“…One of the species that lives in this kind of ecosystem is guanaco ( Lama guanicoe ; Müller 1776 ), which is regarded as one of the most ecologically important and abundant native ungulate of the arid cold-temperate regions of South America, inhabiting diverse habitats from sea level to over 4,000 m ( Franklin 1982 ; Wheeler 1995 ). On the western slopes of the Andes, guanacos are widely distributed from northern Peru to Tierra del Fuego and Navarino Islands in Chile ( Iranzo et al 2022 ). To the east, they extend southward from the Bolivian and Paraguayan Chaco, and eastward across the pampas to the Atlantic, throughout most of Argentina ( Torres 1985 ; González et al 2006 ).…”

“…Although the selective pressure that resulted in its ability to resprout has not been confirmed with absolute certainty, it likely developed in response to grazing from the native herbivore Lama guanicoe, or in response to wildfires further north in N. antarctica's range (Veblen et al, 1999). As N. antarctica is commonly found in the ecotone between forest and grassland, it has been subject historically to more consistent and intense grazing than other Nothofagus species from herbivores that move between grasslands and adjacent forests (Veblen and Lorenz, 1988;Iranzo et al, 2022). Despite adapting to this selective pressure, constant trampling and browsing by livestock (cattle, sheep, and horses) and native herbivores over many years can still deform or impede N. antarctica regeneration (Raffaele et al, 2011;Echevarría et al, 2014).…”

“…第 11 期 王守兴 等:基于草地承载力的畜兽冲突强度研究 的人猴冲突地区占国土面积的 15% [15] 。2021 年世 界自然基金会与联合国环境署(WWF/UNEP)发布 了 《共享未来--人与野生动物共存的必要性》 的 报告, 呼吁将人与野生动物共存纳入 《生物多样性 公约》目标进程与可持续发展目标框架, 以实现 2050 年人与自然和谐相处 [16] 。由此, 人兽冲突缓解 和共存成为学者和管理者共同关注的跨学科、 跨部 门的研究议题。迄今对食肉动物引起的冲突研究 较多, 对食草动物引起的冲突研究较少 [17] , 冲突强 度量化 [18] 、 尤其是畜兽冲突强度量化研究更少 [14] 。 野生动物损害补偿是国内外普遍采用的冲突缓解 制度 [19][20][21] , 而厘清畜兽冲突强度是实现食草野生动 物损害科学补偿的前提。 生态承载力是生态系统结构、 功能及空间格局 决定的对外部扰动的最大承受能力 [22] , 传统草地承 载力研究没有考虑野生动物的采食量 [23] , 当野生食 草动物数量增加时, 家畜与野生动物争草现象难以 避免 [14] 。Iranzo 等 [24] 研究了智利火地岛(Tierra del Fuego) 自 然 保 护 地 和 周 边 牧 场 的 南 美 野 生 羊 驼 (Lama guanicoe)的密度, 发现牧场的羊驼密度、 群 体比例、 种群规模大于保护地内部。在印度 Keibul Lamjao 国家公园的漂浮草甸中, Tuboi 等 [23] 根据牧 草 需 求 和 可 利 用 牧 草 量 估 计 野 生 坡 鹿 (Rucervus eldii eldii)、 猪鹿(Axis porcinus)的合理密度分别为 0.141 、 0.265 只/hm 2 , 可见, 在承载力研究中应该考 虑野生动物因素 [25] 。三江源国家公园黄河源园区 (位于玛多县)是中国高寒草甸生态系统大尺度保 护的典型区域。近 20 年来, 黄河源园区野生动物 种 群 数 量 恢 复 , 不 仅棕熊(Ursus arctos)、 狼(Canis lupus)等食肉动物伤害人畜的事件增多 [17] , 藏野驴 (Equus kiang)、 藏 原 羚 (Procapra picticaudata) 等 食 草野生动物与家畜争食也很常见 [7,26] 。但对食草野 生动物致害的监测、 预防、 定损等存在诸多短板 [27] , 这类冲突尚难以纳入野生动物损害补偿范围。因 此, 本文以玛多县为例, 基于承载力理论提出畜兽 争草强度量化方法, 以期为完善野生动物损害补偿 制度提供支撑。…”
