| 1 | 气候变暖对中国栓皮栎地理分布格局影响的预测显示文摘利用DIVA-GIS软件对中国栓皮栎的地理分布及气候特征进行研究,并用该软件中的Bioclim和Domain两个模型评估未来潜在分布区对气候变暖的响应.结果表明:中国栓皮栎分布区可分为横断山脉区、云贵高原区、华北山地区、华东山丘区、辽鲁半岛区、台湾海岛区和秦岭巴山区7个亚区,跨越7个温度带、2个干湿区、17个气候区,包括8种气候类型.秦岭-大巴山-伏牛山为栓皮栎的现代多度中心.适合栓皮栎生长的年平均温度为7.5~19.8℃,年降雨量为471~1511 mm.Domain和Bioclim模型的受试者工作特征曲线下的面积(AUC值)分别为0.910、0.779,前者预测的高度适生区为秦岭、大巴山、伏牛山、桐柏山、大别山、云贵高原东部和西部、苏皖南部丘陵和华北部分山地.气候变暖趋势下栓皮栎潜在分布区可能向北回缩,面积减小. | 李垚 张兴旺 方炎明 | 2014 | 应用生态学报2014，25，12： | 23 |
| 2 | 基于SWAT模型分析淮河流域中上游水量平衡要素对气候变化的响应显示文摘本研究在对SWAT模型进行参数化的基础上,采用淮河干流吴家渡和鲁台子水文控制站1971—1990年和1991—2014年的月径流观测数据对SWAT模型进行了率定和验证。模拟效果评估结果显示:不论是率定期还是验证期,NashSutcliffe系数Ens和确定系数R^2均>0.8,相对误差R_e<1%,模型能够较好地再现月尺度的降雨~径流过程。淮河中上游年径流深线性变化趋势不明显,但子流域空间差异显著,径流深上游及南部呈线性减小趋势,其他子流域呈增大趋势。从年水量平衡要素来看,蒸散量和渗漏量对水量平衡贡献最大。主成分分析表明,平均气温、降水量及蒸散量是淮河中上游水文要素变化的关键因子。剔除人为因素的影响,1971—2014年淮河中上游地区水资源量呈减少趋势,这可能是年平均气温升高、年降水量略有减少以及年蒸散量减少综合作用的结果。本文研究成果可为准河中上游水资源管理和相关政策的制定提供技术支撑。 | 王胜 许红梅 高超 徐敏 | 2015 | 气候变化研究进展2015，11，6： | 11 |
| 3 | Species delimitation and phylogeography of Abies delavayi complex: Inferred from morphological, molecular, and climatic data显示文摘The species delimitation within Abies delavayi complex,consisting of A.delavayi Franch.,A.fabri(Mast.)Craib,A.nukiangensis W.C.Cheng&L.K.Fu,and A.delavayi subsp.fansipanensis(Q.P.Xiang,L.K.Fu&Nan Li)Rushforth,has been a subject of long term dispute.We combined different lines of evidence,including morphological characters,population-based mitochondrial DNA and chloroplast DNA sequences,and plastome data to assess its species delimitation.These four independent datasets revealed a consistent result that the four taxa of A.delavayi complex were hardly separated and could be regarded as one species.Our results further suggested that these four taxa might have experienced rapid morphological diversification,following a common expansion triggered by climate osilltions during the Pleistocene.In addition,we surveyed the phylogeographical history of A.delavayi complex as a whole based on ecological niche models and molecular data.These results consistently revealed that this high-mountain fir complex had experienced glacial expansion and interglacial contraction.Therefore,we propose that A.delavayi complex probably has undergone the phalanx expansion model in response to climate change during the Quaternary.Such expansion patterns demand consideration when establishing conservation strategies for threatened fir species. | Yi-Zhen Shao Yun Chen Xian-Chun Zhang Qiao-Ping Xiang | 2020 | Journal of Systematics and Evolution2020，58，3： | 1 |
| 4 | Vegetation-environment relationship in Pinus wallichiana forests of the Swat Hindukush range of Pakistan显示文摘Understanding the influence of environmental variables on the spatial distribution of ecological communities is essential to predict the response of vegetation to various environmental drivers.Ecological theory suggests that multiple environmental factors shape local species assemblages and should influence the various components of community structure and composition in different ways.This study aimed to classify Pinus wallichiana dominated forests in the Swat Hindukush range mountains to understand the relative influence of multiple environmental filters on its composition and structure.These forests represent the most typical of the species distribution in northern Pakistan and were not subjected to any phytosociological study.For this purpose,thirty forest stands,spanning a wide range of physical habitats were sampled using 10910 m plots and the importance value index was calculated.The floristic and environmental data were subjected to Ward’s agglomerative cluster analysis for objective classification and ordinated with NMS ordination for pattern description and testing the vegetation–environmental relationships.Three floristically and ecologically distinct communities were recognized along the topographic gradient(elevation,r=0.377;slope,r=0.5548)coupled with soil physical(clay,r=0.2782;silt,r=0.3225)and chemical properties(pH,r=0.4975;lime,r=3982).An elevation gradient of 100 m separated the low(Pinus wallichiana–Quercus dilatata community)and middle elevations forest stands(P.wallichiana pure population)from the highland population type(Pinus wallichiana–Cedrus deodara community).The floristics and structure of these forest types respond directly or indirectly to topographic and soil variables which were evidenced from the floristic composition,species richness,and community physiognomy.These characteristics of the communities changed from heterogenous,dense stands to sparsely dispersed conifers,broadleaved-evergreen,and deciduous vegetation types along the environmental gradients.We concluded that several factors explained the spatial pattern.Thus,we predict that elevation coupled with soil physical and chemical properties could be considered if the ultimate goal is the restoration and conservation of these forests.We also recommend broad-scale phytosociological study on P.wallichiana forests including multiple sampling from diverse locations to define the floristic diversity and to better understand its ecological requirements. | Inayat Ur Rahman Nasrullah Khan Kishwar Ali Siraj Ahmad | 2020 | Journal of Forestry Research2020，31，1： | 0 |
