放牧家畜与食草野生动物争草(畜兽冲突)是人兽冲突在草原放牧业中的具体体现,其涉及面广,对牧民生计影响明显。畜兽冲突强度研究对完善野生动物损害补偿制度、促进人与自然和谐共生具有重要意义。论文通过地面调查与模型模拟,考虑草地... 放牧家畜与食草野生动物争草(畜兽冲突)是人兽冲突在草原放牧业中的具体体现,其涉及面广,对牧民生计影响明显。畜兽冲突强度研究对完善野生动物损害补偿制度、促进人与自然和谐共生具有重要意义。论文通过地面调查与模型模拟,考虑草地牧草产量、家畜存栏量和食草野生动物种群数量,提出了放牧家畜与食草野生动物争草冲突强度量化方法,评价了三江源国家公园玛多县牧草地畜兽争草强度。结果表明:(1)据2022年样线调查和随机森林模型估计,玛多县藏野驴(Equus kiang)、藏原羚(Procapra picticaudata)种群密度分别为0.2157头/km^(2)、0.1655只/km^(2),种群数量分别为5307头、4073只,折合23264羊单位(SU),2018年末各类家畜存栏量34.2万SU,畜兽争草相对强度为1/14.7。(2)玛多县高寒草甸、高寒草原的可食牧草产量分别为118.7 g/m^(2)、88.3 g/m^(2),可承载密度分别为0.2710 SU/hm^(2)、0.1532 SU/hm^(2),理论承载力52.85万SU。家畜承载率、食草野生动物承载率、家畜+食草野生动物承载率分别为64.7%、4.4%和69.1%。(3)国家公园内的乡镇,草地承载力盈余,家畜承载率低、野生动物承载率高,但畜兽争草相对强度较大,建议完善移民搬迁、野生动物损害补偿制度,强化国家公园体制建设;国家公园外的乡镇,草地超载严重,家畜承载率高,畜兽争草强度不高,建议减畜增效、绿色发展。 展开更多

Human-wildlife conflict(HWC) is a global conservation issue of increasing concern,and understanding the factors driving conflict is crucial for preventing or mitigating it. In many parts of China,large human populations and increasing development has led to an escalation in HWC with both carnivore and prey species. In this paper we assess herder attitudes toward blue sheep(Pseudaois nayaur,Hodgson,1833),white lipped deer(Carvus albirostris,Przewalski,1883),red deer(Cervus elaphus,Linnaeus,1758),and marmot(Marmota himalayana Hodgson,1841) through interview-based surveys conducted in 46 households across 8 villages in Qilianshan National Nature Reserve,Gansu,China. We also examine the perceived impact of three ecological-restoration policies(anti-grazing,sustainable grazing,and grass-planting policies) on livelihoods,and how this affects attitudes toward wildlife. Herders reported neutral attitudes toward wildlife species in general,but reported negative attitudes towards blue sheep. Mixed-effects modeling revealed that herder attitudes toward the target species varied significantly across villages,but other socioeconomic variables had limited explanatory power for attitudes. Furthermore,we found that while policy implementation was negatively perceived by herders,anti-grazing policy implementation and total policy implementation were positively correlated with positive attitudes toward wildlife,highlighting a potential gap between perceived threats and actual threats. Finally,we show that the leading cause of reported livestock death is preventable disease,alleviation of which may help improve attitudes toward wildlife. 展开更多
