陕甘宁革命老区是黄土高原和黄河中上游的重点生态治理区,作为重要的生态屏障区,其生态治理意义重大。以陕甘宁革命老区为研究区域,基于改进的生态系统服务价值(ecosystem service value,ESV)当量因子法,利用地理探测器及地理加权回归(geographically weighted regression,GWR)模型,分析1995—2018年各县ESV时空变化特征、影响因素及各主导因素作用强度的空间分异特征。结果表明:(1)1995—2018年,陕甘宁革命老区ESV呈先下降后上升的特征 ...

Abstract Large old trees are important ecological entities in human settlements, providing cultural values and ecological services that are threatened by current and future changes in global climate, land use and disturbance regimes. Some studies suggest incorporating social and cultural significance into the conservation of large old trees.

Restoration of monoculture in protected and marginal areas can be organized into two phases (1) identification and prioritization of restoration sites based on remote sensing or field survey then assessing degradation level, and (2) implementation of appropriate restoration interventions.

We studied the challenges in human‐wildlife coexistence in Abohar wildlife sanctuary and the surrounding landscape in Punjab, India. We found that the local people's unique intrinsic motivation for conservation and the traditional approaches to conservation are no longer sufficient.

黄土高原在环境脆弱与经济发展低下的双重胁迫下,如何探索既适合环境保护又适应当地经济发展需求的战略对策至关重要。以黄土高原生态系统服务价值分析为基础,提出了该地区以农户单元、流域单元和区域尺度的生态系统服务恢复与重建对策。研究表明,尽管长期以来被人们所忽视,在生态环境脆弱区的生态系统服务价值依然是客观存在的,但是这些服务功能远不足以维持系统的自我循环,导致生态环境恶化趋势日趋严重。为此,必须科学分析该地区生态系统服务的现状与不足,并采取科学合理可行的生态系统恢复对策 ...

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition
Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.

The need for carbon finance schemes to tackle overexploitation of tropical forest wildlife
Abstract Defaunation of tropical forests, particularly from unsustainable hunting, has diminished populations of key seed dispersers for many tree species, driving shifts in forest community composition toward small‐fruited or wind‐dispersed trees with low wood density. Such shifts can reduce aboveground biomass, prompting calls for overexploitation to

在"双碳"目标和保护生态环境的双重约束下,研究土地利用变化引起的碳排放与生态系统服务价值之间的交互关系对促进碳中和目标实现与区域高质量发展具有重要意义。选取长株潭城市群主城区为研究对象,以2000-2020年5期土地利用、能源消耗和社会经济等数据为基础,综合运用网格分析法和双变量空间自相关模型探索土地利用碳排放与生态系统服务价值的时空演变特征及交互作用规律。结果表明:(1)2000-2020年各土地利用类型间发生不同程度的转移,其中,耕地与林地分别减少392.77,268.10 km2 ...

Servicesheds connect people to the landscapes upon which they depend
Abstract Ecosystem services (ES) are benefits people receive from nature. To sustain these benefits, we need to spatially connect communities benefitting from specific ES with landscape features that generate the ES. A variety of process‐based models support ES assessments by estimating the biophysical supply of ES that comes from landscapes.
