Peleoecologlcel evidence end peleoclimatlc records indicate that there wee e plant polewerd migration in latitude and an upward shift In elevation with increased temperatures after the last glaciation. Recent studies have shown that global warming over the past 100 years has been having a noticeable effect on living systems. Current global warming Is causing a poleward and upward shift In the range of many plants and animals. Climate change, In connection with other global changes, is threatening the survival of a wide range of plant and animal species. This raises the question： can existing reserves really preserve current levels of biological diversity In the long term given the present rapid pace of climate change？ The present paper deals with this question In the context of the responses of plants and animals to global climate change, based on a literature review. Consequently, we recommend expanding reserves towards the poles and/or towards higher altitudes, to permit species to shift their ranges to keep pace with global warming.

本文使用不同类型(KH550和KH560)和不同浓度(0.5%、1.0%、1.5%和2.0%,质量分数)的SCA对聚丙烯纤维(PPF)进行表面改性,通过无侧限抗压强度试验和抗折试验,研究了SCA改性聚丙烯纤维水泥基复合材料的承压能力,并使用扫描电子显微镜对改性后的聚丙烯纤维水泥基复合材料进行了微观表征。结果表明:KH560改性聚丙烯纤维对水泥基复合材料的流动度影响较大,KH550次之;整体上,SCA浓度越接近1.5%,对聚丙烯纤维水泥基复合材料流动度的影响越大;随着KH550浓度增大,水泥基复合材料孔隙率总体呈降低趋势,随着KH560浓度增大,水泥基复合材料孔隙率呈先下降后上升的趋势,并且浓度为1.5%时孔隙率最小;两种SCA均提高了PPF表面的粗糙度,并能在PPF-SCA-基体界面实现化学键连接;两种SCA对聚丙烯纤维水泥基复合材料抗折强度的影响较小,但能有效提高抗压强度。总体而言,KH550改性效果优于KH560。
