Taiwan’s adventure tourism, that is, white-water rafting. The number of rafting participants is used to identify two stages of the business cycle of the white-water rafting industry: the peak and the trough. Our empirical evidence reveals that unemployment has a negative effect on the number of rafting participants in the troughs while it has a positive effect on the number of rafting participants in the peaks. It follows that economic recession would adversely affect the number of participants in adventure tourism in the troughs, while it is not true in the peaks. Moreover, we show that the more the sunshine hours, the more participants travel on white-water rafting in the peaks. However, temperature is not a determinant of demand for adventure tourism under a subtropical climate, which contradicts much of literature.
