Retaining natural vegetation to safeguard biodiversity and humanity
Conservation Biology, Volume 37, Issue 3, June 2023., 2023 Abstract Global efforts to deliver internationally agreed goals to reduce carbon emissions, halt biodiversity loss, and retain essential ecosystem services have been poorly integrated. These goals rely in part on preserving natural (e.g., native, largely unmodified) and seminatural (e.g., low intensity or sustainable human use) forests, woodlands, and ...

Conservation Biology, Volume 34, Issue 3, Page 654-665, June 2020., 2020 Abstract The Convention on Biological Diversity's (CBD) strategic plan will expire in 2020, but biodiversity loss is ongoing. Scientists call for more ambitious targets in the next agreement. The nature‐needs‐half movement, for example, has advocated conserving half of Earth to solve the biodiversity crisis, which has been translated to protecting 50 ...

Shuitu Baochi Xuebao, 2003 针对辽西水土保持林中油松纯林集中成片、松毛虫猖獗的树种结构现状,采用了廊道式、斑块式、林中空地、林中沟壑、封山育林、飞播造林和营造混交林7种调整方法,对油松纯林进行了树种结构调整试验.根据不同树种水分利用、生长情况等综合指标,筛选出了14个适合水土保持林树种结构调整的树种.通过不同调整类型的对比试验及适地适树原则,划分并营建了适合辽西水土保持林树种结构调整的3种调整模式.试验结果表明,水土保持林中的油松纯林经树种结构调整后,林分中松毛虫不再大发生,水土保持功能有了明显提高,林木生长加快 ...

庐山杉木林与黄山松林的土壤层水源涵养能力和土壤侵蚀敏感性探究
Shuitu Baochi Xuebao, 2022 森林的水土保持效益包含水源涵养能力和土壤的侵蚀敏感性,为探讨基于坡面尺度林分因子对水土流失的影响,进一步揭示森林植被的水土保持效益机制,采用环刀法、EPIC模型等分别计算黄山松林、杉木林的水源涵养能力和土壤侵蚀因子。结果表明:(1)黄山松林的土壤容重在垂直剖面无明显差异,变化范围为0.66~1.10 g/cm3;杉木林的容重(0.92~1.21 g/cm3)则呈现中下层(40-80 cm)大于中上层(0-40 cm)。黄山松林上层(0-20 cm)土壤的最大持水量极显著大于杉木林。土壤的毛管持水量 ...

Shuitu Baochi Xuebao, 2001 水土保持措施的实施可有效地控制土壤侵蚀 ,不同的水土保持措施存在不同的水土保持效益值。利用北京密云石匣共 2 0个坡面径流试验小区的野外观测资料 ,分析得出了北京石匣小流域不同水土保持措施下的水土保持效益值 ,其中免耕 (玉米 )为 0 .2 80 ,梯田 (玉米 )为 0 .142 ,人工草地为 0 .0 6 3,荒草地为 0 .0 45 ,水平条林地为0 .0 2 5 ,鱼鳞坑林地为 0 .0 19。人工草地、荒草地、水平条林地和鱼鳞坑林地有显著的水土保持效益 ,但它们之间的水土保持效益并无显著差别。

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.

Integrative Conservation, Volume 4, Issue 3, Page 362-380, September 2025.Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.

Shuitu Baochi Xuebao, 2004 通过对15°红壤坡地11个利用模式10年土壤侵蚀研究,认为红壤坡地土地利用模式中林作系统水土保持效果优于农作系统。林作系统中水土保持效果以常绿阔叶林最好,次为混交林,毛竹林和针叶林。农作系统中顺坡植物篱种植、等高梯化种植、顺坡水平沟种植水土保持效果较好。研究认为红壤坡地土地利用模式应以林作为主,尽可能发展高效的经济林。而如发展农业种植,则以顺坡植物篱种植模式最佳,次为等高梯化种植模式。

Integrative Conservation, Volume 4, Issue 3, Page 503-513, September 2025.Fire occurrence increased with proximity to roads and villages, indicating that human access and activity are major drivers of fire risk. We analyzed spatial patterns of fire in relation to human settlements. Our findings highlight the need for fire management strategies that consider accessibility and human presence in conservation planning.
