Water is an important factor for the sustainable development of tourism. We constructed a comprehensive model of the tourism water footprint (TWF), including tourism sewage and water for management, and used the world heritage Mount Huangshan as an example. The results showed that the total TWF, which included green, blue and grey water of Mount Huangshan in 2012, was about 10.19 million m3/year, approximately per tourist 3.39?m3/day or 3387?L/day. Tourism sewage and food were the main factors of water consumption. The spatial transfer of TWF led the spillover of tourism environmental impact, not only affecting Mount Huangshan but the Huangshan City and even nationwide. Tourist flow and temperature had a highly significant positive correlation with the TWF. Quantifying the TWF can reflect the pressure of tourists on water resources, and provide an effective decision-making basis for rational use of water resources. 相似文献

Residential Enclosure,Power and Relationality: Rethinking Sociopolitical Relations in Southeast Asian Cities 下载免费PDF全文
Gabriel Fauveaud 《International journal of urban and regional research》2016,40(4):849-865
As in many other areas around the globe, enclosed residential spaces have proliferated in Southeast Asia since the 1990s. Recent publications have presented such gated communities as ‘porous enclaves', implying multiple socio‐spatial dynamics of movements through gates and walls. However, the enclave model does not suffice for analyzing the relational dynamics generated by enclosed residential estates. The concept of ‘ecotonal space' and social geography are used to show, in the case of Cambodia's capital Phnom Penh, that the enclosure and its borders are producers and products of multiple social, spatial, economic and political relations, both symbolic and material. Property developers assert their position as an emerging elite in the city's society and politics, a process based on different types of everyday relations they have with the inhabitants of their residential estates and territorial institutions. The enclosed residential estate can serve as a resource for deploying new power relations. Consubstantial with the neopatrimonial nature of the Cambodian economy and politics, this process is a response to the opacity and uncertainty of real estate markets and urban development. 相似文献

基于2008年和2004年福建省制造业产值,以县域为基本研究单元,采用K均值聚类法对66个研究单元进行聚类、合并,根据制造业集聚程度将福建省划分为核心区、中间区和外围区3个区域;并测算制造业空间结构的集中度以及产业结构调整对区域集中度变动的贡献率α和产业空间分布变动对制造业空间结构变化的贡献率β,结果表明:核心区制造业高集聚,但集中度呈下降趋势,中间区和外围区的制造业集中度有所上升,但相对缓慢;各产业类型的空间结构及变化均有较大的差异,集中度区域变动较为显著的产业主要有食品加工业、烟草加工业本地资源依赖型行业和皮革、毛皮、羽绒及其制品业等外向度高的行业;本地资源依赖型的木草加工、饮料食品业和原有发展基础影响大的设备制造业等行业的变化是影响福建省制造业空间结构变化的主要原因。 相似文献

Accounting for customer satisfaction in measuring hotel efficiency: Evidence from the US hotel industry 总被引:1,自引:0,他引:1
Customer satisfaction, though an important output, is often ignored in hotel efficiency studies. Our study provides empirical evidence that excluding customer satisfaction may lead to significant difference in the mean and ranking of hotel efficiency scores. We derive our hotel efficiency scores using the distance stochastic frontier method based on a balanced sample of leading hotel chains in the US. We present and compare the efficiency results from two models, one that includes customer satisfaction and one that excludes customer satisfaction. The study discusses the difference in efficiency scores between the models. It also elaborates on the efficiency scores of some individual hotel chains and provides directions for future research. 相似文献

An Input Distance Function (IDF) is estimated to empirically evaluate and analyse the technical and environmental efficiencies of 210 farms located in the Chaudière watershed (Quebec), where water quality problems are particularly acute because of the production of undesirable outputs that are jointly produced with agricultural products. The true IDF is approximated by a flexible translog functional form estimated using a full information maximum likelihood method. Technical and environmental efficiencies are disaggregated across farms and account for spatial variations. Our results show that there is a significant correlation between the two efficiencies. The IDF is used to compute the cumulative Malmquist productivity index and the Fisher index. The two indices are used to measure changes in technology, profitability, efficiency and productivity in response to the adoption of two selected Best Management Practices (BMPs) whose objective is to reduce water pollution. We found significant differences across BMPs regarding the direction and the magnitude of their effect. 相似文献

Using non‐parametric methods, we estimate the foregone rents due to credit, allocative, and technical inefficiencies of subsistence farmers in Southern India. The lost rents are estimated directly from the Nerlovian efficiency index, and the results suggest the largest foregone rents derive from allocative inefficiencies and then credit inefficiencies. Also, results suggest that farms without well access experience larger losses than those with well access. Econometric results suggest education, the presence of tank water management efforts, and well access influence the level of foregone rent due to allocative and Nerlovian inefficiencies. Educational activities and policies to encourage better management of tanks are considered important for lowering the foregone losses. 相似文献
