| 1 | 生态修复背景下园林园艺类博览会植物景观营建研究显示文摘在生态文明建设的大背景下,生态修复已经成为中国园林园艺类博览会的热点亮点,这对植物景观营建提出了新的要求和挑战。通过回顾我国综合性园林园艺类博览会在生态修复方面的探索,结合科学绿化的建设要求,提出生态修复背景下园林园艺类博览会中植物景观营建的目标需要综合生态、城市景观、城市事件的三重要求,遵循问题与目标导向相结合、人工修复和自然恢复相结合、景观塑造和群落营造相结合的工作要点。综合国内外相关植物景观营建实践,探讨在全园规划尺度、展园设计尺度和展后利用方面如何将生态修复和植物景观营建实践相结合,为今后园林园艺类博览会以及更大范围的风景园林生态修复实践提供参考。 | 赵茜瑶 唐予晨 李慧 | 2022 | 中国园林2022，38，6： | 3 |
| 2 | Novel ecosystems in ecological restoration and rehabilitation:Innovative planning or lowering the bar?显示文摘Stemming from a special symposium at the 2012 inaugural meeting of the Society for Ecological Restoration Australasia in Perth,Western Australia,this special issue editorial addresses novel ecosystems in ecological restoration and the inherent challenges of maintaining the highest standards of environmental stewardship and biological conservation in the face of increasing urbanization,agricultural expansion,and industrialization.Echoing others,we(the Guest Editors)view novel ecosystems as offering opportunities for conservation and restoration in the coming years and a pragmatic recognition that it may not always be possible,or desirable,to overcome adverse consequences of environmental degradation to reinstate historical systems.Being mindful of hubris and taking into account difficulties with identification,novel ecosystems may be viewed as a temporary or interim stage on the way towards the evolution of other future ecosystems able to supply a variety of ecosystem services,while attempting to maintain and enhance biodiversity,function and resilience.Here,a concise summary of contributions to the special issue and their significance to the field of restoration ecology is provided noting that authors were tasked to answer whether novel ecosystems are innovative planning or lowering the bar in ecological restoration.Core themes shared by the manuscripts are elucidated leading to guiding principles and,more importantly,an assessment of how and why restoration priorities are changing in the 21^(st)century. | Michael P Perring Patrick Audet David Lamb | 2014 | Ecological Processes2014，3，1： | 1 |
| 3 | Phosphate uptake and translocation in a tropical Canna-based constructed wetland显示文摘Introduction:Considering the problem of eutrophication of the water bodies,phosphate removal from water has emerged as a research of topical interest.The present study aims to investigate the efficacy of Canna lily-based constructed wetland to remove phosphate from wastewater.The translocation of phosphate in plant tissue and its biochemical transformation in sediments is also studied to understand its accumulation and recirculation within the system.Results:The removal of phosphate stabilized at around 50%in the present study and plant uptake was found to be the major removal mechanism.Average removal was 167 mg/m2 day for total phosphate and 84 mg/m2 day for available phosphate for an initial loading rate of 200 mg/m2 day and 85 mg/m2 day,respectively,at a HRT of 24 h.Most of the phosphate concentrated in above ground tissue of plant and its relative accumulation was maximum in flowers.Fractionation of phosphate in sediments confirmed removal by sediments with an accumulation of apatite phosphate(Ca and Mg bound),but release of non-apatite form(Fe and Al bound).Conclusion:The study concludes that Canna-based constructed wetland can be an effective tool for phosphate removal from wastewater and sediments particularly under tropical conditions.Regular harvesting of above ground tissue of Canna can result in nutrient export from the system,whereas autochthonous addition may result in recirculation. | Anil Kumar Haritash Sarbari Dutta Ashish Sharma | 2017 | Ecological Processes2017，6，1： | 1 |
