国内外旅游地地方依恋研究综述     

吴丽敏  黄震方  王坤  张郴 《热带地理》2015,35(2):275-283

通过对国内外旅游地地方依恋文献资料的梳理,发现研究主要集中在对旅游地地方依恋的概念界定、影响因素、形成机制及影响效应等方面;在方法上,定量研究明显多于定性研究;其理论体系、影响机理及应用领域仍有待深入探讨。国外对旅游地地方依恋研究比国内起步早,主题更为丰富,且在时间与空间尺度均有涉及;今后国内相关研究应注重对旅游地地方依恋的理论体系构建、影响机理剖析及深入挖掘应用领域等方面的探讨,同时还应考虑旅游地的独特性和典型性,兼顾时空尺度对研究可能产生的影响,综合运用定性和定量方法,结合具有中国不同地域文化特质的各类对象,以体现旅游地地方依恋研究的时代性、历史性及动态性。  相似文献   

西方国家社区依恋研究     

常江  谢涤湘  黄健文 《热带地理》2015,35(4):507-514

文章对西方国家的“社区依恋”研究进行了回顾总结,首先将社区依恋和地方依恋2个概念进行了对比,之后分为线性发展模型、系统模型和多因素模型等3个发展阶段介绍了社区依恋的研究阶段,并总结了社区依恋的研究方法和影响因素。研究方法主要有以深度访谈、话语分析和图形法等为主的质性研究方法和以问卷调查、测量量表和统计分析为主的量性研究方法,亦有将两者相结合的综合研究方法;影响因素则主要集中在3个方面：人口统计学因素、社会因素和物质环境因素。最后指出,中国的社区依恋研究应充分考虑中国国情,探索适合自身的理论与方法,综合质性与量性研究方法,针对中国丰富多样的社区类型和具有中国特色的影响因素展开研究,为中国相关政策的制定提供依据。  相似文献   

氧含量及附着面积对海洋底栖硅藻生长和胞外多聚物的影响          下载免费PDF全文

陈琪  武福源  郑纪勇  杨靖亚  蔺存国 《海洋学研究》2017,35(1):66-72

胞外多聚物(extracellular polymeric substance, EPS)是海洋底栖硅藻在水下表面附着时分泌的物质,环境因素对胞外多聚物的组成和分泌行为有直接影响,本文重点探讨了氧含量和附着面积对胞外多聚物的影响。采用热溶剂浸提法提取硅藻胞外多聚物,利用苯酚-硫酸法定量其中的多糖成分,利用考马斯亮蓝G-250法定量蛋白质成分,通过血球计数板法和紫外分光光度法计算细胞数量。结果表明,在氧含量高、可附着面积大的条件下,硅藻的生长繁殖速率快,且单个细胞的胞外多聚物分泌量大。氧含量对胞外多聚物主要成分中的水溶性多糖含量影响大,而对其余成分含量影响小。可附着面积对硅藻附着和生长的影响比氧含量影响小。  相似文献   

Place invaders: Identity,place attachment and possum control in the South Island West Coast of New Zealand          下载免费PDF全文

Susan Bidwell  Lee Thompson 《New Zealand geographer》2015,71(2):81-90

The pesticide 1080 (sodium fluoroacetate) is used in New Zealand as the primary means of controlling the Australian brushtail possum, a problem pest. This study identified place and its role in identity as an important mediator of the perspectives of those that either strongly supported or opposed its use. Individuals' differing constructions of place influenced the way they perceived ‘others’ as a threat to their place and their views on control of its management and protection. This study may contribute to a new understanding of the importance of place in this and other similar natural resource disputes.  相似文献   

温度、光照强度和盐度对海柏果孢子放散与附着的影响     

邓璐  曹翠翠  王宏伟 《海洋科学》2015,39(8):24-27

在实验室条件下,研究了不同温度、光照强度和盐度对海柏(Polyopes polyideoides)果孢子的放散及附着的影响。结果表明:温度10~26℃的条件下,海柏果孢子均能够完成放散附着;18℃时,海柏果孢子放散附着速度最快且总量最大,而当温度低于5℃或者高于30℃时,海柏果孢子的放散附着受到抑制,几乎不放散附着;海柏果孢子放散附着的适宜光照条件为80?mol/(m2·s),光照强度过高时海柏果孢子的放散附着明显受到抑制;盐度为22~36之间利于果孢子的放散附着,当盐度低于8,高于40的时候,海柏果孢子由于受到了盐胁迫,几乎不放散及附着。  相似文献   

海洋细菌在生物表面和非生物表面附着的研究   总被引：2，自引：1，他引：2  

纪伟尚  许兵  徐怀恕  R.R.Colwell 《中国海洋大学学报(自然科学版)》1991,(2)

应用吖啶橙染色荧光显微镜检结合扫描电镜观察研究了海洋细菌在多种生物和非生物表面附着的情况。细菌的附着过程是端生鞭毛首先附着,随后菌体横卧在表面上,然后生长出侧生鞭毛或粘多糖的纤丝,使菌体牢固地附着。硅藻表面没有细菌附着,细菌只附着在硅藻个体之间的间隙内;多管藻及石莼表面有大量细菌附着,多管藻表面还有大量硅藻附着。死贝壳表面有大量球菌、杆菌、丝状细菌及硅藻附着。挠足类动物表面的附着细菌主要是弧菌。  相似文献   

求新动机对游客重游意愿的调节作用研究——以西塘古镇为例     

寿东奇  姜洪涛  章锦河  周佳梅  喻皓  丁风芹 《地理科学》2017,37(1):130-137

以西塘古镇为案例地,利用问卷调查所获取的数据,通过层次回归分析的方法,探讨了重游意愿的形成机制以及不同求新动机水平下旅游者重游意愿的差异。结果表明： ① 满意度和地方依恋对短期、中期和长期重游意愿均有显著影响,求新动机仅对长期重游意愿有显著影响,而目的地形象对重游意愿的影响未达显著水平。② 求新动机对目的地形象与短期、中期和长期重游意愿的关系存在正向调节作用,不同求新动机水平下,目的地形象对重游意愿的影响程度不同。即随着求新动机增强,目的地形象对重游意愿的作用得到加强。③ 求新动机对满意度与短期、中期和长期重游意愿的关系存在负向调节作用,不同求新动机水平下,满意度对重游意愿的影响程度不同。即随着求新动机增强,满意度对重游意愿的作用削弱。④ 求新动机对地方依恋与重游意愿的关系不存在显著调节作用。  相似文献   

An Augmented Norm Activation Model: The Case of Residential Outdoor Water Use     

Adam C. Landon  Gerard T. Kyle  Ronald A. Kaiser 《社会与自然资源》2017,30(8):903-918

Understanding the factors that influence voluntary conservation is critical for developing effective residential water conservation policy. Previous work drawing on Schwartz’s Norm Activation Model (NAM) has been useful to understand some of these factors. However, one’s relationship with the broader community impacted by consumptive decisions has often been overlooked. Similarly, scholars have emphasized the importance of contextual factors not captured in the NAM. In this study we hypothesize and test an augmented NAM that incorporates community attachment, along with contextual variables (sociodemographic and household infrastructure), to understand the factors that lead to the development of moral obligations to conserve water and their relationship with residential outdoor water use. Results indicate personal norms, defined as a moral obligation to conserve water, are negatively related to outdoor water use, and that community attachment is a predictor of personal norms. Contextual factors are found to have an influence on outdoor water use.  相似文献   

休闲涉入与地方依恋对农民工留城意愿的影响——基于广州市的调研数据     

谭红娟  李美云  陈世雄 《热带地理》2021,41(3):505-515

在“认知－情感－行为意向”范式下,基于中国农民工流入地典型代表广州市的抽样调查数据,采用差异显著性检验和结构方程模型分析方法,探讨农民工留城意愿和地方依恋特征,并实证检验休闲涉入、地方依恋对农民工留城意愿影响的理论模型。结果表明：1）广州市农民工的留城意愿和地方依恋倾向较为强烈;2）不同个体特征的农民工群体在留城意愿和地方依恋上存在显著差异,人口学因素对农民工留城意愿和地方依恋作用突出。其中,学历高中或中专以上、月收入在2 001~4 000元、来穗工作年限超过1 a、来自中部和东部省份的广州农民工,其留城意愿最为强烈;3）休闲涉入对留城意愿的直接正向影响效应显著,地方依恋在其中存在显著的正向中介效果。且经过中介变量地方依恋的介入后,休闲涉入对留城意愿的直接效果显著弱化,间接效果相对显著增强。  相似文献   

Place-Based Pathways to Proenvironmental Behavior: Empirical Evidence for a Conservation–Recreation Model     

Lincoln R. Larson  Caren B. Cooper  Richard C. Stedman  Daniel J. Decker  Ryan J. Gagnon 《社会与自然资源》2018,31(8):871-891

This study expands existing models of proenvironmental behavior (PEB) to examine the potentially important and interacting influences of nature-based recreation and sense of place on participation in conservation-oriented activities. We tested hypothesized relationships using a structural equation modeling approach that accounted for common behavioral antecedents within a sample of 1,124 nature-based recreationists and property owners in rural counties of New York, USA. We found that place attachment played an important role in strengthening connections between nature-based recreation and PEB. Birdwatching and hunting participation contributed independently and significantly to PEB, both directly and indirectly through effects on place meanings and place attachment. While birdwatching appeared to influence place attachment by impacting environmental place meanings, hunting exerted similar effects by affecting sociocultural place meanings. Ultimately, our synthesis results in the articulation of a comprehensive conservation–recreation model that could help researchers and practitioners identify and explore novel pathways to PEB.  相似文献
