The value of small size: loss of forest patches and ecological thresholds in southern Madagascar.

Many services generated by forest ecosystems provide essential support for human well-being. However, the vulnerability of these services to environmental change such as forest fragmentation are still poorly understood. We present spatial modeling of the generation of ecosystem services in a human-dominated landscape where forest habitat patches, protected by local taboos, are located in a matrix of cultivated land in southern Madagascar. Two ecosystem services dependent on the forest habitats were addressed: (1) crop pollination services by wild and semidomesticated bees (Apoidea), essential for local crop production of, for example, beans, and (2) seed dispersal services based on the presence of ring-tailed lemurs (Lemur catta). We studied the vulnerability of these ecosystem services to a plausible scenario of successive destruction of the smallest habitat patches. Our results indicate that, in spite of the fragmented nature of the landscape, the fraction of the landscape presently covered by both crop pollination and seed dispersal services is surprisingly high. It seems that the taboo system, though indirectly and unintentionally, contributes to upholding the generation of these services by protecting the forest patches. Both services are, however, predicted to be very vulnerable to the successive removal of small patches. For crop pollination, the rate of decrease in cover was significant even when only the smallest habitat patches were removed. The capacity for seed dispersal across the landscape displayed several thresholds with habitat patch removal. Our results suggest that, in order to maintain capacity for seed dispersal across the landscape and crop pollination cover in southern Androy, the geographical location of the remaining forest patches is more crucial than their size. We argue that in heavily fragmented production landscapes, small forest patches should increasingly be viewed as essential for maintaining ecosystem services, such as agricultural production, and also should be considered in the ongoing process of tripling the area of protected habitats in Madagascar.     

乙醇废水的超临界水氧化处理工艺研究

研究了以超临界水氧化法（SCWO）处理乙醇废水的工艺过程，实验表明，一氧化碳和二氧化碳分别是反应中间产物和最终，550℃，25MPa,停留时间大于15s时，SCWO能将乙醇完全氧化为二氧化碳，达到稳彻底处理的目的，随停留时间增大，湿度升高，乙醇的去除率增大，而压力和氧气浓度的变化对过程没有显著影响。

城市空气质量监测网络评估方法

通过研究借鉴多个国家/城市的研究实践,提出了城市空气治理监测网络（UAAMNA）评估管理的方法,包括评估思路与流程,评估关键指标,针对不同污染物的评估方法等.以沈阳市及周边6个城市共46个国控监测站点的监测网络为背景,基于2013~2018年日尺度空气质量数据,考虑监测成本,对沈阳市PM_2.5监测网络进行评估,结果表明,沈河区增加1个最高浓度站点,大东区增加1个高人口密度区站点,皇姑区增加1个跨界传输点;在沈阳-铁岭,沈阳-本溪,沈阳-辽阳方向增设跨区域站点.未来建立空气质量监测网络定期评估制度、加强跨区域边界站点布设、实施区分监测点位类型评估、区分污染物类型评估是UAAMN的发展方向.     

Catalytic ozonation treatment of papermaking wastewater by Ag-doped NiFe2O4: Performance and mechanism

The catalytic ozonation treatment of secondary biochemical effluent for papermaking wastewater by Ag-doped nickel ferrite was investigated. Ag-doped catalysts prepared by sol-gel method were characterized, illustrating that Ag entirely entered the crystalline of NiFe₂O₄ and changed the surface properties. The addition of catalyst enhanced the removal efficiency of chemical oxygen demand and total organic carbon. The results of gas chromatography-mass spectrometer, ultraviolet light absorbance at 254 nm and three-dimensional fluorescence excitation-emission matrix suggested that aromatic compounds were efficiently degraded and toxic substances, such as dibutyl phthalate. In addition, the radical scavenging experiments confirmed the hydroxyl radicals acted as the main reactive oxygen species and the surface properties of catalysts played an important role in the reaction. Overall, this work validated potential applications of Ag-doped NiFe₂O₄ catalyzed ozonation process of biologically recalcitrant wastewater.     

基于能值分析的西安市三个发展核心区可持续性研究

本文基于能值分析和城市复合生态系统的理论与方法,从生态环境系统及社会经济系统两方面,对西安市灞桥区、雁塔区和未央区2014年的基础数据进行计算整理,通过分析三个发展核心区的能值利用效率,排除废物流能值对系统的消极影响,构建基于能值利用效率(EUE)的系统可持续发展程度指标(EUSDI),确切评估三个区城市复合生态系统的可持续发展能力。结果表明:灞桥区可持续发展指数为0.1545,雁塔区为0.0906,未央区为0.0579。灞桥区能值利用效率为较高的94.81%,可更新资源较为丰富,但较为依赖不可更新资源与外部输入产品;雁塔区能值利用效率为较低的86.57%,社会经济发展程度较高,但可更新资源较贫乏,人口过于集中对环境造成很大压力;未央区能值利用率为较低的84.93%,该区可更新资源较少,工业生产消耗大量不可更新资源,"三废"的排放也严重影响了该区的生态环境。
