江西龙虎山地区红层沉积相分析及与丹霞地貌发育关系研究——以仙人城景区为例

江西龙虎山地区以发育老年期丹霞地貌为特色,其成景地层为晚白垩世河口组红层,目前对这套红层的沉积相认识程度还比较低。龙虎山仙人城景区河口组出露厚度达百余米,沉积构造发育,且人工开凿的台阶可以直达山顶,这为沉积相分析提供了便利条件。根据野外露头岩性组成、沉积构造等特点,识别出6种岩相单元:无沉积构造砾岩、正粒序层理砾岩、逆粒序层理砾岩、平行层理砾岩、含砾砂岩、古土壤。砾石统计结果表明,砾石粒径范围主要为3~4 cm,最大可达12.5 cm,成分以紫红色凝灰岩为主,砂岩、花岗岩和石英次之、变质岩（主要是片岩）较少,磨圆度主要为次棱角状,其次为棱角状。在显微镜下,砂岩碎屑颗粒主要呈棱角-次棱角状,分选性较差,粒径为0.05~2.00 mm,主要由石英、长石和岩屑组成,总体具有结构和成分成熟度中等偏低的特点。野外露头宏观和室内显微分析结果表明,仙人城丹霞地貌的成景地层为河流主导的冲积扇沉积体系的产物。在龙虎山地区,丹霞地貌的空间分布与盆地冲积扇沉积相的平面展布具有较好的一致性,盆地边缘冲积扇成因的厚层砾岩为后期丹霞地貌的形成和演化提供了物质基础。      

Using hydro‐chemograph analyses to reveal runoff generation processes in a Mediterranean catchment

The paper deals with the hydro‐chemical analysis performed in order to reveal processes, sources, paths and timing of the runoff generation in an experimental catchment representative of the hilly, terrigenous and forested watershed in the Mediterranean humid eco‐region of southern Italy. The analysis is based on the data recorded at the outlet of the catchment during 2013–2014. A mixing law procedure was applied on discharge (Q) and electrical conductivity (EC) data, by using the Q–EC end members previously collected at selected groundwater, sub‐surficial and surficial stations. In this way, we found four bound curves delimiting fields in a Q–EC plot, each with hydro‐chemograph value ranges. At annual time scale, the analysis revealed a seasonal behaviour of the hydrological response, different for the wet period, when the aquifer is recharging, and the dry periods, when the aquifer is discharging, despite frequent summer rain showers. At event time scale, the catchment seems to show the behaviour of a typical hydro‐geomorphic threshold system. We interpreted this behaviour as due to a progressive addition of water from distinctive components (i.e. deep aquifer, riparian corridor, hillslope and hollow), each with originally different mechanisms of runoff production (i.e. groundwater, groundwater ridging, saturation excess, infiltration excess and soil pipe exfiltration) and response time. During the event, the contributing areas enlarge upward the riparian corridors and the zero‐order basins, where the aforementioned components become superposed and the mechanisms interact more and more. We hypothesize that the threshold values between different states of the system are defined by the intersections of the boundary curves on the Q–EC plot. Different patterns in the Q–EC hysteretic cycles are prevalently related to the pre‐event soil saturation and groundwater contributions to stormflow and recharge mechanisms.

地质公园旅游形象测量研究

我国旅游业已经从资源驱动、产品驱动、市场驱动进入了形象驱动的阶段,旅游形象策划成为旅游规划的热门话题之一,而旅游形象测量是旅游形象策划的基础和依据。地质公园具有地质与公园双重属性,与其他景区和公园有所区别,因此一般的旅游形象测量方法并不适用于地质公园形象测量。在回顾旅游目的地形象测量相关研究基础上,结合地质公园特点,认为在测量时必须遵循综合性、独特性及科学性三原则,试图构建了地质公园形象测量“天平”模型,分别从发射和接收两个角度来测量地质公园形象。

Uplift and denudation of Mt Sanqingshan Geopark,Jiangxi Province,China

Mt Sanqingshan, a global Geopark and world natural heritage site located in Jiangxi Province, China, is famous for its eroded granite peaks. The uplift and denudation history of the area has been reconstructed using fission track methods for the first time. Apatite fission track ages (AFTAs) cluster into three groups at ca. 25 Ma, 45–55 Ma, and 70 Ma. These ages can be related to ancient multilevel denudation planes at about 900, 1200, and 1500 m above sea level, respectively. The apatite data also reveal four cooling stages for the Mt Sanqingshan region, from ca. 90 to 65–60 Ma, 65–60 to 45 Ma, 45 to 20–15 Ma, and 20–15 Ma to the present, with cooling rates of 1.96°C, 1.18°C, 0.37°C, and 3.78°C per million years, respectively, and an average cooling rate of 1.80°C per million years. Calculated uplift rates are 0.055, 0.034, 0.011, and 0.11 mm year^?1 in the four stages, yielding uplifts of 4140, 570, 290, and 1940 m, respectively. The uplift rate of the last stage was significantly faster than that of the other three preceding stages, reflecting rejuvenation of Mt Sanqingshan, as a result of new tectonism. The average uplift rate at Mt Sanqingshan is 0.053 mm year^?1, and the average denudation rate is 0.048 mm year^?1, resulting in 3550 m of uplift and 2540 m of denudation relative to eustatic sea level. The 1010 m difference is very close to the average elevation of about 1000 m at present. A comparison of uplift–denudation histories for Mt Sanqingshan and Mt Huangshan shows that fission track results can be useful for defining geomorphological development stages.     

广州市区与增城市气象要素差异性分析

利用广州市区和增城市1982—2013年的气象观测资料,应用数据对比和相关分析的方法,从年际和季节变化两个角度,分析了两地气象要素的差异性;运用拉格朗日模式,模拟了2个个例的水汽来源,分析两站降水量差异性的可能原因。结果表明:城市热岛效应导致广州市区温度高于增城市,而相对湿度低于增城市;城市冠层作用使得广州市区风速明显低于增城市。差异性存在明显的季节不同,温度和相对湿度在秋季差异最明显,风速在冬季差异最明显,而降水量在夏季差异最明显。通过相关性分析得到两站的温度以及相对湿度的相关系数达到0.99和0.89,可利用经验公式联系两地的预报结果。HYSPLIT模式模拟水汽来源表明,不同的水汽来源可以导致广州市区和增城市降水先后顺序以及降水量的差异。
