1不同间作枣园害虫的群落结构与动态(英文)显示文摘对5种不同间作枣园的害虫群落结构特征进行了研究,结果表明,在不同的间作枣园中,害虫的科、种与个体数是各不相同的,其多样性、均匀度和Berger-Parker指数也有明显差异(p<0.05).间作牧草或保留杂草的枣园,害虫的科与种以及多样性和均匀度明显(p<0.05)大于间作小麦、大豆和单作枣园,而个体数和Berger-Parker指数则显著(p<0.05)小于单作枣园.枣园害虫个体数的时序动态随季节交替而有明显(p<0.05)的变化,4~8月份害虫的个体数明显(p<0.05)大于3月份、9~10月份.在枣园间作作物、牧草或者适当保留一定数量的杂草,不仅能够充分有效地利用枣园的空间和自然资源,而且增加了生物的多样性,改善了枣园的生态环境,同时提高了有害生物相互制约的能力和枣园单位面积的纯收入.师光禄 赵莉蔺 苗振旺 刘素琪 曹挥 LI Shi-You Bruce PIKE 2005生态学报2005,25,9:33
2不同生境类型枣园中节肢动物群落结构特征(英文)显示文摘在山西太谷枣区对不同间作生境组合类型枣园的节肢动物群落结构特征进行了研究,结果表明,在有杂草的枣园与其他枣园相比,节肢动物的物种数最大(P<0.05),而节肢动物物种的个体数最小(P<0.05),而在单作无杂草的枣园则相反(P<0.05)。植食性类群的物种数和个体数在单作无杂草的枣园显著(P<0.05)大于其间作类型的枣园,而捕食性和寄生性的物种数和个体数则明显(P<0.05)小于其间作类型的枣园,而在有杂草的枣园则相反。枣树与大豆和棉花间作枣园的捕食性和寄生性的物种数和个体数则明显(P<0.05)大于枣树与大豆间作的枣园,而枣树与大豆间作的枣园与单作无杂草枣园的寄生性的物种数和个体数则无明显差异(P>0.05),但捕食性的物种数有大豆的枣园明显(P<0.05)大于单作无杂草枣园,而个体数则无明显差异(P>0.05)。多样性均匀度和相对稳定性指数研究结果表明有杂草的枣园明显(P<0.05)大于单作无杂草枣园,枣树与大豆和棉花间作的枣园明显(P<0.05)大于枣树与大豆间作的枣园,而优势度则相反。研究结果进一步表明,在枣园合理间作多种作物或者适当保留一定的杂草,不仅可以减少天敌昆虫迁出枣园,而且还可以增加枣园天敌的物种数量和节肢动物群落结构的多样性和均匀度,同时还能有效地利用枣园的空间和自然资源,增加单位面积的产量。师光禄 赵莉蔺 苗振旺 刘素琪 曹挥 Shiyou LI Bruce PIKE 2005昆虫学报2005,48,4:25
3枣园害虫、捕食性和中性昆虫群落结构及动态研究(英文)显示文摘对山西省太谷地区枣园的害虫、捕食性和中性昆虫群落结构及动态进行研究,结果表明,不同年份枣园的害虫、捕食性和中性昆虫种类与数量均有明显差异(P<0.05),且树上明显大于地面.不同年份捕食性和中性昆虫与害虫的物种数和个体数比例也不同,其物种数和个体数随季节的暖和冷而增加和减少.相同亚群落不同季节的垂直分层结构相似程度不同,不同亚群落在同一季节的垂直分层相似性也不同.总体上垂直分层明显.枣园害虫、捕食性和中性昆虫的多样性指数随季节变化而波动.捕食性和中性昆虫与害虫数量起伏跟随紧密,总体呈极显著相关(r=0.9833,P<0.05).层次间差异明显,以中层相关最显著(r=0.9887,P<0.01).师光禄 赵莉蔺 刘素琪 曹挥 LI Shiyou PIKE Bruce 2006应用生态学报2006,17,1:15

8Accelerated design and discovery of perovskites with high conductivity for energy applications through machine learning显示文摘We use machine learning tools for the design and discovery of ABO3-type perovskite oxides for various energy applications,using over 7000 data points from the literature.We demonstrate a robust learning framework for efficient and accurate prediction of total conductivity of perovskites and their classification based on the type of charge carrier at different conditions of temperature and environment.After evaluating a set of>100 features,we identify average ionic radius,minimum electronegativity,minimum atomic mass,minimum formation energy of oxides for all B-site,and B-site dopant ions of the perovskite as the crucial and relevant predictors for determining conductivity and the type of charge carriers.The models are validated by predicting the conductivity of compounds absent in the training set.We screen 1793 undoped and 95,832 A-site and B-site doped perovskites to report the perovskites with high conductivities,which can be used for different energy applications,depending on the type of the charge carriers.Pikee Priya N.R.Aluru 2021npj Computational Materials2021,,1:3
