移动床生物膜反应器—膜生物反应器深度处理模拟废水及工业园区综合废水

将移动床生物膜反应器(MBBR)与膜生物反应器(MBR)有机结合,研究了该MBBR—MBR串联系统在水力停留时间(HRT)为17.50、11.75h条件下的脱碳脱氮的效果以及对工业园区综合废水污染物的去除情况。结果表明:(1)MBBR—MBR串联系统脱碳脱氮的效果良好,HRT的改变对系统的去除效果有一定的影响,随着总HRT由17.50h变为11.75h,模拟废水中COD的去除效果降低,但氨氮、硝态氮和TN的去除效果基本不受影响。(2)MBBR—MBR串联系统处理印染工业园区综合废水也有较好的效果,当进水COD、氨氮分别为150~450、20~40mg/L时,出水COD、氨氮平均分别为53.1、1.8mg/L,MBBR—MBR串联系统对COD、氨氮的去除率平均分别为80.4%、93.1%,但系统对TN的去除效果不是很理想。     

改造集散市场 建设新型再生资源回收利用体系

目前“三位一体”（回收网点→分拣中心→集散市场）回收体系模式,因集散市场功能单一、产业链短,不能带动行业走向产业化。回收网点建设适应我国国情,而集散市场成为先进的完整的回收体系的短板。按照示范基地建设标准,把集散市场改造升级为拥有深加工利用产业链,拥有平台支撑优势,能够进行资源的规模化高值化利用的产业园区。把回收和利用两大产业板块融合一体,是再生资源产业化的发展方向。     

旅游产业园：理论模式与实践发展

旅游产业集群式发展成为新的发展趋势和现实要求,但目前国内仍存在多种发展模式。笔者认为,旅游产业园应特别突出旅游产业特色,既要考虑传统的观光度假功能,更应考虑上下游的旅游装备研发制造、旅游商品研发生产、旅游产品营销推广等各个环节。以鄱阳湖生态旅游产业园为例,分析了该产业发展模式的建设背景、战略意义、发展定位和建设内容。     

工业园区低碳发展模式评估与规划分析

通过对工业园区低碳发展模式的评估,分析其低碳发展的能源特征、经济特征与人力特征,并确定工业园区二氧化碳减排的潜力能源。基于能源-碳减排(EC)、经济-能源-碳减排(EEC)和人力-经济-能源-碳减排(HEEC)三种不同情景,在未来发展的一定规划期内,对工业园区具有二氧化碳减排潜力的能源进行规划分析,确定其年递减率,从而实现工业园区不同情景下的二氧化碳减排。通过实际案例研究,证明了评估与规划分析模型的可行性。     

Evaluation of the National Land Cover Database for Hydrologic Applications in Urban and Suburban Baltimore,Maryland1

Smith, Monica Lipscomb, Weiqi Zhou, Mary Cadenasso, Morgan Grove, and Lawrence E. Band, 2010. Evaluation of the National Land Cover Database for Hydrologic Applications in Urban and Suburban Baltimore, Maryland. Journal of the American Water Resources Association (JAWRA) 46(2):429-442. DOI: 10.1111/j.1752-1688.2009.00412.x Abstract: We compared the National Land Cover Database (NLCD) 2001 land cover, impervious, and canopy data products to land cover data derived from 0.6-m resolution three-band digital imagery and ancillary data. We conducted this comparison at the 1 km², 9 km², and gauged watershed scales within the Baltimore Ecosystem Study to determine the usefulness and limitations of the NLCD in heterogeneous urban to exurban environments for the determination of land-cover information for hydrological applications. Although the NLCD canopy and impervious data are significantly correlated with the high-resolution land-cover dataset, both layers exhibit bias at <10 and >70% cover. The ratio of total impervious area and connected impervious area differs along the range of percent imperviousness – at low percent imperviousness, the NLCD is a better predictor of pavement alone, whereas at higher percent imperviousness, buildings and pavement together more resemble NLCD impervious estimates. The land-cover composition and range for each NLCD urban land category (developed open space, low-intensity, medium-intensity, and high-intensity developed) is more variable in areas of low-intensity development. Fine-vegetation land-cover/lawn area is incorporated in a large number of land use categories with no ability to extract this land cover from the NLCD. These findings reveal that the NLCD may yield important biases in urban, suburban, and exurban hydrologic analyses where land cover is characterized by fine-scale spatial heterogeneity.     

Managing the Three-Rivers Headwater Region, China: From Ecological Engineering to Social Engineering

The three-rivers headwater region (THRHR) of Qinghai province, China plays a key role as source of fresh water and ecosystem services for central and eastern China. Global warming and human activities in the THRHR have threatened the ecosystem since the 1980s. Therefore, the Chinese government has included managing of the THRHR in the national strategy since 2003. The State Integrated Test and Demonstration Region of the THRHR highlights the connection with social engineering (focus on improving people’s livelihood and well-being) in managing nature reserves. Based on this program, this perspective attempts a holistic analysis of the strategic role of the THRHR, requirements for change, indices of change, and approaches to change. Long-term success of managing nature reserves requires effective combination of ecological conservation, economic development, and social progress. Thus, the philosophy of social engineering should be employed as a strategy to manage the THRHR.

香港典型地质遗迹资源与地质公园建设

香港素以金融、商业贸易中心闻名于世界,但香港境内所发育的曲折有致的岩石海岸、幽远宁静的海滩、巍峨多姿的群山、造型奇异的岛礁,弥足珍贵的自然生态和地质遗迹资源却鲜为人知。本文在对香港地质概况进行简单介绍的基础上,对香港地质遗迹资源进行系统分类和对比分析,指出西贡万宜水库至果洲群岛方圆近150 km2范围内发育的十分典型、极具规模的六方柱状节理构造景观是世界上同类岩石中罕见的地质现象,其分布面积大,露头完整,具有稀缺性、独特性和典型性,最后对香港国家地质公园一个公园,两个园区,八个景区的空间结构及每个园区的主要地质遗迹资源进行了系统归纳总结。香港国家地质公园的建立很好的起到了保育地质多样性的首要目标,同时很好地推动了香港的地质教育和科普发展。

Knowing and Doing: Research Leading to Action in the Conservation of Forest Genetic Diversity of Patagonian Temperate Forests

Abstract:  Researchers dealing with conservation subjects usually do not put the results of their work into practice, even when the primary purpose of their research is the preservation of biodiversity. In the South American temperate forests we identified an area with the highest genetic diversity in Argentina of Nothofagus nervosa, one of the most relevant southern beech species. Based on the information of our scientific study and our recommendations, the authorities of Lanin National Park changed the protection status of this area to avoid logging. The new forestry management plans include consideration of "high genetic diversity" in decisions on where logging will be allowed. Results of our initial genetic study induced the analysis of biodiversity at the species and ecosystems levels, which yielded results similar to our genetic studies. A strong connection among researchers and managers from the onset of our study and the awareness of the former about the importance of the implementation of the research work were key to bridging the gap between conservation research and conservation practice.
