An Experience Inspired by the Evolution of Community Gardens in New York City     

ZHENG Jie  LYU Yating 《资源与生态学报(英文版)》2022,13(2):299-311

In many highly dense urban environments, the urgent needs of residents for increasing green space, improving the quality of the community environment and reconstructing the relationships among residents have given birth to the new space type of community gardens. However, China still lacks this relevant experience. In contrast, New York City’s community gardens had a relatively early start, and they now have rich experience in space construction, operation and maintenance. Given their level of experience, they can be used as references for the development of community gardens in China. This paper adopts a bibliometric research method, identifies 201 periodical literature sources published between 2000 and 2020 from the core library of the Web of Science as the object of study, and finally assesses the research hotspot for transferring from macro-research to space-type construction method, social impact, and so on, through CiteSpace software analysis. By virtue of the research process analysis and the results of field surveys and interviews, this paper probes the development status of space construction and social organization construction of the community gardens in New York City, and summarizes that area’s effective experience of development. Based on the current development situation of China’s community gardens, it is proposed that the development of community gardens should be directed by ensuring the land for development, giving full play to social benefits, and mobilizing social organizations, so as to effectively realize urban space construction and social governance.  相似文献   

中国城镇建设用地投入效益研究   总被引：2，自引：0，他引：2       下载免费PDF全文

 面对人多地少、位处工业化、城镇化加速发展阶段的现实状况,如何合理、有效配置（利用）土地资源成为我国当前可持续发展研究中的重要内容,而城镇建设用地投入效益评价则为土地资源的合理配置提供了理论依据和科学参考,为此对其进行评价具有重要的理论和现实意义。基于城镇建设用地投入效益的界定,认为其是一个基于生产性要素投入产出效率、人工复合生态系统内在经济、社会、生态环境效益耦合协调性、空间载荷强度及区域关系、制度安排合理程度的客观反映,据此构建评价体系,并以我国30个省（自治区、直辖市）为研究单元进行实证研究。结果表明：（1）我国城镇建设用地投入效益呈现出：水平特征——粗放、低效增长,内在经济、社会、生态环境系统耦合协调水平低,空间特征——分异明显,整体呈现出东部地区>西部地区>东北地区>中部地区的地理格局;（2）经济效益（3.500 5）>社会效益（3.019 3）>生态环境效益（1.332 9）的格局,在某种程度上映射出我国现有的宏观发展战略,存在重公平、忽视效率的弊端,严重扭曲了区际价值关系（“人人”矛盾尖锐）。为各省区配置城镇建设用地,进行区际生态补偿、财政转移支付以及省区内社会、经济、生态环境的协调可持续发展等提供了参考。  相似文献

居民对遵义红色旅游商业街中书法景观的认同度研究     

肖潇  张捷  卢俊宇 《地理科学进展》2012,31(8):1080-1086

文化地理学作为人文地理学的重要分支, 是学者们广泛关注的热点, 但鲜有研究涉及居民对文化景观的感知和认同问题。本文选取了中国传统文化代表--书法景观为研究切入点, 根据地方感理论构建了假设模型, 提出了17 个假设影响路径。根据遵义会议会址景区及周围红色旅游商业街中书法景观的居民感知调查数据, 构建了居民书法景观感知的结构方程模型。分析结果验证了居民感知态度与文化认同的递进性, 拒绝了部分研究假设。同时, 在书法景观功能感知的5 个维度:经济获益、环境审美、场所识别、景观原真性和行为导向中, 经济获益和景观原真性是居民文化认同的决定性因素。研究结果体现了原真性元素在城市文化景观中的核心地位, 验证文化景观对城市经济建设不可或缺的推动作用, 对城市文化景观保护和规划管理具有重要的指导和借鉴意义。  相似文献   

Spatial assessment of fishing effort around European marine reserves: implications for successful fisheries management   总被引：7，自引：0，他引：7

We examined the spatial dynamic of artisanal fishing fleets around five European marine protected areas (MPAs) to derive general implications for the evaluation of MPAs as fisheries management tools. The coastal MPAs studied were located off France, Malta and Spain and presented a variety of spatial designs and processes of establishment. We developed a standardized methodology to define factors influencing effort allocation and to produce fishing effort maps by merging GIS with geostatistical modelling techniques. Results revealed that in most cases the factors “distance to the no-take”, “water depth”, and “distance to the port” had a significant influence on effort allocation by the fishing fleets. Overall, we found local concentration of fishing effort around the MPA borders. Thus, neglecting the pattern of fishing effort distribution in evaluating MPA benefits, such as spillover of biomass, could hamper sound interpretation of MPAs as fisheries management tools.  相似文献   

Global assessment of the European Union fishing fleet: An update   总被引：1，自引：0，他引：1  

Sebastian Villasante 《Marine Policy》2010

This paper provides a global analysis of recent trends in the EU fishing fleet. Analysis of the capital productivity, labour rates, and economic benefits of the fleet revealed that considerable replacement of fishermen by better technology and well-equipped vessels occurred between 1990 and 2006. The analysis confirms that the Common Fisheries Policy (CFP) has been ineffective in reducing fishing capacity. In addition, the changes in capacity that occurred in this time interval differed among the different sectors of the fleet. Some members of the high sea fishing fleet increased their capacity (range 11–57%), and the deep-sea sector, which has greater tonnage and fishing power, increased its fishing capacity by 34–44%. These results confirm the ineffectiveness of the CFP in reducing overcapacity and illustrate the continuing threat of overcapacity to the long-term sustainability of fishery resources.  相似文献
