Macroinvertebrate Regionalisation for use in the Management of Aquatic Ecosystems in Victoria, Australia

The development of a broader, more holistic approach to aquaticecosystem management has been called for in recent years. Physical and chemical objectives alone are no longer consideredsufficient for the protection of aquatic ecosystems and shouldbe supplemented with biological objectives. The ubiquitousand sedentary nature of macroinvertebrates, combined with theirmeasurable response to environmental conditions, favour their use as important indicators in environmental policies. To establish biological objectives, there is a need for a regionalframework to limit the variability between ecosystems. Past studies have demonstrated that an a posteriori regionalisationapproach may be more useful than an a priori approach in explaining single component (e.g. macroinvertebrates) patternsacross ecosystems. This is particularly important as aquaticresource management agencies often focus on one or twocomponents of the ecosystem to assess environmental health. This study uses an a posteriori method to delineate and describebiological regions based on edge and riffle macroinvertebrate data. The regionalisation will provide a framework for settingbiological objectives, based on the range of reference conditionsmeasured within each separate region. The objectives will includeregional checklists for taxa and biotic indices. Predictive modelling in the style of RIVPACS or AUSRIVAS will also be usedwithin each region to develop objectives, incorporating local, regional and systematic features as predictor variables.

A Study on Transfer Factors of 60Co and 65Zn from Soil to Plants in the Tropical Environment of Bangladesh

Soil to plant transfer factor (TF) of⁶⁰Co and ⁶⁵Zn was determined fromradioisotope experiments on plants grown in pots underoutdoor ambient tropical conditions for three growingseasons (1995–1998). The TFs were obtained fordifferent plants/crops such as, rice, bean, peanutspineapple, cabbage, tomato, spinach and grass. Theaverage TF values of ⁶⁰Co are found to be 0.087,0.15, 0.12, 0.67, 0.28, 0.79, 1.03 and 0.34respectively for the above mentioned plants/crops. Incase of ⁶⁵Zn, the average TF values are found tobe 2.24, 1.17, 0.89, 1.09, 0.78, 1.34, 2.92 and 1.78,respectively, for the above mentioned plants/crops. Thedata will be useful to assess the radiation exposureto man associated with the releases of radionuclidesfrom nuclear facilities by means of radiologicalassessment models that require transfer factors asinput parameters to predict the contamination ofradionuclides in foodchain.     

环境污染纠纷调处与环境行政处罚之区别浅析——兼与章锦华同志商榷

指出了环境污染纠纷调处与环境行政处罚的性质，程序，结果等均不相同，在理论上不能将两者混一谈，实践中应区别对待。     

基于耦合模型的安徽经济与环境协调发展分析

构建了经济发展与生态环境评价指标体系，选用耦合协调度模型计算2010—2019年安徽省不同区域经济发展与生态环境的耦合协调度，并采用灰色关联度法计算评价指标与耦合协调度的关联系数。研究结果表明：全省经济发展与生态环境的耦合协调度整体呈改善趋势，耦合协调度集中分布在0.393~0.765，基本处于良好协调或低水平协调阶段。全省不同区域的生态环境指数均大于经济发展指数。省会城市、沿江江南地区耦合协调度高于江淮之间和淮河以北地区。工业"三废"排放量、环境质量、环境污染治理力度是影响经济发展与生态环境耦合协调度的重要因素，建议通过改善这些方面进一步提升经济与环境的耦合协调度水平。     

“十四五”农村环境质量监测体系研究

介绍了国内外农村环境质量监测的发展历程和现状,总结了现行农村环境质量监测体系在体制机制、技术体系、应用支撑和数据共享等方面存在的主要问题,分析了"十四五"期间农村环境质量监测面临的挑战和机遇,指出"十四五"是农村生态环境保护的关键期、攻坚期和窗口期。根据环境管理对农业农村工作的新要求,构建了包括村庄、区域和流域3个层次及涵盖空气、地表水、饮用水、土壤、生态、污染点源和面源等监测内容的"十四五"农村环境质量监测体系,并提出了相应的保障措施,以期为我国农村生态环境保护提供更有力的技术支撑。     

我国海洋环境污染监测质量保证的回顾与展望

我国海洋环境污染监测质量保证的发展历史可大致分为三个阶段：孕育阶段（１９７２～１９７７年）起步阶段（１９７８～１９８３年）和发展阶段（１９８４～）。各个阶段有不同的特色和侧重点，１９７８年前主要探索与污染物质的分析方法，１９８４年后是监测质量保证工作进入管理时期。     

基于网格空间数据的晋陕蒙接壤区生态环境综合评价

晋陕蒙接壤区是典型的生态过渡带、生态脆弱带。文章在调查研究的基础上 ,选取了 1 3个评价指标 ,应用层次分析法确定其权重 ,并将各个因子分级标准化和定量赋值 ,再用加权求和法得到每个评价单元的环境质量综合评价指数。根据环境综合评价指数将环境质量分为较好 (≥ 8)、一般 (≥ 6～ <8)、较差 (≥ 4～ <6)、恶劣 (<4) 4级。结果表明 :晋陕蒙接壤区的环境质量大多处于较差等级 ,较好、一般、较差、恶劣等级的面积比例分别为 2 .2 % ,2 8% ,5 7.4%和1 2 .4%
