广州近代城市公园的中西合璧特征探析     

唐孝祥  余文博 《广东园林》2020,42(1):70-74

广州近代城市公园设计精巧,风格独特,在岭南造园史上具有重要地位。结合历史图文资料,运用风景园林史学和风景园林美学相结合的研究方法,归纳分析其造园特征。广州近代城市公园的中西合璧特征主要体现在3个方面:因地制宜的空间布局、中西融合的建筑小品、多姿多彩的植物景观。探析其中西合璧特征,有利于丰富岭南近代园林历史与理论研究,推进对广州近代城市公园的保护与造园智慧的传承。  相似文献   

“花间隐榭，水际安亭”——基于华南植物园水榭和桂林芦笛岩水榭的营境分析     

翁子添 《广东园林》2020,42(1):31-35

华南植物园水榭和桂林芦笛岩水榭是20世纪七八十年代岭南园林建筑的两处经典作品。它们与明代造园专著《园冶》里"花间隐榭,水际安亭"的字句遥相呼应,以现代主义建筑的创作风格构造出中国传统山水居游的惬意情境。以这两个经典现代风景建筑为例,尝试从情境、场景和身体体验3个不同角度,具体探讨风景建筑的营境操作。情境旨在针对建筑总体布局进行分析;场景则着眼于空间组合的探讨;最后从身体体验出发,讨论建筑的细部设计。  相似文献

不同品种青贮玉米群体光合性能指标的变化     

张瑞霞  刘景辉  陈友君  朱树国  云丽娜  闫睿卿 《中国农学通报》2007,23(1):208-208

通过对不同青贮玉米品种群体光合性能指标的研究结果表明，不同青贮玉米品种叶面积指数、光合势、群体生长率在整个生育期均呈单峰曲线变化，峰值出现在散粉至乳熟期间，因不同品种而异。净同化率则呈“马鞍”型曲线变化。多分蘖品种科试1号、植株高大品种东陵白与农大647在生育期间叶面积指数和光合势均较高，东陵白生育前、中期群体生长率显著高于其它品种，且高值持续时间较长，这是其生物产量高的生理基础。生产中，采取合理栽培措施，克服此类品种植株高大、个体繁茂、群体郁蔽导致植株病害和倒伏严重的不足，可实现青贮玉米群体生物产量的进一步提高。  相似文献   

An economist's perspective on irrigation performance assessment: With examples from large scale irrigation in Morocco     

Laurence E. D. Smith 《Irrigation and Drainage Systems》1990,4(4):329-343

This paper accepts that assessing the performance of irrigated agriculture is difficult because being multi-dimensional it requires a multi-disciplinary approach. Public irrigation schemes may have a number of often competing objectives and are assessed by interest groups with differing values and perspectives. A wide range of performance indicators are thus required. Some of these and the complex inter-relationships that may exist in the system are illustrated.  相似文献   

A review of irrigation performance assessment in California     

D. R. Purkey  W. W. Wallender 《Irrigation and Drainage Systems》1994,8(4):233-249

A survey of irrigation performance assessment as conducted in California was performed. Emphasis was placed on the actual procedures employed by the State's major water providers and irrigation districts. Survey results covered the development of innovative irrigation performance assessment parameters as well as the methodologies used to evaluate these parameters. All aspects of California's irrigation infrastructure were considered, from the management of major hydraulic structures, through water delivery, and on-farm consideration. Environmental performance assessment methodologies were also examined.  相似文献   

Farmer's perspective on irrigation performance     

Mark Svendsen  Leslie E. Small 《Irrigation and Drainage Systems》1990,4(4):385-402

Of the many client groups with interests in irrigation system performance, farmers are probably the least often considered. This paper attempts to explore the meaning of irrigation performance from their perspective, highlighting at the outset basic difference between this perspective and that of system managers. It then reviews several important concepts underlying a consideration of performance in irrigation systems. The paper then proposes and discusses a set of twelve measures of irrigation service judged to be of interest to farmers. These are adequacy, timeliness, equity, tractability, convenience, predictability, temperature, sediment content, salt content, nutrient content, toxics, and pathogens.  相似文献
