黄河流域经济带生态环境绩效评估及其提升路径

open access: yesShuitu Baochi Xuebao, 2023
黄河流域经济带是我国北方重要的经济走廊,科学评估黄河流域经济带生态环境绩效水平,提高黄河流域沿线9省生态环境质量是实现黄河流域经济带的高质量发展重要举措之一。运用生态环境质量评估、生态效率评估等研究方法,开展2012—2017年的生态环境质量、生态效率和绿色全要素生产率评估。结果表明:黄河流域经济带生态环境绩效水平总体呈现由较低水平不断提升的趋势;黄河沿线九省在生态环境质量和生态效率系统层中有明显差异,生态环境质量系统层中,上游地区的最优;生态效率系统层中,中下游地区的生态效率最优且稳定 ...

Study on coordinated development of environmental quality and land use degree based on remote sensing ecological index: A case study of Zhejiang province(基于遥感生态指数的土地利用程度与环境质量协调发展研究——以浙江省为例)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2023
将遥感生态指数应用于土地利用程度与生态环境质量协调研究,结合耦合协调度模型和空间自相关分析,研究了2008,2013,2018年浙江省89个区县的土地利用程度与生态环境质量协调发展时空特征,结果表明:(1)在空间尺度上,浙江省土地利用程度呈东高西低、北高南低的分布态势,各区县发展差距较大。在时间尺度上,各区县土地利用程度均有不同程度的提高,东高西低的趋势越发显著。(2)浙江省由于自然地理条件优越,生态环境质量总体保持较高水平,十年来生态文明建设取得了较大成果。(3)结合土地利用程度与生态环境质量评价结果,

耦合InVEST-PLUS模型的榆林市生境质量

open access: yesShuitu Baochi Xuebao, 2023
生境质量是衡量一个地区生态环境优劣的重要参考指标,土地利用变化研究可为区域生境质量时空动态演变特征评估提供科学依据。基于1980年、2000年、2018年土地利用数据,通过InVEST模型、PLUS模型、地理信息图谱法分析并预测榆林市土地利用变化情况,以此探究陕西省榆林市生境质量时空演变特征。结果表明:(1)榆林市景观基质主要由草地和耕地构成,林地和未利用地次之,水域和建设用地占比相对较少,退耕还林政策的实施、治沙工程的开展,以及建设用地的开发是土地利用变化的主要驱动因素。(2)从区域整体分析 ...

松花江流域哈尔滨段三生空间演变的生态环境效应及驱动因素分析

open access: yesShuitu Baochi Xuebao, 2022
探索三生空间演变的生态环境效应及驱动因素, 可为国土空间优化及生态环境保护的实施提供科学依据。以松花江流域哈尔滨段为例, 运用网格单元法, 结合生态环境质量指数、全局自相关模型、核密度函数等方法分析1986—2016年三生空间演变的生态环境效应时空分异特征, 并借助地理探测器模型揭示生态环境质量空间分异的驱动因素。结果表明: (1)1986—2016年研究区三生空间以生产空间为主, 其中农业生产空间和林业生态空间所占比重最大, 呈现生产空间和生态空间减少、生活空间增加的变化趋势; (2 ...

Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Elevated tropospheric ozone (O3) and nitrogen (N) deposition are concurrent atmospheric changes that strongly influence terrestrial carbon cycling, yet their combined effects on below‐ground decomposition remain poorly understood.

How Do I Measure up? Social Influence and L2 Motivation in the Algorithmic Age

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Comparative thinking is a fundamental human drive and a hallmark of contemporary life. For social action, such as the learning and use of additional languages, a target for appraisal (an L2 attribute) is evaluated in relation to a comparison standard (an appraiser's standpoint).

GIS支持下的湖南省生态环境质量综合评价

open access: yesShuitu 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 ...

Assessing Argument Quality in L2 Argumentative Writing: Integrating Argument Elements and Intellectual Standards

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Many existing rubrics for L2 argumentative writing prioritize form‐based linguistic accuracy and complexity while insufficiently addressing substantive argumentative rigor and effectiveness. This limitation is further complicated by cross‐cultural variation in rhetorical conventions and educational practices, which challenge the direct ...
