猛进水库水环境问题研究

猛进水库是五家渠地区的主要水源地,也是乌鲁木齐市重要的淡水鱼供应基地.近年来,猛进水库水质呈不断恶化的趋势,水质为劣V类,为此,猛进水库水质恶化问题已经成为各级政府及公众十分关注的问题.本文选用新疆水环境监测中心多年对猛进水库水质监测及调查的资料,对猛进水库水质现状进行分析评价,运用季节性肯达尔(Kendall)检验等方法,分析了猛进水库水质变化趋势及影响猛进水库水质的主要污染源,提出了进一步保护猛进水库水质的建议,为改善其水环境质量提供依据.     

新疆二噁英类POPs排放现状调查及分析

在对新疆二噁英类POPs排放调查的基础上，归纳了新疆二噁英类污染物的主要来源和分布情况，分析了新疆二噁英类POPs排放源在环境监管中存在的问题，并提出了相应的建议，对今后新疆二噁英类POPs排放的管理、控制和削减有重要意义。     

Comprehensive assessment of toxic metals in urban and suburban street deposited sediments (SDSs) in the biggest metropolitan area of China

A set of toxic metals, i.e. As, Hg, Pb, Cd, Cu, Zn, Ni and Cr, in urban and suburban SDSs were investigated comparatively in the biggest metropolitan area of China, Shanghai. Results showed that all of the metals except As were accumulated greatly, much higher than background values. Geo-accumulation index indicated that metal contamination in urban SDSs was generally heavier than that in suburban SDSs. Potential ecological risk index demonstrated that overall risks caused by metals were considerable. Cd contributed 52% to the overall risk. Multivariate statistical analysis revealed that in urban SDSs, Zn, Ni, Cd, Pb, Cu and Cr were related to traffic and industry; coal combustion led to elevated levels of Hg; soil parent materials controlled As contents. In suburban SDSs, Pb, Cu, As and Cd largely originated from traffic pollution; Zn, Ni and Cr were associated with industrial contaminants; Hg was mainly from domestic solid waste.

张家口地区生态可持续性评价研究

张家口市生态环境比较脆弱。经济上属于河北省落后地区，且近邻首都北京，因此它的发展不断引起人们的关注。本文选用了由加拿大生态学家Rees和Wackenagel等提出的生态足迹模型，对张家口地区进行可持续发展的定量测算。结果表明：张家口市自1990年到2000年一直处于不可持续状态，且人均生态赤字呈逐年增大的趋势。针对这种情况，本文提出全面发展精细农业、促进工业升级以及以“人”为本的区域发展对策。     

厦门海岸带湿地变化的研究

通过“压力-状态-响应”分析模型，对厦门海岸带湿地变化的主要原因（压力）、成分退化和结构改变（状态）以及对厦门海岸带生态系统的主要影响（响应力）之间的作用机制进行了探讨。提出厦门海岸带湿地面临的主要压力来自海岸带围垦造地、近海滩涂养殖和九龙江河口输入；状态变化突出表现在浅海海域面积的减少。红树林的面积减少。近岸泥沙淤积。沉积物类型改变和沉积物污染；主要影响是造成厦门海域水质下降、近海底橙生物类型改变、航道泥沙淤积、水产养殖产量下降和珍稀海洋物种分布和数量改变。

Uncovering the Connections Among Sustainability, Governance and GDP

This paper examines the connections among sustainability, governance and GDP, using the data from 123 countries. Sustainability is found to be related with GDP in two contradictory ways. On the one hand, growth in GDP strengthens a nation＇s ability to maintain favorable environmental conditions into the future. On the other hand, GDP growth is built on more consumption of natural resources, and therefore generates a larger ＂foot-print＂ on the Earth. Governance plays a key role in sustainable development. However, it is not helping to reduce our footprint on the Earth. In fact, good governance is linked to a larger footprint. This reflects our materialist value and human impulse. When a society prefers the comfort and wellbeing of human beings to the welfare of its environment, democratic governance might be used as an effective tool against nature.
