城市意象与旅游目的地意象研究中的趋同与分野   总被引：2，自引：1，他引：1

“意象”是近年来多学科研究追踪的热点命题之一。本文在重点文献回顾基础上,就城市意象和旅游目的地意象的研究发展脉络及方法进行了较为全面的回顾与分析,研究结果显示：二者的产生、发展与国际、国家的整体发展水平与人类的社会性需求存在密切联系,而这种社会性需求也决定了其研究的基本发展方向。就城市意象和旅游目的地意象研究本身来看,二者在研究的核心聚焦内容、研究的基本指向、研究方法与研究发展的外生动力上都基本趋于一致;在研究涉及群体与研究学科视角上存在明显的差别。同时,为了推进城市意象与旅游目的地意象研究的深化,提出了应关注“意象”的地方感研究与提升研究技术的具体建议。  相似文献   

上海世博会对周边城市旅游辐射效应研究   总被引：1，自引：0，他引：1  

王利鑫  张元标  王祥超 《地理与地理信息科学》2011,27(3):105-108

为了研究上海世博会对上海周边城市的旅游辐射效应以及对该地区旅游经济产生的影响,引入旅游辐射场强模型、旅游断裂点、旅游集中系数进行量化分析,结果表明:1)世博会使上海对周边城市的旅游辐射效应明显增强;2)世博会对周边城市的旅游辐射效应分布并不均匀,不同城市之间存在较大差异;3)上海在对周边城市的旅游辐射中占优势地位,世博会的举办使这种优势得以加强;4)世博会使上海及其周边地区的旅游经济趋于集中发展。  相似文献   

枣庄市峄城区矿山开采现状与地质环境治理探讨     

王海涛  邸勇  王森 《山东国土资源》2011,27(2):46-48

根据枣庄市峄城区矿山开采对地质环境造成的破坏及对矿业可持续发展调研分析,认为开采不仅对山体、植被等造成了直接破坏,还导致诸如地表塌陷、山体滑坡等安全隐患,矿山环境治理要从思想上、经费上、法律法规上、技术上入手解决,对已关停矿山地质环境治理,除加大宣传力度外,重点落实对矿山地质环境治理工作的责任、治理规划的编制实施,不断完善、探索治理方法和治理技术攻关及对策预案工作。  相似文献

Mobility of major ions and nutrients in the unsaturated zone during paddy cultivation: a field study and solute transport modelling approach     

N. Rajmohan  L. Elango 《水文研究》2007,21(20):2698-2712

Study of the movement of water and solute within soil profiles is important for a number of reasons. Accumulation of prominent contaminants from agricultural chemicals in the unsaturated zone over the years is a major concern in many parts of the world. As a result, the unsaturated zone has been a subject of great research interest during the past decade. Hence, an intensive field study was conducted in a part of Palar and Cheyyar river basins to understand the variation of major ions and nutrients in the soil zone during paddy cultivation. The chloride and nitrate data were used to model the movement of these chemicals in the unsaturated zone using the HYDRUS‐2D model. The field study shows that fertilizer application and irrigation return flow increases the major ions and nutrients concentration in the unsaturated zone. Further, the nutrient concentrations are regulated by plant uptake, fertilizer application and infiltration rate. Additionally, denitrification and soil mineralization processes also regulate the nitrogen concentration in the unsaturated zone. The solute transport modelling study concluded that the simulated results match reasonably with the observed trends. Simulated concentrations of chloride and nitrate for a 5‐year period indicate that the concentrations of these ions fluctuate in a cyclic manner (from 60 to 68 mg l^?1 and from 3·4 to 3·5 mg l^?1 respectively in groundwater) with no upward and downward trend. The influence of excessive fertilizer application on groundwater was also modelled. The model predicts an increase of about 17 mg l^?1 of chloride and 2·3 mg l^?1 of nitrogen in the groundwater of this area when the application of fertilizers is doubled. The model indicates that the present level of use of agrochemicals is no threat to the groundwater quality. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

A light and transmission electron microscopic study ofHexamite capsularis sp. nov. (Diplomonadina: Hexamitidae) in fish (Xenocypris dividi)     

Xiao Wu-han  Li Lian-xiang 《中国海洋湖沼学报》1994,12(3):208-212

A diplomonad flagellateHexamita capsularis sp. nov. from the posterior intestine of the fish (Xenocypris dividi) from Liangzi Lake, Hubei Province, is described. The flagellate was oval, with smooth surface and homogenous cytoplasm, 6.21±0.28 μm in length, 3.43±0.48 μm in width and with an elliptical capsule. Two recurrent flagellae arranged between two nuclei ran longitudinally to the posterior end. Fibrillar bands connected the accessory organelles of two cytostomal tubes, the body depressed at the posterior end of the body. This work is a part of the M. S. thesis of Xiao Wu-han and was supported by the National Natural Science Foundation of China (Grant No. 3870489).  相似文献
