How percentage‐protected targets can support positive biodiversity outcomes
Conservation Biology, Volume 36, Issue 4, August 2022., 2022 Abstract Global targets for the percentage area of land protected, such as 30% by 2030, have gained increasing prominence, but both their scientific basis and likely effectiveness have been questioned. As with emissions‐reduction targets based on desired climate outcomes, percentage‐protected targets combine values and science by estimating the area ...

Conservation Biology, Volume 32, Issue 3, Page 672-684, June 2018., 2018 Abstract Land‐use change is the largest proximate threat to biodiversity yet remains one of the most complex to manage. In British Columbia (BC), where large mammals roam extensive tracts of intact habitat, continued land‐use development is of global concern.

Shuitu Baochi Xuebao, 2006 利用遥感影像数据进行生态系统净初级生产力、植被覆盖度等生态参数的采集，同时间接用于土壤保持量和水土保持价值的计算，结合修改过的USLE模型，对云南省生态系统2001，2002，2003年水土保持价值进行了测算，利用NPP对估算结果进行调整．以考虑生态系统类型、结构与质量差异对水土保持价值的影响。结果表明：云南省生态系统2001，2002，2003年土壤保持量分别为131798．92，117845．5，104176．71万t，对应的价值量分别为：1933．351，1707．579，1566．783亿元 ...

Shuitu Baochi Xuebao, 2022 土壤保持服务是生态系统服务中调节服务的一项重要内容,无定河流域水土流失严重,土壤保持服务成为其首要的生态系统服务。利用SWAT模型和GIS对无定河流域土壤保持服务供需平衡和空间流动路径进行探究分析,揭示无定河流域土壤保持服务供需空间匹配特征及其空间流转机制。结果表明:(1)无定河流域土壤保持服务供给量与需求量变化趋势具有较强的一致性,两者都呈波动上升的趋势,均与降水具有较强的相互对应关系。其中,2001年8月、2013年7月、2017年7月供给量及需求量达到了2000—2020年所有月份中的较大值 ...

Shuitu Baochi Xuebao, 2006 近几十年来，松嫩平原的生态环境严重恶化，荒漠化迅速发展，这与区域水土保持功能持续下降有关。本文应用生态学、经济学和生态环境科学等学科的有关理论，以TM／MODIS／DEM数据为基础，应用3S技术建立了松嫩平原水土保持价值的复合计算模型。计算表明，全区2001年水土保持总价值为662．63亿元，就单位面积的水土保持价值而言．林地最高，为173．59万元／km^2，草地次之，为70．42万元／km^2，耕地很低，为24．53万元／km^2，难利用地仅为2．89万元／km^2 ...

Shuitu Baochi Xuebao, 2005 农田生产系统不仅为人类提供了多种多样的农产品,同时,农作物对地表的覆盖以及各种水土保持措施的采用,使农田生产系统也发挥着重要的土壤保持功能。根据计算,我国农田生产系统每年保持土壤的数量为101.9×108t,其中,西南地区、黄土高原区和东北地区的农田土壤保持功能最为突出。采用市场价格法、机会成本法和影子工程法对农田保持土壤的价值进行评估,结果表明:我国农田每年保持土壤养分的价值为4408.50×108元/a,减少耕地废弃价值为164.09×108元/a,减轻淤积的价值为53.74×108元/a ...

Integrative Conservation, Volume 4, Issue 3, Page 345-353, September 2025.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.

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition
Antipode, Volume 57, Issue 3, Page 830-861, May 2025.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
Conservation Biology, Volume 39, Issue 1, February 2025.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
