| 3 | Effects of freezing intensity on soil solution nitrogen and microbial biomass nitrogen in an alpine grassland ecosystem on the Tibetan Plateau,China显示文摘The change of freeze-thaw pattern of the Tibetan Plateau under climate warming is bound to have a profound impact on the soil process of alpine grassland ecosystem;however,the research on the impact of the freeze-thaw action on nitrogen processes of the alpine grassland ecosystem on the Tibetan Plateau has not yet attracted much attention.In this study,the impact of the freezing strength on the soil nitrogen components of alpine grassland on the Tibetan Plateau was studied through laboratory freeze-thaw simulation experiments.The 0–10 cm topsoil was collected from the alpine marsh meadow and alpine meadow in the permafrost region of Beilu River.In the experiment,the soil samples were cultivated at –10°C,–7°C,–5°C,–3°C and –1°C,respectively for three days and then thawed at 2°C for one day.The results showed that after the freeze-thaw process,the soil microbial biomass nitrogen significantly decreased while the dissolved organic nitrogen and inorganic nitrogen significantly increased.When the freezing temperature was below –7°C,there was no significant difference between the content of nitrogen components,which implied a change of each nitrogen component might have a response threshold toward the freezing temperature.As the freeze-thaw process can lead to the risk of nitrogen loss in the alpine grassland ecosystem,more attention should be paid to the response of the soil nitrogen cycle of alpine grasslands on the Tibetan Plateau to the freeze-thaw process. | YANG Zhaoping GAO Jixi YANG Meng SUN Zhizhong | 2016 | Journal of Arid Land2016，8，5： | 5 |

| 5 | Growth–climate response and drought reconstruction from tree-ring of Mongolian pine in Hulunbuir,Northeast China显示文摘Aims Drought affected by atmosphere–ocean cycle is a dominant factor influencing tree radial growth of sandy Mongolian pine(Pinus sylvestris var.mongolica)and regional vegetation dynamics in Hulunbuir,China.However,historical droughts and its correlations with tree radial growth and atmosphere–ocean cycle in this area have been little tested.Methods We developed tree-ring chronologies of Mongolian pine from Hulunbuir,Inner Mongolia,China and analyzed the correlations between tree-ring width index,the normalized difference vegetation index and Palmer drought severity index(PDSI),then developed a linear model to reconstruct the drought variability from 1829 to 2009.Long-term trends and its linkages with atmosphere–ocean cycle were performed by the power spectral,wavelet and teleconnection analysis.Important Findings The local moisture variations affected largely the regional vegetation dynamics and tree-ring growth of Mongolia pine in the forest–grassland transition.Using tree-ring width chronology of Mongolian pine,the reconstruction explains 49.2%of PDSI variance during their common data period(1951–2005).The reconstruction gives a broad-scale regional representation of PDSI in the Hulunbuir area,with drought occurrences in the 1850s,1900s,1920s,mid-1930s and at the turn of the 21st century.Comparisons with other treering drought reconstructions and historical records reveal some common drought periods and drying trends in recent decades at the northern margin zones of the East Asian summer monsoon(EASM).The drying trends in these zones occurred earlier than weakening of the EASM.A REDFIT spectral analysis shows significant peaks at 7.2,3.9,2.7–2.8,2.4 and 2.2 years with a 0.05 significance level,and 36.9,18.1 and 5.0 years with 0.1 significance level.Wavelet analysis also shows similar cycles.Drought variations in the study area significantly correlated with sea surface temperatures in the western tropical Pacific Ocean and middle and northern Indian Ocean,and the Pacific Decadal Oscillation and North Atlantic Oscillation.This suggests a possible linkage with the El Niño-Southern Oscillation,the EASM and the Westerlies. | Zhongjie Shi Lihong Xu Linshui Dong Jixi Gao Xiaohui Yang Shihai Lü Chaoyang Feng Aiyun Song Hao Guo Xiao Zhang | 2016 | Journal of Plant Ecology2016，9，1： | 3 |

| 19 | Three Core Technical Systems and Engineering Application of Regional Lightning Protection显示文摘Regional lightning protection is a complete theoretical system,mainly including:lightning interception technology(LIPT),lightning strong electromagnetic pulse high-energy absorption technology(MSPD),and regional lightning activity law analysis technology(RLLA).Lightning interception technology uses dispersive waveguide resonant cavity technology to achieve the functions of 46.55 m longer than upward leader of ordinary lightning rod,significantly reducing lightning strike point current by 40%,optimizing space electromagnetic field environment,and effectively intercepting overhead and side lightning strikes,and overcome the limitations of traditional lightning rod.The lightning strong electromagnetic pulse high-energy absorption technology uses distributed parameter balance technology,special disconnector for short circuit current,and parity pairing technology to achieve stronger surge absorption capacity than traditional single pulse SPD and international advanced technical indicators such as timely breaking under power frequency short circuit current,and good energy and time coordination.The analysis technology of regional lightning activity laws accurately identifies lightning strike points through comprehensive analysis of regional lightning activity laws,physical parameters of ion clouds,and the impact on ground electric fields.The three core technology systems complement each other,achieving all-round protection against direct lightning strike and lightning electromagnetic pulse.Several projects achieved zero lightning damage,effectively ensuring the safety of buildings and electronic and electrical equipment in the protected area. | Zhen CHEN Yu HUANG Ziqin GAO Yixian QIU Xiaofeng LUO Xiaoning ZHANG Jixi LIU | 2023 | Meteorological and Environmental Research2023，14，3： | 0 |
| 20 | 外源酶添加对人工林凋落物质量残留、养分含量和微生物群落的影响显示文摘凋落物输入对森林土壤性质和生态系统功能有很大影响。凋落物快速分解可减少人工林农业废弃物,促进养分循环。酶是凋落物分解和元素释放的关键角色。然而,有关外源酶制剂对凋落物分解的影响研究却很少。为了探究外源酶如何影响凋落物质量残留率、营养元素释放(C,N,K)和微生物群落多样性,本研究以人工林枇杷(Eriobotrya japonica)凋落叶为研究对象,将5种外源酶(漆酶、木质素过氧化物酶、亮氨酸氨基肽酶、纤维素酶、酸性磷酸酶)施加于凋落物表面后恒温恒湿分解189天。在分解过程中,测定凋落物质量残留率和主要元素含量,分解结束后测定凋落物表面附着的微生物多样性。研究结果显示,漆酶和木质素过氧化物酶通过影响微生物多样性、氮和钾的含量来促进凋落物的分解。亮氨酸氨基肽酶促进了氮元素的富集,从而降低凋落物质量。但纤维素酶、漆酶和木质素过氧化物酶的施加对凋落物中纤维素和木质素的降解没有影响。这些研究结果证明,外源酶施加可改变凋落物的养分含量和微生物群落,从而影响凋落物的分解。综上,为了有效调控农业废弃物凋落物的分解速率,外源酶对凋落物分解的影响是未来的重点研究方向之一。 | Huayue Nie Chenrui Wang Meirong Tian Jixi Gao | 2023 | Journal of Plant Ecology2023，16，6： | 0 |
