Mapping and measuring place attachment

The concept of place attachment has been studied extensively across multiple disciplines but only recently with empirical measurement using public participation GIS (PPGIS) and related crowd-sourcing mapping methods. This research trialed a spatially explicit method for identifying place attachment in a regional study in South Australia. Our research objectives were to (1) analyze and present the spatial results of the mapping method as a benchmark for future research, (2) compare mapped place attachment to the more common practice of mapping landscape values in PPGIS that comprise a values home range, (3) identify how participant socio-demographic and home location attributes influence place attachment, (4) provide some guidance for mapping place attachment in future research. We found large spatial variability in individual place attachment and mapped landscape values using both area and distance-based measures. The area of place attachment is influenced by occupational roles such as farming or conservation, as well as home location, especially in coastal versus non-coastal contexts. The spatial distribution of mapped landscape values or values home range is related to, but not identical to mapped place attachment with just over half of landscape values located outside the area of mapped place attachment. Economic livelihood values, as an indicator of place dependence, and social values, as an indicator of place identity, are more likely to be mapped within the place attachment area. Aggregated place attachment across participants in the region showed similar spatial intensity to aggregated values home range, but area-based assessment of place attachment and values home range are distorted by edge effects such as a coastline. To further develop the mapping of place attachment in PPGIS, we identify knowledge gaps from our study and offer suggestions for future research design.     

非洲裔移民在穗宗教场所地方感特征及其形成机制——基于广州石室圣心大教堂的实证研究

宗教地理是文化地理重要的研究内容之一,但在中国相关实证研究仍不多见。结合半结构问卷调查和访谈,对广州石室圣心大教堂的非洲裔移民宗教场所地方感特征及其形成机理进行探讨。研究发现：非洲裔移民宗教场所地方依恋和地方认同发展快于地方依赖;非裔移民较强的圣地地方依恋同时存在较强的空间可替代性,但又由于区位等因素存在宗教功能之外的非可替代性;圣地地方依赖则因被宗教教义视为功利性而被掩盖。回归分析表明,社交和场所互动时间是指示地方感的最显著指标。随着非粤宗教文化的融合发展,宏观政治环境以及语言文化隔离等外生因素正对宗教地方感的提高产生重要影响。     

九寨沟地方特质与旅游者地方依恋和环保行为倾向的关系

引入地方特质作为外生变量,构建旅游者地方依恋与环保行为倾向的结构模型,运用验证性因子分析与结构方程模型方法,以世界自然遗产地九寨沟为对象,探讨了自然观光地地方特质与旅游者地方依恋和环保行为倾向的内在关系。结果表明：① 地方依恋的不同维度对不同类型的环保行为倾向的影响存在显著差异;② 地方特质对旅游者地方依恋具有显著的正向影响,表明九寨沟地方特质是旅游者地方依恋构建的重要因素;③ 地方特质通过地方依恋对旅游者环保行为倾向产生显著的间接影响,是解释九寨沟旅游者环保行为倾向的有效因子,也是旅游者地方依恋与环境行为倾向关系中重要的影响因素;④ 九寨沟地方特质不同维度的影响程度存在差异,显著的地方特质（自然环境属性）具有更明显的影响效应。     

硇洲马尾藻Sargassum naozhouense幼孢子体附着及原生态恢复

【目的】探究硇洲马尾藻(Sargassum naozhouense)幼孢子体附着的选择性及原生态位点固着人工藻礁对马尾藻海藻资源恢复效果。【方法】选用混凝土、黄泥砖、牡蛎壳、聚丙烯板、橡皮条、沥青等6种废弃物材质对硇洲马尾藻幼孢子体附着效果进行比较;将硇洲马尾藻于徐闻南山进行原生态位点投放,周年观察比较人工藻礁与自然藻礁生长差异,探究硇洲马尾藻资源恢复效果。【结果】(1)不同材质藻礁对硇洲马尾藻幼孢子体附着差异显著,附着效果依次为混凝土>黄泥砖>牡蛎壳>聚丙烯板>橡皮条,沥青完全没有幼孢子附着。(2)当年人工藻礁苗有性生殖苗较自然生态苗生长慢,第二年假根再生苗生长与自然苗生长无显著性差异。(3)人工藻礁苗成活率为29.2%,此后不出现消退死亡,并以假根再生维持种群的繁衍。【结论】混凝土是马尾藻原生态藻床恢复较理想的人工附着基,黄泥砖、牡蛎壳、聚丙烯板等废弃物也可用于天然硇洲马尾藻以及室内有性苗源的附着基。假根再生是马尾藻种群繁衍的主要方式,利用有性繁殖的幼孢子体附着于混凝土块上进行硇洲马尾藻原生态位点投放是短时间增加马尾藻资源的有效措施,可为硇洲马尾藻海藻资源恢复提供可行的方法。     

植物激素对海带配子体克隆附着的影响

实验研究 2 ,4 - D、KT、IAA、NAA四种植物激素对海带配子体克隆附着的影响。结果表明 :2 ,4 - D对附着有较明显的促附着作用 ,最有效浓度为 2 .5mg/L 和 5mg/L,其 4 h的附着率分别是对照的 2 .79倍和 2 .95倍 ;KT的作用较复杂 ,在浓度为 1mg/L 时 ,对附着有明显的促进作用 ,其 4 h的附着率是对照的 2 .3倍 ;IAA对配子体附着没有明显的促进或抑制作用 ;NAA对附着有抑制作用 ,浓度越高 ,抑制作用越强。     

旅游者生态价值观对其环境责任行为的影响——以岳麓山风景区为例

依据自我决定理论,构建以自我决定动机为中介变量、地方依恋为调节变量的调节中介模型,旨在从心理动机层面探讨旅游者生态价值观影响其环境责任行为的作用机制和边界条件。研究发现:生态价值观对内部和外部动机均有显著正向影响,并通过内部和外部动机进一步正向影响旅游者环境责任行为;地方依恋对生态价值观与内部动机之间的关系有显著正向调节作用。在制定景区生态环境保护和可持续发展策略时,应考虑利用旅游者生态价值观、地方依恋和自我决定动机的多层作用关系,以激发旅游者环境责任行为。     

城市街景绿地对居民心理健康的影响——以广州为例

随着城市建设用地飞速扩张,绿地作为稀缺资源,对居民心理健康具有重要影响。本文基于2015年广州市1273份居民问卷调查数据,并通过腾讯街景视图和机器学习算法提取街景绿地数据,考察街景绿地、地方依恋和心理健康之间的内在逻辑与机理,并对比本地居民和外来移民的差异。研究发现：① 街景绿地与居民心理健康水平呈显著的正相关关系;② 街景绿地与心理健康的关系受到中介变量地方依恋的影响,即街景绿地通过影响居民地方依恋,间接影响其心理健康水平;③ 对于本地居民,地方依恋发挥完全中介效应,即街景绿地对居民心理健康的影响完全通过地方依恋实现;④ 对于外来移民,地方依恋则发挥部分中介效应,即街景绿地不仅直接作用于居民的心理健康状况,而且通过影响居民的地方依恋间接提升其心理健康水平。     

Place attachment among retirees in Greensburg, Kansas

On 4 May 2007 an ef-5 tornado leveled 95 percent of Greensburg, Kansas. Because city leaders encouraged everyone to use “green” building techniques as they rebuilt their homes and businesses, not only has the return to normalcy been exceedingly slow, but some of the town's older residents feel that officials have overlooked their needs. These minor episodes of discord enabled us to learn what features are most important to people in retirement. The features include identifiable landmarks, a space in which to socialize, and age-specific businesses. We assert that the lessons learned in Greensburg are applicable to other communities with a sizable older population. As baby boomers rapidly enter retirement they will seek places to live that are elder friendly and enable them to effectively bond with place. As previous research attests, people who have a strong attachment to place commonly have a good quality of life.
