近年来随着社会经济的发展和人们消费观念的转变,旅游休闲逐渐占据了大众日常生活消费的一部分,其能让人们在游玩中得到身体和精神上的放松,也能对旅游地的经济和文化发展起到带动作用。乡村旅游是近年来旅游行业为顺应经济发展大趋势和满足大众日益变化的休闲需求,对传统旅游项目进行变革与调整所开辟出的一种特色旅游,逐渐成为未来旅游的重要组成部分。文章对乡村旅游发展与乡村文旅品牌建设进行了研究。 相似文献

<正>民族体育活动是一种自发的组织形式,随着社会经济的迅速发展,人们的休闲娱乐活动日益多样化,因民族体育活动是自娱自乐,不受外部力量的制约,大受欢迎,方兴未艾。随着体育旅游市场的不断发展,民族体育逐渐演变成了一种“假民俗”,以迎合游客的口味。但近年来,民族体育文化这一中华优秀传统文化的代表,却陷入了困境。虽然政府以非物质文化遗产的形式进行保护,也仅仅是把有关民族体育的相关资料,作为一种文化遗存, 相似文献

A model to represent the discolouration of dried powder of carrots as a function of temperature was developed. Two types of carrots, Asian and European, containing large amount of lycopene and β-carotene, respectively, were tested. The dried powder was stored under an atmosphere with O2and at three different temperatures, 5,20 and 35°C. The surface colour of the powder was monitored during storage by a Hunter colour ratioa/b. In the proposed model, the rate of oxidation was assumed to be represented by the product of the fraction of concentration of oxidized pigment at arbitrary time and a specific rate of oxidation of pigment. The rate parameters in the proposed model were calculated by fitting the experimental data with smooth curves by trial and error at the end of the induction period but before discolouration took place. The frequency constant and activation energy, expressing the temperature dependence of the rate parameters, were expressed by the Arrhenius relation. The simulation results of a Hunter colour ratioa/bof dried powder at 25°C showed good agreement with the experimental data, suggesting that the proposed model was effective for the prediction of discolouration of dried powder of both types of carrot. The use of the induction period in the manner described may enable the shelf life of dried powder to be predicted. 相似文献

The fractional outflow rate of water from the rumen, measured as the rate of disappearance of the chromium complex of ethylenediamine tetra-acetic acid, was related to a number of dietary factors. A multiple regression equation was derived which expressed fractional outflow rate as a function of the intakes of dry matter, ash, acid-detergent fibre and crude protein.The data analysed consisted of 243 observations for sheep on 59 diets, including forage, concentrate and mixed diets. The ranges covered by the data were: fractional outflow rate 0.7–3.6 day?1; dry matter intake 560–1400g/day; ash 4–30%, acid-detergent fibre 7–41%, crude protein 5–26 % of dry matter; there were no observations for sheep of less than 34 kg liveweight.The equation accounted for 56·3 % of the total variance. Between-sheep variance could not be calculated for the whole of the data but was undoubtedly substantial since, for a sixth of the data, it was known to account for 38 % of the total variance. 相似文献

从灾害经济学的角度探讨了城镇供水优化调度的必要性和可能性，认为在缺水不可避免的情况下，对供水进行优化调度可以减小缺水带来的损失，产生较好的减灾效益，特别是可以大大减小严重干旱的灾害效应。并根据水资源的特性，提出了缺水损失的计算模式以及优化调度的原则和方法。 相似文献
