Construction of inorganic elemental fingerprint and multivariate statistical analysis of marine traditional Chinese medicine Meretricis concha from Rushan Bay

Meretricis concha is a kind of marine traditional Chinese medicine (TCM), and has been commonly used for the treatment of asthma and scald burns. In order to investigate the relationship between the inorganic elemental fingerprint and the geographical origin identification of Meretricis concha, the elemental contents of M. concha from five sampling points in Rushan Bay have been determined by means of inductively coupled plasma optical emission spectrometry (ICP-OES). Based on the contents of 14 inorganic elements (Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Se, and Zn), the inorganic elemental fingerprint which well reflects the elemental characteristics was constructed. All the data from the five sampling points were discriminated with accuracy through hierarchical cluster analysis (HCA) and principle component analysis (PCA), indicating that a four-factor model which could explain approximately 80% of the detection data was established, and the elements Al, As, Cd, Cu, Ni and Pb could be viewed as the characteristic elements. This investigation suggests that the inorganic elemental fingerprint combined with multivariate statistical analysis is a promising method for verifying the geographical origin of M. concha, and this strategy should be valuable for the authenticity discrimination of some marine TCM.     

Study on elemental fingerprint of traditional marine Chinese medicine oysters from Jiaozhou Bay, China

In order to investigate the relationship between the trace elements and the characteristics of the oysters, we analyzed the trace elements present in the germplasm of oysters from different producing areas in the Jiaozhou Bay. The element fingerprints were established to reflect the elemental characteristics of the oysters. Concentration patterns of the elements were deciphered by principle component analysis (PCA) and hierarchical cluster analysis (HCA). The six regions were discriminated with accuracy using HCA and PCA based on the concentration of 16 trace elements. The elements were viewed as characteristic elements of the oysters and the fingerprints of these elements could be used to distinguish the quality of the oysters.     

基于偏离-份额模型的福建省海洋产业结构分析

运用偏离-份额分析法对福建以及其它沿海省、市的海洋产业结构进行分析,结果表明:福建省海洋产业结构已渐趋合理,具有一定的结构优势,但海洋三次产业的整体竞争力较弱,应当进一步调整海洋产业结构,加大海洋科技和综合管理方面的创新力度,全面推进海陆统筹发展,促进福建省海洋产业竞争力的提高和海洋经济的可持续发展。     

中国传统认知取向视阈下的先秦海洋观探析

先秦思想家从以道观之、以人观之和以类观之三个认知向度建构了独具华夏文明特色的海洋观。以道观之揭示了海洋作为具体存在体现了某种世界原理,从形而上的层面回答了海洋"是什么";以人观之是在价值层面探讨了海洋对人"意味着什么";以类观之通过想象和联想的方式把海洋与人加以类比,探讨了海洋给予人在德性培养和政道方面的实践指导意义。能知层面的以人观之与所知层面的以道观之、以类观之彼此之间体现了事实认知与价值评价相互交错的关系。相比古希腊时期的海洋观,先秦的海洋观由于缺乏人与自然对立的认知向度,无法对海洋作更多的普遍知识的探究,所获海洋知识缺乏科学性和精确性,把海与人进行简单的比附弱化了对海洋本身的认知。

Silicon limitation on primary production and its destiny in Jiaozhou Bay, China VIII: The variation of atmospheric carbon caused by both phytoplankton and human

Statistical analysis on data collected in the Jiaozhou Bay (Shandong, China) from May 1991 to February 1994 and those collected in Hawaii from March 1958 to December 2007 shows dynamic and cyclic changes in atmospheric carbon in the Northern Pacific Ocean (NPO), as well as the variation in space-time distribution of phytoplankton primary production and atmospheric carbon in the study regions. The study indicates that the human beings have imposed an important impact on the changing trends of the atmospheric carbon. Primary production in the Jiaozhou Bay presents a good example in this regard. In this paper, dynamic models of the atmospheric carbon in the NPO, the cyclic variations in the atmospheric carbon, and primary production in the Jiaozhou Bay are studied with simulation curves presented. A set of equations were established that able to calculate the rate and acceleration of increasing carbon discharged anthropologically into the atmosphere and the conversion rate of phytoplankton to atmospheric carbon. Our calculation shows that the amount of atmospheric carbon absorbed by one unit of primary production in the Jiaozhou Bay is (3.21−9.74)×10⁻⁹/(mgC·m⁻²d⁻¹), and the amount of primary production consumed by a unit of atmospheric carbon is 102.66–311.52 (mgC·m⁻²d⁻¹/10⁻⁶). Therefore, we consider that the variation of atmospheric carbon is a dynamic process controlled by the increase of carbon compound and its cyclic variation, and those from anthropologic discharge, and phytoplankton growth.
