浙江璜山金矿床同位素地球化学研究

本文根据最新获得的两组矿石和含矿石英中流体包裹体的Ｒｂ－Ｓｒ等时线年龄数据和初始锶同位素组成及２１个新测定的矿石、石英及围岩（石英闪长岩）的铅同位素组成，讨论了璜山金矿床的成矿时代、矿床成因及物质来源等问题。 矿石及成矿流体包裹体的年龄分别为３５８±２２Ｍａ和３９６．９±３４．５Ｍａ，表明成矿时代为海西期，与该地区韧性剪切带形成时代（３２５～３９９Ｍａ）一致。初始锶同位素比值低，在０．７０４０～０．７０４２范围内，落在玄武岩（地幔锶）区内，且铅同位素具低μ值特征，落在岛弧铅与地幔铅演化曲线之间，说明成矿溶液及成矿物质均来自上地幔或下地壳源区，同时，矿石铅同位素组成与围岩（幔源型石英闪长岩）铅同位素一致，表明二者在来源上关系密切。     

Precipitation chemistry and corresponding transport patterns of influencing air masses at Huangshan Mountain in East China

One hundred and ten samples of rainwater were collected for chemical analysis at the summit of Huangshan Mountain, a high-altitude site in East China, from July 2010 to June 2011. The volume-weighted-mean （VWM） pH for the whole sampling period was 5.03. SO2- and Ca2＋ were the most abundant anion and cation, respectively. The ionic concentrations varied monthly with the highest concentrations in winter/spring and the lowest in summer. Evident inter-correlations were found among most ions, indicating the common sources for some species and fully mixing characteristics of the alpine precipitation chemistry. The VWM ratio of [SO]-]/[NO3] was 2.54, suggesting the acidity of rainwater comes from both nitric and sulfuric acids. Compared with contemporary observations at other alpine continental sites in China, the precipitation at Huangshan Mountain was the least polluted, with the lowest ionic concentrations. Trajectories to Huangshan Mountain on rainy days could be classified into six groups. The rainwater with influencing air masses originating in Mongolia was the most polluted with limited effect. The emissions of Jiangxi, Anhui, Zhejiang and Jiangsu provinces had a strong influence on the overall rain chemistry at Huangshan Mountain. The rainwater with influencing air masses from Inner Mongolia was heavily polluted by anthropogenic pollutants.     

The Moderating Effect of the Ski Resort Environment on the Skier’s Travel Radius under the Restriction of Skill Consumption

Starting from the skill characteristics of ski tourism, this paper discusses the impact of consumer skill on travel decisions, and the moderating effect of the ski resort’s comprehensive leisure environment (including the ski resort sports environment and the regional cultural tourism environment), in order to both understand their impacts on the travel distance characteristics of skiers and attempt to provide necessary research support for the development of China’s ski industry and the construction of destinations. Based on the data from multi-period visitor surveys, this paper constructs the consumption skill-travel radius decision-making influence model under the moderating effect of the ski resort comprehensive leisure environment. The results show three main characteristics. (1) The travel radius obviously differs among skiers with different skill levels. The skill level of skiers has a significant positive effect on the larger travel radius, and a significant negative effect on the smaller travel radius. That is, skiers with a higher skill level are more inclined to undertake long-distance skiing travel, while skiers with a lower skill level are more inclined to undertake short-distance skiing travel. (2) The comprehensive leisure environment has a significant moderating effect on the skiers’ travel radius, with a significant positive impact on enlarging the travel radius, while the influences on high-skill and low-skill skiers are significantly higher than on middle-skill skiers. (3) In the comprehensive leisure environment, there are differences in the moderating effect of the ski resort sports environment and the regional cultural tourism environment on the skiers travel radius, and the positive moderating effect of the ski resort sports environment on the high-skill skiers’ travel radius is more obvious. While the regional cultural tourism environment has a more obvious positive moderating effect on the travel radius of non-skiers and junior skiers, it is more conducive to promoting domestic travel. In general, the skier skill level in China was generally lower, and the ski resort comprehensive leisure environment optimization is conducive to overcoming the limitation of the travel radius caused by the disadvantageous skill level of consumers. However, to promote the development of China’s ski industry in the long run, it is necessary to focus on improving the consumer’s ski skill level, but prevent the risk of losing high-skill consumers overseas. In the course of improving the level of domestic ski sports facilities, we should also focus on the domestic leisure cultural tourism environment to better enhance the attractiveness of domestic ski destinations.

云微物理过程对黄山云滴谱离散度的影响

利用2008年4—7月、2009年5—8月和2011年5—9月黄山光明顶的云滴谱观测资料,对离散度和体积平均半径之间的关系进行了深入的分析和讨论。结果表明,随着体积平均半径的增大,离散度与体积平均半径之间的相关从正变成负,主要与活化、凝结、蒸发和去活化有关,与以往研究一致。在此基础上,进一步发现负相关比较弱,主要与碰并过程有关。当云雨自动转化阈值函数增大时,碰并增强,离散度与体积平均半径之间的相关性由负转正,且正相关性逐渐增强。碰并导致的正相关削弱了凝结和蒸发导致的负相关。此外,尽管云滴谱出现了双峰谱,但第一档强度(第一档浓度除以总的浓度)仍然可以很好地区分正负相关性。     

黄山花岗岩节理及对地貌发育的控制

黄山在印支-早燕山陆内造山之后,由于岩石圈的加厚,重力失稳,燕山晚期(早白垩世中晚期)发生岩石圈拆沉、岩石圈减薄,软流圈上涌,后造山伸展发育,地表浅部伸展、断陷盆地发育。早白垩世中期主要发育中酸性的岩浆活动;规模较小,多呈近东西向展布;早白垩世晚期,由于拆沉作用的加强,大规模的岩浆活动发育,以酸性花岗岩为主,规模大,多为岩基状,同时地表浅部断陷盆地内火山喷溢活动发育。区域构造应力场研究成果表明:发育于燕山晚期-早喜马拉雅期的伸展作用所计算的应力场特征则明显的表现为NW-SE的伸展,应力场主要表现为σ1NW-SE的伸展,σ2和σ3近于水平,为典型的伸展应力场;喜马拉雅运动使黄山不断抬升,同时经受风化剥蚀,在第四纪期间,新构造运动使黄山地区发生三次幅度不等的抬升,尤其是距今约200万年的更新世初期,影响了黄山山体更为急剧的上升和沿节理或断裂发育的沟谷强烈侵蚀下切,形成了高逾千米、翘首云天的花岗岩峰林。
