On the normative roles of biodiversity and naturalness in conservation
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Nature is an opaque concept. Consequently, the term biodiversity conservation has replaced nature conservation in most conservation contexts. We review the conceptual indeterminacies that plague the terms nature and natural but then show that comparable difficulties plague biodiversity.

Integrative Conservation, Volume 4, Issue 3, Page 491-502, September 2025.The impact of various restoration strategies on biodiversity and biomass in degraded savannas was evaluated across different elevation gradients. Natural regeneration co‐benefits the increasing in biodiversity and biomass in savannas, while active restoration exhibits altitude‐dependent efficacy and lower biomass accumulation capacity.

基于GIS的干热河谷植被恢复分区研究——以攀枝花城市视野区为例
Shuitu Baochi Xuebao, 2003 以攀枝花视野区为例,研究了基于GIS的干热河谷区植被恢复适宜性评价及分区方法.在干热河谷植被恢复适宜性评价及分区中,主要考虑对植被类型及植物生长影响较大的海拔高度、坡向、坡度、岩土类型、土层厚度等因素,并采用专家评分法给各影响因子权重和适宜性评价赋值.经过GIS的数据处理、空间分析、模型建立及运算,得到植被恢复适应性评价图,再经过分类、合并,将攀枝花市视野区划分为适宜区、较适宜区、较不适宜区、不适宜区、极不适宜区,得到植被恢复分区图.

Integrative Conservation, Volume 4, Issue 3, Page 476-490, September 2025.The leaf functional traits of angiosperms and gymnosperms in mountain ecosystems significantly influence phyllosphere fungal diversity. These traits are critical for understanding fungal stress resistance and elevational adaptation, which aids in predicting plant responses to climate change.

Integrative Conservation, Volume 4, Issue 3, Page 393-404, September 2025.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.

, 2007 2004年12月-2005年5月武汉市月湖水生植被重建过程中,对浮游植物进行逐月调查.结果表明,在营养盐浓度较高的条件下,浮游植物仍保持较低的生物量和密度,浮游植物的生长与温度保持一定的相关性,但与湖水营养盐浓度并不存在相关关系.菹草和伊乐藻能使水体的透明度保持较高的状态.浮游植物主要由隐藻和硅藻组成,能形成水华的一些常见种类并未随温度升高而出现,可能与这两种沉水植物的存在改变了浮游植物的群落结构有关.因此 ...

Shuitu Baochi Xuebao, 2018 通过对山西右玉贾家窑阳坡退耕还林约20年后的4种植被恢复模式（自然恢复草地、油松林、柠条灌丛和油松—柠条林）土壤水分、理化性质、径流量和侵蚀量的测定，探讨了不同植被恢复模式的水土保持效应。结果表明：（1）4种植被恢复模式0—100 cm土层土壤平均含水量无显著差异，油松林和自然恢复草地的土壤容重高于油松—柠条林和柠条灌丛，土壤总孔隙度的变化趋势与容重相反；（2）4种植被恢复模式0—20 cm土层土壤粒度组成、pH、有机质、铵态氮和速效磷无显著差异，硝态氮和速效钾差异明显 ...
