随着海洋旅游时代的到来,我国迎来了海洋旅游发展的良好契机,海洋型旅游城市作为重要的旅游目的地类型之一,其旅游竞争力近年来受到各界关注。文章从海洋型旅游城市特征出发,建立海洋型城市旅游竞争力评价指标体系,进而将海洋型城市旅游竞争力分为旅游资源竞争力、旅游基础设施竞争力、旅游行业竞争力以及旅游环境支持竞争力四大部分。进一步基于因子分析法和聚类分析法对我国51个海洋旅游城市的旅游竞争力进行实证分析,得出城市旅游竞争力得分排名。最后根据分析结果,从旅游资源、旅游基础设施、旅游产业、旅游环境支撑、整体旅游等方面提出我国海洋型城市旅游竞争力的提升路径,为促进我国海洋型旅游城市整体竞争力的提升提出指导建议。 相似文献

文章针对国内已有研究测度旅游消费增长较少,以及未考虑空间效应等不足,系统构建了基于旅游消费水平、旅游消费结构、旅游消费质量与旅游消费环境的旅游消费增长综合评价体系,测算2007—2018年沿海11个省(自治区、直辖市)旅游消费增长综合指数,并进一步运用空间杜宾面板计量经济模型,分析沿海地区的旅游消费行为、影响因素及空间效应。研究发现:近年来沿海地区旅游消费增长明显并存在显著的空间溢出,与旅游产业建设资金显著负相关,与旅游从业劳动力、技术创新及交通条件显著正相关。未来建议进一步加强沿海地区旅游消费增长的区域协同,推进旅游产业供给侧改革,优化提高旅游产业要素配置效率与发展质量,充分发挥旅游消费增长的空间溢出。 相似文献

游客口碑影响游客的消费选择和消费倾向,同时也对旅游目的地的形象塑造产生重要影响。目前我国旅游已进入全域旅游发展阶段,旅游目的地将掀起新一轮的建设,在此背景下,基于游客负面口碑研究其对旅游目的地形象塑造的影响就显得极为重要。文章通过网络文本收集游客对大连滨海旅游形象的评价和感受,从游客的视角出发,将游客负面点评网络文本数据作为研究对象,运用文本分析方法和扎根理论研究游客对大连滨海旅游形象的感知。研究发现,游客负面点评主要有5个主类目、13个次类目的消极感知因素,基于此分析了其对大连滨海旅游形象塑造的影响。为提升大连滨海旅游形象,提出了实施情感体验营销策略、完善旅游基础服务设施、健全旅游安全保障机制、提供高品质的旅游服务、营造舒适的旅游环境氛围的对策,为大连乃至同类城市旅游形象重塑提供重要依据,也丰富了以网络文本为数据来源的旅游目的地形象研究。 相似文献

The analysis of the structure of the cryolithozone, facies, and thicknesses of the Quaternary sediments and the results of the physicochemical mathematical modeling of the modern shelf of the western part of the Laptev Sea support the influence of the Late Pleistocene glaciations on the heat conditions and the distribution of the permafrost in the area. A ～200-m thick glacier formed under aerial conditions from atmospheric precipitation represented the metamorphosed snow cover. According to the modeling, the long-living (from 60?50 to 10?4 ky) glacier reduced the thickness of the permafrost rocks in the reviewed shelf area for 280–360 m. The Holocene marine transgression additionally decreased the thickness from 50–140 m on the inner shelf to 220–350 m on the outer shelf. The modern submarine cryolithozone 450-0 m thick is wide-spread in the studied region from the coast to the shelf boundary (isobaths of 130–140 m), where it pinches out at a distance of ～380 km from the coast at a depth of ～250 m above the sea level. 相似文献

We analyze the components of the carbon system of the Sevastopol bay waters and the balance of main sediment-forming substances
using the data of field investigations in 1998–2008. The interannual variations of total inorganic carbon and the equilibrium
partial pressure of carbon dioxide in the bay water are noted. An increase in the flux of carbon dioxide into the bay and
in the content of organic carbon in bottom sediments is revealed, and an explanation of this phenomenon is given. The priority
accumulation of organic carbon in the sediments of the bay is established. We assess the interannual variation in the relative
abundances of organic and inorganic carbon as an index of the carbon cycle stability. 相似文献

We generalize and analyze the state of investigations of the influence of river waters on the hydrologic structure of the
Black Sea. Specific features of the water, regime and hydrography of rivers flowing into the sea, data on the discharge of
rivers, and intrayear and interyear variability of the discharge are presented. We discuss and analyze works studying the
transformation of river waters, routes of desalinized sea waters, and their influence on the thermohaline structure and dynamic
regime of the sea.

We analyze the results of numerical calculations performed according to the three-dimensional interdisciplinary model of an
ecological system of the Black-Sea shelf zone near the estuary of the Danube. The complete system of equations of hydrothermodynamics
is solved together with transport equations of the advection-diffusion-reaction type used to describe the transformation of
a substance (nitrogen) between the components of the characteristic vectors of the ecosystem: plankton, detritus, and biogenic
elements (nitrates). We describe the distinctive features of the circumcontinental distribution of components obtained as
a result of numerical experiments and present arguments for the conclusion that the ecosystem of the Danube estuary water
area plays the role of a buffer zone between the press of the Danubian biogenic pollutions and the neighbouring areas of the
shelf zone and open sea.

Relationship between the path of the Kuroshio in the south of Japan and the path of the Kuroshio Extension in the east 总被引：2，自引：0，他引：2
A relationship between paths of the Kuroshio and Kuroshio Extension (KE) is investigated, using the satellite-derived altimetry
dataset of 1993–2008. When the Kuroshio takes the nearshore nonlarge meander path or typical large meander path and resultantly
goes through the deeper channel (about 2500 m) of the Izu-Ogasawara Ridge, the KE path adopts a relatively stable state with
the two quasi-stationary meanders. On the other hand, when the Kuroshio takes the offshore nonlarge meander path and then
passes over the shallower part of the Ridge (about 1000 m), the KE path tends to be convoluted, i.e., an unstable state. 相似文献

Ten years of semistationary studies of the interaction of the ice cover and the coastal relief of the Kandalakhsa Gulf in the White Sea allowed us to reveal the peculiarities of these processes in the warm and cold years and the mechanisms of the origination of ice forms, including ice tents, which govern the character of the tidal flats. Three dynamic fast ice zones are distinguished by their geomorphological location, morphology, and ice dynamics. The dependence of the mechanisms and volumes of the enrichment of the fast ice in the sediments on the coastal zone??s relief was established. At the coast of the Kindo Peninsula (Velikaya Salma Strait), the ice mostly contains fine-sandy sediments. Coarser sediments, including boulders, are occasional and frozen into the ice at the contact of the fast ice and the bottom. At the expense of the ice??s spreading by 4?C6 times in the warm years and 2?C4 times in the cold years, several thousand tons of sediments mostly from the tidal flat??s surface (100?C700 m3 from 1 km of coast in the wide tidal flats and <50 m3 on the steep coasts) are delivered to the water area. 相似文献

The methodology and the first results of the computations of the volumes, masses, and growth rates of the sedimentary body of the buried Black Sea basin are presented. Their temporal evolution reflects the regional paleogeodynamics, in particular, the reorientation of the vector of the relative movement of the Arabian and Eurasian lithospheric plates and the related intensification of their collision in the late Miocene-Pliocene. 相似文献

The spatiotemporal variability of the hydrochemical composition of the riverine runoff in nearmouth areas is presented using the example of selected rivers of the Arctic Basin. The temporal dynamics of the riverine nutrient runoff are mainly determined by the seasonal and interseasonal variations in the drainage basins. The spatial variations in the chemical composition of riverine waters in the near-mouth areas are mainly caused by the dynamics of the water flow and the river bed relief and, to a lesser degree, by biochemical processes. It is shown that the variations in the nutrient composition of the waters in near-mouth areas are comparable in magnitude to those at the river-sea geochemical barriers. 相似文献

We use many-year archival observations of hydrologic and hydrobiologic state of the Sea of Azov for the identification of
the structure of a model of its ecosystem. The ecosystem model, supplemented with expert estimates of bioresource consumption
(fish reserve), contamination level, and possible ecologic fines for violation of the sea natural state, is formalized by
the method of system dynamics. Hereat, the major part of influence functions is found in terms of observational data with
application of self-organization algorithms. We also present the results of simulated experiments with the model of the ecosystem,
which enable us to analyse scenarios of its behaviour under the influence of various external factors (wind, river discharge,
water exchange with the Black Sea, etc.).
