打造过硬品牌 以彰显地质公园在UNESCO世界级名录中的特殊地位——PPF理念(“过去—现在—将来”理念)     

盖伊-马提尼  张志光  顾琰菲  李薇 《地球学报》2013,34(2):229-232

目前世界地质公园网络(GGN)共有90个成员, 分布在27个国家和地区, 尽管在这个网络建立过程中, 联合国教科文组织起着关键作用, 但在过去十多年里, 其与地质公园的关系只能被定义为“特别支持”, 眼下两者的关系应该在一个国际倡议或计划下被正式化, 这将有利于进一步提高地质公园的管理、交流合作和资源利用。实现该目标, 就要清晰地阐明地质公园核心的独有特色, 使地质公园与联合国教科文组织已实施的计划形成互补, 不会产生冲突或重叠。本文介绍的PPF理念将会是一个有效的方法, 以此创建一个过硬的品牌, 彰显地质公园在UNESCO世界级名录中的特殊地位。  相似文献

Release of mercury from intertidal sediment to atmosphere in summer and winter     

LIU Ruhai Under the auspices of National Natural Science Foundation of China 《中国地理科学(英文版)》2010,20(2):99-105

The release of mercury from intertidal sediment to atmosphere was studied based on the simulated experiment. The experiment samples were collected from the Haibo Estuary (S1) and the Licun Estuary (S2) of the Jiaozhou Bay in China,which are seriously polluted with mercury. The results show that the mercury in sediment releases rapidly to atmosphere under solar radiation. After 8 hours of solar radiation,mercury concentrations decrease from 5.62 μg/g and 2.92 μg/g to 2.34 μg/g and 1.39 μg/g in S1 and S2 sediments respectively in summer,and decrease from 5.62 μg/g and 2.92 μg/g to 4.58 μg/g and 2.13 μg/g respectively in winter. The mercury species in the sediment change markedly under solar radiation. The concentrations of mercury bound to organic matter decrease significantly from 2.73 μg/g to 0.31 μg/g in S1 and from 2.07 μg/g to 0.31 μg/g in S2,and the released mercury mainly comes from mercury bound to organic matter. Mercury flux shows distinguishing characteristic of diurnal change,and it increases rapidly in the morning with the rising of solar radiation intensity,but decreases in the afternoon. The mercury flux increases with sediment temperature and solar radiation intensity. The rapid release of mercury in intertidal sediment plays an important role in the regional mercury cycle.  相似文献

EXPERIMENTAL DESIGN IN CHEMOMETRICS     

STANLEY N.DEMING JOHN A.PALASOTA JOSEPHINE M.PALASOTA Department of Chemistry University of Houston  Calhoun Ro  Houston  TX -  U.S.A. 《地理学报(英文版)》1991,(3)

Chemometrics is defined as the application of mathematical and statistical methods to chemical systems.Systems theory is seen to be useful for organizing and categorizing the inputs to and outputs fromchemical systems.Advances in measurement science in the 1950s and 1960s,particularly in analyticalchemistry,created a need for a multivariate approach to data analysis.Early chemometrics emphasizedthe use of structure-finding methods for existing data sets.In many instances,data sets can be obtainedfrom designed experiments.Such data sets are more likely to contain the desired information and the datacan usually be acquired at less cost.Renewed interest in statistical process control will provide many new,more robust data sets in the future.  相似文献

1INTRODUCTIONForests are one of the major natural resources that per-form important environmental and recreational func-tions (COSTANZA and GROOT, 1997). It is well known that forests can absorb atmospheric carbon, maintain a certain degree of humidity in atmosphere, regulate rainfall, moderate temperature, and restrain soil erosion, etc. (AURELIA, 2003). So, the health of a forest in any given area is a very important indicator of the ecological conditions. But fire is the great…  相似文献
