In a globally warming world, subtropical regions are generally expected to become drier while the tropics and mid-high latitudes become wetter. In line with this, Southwest China, close to 25°N, is expected to become increasingly prone to drought if annual mean precipitation decreases. However, despite this trend, changes in the temporal distribution of moisture supply might actually result in increased extreme rainfall in the region, whose climate is characterized by distinct dry and wet seasons. Using hourly and daily gauge observations, rainfall intensity changes since 1971 are exalnined for a network of 142 locations in the region. From the analysis, dry season changes are negligible but wet season changes exhibit a significantly strong downward trend [-2.4% （10 yr）^-1], particularly during the past 15 years [-17.7% （10 yr）^-1]. However, the intensity of events during the wettest of 5% hours appears to steadily increase during the whole period [1.4% （10 yr）^-1], tying in with government statistical reports of recent droughts and flooding. If the opposing trends are a consequence of a warming climate, it is reasonable to expect the contradictory trend to continue with an enhanced risk of flash flooding in coming decades in the region concerned.

为了探究土地集约利用与城镇化的耦合协调关系,促进两者协调发展,以安徽省为例,首先,运用熵权TOPSIS模型,分别评价安徽省2000—2017年土地集约利用与城镇化绩效水平,研判两者的绩效水平及其子系统变化趋势;然后,运用耦合度和协调度模型,基于耦合作用系数的取值变化,探讨不同情形下安徽省土地集约利用与城镇化协调发展关系及变化趋势;最后,运用障碍度模型,诊断影响安徽省土地集约利用与城镇化协调发展的障碍因子。结果表明:2000—2017年,安徽省土地集约利用与城镇化水平均呈逐年上升态势,稳中趋好。2000—2017年安徽省土地集约利用绩效水平从0.0536增至0.9587,年均增长18.49%;安徽省城镇化水平从0.2715增至0.8180,年均增长6.70%。从土地集约利用各子系统来看,经济绩效子系统对土地集约利用的贡献最大,生态绩效子系统对土地集约利用的贡献最小,权重分别为0.3526和0.1308;从城镇化各子系统来看,经济城镇化子系统对城镇化水平影响最大,生态城镇化子系统对城镇化水平影响最小,权重分别为0.4160和0.1377。在不同耦合作用系数取值情形下,安徽省土地集约利用与城镇化协调发展关系变化趋势除2005年和2012年略有不同外,其余16年两者协调发展变化趋势和协调类型完全相同,说明耦合作用系数对两者协调发展关系的影响十分有限。2000—2017年安徽省土地集约利用与城镇化的协调发展度呈逐年增长态势。从各子系统障碍度来看,土地集约利用经济子系统对安徽省土地集约利用与城镇化协调发展的影响最大,年均障碍度为16.48%;生态城镇化子系统对两者协调发展的影响最小,年均障碍度为6.60%。从各指标障碍度来看,2011年及以前,影响两者协调发展的障碍因子主要包括人民生活水平、地均财政收入和人均GDP;2012年及以后,影响两者协调发展的障碍因子主要包括城乡人均可支配收入差距和城镇人口密度。从各年份前5位障碍因子变化来看,各指标对土地集约利用与城镇化协调发展的影响可以分为2个阶段:第1阶段(2000—2013年)以土地集约利用的影响为主,第2阶段(2014—2017年)以城镇化的影响为主。本研究为研判土地集约利用与城镇化协调发展水平及诊断障碍因子提供了新的思路和方法,可为促进安徽省及同类省域土地集约利用与城镇化协调发展提供借鉴。

定量评估土地利用绩效并诊断其障碍因子,是提高区域土地利用绩效水平的有效途径。该文综合考虑土地利用经济绩效、社会绩效、生态绩效和管理绩效4个子系统,建立区域土地利用绩效评价指标体系,结合熵权TOPSIS模型和障碍度模型,对安徽省近15 a(2000—2014年)的土地利用情况进行绩效评价和障碍因子诊断,并基于评价结果,运用GM(1,1)模型对安徽省未来5 a(2015—2019年)土地利用子系统绩效变化态势进行预测和分析。结果表明:安徽省土地利用综合绩效经历了较差—中级—良好—优质的发展过程,结合土地利用绩效的年均增长速度,可以分为绩效较差但高速增长(2000—2004年)、绩效中级但较快增长(2005—2009年)、绩效良好但低速增长(2010—2011年)和绩效优质且快速增长(2008—2014年)4个发展阶段。4个子系统绩效水平基本逐年提升,但变化趋势存在差异,经济绩效和管理绩效呈线性增长态势,社会绩效和生态绩效呈波动起伏变化的上升趋势;未来5 a,经济绩效子系统年均增长速度最快,社会绩效和管理绩效子系统次之,生态绩效子系统增速最慢。经济绩效子系统障碍度最大,其后依次是社会、生态和管理绩效子系统;2000—2008年,建成区工业增加值等3个指标一直稳居前3位,人民生活水平和地均就业人数轮流出现在第4或第5位;2009—2012年,前3位障碍因子发生较大变化,地均财政收入和人民生活水平成为阻碍土地利用绩效的主要因子;2013—2014年,前5位障碍因子变化较大,社会绩效成为制约土地利用绩效的主要子系统,改善人民生活水平、加强公共基础设施建设,探索节约化、集约化、高效化的土地利用方式和模式是提升安徽省土地利用绩效的重要出路;根据GM(1,1)模型预测结果,社会绩效、生态绩效和管理绩效在未来具有广阔的提升空间,安徽省在提高土地利用经济绩效的同时,应关注经济—社会—生态环境友好和谐发展,更加注重土地利用社会绩效、管理绩效特别是生态绩效的提升。该文的研究思路与方法可以为促进区域土地利用绩效提升提供现实依据。

作者： robin Batterham Kernot Professor of Engineering the University of Melbourne

The article by Jinghai Li in this issue of Engineering[1] calls for a new approach to how we organize science and technology （S＆T）, given that we are encountering more challenges than solutions. His paper is a plea and a demand for more transdisciplinary ap- proaches to solving real-world, complex challenges, in the light of the reductionist approach that results in disciplines splintering into ever tighter groupings. His own approach of using mesoscale considerations to link the microscale and macroscale has been demonstrably successful over many years.

Glass fi ber reinforced gypsum(GFRG) wall panels are prefabricated panels with hollow cores, originally developed in Australia and subsequently adopted by India and China for use in buildings. This paper discusses identifi cation and calibration of a suitable hysteretic model for GFRG wall panels fi lled with reinforced concrete. As considerable pinching was observed in the experimental results, a suitable hysteretic model with pinched hysteretic rule is used to conduct a series of quasi-static as inelastic hysteretic response analyses of GFRG panels with two different widths. The calibration of the pinching model parameters was carried out to approximately match the simulated and experimental responses up to 80% of the peak load in the post peak region. Interestingly, the same values of various parameters(energy dissipation and pinching related parameters) were obtained for all fi ve test specimens.
