Shuitu Baochi Xuebao, 2023 对人类活动量化中考虑区域生态条件的差异,基于季节尺度,利用潜在NPP与实际NPP计算HAII,选取植被类型、高程、坡度等7个自然因子与HAII进行空间分异探测分析,以更细的季节尺度揭示多因子的影响规律。结果表明:在描述青藏高原人类活动对植被NPP的空间分异影响方面,HAII的解释力与显著性均优于人类活动值,其解释力最高为0.714。在多因子影响植被NPP空间分异方面,自然与人为因子均表现出明显季节差异,夏季人类活动解释力最高,春、秋季减弱,冬季则主要受自然因子影响。其中,坡度、温度 ...

Integrative Conservation, EarlyView.We collated detections of the sun bear from new and previously published camera trap studies across its range. We then analysed these detections at two different spatial scales to assess the habitat associations and diel activity of this species. We found that the sun bear is tolerant to moderate habitat disturbances. ABSTRACT Degraded tropical forests,

Integrative Conservation, EarlyView.This study investigates distribution patterns of Galliforms in the Indian Himalayas, focusing on factors influencing their occurrence, regions of high diversity and endemism, and their overlap with protected areas. Our study highlights the need for assemblage‐level conservation strategies in high Himalaya which primarily relies on snow leopard‐focused ...

Impacts of Human Development on Wildlife Use of Corridors in Botswana 人类开发对博茨瓦纳野生动物廊道利用的影响
Integrative Conservation, EarlyView.This study examined the effect of landscape‐scale human impact on wildlife in Botswana. We examined how species use wildlife corridors in two different human‐dominated landscapes. We identified differences in temporal overlap between wildlife and humans across both landscapes, which is fundamental to consider in both current and future conservation ...

Integrative Conservation, EarlyView.Our research allows us to understand the predictors of extinction risk in traditional Chinese medicinal (TCM) plant species with known threat status, and incorporate this knowledge to predict other TCM plants with unknown conservation status in China so as to improve the overall effectiveness of conservation strategies.

Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau
People and Nature, EarlyView.Abstract The conflict between livestock husbandry and large carnivore conservation presents significant challenges in grassland ecosystems worldwide. Achieving sustainable coexistence among herders, livestock and large carnivores requires reconciling diverse perspectives and interests through equitable, inclusive and fair processes that address both ...

Shuitu Baochi Xuebao, 2002 荒漠绿州景观格局是不同类型、不同大小、不同形状和不同开发程度的地块（生态系统）在空间上构成的镶嵌体。景观镶嵌结构的差异反映出不同的功能，通过计算一些景观指数，对荒绿洲景观格局作出定量分析。人类活动强烈的景观要素或纯粹的人工景观中，表征复杂的景观指数往往高于人类活动较轻的景观要素，而表征稳定性的指数正好相反；处在干旱内陆荒漠中的绿洲景观，其抵抗外来干扰的能力低，恢复力弱，人类不合理的活动极易破坏其稳定状态，从而导致荒漠化发生。

Shuitu Baochi Xuebao, 2021 黄河流域在我国具有重要的战略地位，是我国重要的生态屏障，定量化评估气候变化和人类活动对黄河流域植被变化影响，对政府管理决策具有重要意义。以黄河流域为研究区，分析1982—2019年归一化植被指数（normalized difference vegetation index，NDVI）时空动态变化，定量计算气候变化及人类活动对NDVI变化的贡献度，并对NDVI变化影响因素进行分区制图；在此基础上，讨论生态建设工程对植被变化的影响情况，并评估其成效。结果表明：（1）1982 ...

Conservation Biology, EarlyView.Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

Shuitu Baochi Xuebao, 2000 考虑渭河水沙变化特性，根据水量平衡原理及产沙机制，应用天然时期的气象、水文资料建立了渭河产流产沙模型；采用水文模拟途径外延了人类活动影响期间的天然径流、泥沙过程，进而分析了渭河变化原因。结果表明：1970－1995年，渭河华县站平均径流、泥沙量较前期分别减少25.9亿m^3和1.11亿t，其中58.3%和55.7％是由人类活动影响所致，人类活动是渭河近年来水沙减少的主要原因。
