论四川产业结构调整的影响因素

四川作为一个农业大省目前正面临着产业结构调整的机遇和挑战。本文结合影响经济增长的三大因素即劳动力、资本以及技术进步来分析对四川产业结构的调整,并提出若干发展思路和意见。

山地城市绿道规划策略探讨

山地城市的地貌特征、生态格局、交通结构等方面与平原城市有较大差异,对绿道规划理论与方法提出了不同需求。以泸州市中心城区绿道规划为例,基于其山水风貌、慢行交通需求以及人文景观特色等要素,探讨了山地城市的绿道规划策略。将泸州中心城区绿道划分为城市级、片区级、社区级进行建设,优化生态格局,凸显山水风貌。通过优化快慢交通接驳、完善公共自行车运营系统,引导居民绿色出行。串联自然景观与人文景观,展现地域性历史文化特色。运用网络与信息技术,实现绿道的智慧管理、智慧服务与智慧体验,构筑智慧城市新生态。

园林设计中的理水手法浅析——以安庆菱湖公园为例

水体作为可塑性极高的园林要素之一,在中国古典园林设计中扮演重要角色。安庆菱湖公园作为安徽省建成最早的园林式公园,水面占总面积比例超过45%。本文以菱湖公园为研究对象,分析园林设计中的主要理水手法。分析结果表明,菱湖公园的水体布局合理有序,空间层次分明。菱湖公园结合自然水域的结构特点,通过对多种水体形态特征与滨水景观的合理应用,较好地实现水体、环境、人文三者统一的园林设计理念。

亚洲金融危机国家十年来的金融发展

作者在对亚洲金融危机进行简要回顾的基础上,系统地总结了危机之后主要国家的金融改革与发展以及危机之后的亚洲金融合作。经历了危机的主要国家在危机之后都普遍地进一步放松了对金融的管制,推进了金融领域的经济民主化进程,实施了金融稳定化措施,但监管得到了强化。研究发现,危机之后,各国放弃了反资本全球化的民族主义情绪,反而将对国外资本的开放视为促进国内金融稳定的一个重要举措。同时,亚洲地区也在试图改变地缘经济与政治结构,加强金融合作,提高亚洲地区应对各种外部冲击的灵活性和自主性。

自然低温下红茴香和双蕊野扇花的耐寒性研究

以红茴香(Illicium henryi Diels)和双蕊野扇花(Sarcococca hookeriana var.digyna Franch)为试验材料,在越冬期间持续观察叶片的形态变化,并测定植株叶片的叶绿素含量、相对电导率、可溶性糖含量等生理指标,为2种植物在北方地区园林的引种栽培应用提供依据。结果表明:红茴香和双蕊野扇花在寒冷环境下仍能保持较好的生长状态,表现出较强的耐寒能力;在越冬过程中,红茴香和双蕊野扇花叶片的相对电导率、过氧化物酶活性均呈现出先升后降的变化趋势,可溶性蛋白含量则呈现出先降低后升高的变化趋势,可溶性糖含量随温度下降而升高,各指标与气温之间的相关性也较大。综上,红茴香和双蕊野扇花对引种地的低温环境均表现出了一定适应能力,能及时运行体内各种调节机制抵御低温伤害。

Elements and Element Components of the Rural Landscape in Linpan of Western Sichuan in Relation to Perception,Preference and Stress Recovery

Natural environments contribute to people’s perception,preference and health restoration.Many researchers have focused either on the positive effects of overall rural environments on stress recovery or concentrated on the perception and preference aspects of the rural landscape,but few have integrated perception,preference and stress recovery simultaneously.This paper developed a framework which includes 11 elements and 38 element components related to Linpan,China,and distributed it online as part of a survey.As a result,a total of 324 valid questionnaires were collected.The questionnaire included demographic details,perception and preference degree for Linpan,as well as self-estimations of stress recovery.Stepwise multiple linear regression was employed,and revealed 16 significant predictors for the perception,preference and stress recovery in rural environments.In terms of elements,atmosphere and imagery were the two elements that could be best perceived,while woodland,farmland,water,residence and road were the five most important elements for the preference.Moreover,seven elements were also identified as significant predictors for stress recovery.Among the element components,tranquility as well as road and water proximity were the two significant predictors for perception,while wide visibility as well as woodland and residence blending contributed significantly to stress recovery.The five element components of woodland interior,vegetable field,stream,courtyard space and branch road each had a significantly predictive ability for preference and stress recovery.These findings extend the understanding of the perception,preference and restorative properties of rural environments through the combination of elements and element components in Linpan of Western Sichuan,helping to improve the quality and characteristics of rural external and internal environments and create health-promoting environments.
