温地公园概览

湿地公园（Wetland Park）的概念类似于小型保护区．但又不同于自然保护区和一般意义公园的概念。根据国内外目前湿地保护和管理的趋势．兼有物种及其栖息地保护．生态旅游和生态环境教育功能的湿地景观区域都可以称之为“湿地公园”，     

居民对泉州湾滨海湿地资源和环境的感知研究

中国的部分滨海湿地是资源、环境问题突出和人地矛盾非常尖锐的区域,在这些区域开展当地居民对资源、环境的感知研究有利于确定滨海湿地保护的宣传教育重点,引导新闻媒体、非政府组织和社区的积极参与。以中国东南沿海河口海湾重要湿地——泉州湾湿地为例,采用野外实地考察、抽样问卷调查和访谈等方法分析居民对滨海湿地资源和环境的感知,调查结果用SPSS软件进行处理。研究结果显示,当地居民因教育水平较低,环保意识较淡薄,对滨海湿地资源和环境感知状况存在不确定性。

Hydrogen isotope of individual n-alkanes from modern sediments and their application to environments

Hydrogen isotopes are commonly fractionated to a much greater extent and as a result display larger variations in δ values, In terms of the hydrogen isotope ratios of individual n-alkanes of 16 samples of modern sediments selected from four different locations in the southern part of Gansu, China, the δD values for most of the n-alkanes varied from -150‰-300‰, Variations in δD also occurred between different ranges of n-alkanes, effects of environmental changes on the hydrogen isotopic compositions of individual n-alkanes have been detected. Besides the δD values of n-alkanes, the δD values of lipids including pristane （Pr）, phytane （Ph） were also examined, by the combination of D/H ratios with molecular fingerprinting, Our results further support the notion that hydrogen isotopes of n-alkanes from modern sediments can act as paleoclimatic and paleoenvironmental proxies and provide invaluable new sources of information in the research of paleoenvironment reconstruction.     

Speciation of sulfate components in size-fractionated aerosol particles using sulfur K-edge X-ray absorption near-edge structure （XANES）

Sulfates are a main constituent of aerosols, which sulfate aerosols, it is necessary to determine what can cause various environmental problems sulfate ions are contained in these aerosols In the evaluation of the influence of In this study, sulfur K-edge XANES was used to determine sulfate species present in size-fractionated aerosol particles based on the post-edge structure after the main absorption peak in the XANES region. Aerosol samples were collected as part of the Japan-China joint project, ＂Asian Dust Experiment on Climate Impact＂ using a low-volume Andersen-type air sampler. XANES was measured at Beamline BL-9A at Photon Factory, Japan. A comparison of the XANES spectra of reference sulfate materials and aerosol samples collected in Tsukuba in Japan clearly showed that （NH4）2SO4 was the main sulfur species in particles with a smaller diameter and gypsum was the main sulfur species in particles with a larger diameter. A simulation of the XANES spectra by reference materials allows us to obtain the quantitative mixing ratios of the different sulfate species present in the aerosol samples. The presence of minor sulfur species other than （NH4）2SO4 and gypsum at the surface of mineral aerosols is suggested in our simulations and by a surface-sensitive conversion electron/He-ion yield XANES. In the absence of a contribution from a large dust event, the mole concentration of gypsum in the mineral aerosol fraction determined by XANES is similar to that of Ca which is determined independently using ion chromatography. This shows that the Ca and sulfate in the mineral aerosols are present only as gypsum. Considering that calcite is the main Ca mineral in the original material arising from an arid and semi-arid area in China, it is strongly suggested that gypsum is formed in aerosol during its long-range transportation by a reaction between calcite and sulfate ions.     

Effects of human activities on mercury in the environment in Xi＇an area, China

Effects of mercury on ecosystems and human health are well documented. Human activities have significant impacts on transport, transformation, and fate of mercury in the natural environment. In this study, a gold mining area （Tongchuan）, an urban area （Xi＇an）, and a historical site （Qinshihuan Tomb） in Shaanxi Province, China, was chosen to study the effects of human activities on the transport, transformation, and fate of mercury in the area. Samples of atmospheric precipitate, soil, sediment, pomegranate, corn and those from wells and the rivers that flow through or flow by the city and from the mining area were collected. The EPA methods were used for sample preparation and analysis of these samples. These methods combine acid digestion, chemical reduction, purge and trap with Cold Vapor Atomic Fluorescence Spectrometry （CVAFS）. Preliminary results showed high total mercury concentrations in the water samples collected from a river in Tongguan County. The total mercury concentrations ranged from 133 to 188 ng/L in the water samples collected from the rivers flowing through Xi＇an City. The amount of total mercury in the soil/sediment samples which were collected in the vicinity of Xi＇an ranged from 31.8 to 83.2 ng/g. The total mercury concentrations in the samples of atmospheric precipitate （including rain and snow collected from Sep. 2005 to Jan. 2006） ranged from 106-298 ng/L.

实践活动：新地理课程的亮点

众所周知，地理学是研究人类生存和发展的地理环境，以及人类与地理环境关系的一门科学。它既具有科的属性，同时也具有理科的属性。但是长期以来，中学地理一直被视为科，使中学地理不能以其本来完整的面貌展现在学生面前。因此，在中学地理课程中开设地理实践活动课，意义重大、影响深远，因为这不仅涉及到学生学习方法的改革，也涉及到教师教育、教学方法的改革，更重要的是涉及到教学观念与地理观念的更新。
