旅游资源资本化的机制和方法   总被引:2,自引:0,他引:2  
针对目前我国旅游资源开发和管理方面存在的突出问题以及旅游实践发展的需要,提出“旅游资源资本化”--一种新的以价值为导向的旅游资源开发管理的理念和方法,强调了旅游资源的价值性、所有性和收益性。在国家政策和法律允许的前提下,旅游资源的所有者将旅游资源作为一种资本形态,与货币资本、实物资本、人力资本等一起投入到旅游开发活动中,进行市场化的开发、经营、运作和管理,从而带来良好的经济效益、环境效益和社会效益,使旅游资源实现价值增值,而旅游资源的所有者也从中获得经营收益。深入探讨了旅游资源转化为旅游资本的内部机制、外部条件、实现途径、方法模式等问题,指出旅游资源资本化有利于拓宽旅游融资渠道、优化资源配置、提高旅游资源的利用效率和开发管理的水平,实现旅游产业的可持续发展.  相似文献

基于土地供应动态价格存在不确定性和期末土地资源的市场推广具有灵活性,土地资源的储备开发价值包括初始投资和期末看涨期权价值。根据欧式多资产期权方法,通过把收益的算术平均近似表达为几何平均的形式,多维问题可以转换为一维问题。参照一篮子期权的几何平均B-S期权定价模型,给出了基于实物期权的多项土地资源储备与开发的算术平均收益的夏普比率优化目标函数。数值计算表明,土地资源配置比例越是均匀,土地储备的期权价值越小。期权价值与配置比例反映为非线性关系。  相似文献

流域开发的外部性及其内部化   总被引:10,自引:3,他引:10  
流域是地表水的集水区域。流域问题的本质是水。水是可持续发展的基础和条件,是环境与发展问题的核心。流域开发是以水资源为先导和主体的综合资源开发。实现流域经济可持续发展实质就是实现流域水资源可持续开发和利用。外部性是流域开发的基本特征,水资源的特性决定了流域开发的外部性。实现流域开发的外部性内部化是流域经济可持续发展的关键。实现流域开发外部性内部化,必须界定流域资源产权,明确流域开发主体;建立税收-补贴体系,对水资源合理定价;坚持“排污者付费原则”;建立流域水资源市场,实现水资源资产化管理。同时,政府要加强流域的管理;建立健全水资源保护与流域开发的法律体系;普及保护环境和水资源的教育,建立节水观念;支持和鼓励流域开发企业实行外部成本内部化措施;调整产业结构,深化国有企业改革。  相似文献

近年来随着全球气候的变化,“低碳经济”概念应运而生,并备受国际社会关注。核电以其高效、清洁及供能的稳定性而成为各国追求“低碳经济”的必然选择。江西省位于长江中游,改革开放以来其经济发展长期落后于东部沿海地区,自“十五”后江西有了快速发展,但随之也带来了巨大的电力能源缺口及环境污染的加重。江西省尚未发现油气资源,煤炭及水能资源产量严重不足,一次能源主要靠外省调入,但江西有着较为稳定的地质构造、较为发达的水系和充沛的雨水、丰富的铀矿资源、以及象东华理工大学这样的核工业人才储备基地,因此,江西既有发展核电的必要性也有其可行性,发展核电既能为江西经济发展提供稳定的能源后盾又能保护环境、减少环境污染,从而实现江西省经济的跨越式发展。  相似文献

Measurements of ambient radiation doses and determination of radionuclide concentrations in mining waste and soils were performed in 60 areas of former radium and uranium mining. In several places, mining waste and low-grade uranium ore left on the surface contain radioactivity above regional background. Most of the former mining sites present no enhanced radionuclide concentrations. However, in the mining facilities where the radioactive ore was chemically extracted, mill tailings contain materials with elevated levels of radioactivity, up to 200 times the levels in unaffected soils of the region. Mud from neutralization ponds used to treat acid mine waters contains also elevated radionuclide concentrations. Furthermore, depending on the type of waste, the radioelement composition varies. Environmental rehabilitation measures shall take these differences into account in order to prevent in the long term the radioactive contamination of agriculture soils and water resources, and to ensure adequate radiological protection to the public and to the environment.  相似文献

Two former uranium mines and a uranium reprocessing factory in the city of Aktau, Kazakhstan, may represent a risk of contaminating the surrounding areas by uranium and its daughter elements. One of the possible fingerprinting tools for studying the environmental contamination is using plant samples, collected in the surroundings of this city in 2007 and 2008. The distribution pattern of environmental pollution by uranium and thorium was evaluated by determining the thorium and uranium concentrations in plant samples (Artemisia austriaca) from the city of Aktau and comparing these results with those obtained for the same species of plants from an unpolluted area (town of Kurchatov). The determination of the uranium and thorium concentrations in different parts of A. austriaca plants collected from the analyzed areas demonstrated that the main contamination of the flora in areas surrounding the city of Aktau was due to dust transported by the wind from the uranium mines. The results obtained demonstrate that all the areas surrounding Aktau have a higher pollution level due to thorium and uranium than the control area (Kurchatov). A few “hot points” with high concentrations of uranium and thorium were found near the uranium reprocessing factory and the uranium mines.  相似文献

The usefulness of uranium concentration in soil solution or recovered by selective extraction as unequivocal bioavailability indices for uranium uptake by plants is still unclear. The aim of the present study was to test if the uranium concentration measured by the diffusive gradient in thin films (DGT) technique is a relevant substitute for plant uranium availability in comparison to uranium concentration in the soil solution or uranium recovered by ammonium acetate. Ryegrass (Lolium perenne L. var. Melvina) is grown in greenhouse on a range of uranium spiked soils. The DGT-recovered uranium concentration (CDGT) was correlated with uranium concentration in the soil solution or with uranium recovered by ammonium acetate extraction. Plant uptake was better predicted by the summed soil solution concentrations of UO22+, uranyl carbonate complexes and UO2PO4. The DGT technique did not provide significant advantages over conventional methods to predict uranium uptake by plants.  相似文献

Hydroponicaly cultivated plants were grown on medium containing uranium. The appropriate concentrations of uranium for the experiments were selected on the basis of a standard ecotoxicity test. The most sensitive plant species was determined to be Lactuca sativa with an EC50 value about 0.1 mM. Cucumis sativa represented the most resistant plant to uranium (EC50 = 0.71 mM). Therefore, we used the uranium in a concentration range from 0.1 to 1 mM.Twenty different plant species were tested in hydroponic solution supplemented by 0.1 mM or 0.5 mM uranium concentration. The uranium accumulation of these plants varied from 0.16 mg/g DW to 0.011 mg/g DW. The highest uranium uptake was determined for Zea mays and the lowest for Arabidopsis thaliana. The amount of accumulated uranium was strongly influenced by uranium concentration in the cultivation medium. Autoradiography showed that uranium is mainly localized in the root system of the plants tested. Additional experiments demonstrated the possibility of influencing the uranium uptake from the cultivation medium by amendments. Tartaric acid was able to increase uranium uptake by Brassica oleracea and Sinapis alba up to 2.8 times or 1.9 times, respectively. Phosphate deficiency increased uranium uptake up to 4.5 times or 3.9 times, respectively, by Brassica oleracea and S. alba. In the case of deficiency of iron or presence of cadmium ions we did not find any increase in uranium accumulation.  相似文献
