Ecohydrological characteristics of biocrusts explain divergent responses of biocrusts and grasses to rainfall reduction

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2843-2860, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Drylands are mainly structured by both vascular plants and biological soil crusts (biocrusts), the latter often regarded as a self‐organizing component of these ecosystems.

基于生态压力指数的新疆生态安全时空动态分析/Spatiotemporal Analysis of Ecological Security in Xinjiang based on Ecological Pressure Index[J]

open access: yes, 2012
通过计算2000—2007年新疆各地州(市)的生态足迹和生物承载力,选取生态压力指数(EPI)构建区域生态安全评价模型,对不同地区的生态安全状况进行了评价并分析其时空动态变化。结果表明:①2000—2007年新疆各地州(市)人均生态足迹均呈增长趋势,而生物承载力总体上呈减少趋势。②西部大开发战略实施以来,新疆经历了由生态安全向生态不安全演变的过程;各地州(市)生态不安全程度逐年增加,且增加幅度不等。③新疆生态安全程度的空间分布呈现一定的规律性,北部地区〉中部地区〉东、西部地区 ...

Multi‐gradient warming reshapes functional traits and adaptive responses of alpine meadow plants

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2889-2905, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant functional traits in alpine meadows are critical indicators of ecosystem responses to climate warming, yet dynamic changes in trait networks across warming gradients and their consequences for community functions remain poorly understood.

Phenology drives asymmetric responses of ecosystem productivity stability to warming and cooling

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2959-2971, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem productivity stability is a key indicator of ecosystem functioning under climate change, but the role of cooling periods in increasingly variable climates remains poorly resolved.

山东省沿海区域景观生态风险评价

open access: yes, 2014
以山东省沿海区域2000、2005、2010年景观格局数据以及Spatial-Markov模型模拟2020、2030年景观格局,基于景观结构指数计算5个时期的景观生态风险,分析景观生态风险的时空特征,为生态风险管理决策提供科学依据。结果表明:2000—2010年,低生态风险小区面积比例不断下降,中生态风险小区面积比例持续上升,较高生态风险小区面积比例则波动上升,在目前趋势发展情景下,2020—2030年风险小区风险等级由低到高转化强度比2000—2010年加大,高生态风险小区比例快速上升 ...

Ten rules for using evidence to guide ecosystem restoration

open access: yesJournal of Applied Ecology, Volume 63, Issue 9, September 2026.
These 10 rules provide a guidance framework to put into action the best available evidence, ensuring that restoration benefits people and nature. We highlight the importance of knowledge brokering systems in this process, effectively informed and empowered to fulfil their emerging role across existing institutions and new ones dedicated to Science ...

塔里木河中下游退耕还林还草综合生态效益评价

open access: yes, 2004
本文以恢复生态学理论与实践为指导,以植被恢复与重建和水资源可持续利用为目的,选择了11项适合于荒漠内陆河流域自然环境的评价指标,建立了塔里木河中下游退耕还林还草综合生态效益评价指标体系和数学模型,用层次分析法(P),确定了各项指标权重。以现有的人工林草植被代替未来不同的退耕还林还草模式(空间换时间方法),对塔里木河中下游退耕还林还草综合生态工程以水为主线的生态效益进行了定量评价,计算了流域内各种退耕还林还草模式的综合生态效益指数,并与农田生态系统进行了效益比较。主要研究结果如下:1 ...

野生动物相关专业学生生态道德现状及教育对策

open access: yes野生动物学报, 2017
采用分层随机抽样的方法对全国开设野生动物相关专业的6所高校的600名学生进行问卷调查。分析结果显示,野生动物相关专业学生生态道德素质总体处于“良好”水平,其中生态道德知识水平的平均得分为(3.60±0.50),生态道德意识为(4.15±0.62),学生生态道德行为平均分相对偏低,为(3.47±0.50); 但学生的生态道德教育需求未能得到很好地满足,教育状况处于“一般”水平(3.39±0.38),表明学生的生态道德教育还需进一步加强。生态道德素质与生态道德教育水平与学生的性别、年级有关。针对调查结果 ...
