Selection of salt-tolerant plants for high-salinity wastewater treatment by constructed wetlands [PDF]
, 2017 人工湿地作为一种新兴污水处理工艺,具有高效、低成本等优点,但因缺乏能够在高盐环境中生存的湿地植物,因此应用于高盐污水处理还存在诸多难题.基于对我; 国南方海岸及海岛的大量野外调查及文献调研,依据生理指标、形态指标、经济成本和应用潜力等,筛选出耐盐、耐水湿、耐污、净化能力强、生长快、生物量大、; 栽培简单、分布广泛并具有景观效果的南方滨海耐盐植物23种,进一步对每一种植物的耐盐能力进行分级,其中耐盐能力最强的种类为扁秆荆三棱(Bolbos; choenus planiculmis)、海雀稗 ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Shuitu Baochi Xuebao, 2004 采用GIS技术与层次分析法相结合,对湖南省生态环境质量状况进行了综合评价。通过建立综合评价的指标体系和基本评价单元,应用层次分析法确定各评价指标的权重,再运用GIS技术,计算评价单元的质量指数和分指数,自动生成湖南省生态环境综合评价等级图,并从自然环境、灾害状况、环境污染和社会经济状况方面进行了空间分界规律分析。结果表明,社会经济与自然环境状况的空间格局大体吻合,湖南省生态环境质量基本上由东向西逐渐降低,但局部地区有差异。说明自然条件对湖南省生态环境质量的空间分异起主要作用,但灾害状况 ...

耦合生态系统服务供求关系的生态安全格局动态分析——以闽三角城市群为例 [PDF]
, 2018 实现分区管理是缓解城市群生态安全空间差异的有利途径。基于供求理论构建了生态系统服务供求关系动态模型框架,并利用供给与需求的象限区划表征闽三角城市群生态安全格局;在不同的尺度变换上,运用价值单量修正模型、INVEST生境质量模型、景观指数模型、生态韧性模型、熵权法等方法综合测度城市群生态系统服务供求水平,实现生态安全格局的分区化;引入环境库兹涅茨曲线理论解析区域生态安全格局现状和成因;数据分析借助Arc GIS可视化表示。研究发现:(1)闽三角城市群存在50%区域属于生态安全高供给失衡区,其中70 ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological communities are stressed by rapid and complex anthropogenic changes, threatening the persistence of biotic interactions and ecosystem functioning. Plant–pollinator communities, for instance, undergo structural transformations as a result of land‐use change ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...
