| 1 | Developing conservation strategies for Pinus koraiensis and Eleutherococcus senticosus by using model-based geographic distributions显示文摘We described potential changes in the geographic distribution and occurrence probability of Pinus koraiensis Sieb. et Zucc. and Eleutherococcus senticosus(Rupr. et Maxim.) Maxim. in the counties of northeast China. This information was used to identify priority areas for protection and provide protection and management recommendations within each studied county. The two species were mapped in 2884 study plots throughout this region over a 4-year period(38 400N–53 300 N, 115 050E–135 020E). We used the species distribution models(Maxent), systematic conservation planning models(Marxan), and Geographic Information Systems(Arc GIS10.0). The distributions of two species were correlated in the study area, enabling unique and economically viable joint conservation measures to be implemented. Three models were combined to identify feasible priority conservation sites. We used local spatial statistics to assess all identified conservation areas in relation to potential climate change based shifts in the geographic distribution of the two species. Model-based conservation strategies were used to identify effective measures to protect and utilize these two tree species in the study region. This study presents a novel technique for assessing wild plant distributions, in addition to serving as a model for the conservation of other species within the framework of general forest management, ecological construction, and geographical surveying. | Jizhong Wan Chunjing Wang Jinghua Yu Siming Nie Shijie Han Juzhao Liu Yuangang Zu Qinggui Wang | 2016 | Journal of Forestry Research2016，27，2： | 4 |
| 2 | Status and Progress on an HTS Strand with Quasi-isotropic Critical Current显示文摘The coated conductors(CCs),also known as the second-generation high-temperature superconducting(2G HTS)tape,has attractive potential applications in transmissions at low magnetic field/liquid nitrogen temperatures and high-field applications at low temperatures due to their excellent critical current density and mechanical performance.Its critical current density has strong anisotropy,particularly at 77 K.Because the single tape has limited capacity of carrying current,the cable or strand making of multi-tapes,stacked in parallel,is necessary.Within recent years,several cables,such as the Roebel cable,CORC cable,TSTC cable,TS cable,and the HTSCroCo cable,were proposed.This paper presents a status and progress on a type of HTS strand made from REBCO tapes.Its quasi-isotropic critical current is experimentally confirmed for liquid nitrogen temperature,mechanical characteristics,AC losses,thermal stability,and quench characterizations are also researched.Finally,the feasible process for the production of practical length of such strand is described by processing 10 m long sample,which is promising for applications of high fields or power transmission. | Jian Du Jianlong Sun Yang Nie Siming Mo Yuan Cai Huijuan Chen Wen Yuan Yinshun Wang | 2021 | CSEE Journal of Power and Energy Systems2021，7，1： | 0 |
