| 1 | 藏东南三江并流核心区植被时空动态变化及其气候驱动力分析显示文摘植被生长状况及其分布对气候等影响因子的响应是当前生态学研究的热点之一。基于2000—2016年MODIS NDVI数据和气象数据,用Sen+Mann-Kendall等方法分析了藏东南三江并流核心区植被的时空变化及其与气候因子的关系。研究结果表明:(1)该区植被覆盖整体趋于稳定,呈缓慢增加趋势,不同植被类型覆盖空间异质性明显。(2)植被变化趋势结果显示植被覆盖变化以稳定不变和改善趋势为主,区域总体呈稳中向好态势。(3)相关分析表明植被NDVI增加主要与气候暖化有关,与降水量相关性较小。此外,人类活动对植被影响的双重性表现为:大多地区植被改善受生态工程和围栏禁牧政策影响,局部地区植被退化则与城镇化进程加快有关。研究结果揭示气温是影响植被格局的主要气候因子,了解影响植被变化及其驱动因素的空间变异性可为山地植被生态环境保护建设提供一定的科学依据。 | 王春雅 王金牛 崔霞 魏彦强 孙建 Niyati Naudiyal 杜文涛 陈庆涛 | 2021 | 地理研究2021，40，11： | 10 |
| 2 | 发育阶段和海拔对岷江源区陇蜀杜鹃小枝功能性状及生物量分配的影响显示文摘本研究分析了岷江源区卡卡山典型高山灌丛植物陇蜀杜鹃不同发育阶段(花芽期和开花期)及不同海拔(3600 m低海拔和3800 m高海拔)下功能小枝和叶片性状的差异,以及空间异质性对花芽期和开花期小枝功能性状相关性及其权衡作用的影响。结果表明:低海拔同一生长期陇蜀杜鹃小枝长度显著大于高海拔,高海拔开花期小枝的花数量和花质量显著高于低海拔。同一海拔花芽期的小枝质量、叶片数量、总叶质量、总叶面积和总叶柄质量均显著大于开花期,单叶质量和单叶柄质量均显著小于开花期。与花芽期相比,开花期叶生物量占比减少了13%,而小枝质量占比显著增加。小枝的生物量权衡表明,花芽期性状倾向于小枝质量,开花期倾向于总叶质量;花芽期的叶偏好分配于单叶质量,低海拔和高海拔开花期叶片分别偏好分配到单叶柄质量和单叶质量。低海拔开花期小枝质量与总叶面积、总叶质量均为异速生长,单叶柄质量和单叶面积为异速生长。海拔和发育阶段共同影响了陇蜀杜鹃功能小枝和叶片的性状。 | 何家莉 王金牛 周天阳 宋怡珂 石凝 NIYATI Naudiyal 吴彦 | 2020 | 应用生态学报2020，31，12： | 10 |

| 8 | Phytopharmacological evaluation and anti-asthmatic activity of Ficus religiosa leaves显示文摘Objective:To discuss phytopharmacological potential and anti-asthmatic activity of Ficus religiosa(F.religiosa)(L.).Methods:Fresh leaves of F.religiosa were obtained from Vastrapur Lake,Ahmedabad,and dried to obtain powder.Histamine and acetylcholine were used to guinea pigs to establish bronchospasm model.In in vivo study,the aqueous extract of F.religiosa leaves (AEFR) at doses of 150 and 300 mg/ kg was administrated to guinea pigs,and the broncho-protective activity of AEFR was compared with aminophylline at 25 mg/kg.While in in vitro study,and 10 g/mL,20 g/mL,30 g/mL of AEFRL was administrated to guinea pigs,respectively, and mast cell stabilizing activity of AEFR was compared with ketotifen at 10 g/mL.Results: In the in-vivo model,pre-treatment with aminophylline(25 mg/kg,ip.) could significantly delay the onset of histamine induced pre-convulsive dyspnea,compared with vehicle control. Administration of AEFRL(150 and 300 mg/kg,ip.) also produced significant effect on latency to develop histamine & acetylcholine induced pre-convulsive dyspnea.In the mast cell stabilizing model,AEFRL at 10,20 and 30μg/mL could significantly increase the number of intact cells. Conclusions:It can be concluded that AEFRL is effective on histamine & acetylcholine induced bronchospasm in guinea pigs.In addition,AEFRL can potentiate the number of intact cells in the mast cell stabilizing model._____________________________________________________ | Megha Kapoor Nidhi Jasani Niyati Acharya Sanjeev Acharya Vimal Kumar | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，8： | 3 |
| 9 | The changing Himalayan landscape:pine-oak forest dynamics and the supply of ecosystem services显示文摘This review summarizes the current state of knowledge on pine and oak forest dynamics in the midmontane central Himalayan forest and the ecosystem services associated with these vegetation types. Forest ecosystems play a crucial role in the livelihood of the central Himalayas as well as the adjacent plains, providing a number of tangible and intangible ecosystem services, at each stage of succession. The successional sequence starts from warm temperate grasslands, followed by early successional pine forests, mid-successional pine-oak mixed forests and eventually culminating in a late successional oak community.This successional sequence is considerably influenced by disturbances like fire, grazing, and lopping, which maintain the vegetation types in their current form and can act as potential drivers of change. Fire and grazing in grasslands and pine forests inhibit the successional process by hindering the establishment of pioneer and late successional species,respectively. Potential land-cover changes with forest succession can lead to changes in ecosystem services supply.We found that the number of ecosystem services associated with these vegetation types increase from early to late successional community. Current management approaches fail to include the dynamic nature of vegetation, which is essential for maintenance of ecosystem service supply. In conclusion, the trade-offs between ES of global(biodiversity and carbon) and local importance(fuel wood and fodder)have to be examined carefully in order to have effective conservation and management plans for the region. | Niyati Naudiyal Joachim Schmerbeck | 2017 | Journal of Forestry Research2017，28，3： | 2 |
| 10 | 岷江源区典型高山林草交错带土壤养分的空间变化特征及影响因素显示文摘高山林草交错带是响应全球气候变化的敏感区。林草交错带植被类型和植物群落特征受气候变化和土壤养分状况的共同影响。然而,这一敏感生态带内主要土壤养分状况及海拔梯度特征仍不清楚。本研究于2019年6月上旬,对岷江源区两处高山林草交错带按不同植被带(草甸区−高寒草甸、树种线−亚高山灌丛带、树线−乔灌带、密闭森林−暗针叶林)分别在0−10和10−20 cm土层取土样,测定土壤有机碳、总氮、总磷、pH和土壤水分含量,分析土壤碳、氮、磷和水分含量的空间分布特征及其影响因素。研究发现,植被类型是影响岷江源高山林草交错带土壤理化性质的主要因子;草甸区土壤全碳(total carbon,TC)、全氮(total nitrogen,TN)、有机碳(soil organic carbon,SOC)含量显著低于其他植被带(P<0.05),树种线、树线、密闭森林处土壤TC、TN、SOC含量无显著差异(P>0.05);树线处土壤总磷(total phoshorus,TP)含量显著低于其他植被带(P<0.05);土壤全碳、全氮、有机碳土壤含水量(soil variable water content)间有极显著相关关系(P<0.01),在树种线处土壤各理化性质间相关性最弱;树线处土壤化学计量比较大,且该植被类型带土壤C∶P、N∶P的空间异质性很强。结果表明,虽然岷江源高山林草交错带树种线、树线、密闭森林处的C、N、P含量无显著差异(P>0.05),但树种线和树线处植被对土壤养分间的相互作用影响显著(P<0.05)。 | 宋怡珂 盖艾鸿 周俊 王金牛 孙建 何家莉 查琳 Niyati Naudiyal 周天阳 石凝 白景文 | 2020 | 草业科学2020，37，10： | 2 |

| 13 | The future of mountain agriculture amidst continual farm-exit, livelihood diversification and outmigration in the Central Himalayan villages显示文摘Agrarian patterns in mountain ecosystems have seen a considerable change in the past decades with a vast proportion of the population abandoning traditional agriculture and diversifying their livelihood options, primarily through out-migration. This trend is especially common amongst the subsistence based family-farming communities in developing countries. This study aims at assessing methods of livelihood diversification and factors influencing farm-exit in Central Himalayan villages of Uttarakhand, India, while trying to understand local perspectives on challenges in pursuing agriculture as a viable livelihood option. We collected qualitative and quantitative data from 951 households across 60 villages evenly distributed across six hill districts of Uttarakhand, using key-person interviews and household surveys. The results of the study highlight that farm-exit is significantly influenced by livelihood diversification, number of migrants, number of female family members, and availability of irrigation facilities. In general, perception of the respondents towards agriculture as a viable livelihood option is rather unenthusiastic, with 87% of the respondents citing human wildlife conflict as the main challenge in pursuing farming, amongst several other challenges. Diversification is an integral component of present rural economy with 80.13% of the total population dependent on more than one source of income, to maintain their livelihoods. However, there is no statistically significant influence of livelihood diversification on annual income of the household. If agro-based entrepreneurial ventures are to be promoted in the region there is an urgent need for timely introduction of radical policy, institutional, and land-reforms. Economic uplifting of the local population through such efforts can also be a possible solution to the growing trends of out-migration in the state. | Niyati NAUDIYAL Kusum ARUNACHALAM Ujjwal KUMAR | 2019 | Journal of Mountain Science2019，16，4： | 1 |

| 17 | Petrographical and mineral chemistry evidence to delineate the source/sources of the Central Indian Ocean Basin pumices显示文摘We present data pertaining to mineral assemblages and composition of the Central Indian Ocean Basin(CIOB)pumices.Eight groups of pumices were identified considering the presence of phenocrysts of plagioclase,clinopyroxene,orthopyroxene,hornblende and biotite together with the occurrence of quartz and glass.Pigeonite,fayalite and ulvospinelare reported for the first time from these pumices.In the eight groups,the modal percentage of the constituents are phenocrysts 3%to 19%(avg 9.6%),silicic glass 33%to 54%(avg 43%)and the rest is vesicles.Based on the above factors we have identified the possible sources of the CIOB pumices.The mineral compositions of plagioclase,pyroxenes,and biotite of the CIOB pumices were compared with those of Krakatau and Toba.Most of the plagioclase and pyroxene compositions resemble the Haranggoal Dacite Tuff of Toba and Krakatau.Considering the mineral assemblages and compositions,there are pumices which do not correlate to any of the above eruptions and are probably from yet unidentified source/sources.These sources could either be from nearby terrestrial volcanoes or intraplate seamounts present in the CIOB.In a global context,it is viable that petrological characteristics could be used as initial criteria to determine the source of pumices that occur at abyssal depths in the world ocean. | Niyati G.Kalangutkar Sridhar D.Iyer | 2023 | Acta Oceanologica Sinica2023，42，5： | 0 |
