简介:打区域是巴基斯坦的一个生物多样性中心。植物种类,特别树,在Swat,区域从全球气候暴露于扑灭威胁变化。用HADCM3A2a全球气候变化情形,种类分发的最大的熵(MaxEnt)建模在未来分发预言了一个可观的变化受苦pindrow(Royle前D.Don)Royle。AUC(在曲线下面的区域)0.972和0.983珍视目前是重要的,未来分发分别地种类当模特儿。象最温暖的季度(bio_10)和年度温度范围(bio_7)的吝啬的温度那样的有关生物与气候的变量显著地作出贡献到模型并且因此影响种类的预言的分发和密度,是清楚的。未来模型预言到一年,2080人口密度将显著地减少。种类的最高的密度在Sulatanr和Mankial的区域在山谷的东方、西方的边阶被记录。在种类的密度和分发的变化能有可观的影响,不是仅仅在树种类本身上,但是在联系subflora上也。
简介:摘要院本文首先根据光纤通道的不同种类,对其构成与特点进行介绍,并在此基础上结合其运行中的常见故障,对继电保护光纤通道的维护进行探讨,以此来为今后电力系统的安全运行提供一定的参考依据。
