Locating and quantifying groundwater flow in many built-up areas are a priority with regard to its complete restoration. In this work, a hydrogeological survey of the surroundings of the Punta Begoña Galleries (Getxo, Bizkaia), built on a coastal cliff, was completed by using ground penetrating radar (GPR) testing. Thus, the preliminary characterization of soils and rocks in accessible areas of the cliff was first improved by hydrogeological information gathered from a single survey borehole, including permeability measurements by low pressure injection tests (LPTs) and continuous water level monitoring. As a complementary method, the non-destructive GPR technique was performed during both dry and wet hydrological periods and in tandem with the injection tests, providing more complete spatial and temporal images of water flows. Specifically, GPR allows mapping of flow paths in soils and assessing the continuity of fractures in rock masses. Altogether, this complementary approach provides greater knowledge of complex underground flow dynamics in built environments, thus making it easier to make decisions for their management.  相似文献   

浅地层剖面系统在福建沿海海底沉船调查中的应用     

李海东  胡毅  许江  林兆彬  刘伯然  王恒波  郑江龙 《海洋技术学报》2019,38(1)

海底沉船是水下文化遗产的一种重要类型和存在形式,利用综合地球物理手段对福建平潭、莆田及福州海域的海底沉船进行了探测研究,并重点探讨了不同浅地层剖面系统及不同探测频率在不同埋藏状态的水下文物调查中的应用。结果表明:浅地层剖面探测能够有效识别处于不同埋藏状态的沉船,尤其对探测埋藏海底面以下的沉船具有其他探测手段无法比拟的优势,但是探测频率的调节对目标物探测结果存在较大差异,对于埋藏式的海底沉船低频信号探测效果较理想。  相似文献   

江苏非物质文化遗产的时空分布及其影响因素   总被引：2，自引：0，他引：2  

韩顺法  徐鹏飞  马培龙 《地理科学》2021,41(9):1598-1605

以江苏为例,运用地理学相关方法将非遗的时空分布可视化,并探讨其分布的影响因素。研究表明：江苏非遗在时间上呈“迂回向南”发展轨迹,其数量和类型在不同阶段具有明显差异;在空间上呈聚集性分布,分别在苏州、扬州、南京、常州、镇江和南通形成6个高密度核心;通过地理探测器分析,得知河流水系、政策导向、历史文化和经济等因素对非遗的时空分布有较大影响。由此得出重视江苏大运河文化带建设、将非遗纳入文化生态系统内整体性保护、正视非遗与经济合理互动等启示。  相似文献

杨小菊  赵学勇  武发思  张正模  薛平  陈章  汪万福  张国彬 《中国沙漠》2021,41(6):54-64

采用2018年敦煌莫高窟第16窟窟内与窟区PM₁₀浓度及气象数据,分析PM₁₀时空分布特征及其影响因素。结果表明：（1）两处监测点PM₁₀浓度主要分布在50 μg·m^-3以下,受重污染天气影响较小;春、冬、秋、夏季依次降低,窟区PM₁₀浓度在春、冬季高于窟内,夏、秋季反之。（2）PM₁₀浓度3月最高,9月最低,5—9月窟内月均值高于窟区。PM₁₀污染日数窟内5月最多,而窟区3、5月较多。（3）PM₁₀浓度日变化曲线在春季和秋季呈“双峰”型,夏季和冬季呈“单峰”型。（4）在半封闭环境的洞窟内,沙尘暴发生前后,PM₁₀浓度达到极值及恢复至原来水平的时间均滞后于窟区。（5）在不同季节PM₁₀浓度与气温、风速和降水呈负相关。除秋季外,PM₁₀浓度与相对湿度、气压呈正相关。（6）窟区全年主风向为ESE,在冬春两季,此风向PM₁₀浓度最高,PM₁₀主要来自三危山前的戈壁滩、干涸的大泉河河道以及窟前裸露的地表积尘。  相似文献   

Management Challenges for Aboriginal Cultural Heritage in Peri-urban Queensland     

Rachele Wilson  Tristan Pearce 《The Australian geographer》2017,48(2):203-217

It is often assumed that places of cultural significance to Aboriginal and Torres Strait Islander peoples are protected under cultural heritage legislation such as the Aboriginal Cultural Heritage Act 2003 in Queensland. Such Acts are improvements on previous policies, which all but neglected Aboriginal cultural heritage. Nevertheless, the aims of policies developed at wider geographic scales, such as States within the Australian system, continue to be disconnected from the experiences of some local Traditional Owners. In this paper, we examine conflicts between non-local policy and on-ground management decisions for Aboriginal cultural heritage in peri-urban Queensland. We focus on the challenges of local Traditional Owners in peri-urban landscapes, basing our discussion on recent experiences conducting research on Indigenous land management in southeast Queensland. We examine three case studies: one in which colonial heritage values were prioritised over existing Aboriginal cultural heritage values, a second where local government failed to support a private landholder’s attempt to identify and protect a cultural heritage site, and a third where a cultural heritage site was protected but in a way that restricts the continuation of cultural practices. Developing more productive and equitable relationships between Traditional Owners and non-Indigenous decision makers, with regards to Aboriginal cultural heritage, requires new locally developed processes for engagement and we suggest how this could be achieved.  相似文献   

跨区域线性文化遗产类旅游资源价值评价——以长安-天山廊道路网中国段为例   总被引：3，自引：1，他引：2  

任唤麟 《地理科学》2017,37(10):1560-1568

跨区域线性文化遗产是一类特殊的旅游资源。基于其特殊性,以其各遗产点的价值评价作为整个遗产的价值评价;借助层次分析法、菲什拜因-罗森伯格模型,通过设定评分标准与评价等级,构建跨区域线性文化遗产旅游资源价值评价模型;实证分析认为提出的方法与模型能较准确地评价资源价值,长安-天山廊道路网中国段各遗产点价值均在优良等级及以上,其中27.3%为五级（特品级）资源,59.1%为四级资源,13.6%为三级资源,在旅游开发中应采取领先开发或重点开发、分区开发及加强遗产点历史文化挖掘与宣传普及等策略。  相似文献   

基于游客认同的文化遗产景区安全标识系统研究——以青城山-都江堰景区为例     

王颖梅  陶长江  胡家镜  曹兴平 《地域研究与开发》2017,36(2)

文化遗产景区安全标识系统作为传播信息和规范观赏行为的有效方式,已成为影响游客旅游体验和衡量景区服务水准的重要因素。借助实地考察与随机抽样问卷调查,以青城山-都江堰世界文化遗产景区为例,综合利用文献分析和数理统计验证,拟定11项安全标识测量指标以调查游客对景区安全标识系统的认同感,研究结果表明:游客普遍认同遗产景区安全标识系统的重要性,但多是从利己角度的直观考虑;游客对青城山-都江堰文化遗产景区安全标识系统认同度低,安全标识系统各构成要素急需改进,尤其是安全标识的设计和功能;游客对文化遗产景区安全标识系统的认同度并不完全受人口统计特征影响;游客对文化遗产景区安全标识系统的认同度受游客出游频率和旅游形式影响。建议文化遗产景区从完善安全标识布局和基本功能、强调景观感设计、规范安全标识系统文字和色彩、改进标识的视觉尺寸和开展定期检查维护方面实施优化。  相似文献   

基于景观基因“地域机制”的客家文化保护与传承开发——以湖南省炎陵县为例     

曹帅强  邓运员 《地域研究与开发》2017,36(4)

根据客家文化景观基因理论及其"地域机制",以客家扩展聚居区炎陵县为例,结合历史文献查阅和实地调研,发掘分析该县客家文化的景观基因。研究结果表明:(1)迁徙由来、地域背景分别是客家文化景观的共同基因、本土基因;(2)由共同基因以"反客为主"的作用方式与本土基因形成了地方客家景观本质特性的主体基因;(3)保护与传承意识形态是决定其主体基因能否在世代遵循并坚守着"原汁原味"文化传统和文化精神传承过程中的人为基因。基于这些独特基因构成内在相关联的地域机制而所表达的特征,提出了应加强客家文化景观基因的数字化保护管理、传承开发政策等对策。  相似文献   

Protecting Important Agricultural Heritage Systems (IAHS) by Industrial Integration Development (IID): Practices from China     

ZHANG Yongxun  HE Lulu 《资源与生态学报(英文版)》2021,12(4):555-566

With Globally Important Agricultural Heritage Systems (GIAHS) increasing in number around the world, their conservation has become a new international research theme. From the perspective of combining theoretical analyses and practical case applications, this study examines the Important Agricultural Heritage Systems (IAHS) conservation pathways and operation mechanisms through industrial integration development (IID). First, the theoretical framework of IID in IAHS sites was constructed according to the requirements of IAHS conservation, which include analyses of the connotation and basic principles of IID, the necessity of IID for IAHS sites, the resource conditions, and the IID pathways. And then based on the theoretical framework, the IID of Longji Terraces in Guangxi, Honghe Hani Rice Terraces System in Yunnan (HHRTS), Aohan Dryland Farming System in Inner Mongolia (ADFS), and Huzhou Mulberry-dyke & Fish-pond System (HMFS) in Zhejiang are analyzed systematically. The main finding is that IID is an effective pathway for IAHS conservation. However, the IID in IAHS sites must stress the ecological and cultural values of the resources; IID should be based on local resource advantages; and IID should attach importance to the combination of different policies and coordination between different stakeholders.  相似文献   

历史背景认知对殖民遗产旅游情感体验的影响 ——以广州沙面岛为例     

赵昭  张朝枝 《热带地理》2018,38(5):707-716

中国数量众多的租界本质是殖民统治时期的空间遗存,但随着时间的推移,一些历史背景已经被遗忘。以广州沙面为例,利用情感量表问卷对具备不同历史知识的340个样本进行认知与情感体验评价,探索历史背景认知对旅游者情感体验的作用与情感体验差异的产生原因。研究发现：1）愉悦、目标一致性与新奇/确定决定积极情感,自我投入决定消极情感;2）接受沙面历史背景介绍的旅游者情感体验更消极,认知评价具有显著差异。殖民历史背景认知通过降低旅游者的愉悦、目标一致性,减弱积极情感欢乐、喜爱,提升自我投入从而增强消极情感气愤、悲伤、畏惧;3）殖民历史认知是否导致情感体验趋于消极由个体的评价所决定。历史背景知识为旅游者带来深入旅游体验的同时不会影响旅游追求愉悦的本质,这为殖民遗产旅游的展示与管理带来新的启示。  相似文献
