1气候变化和社会经济驱动因素共同作用了黄土高原区的植被变绿显示文摘我国在黄土高原区开展了大范围的退耕还林还草工程,植被大范围变绿.但气候因子和人类活动如何共同作用植被变化还鲜有报道.本文利用偏微分方法在黄土高原区294个县定量分解了6个驱动因子(3个气候因子包括降水、气温和太阳辐射,3个人类活动因子包括GDP,人口和家畜量)如何影响植被变化.结果显示,2000~2018年间在284个县植被指数出现了增加的趋势,主要是由于气候因子和人类活动共同影响造成的.6个驱动因子中降水在152个县为植被恢复的主导因子,揭示了气候变化、环境保护和经济刺激政策对区域植被恢复都起到了重要作用.本文对于如何定量分析人类活动和气候变化对植被恢复和区域可持续发展提供了一个理论解析框架.Shahid Naeem 张永强 张选泽 田静 Sawaid Abbas 罗莉莉 Hadush Kidane Meresa 2021Science Bulletin2021,66,12:7
2陕西镇巴县居民慢性病患病情况及影响因素分析显示文摘目的了解陕西镇巴县居民慢性病患病情况及其影响因素。方法采用分层整群随机抽样,对镇巴县15~69岁的常住居民进行慢性病现患情况和相关因素调查。结果共获得有效调查问卷2479份,其中患慢性病963人,慢性病患病率为38.8%。前5位的慢性病分别是高血压(10.1%)、风湿性关节炎(8.0%)、胆结石/胆囊炎(7.0%)、慢性支气管肺炎(6.6%)和消化道溃疡(3.4%)。不同年龄、家庭人口数、婚姻情况、教育程度、职业、收入、饮酒、自我健康评价、健康素养水平的调查对象间慢性病现患率差异有统计学意义。控制其他因素的影响后,55~69岁的人群患慢性病的风险是15~34岁人群的5.34倍(95%CI:3.62~7.84);肉食为主的膳食模式可增加慢性病患病风险(OR=1.36,95%CI:1.04~1.78);自我健康评价差者其慢性病患病风险是自我评价好者的16.41倍(95%CI:10.17~23.33)。结论镇巴县居民慢性病患病率较高,应重点关注自我健康评价较差的老年人,加强两病筛查及改变不良的膳食模式,将有助于改善当地居民的慢性病防控现状。李少茹 朱中海 齐琪 刘美丹 张彬艳 谢馨瑶 Mohamed ELHOUMED Amanual KIDANE ANDEGIORGISH 曾令霞 2020西安交通大学学报(医学版)2020,41,3:6
3Vegetation cover density and disturbance affected arbuscular mycorrhiza fungi spore density and root colonization in a dry Afromontane forest, northern Ethiopia显示文摘Arbuscular mycorrhiza fungi(AMF) are vital in the regeneration of vegetation in disturbed ecosystems due to their numerous ecological advantages and therefore are good indicators of soil and ecosystem health at large. This study was aimed at determining how the seasonal, vegetation cover density, edaphic and anthropogenic factors affect AMF root colonization(RC) and spore density(SD)in Desa'a dry Afromontane forest. AMF RC and SD in the rhizosphere of five dominant woody species, Juniperus procera, Olea europaea, Maytenus arbutifolia, Carissa spinarum and Dodonaea angustifolia growing in Desa'a forest were studied during the rainy and the dry seasons in three permanent study vegetation cover density plots(dense, medium, and poor). Each plot(160 x40 m^2) has two management practices(fenced and unfenced plots) of area. A 100 g sample of rhizosphere soil from moisturefree composite soil was used to determine spore density.Spore density ranged from 50 to 4467 spores/100 g soil,and all species were colonized by AMF within a range of 4–95%. Glomus was the dominant genus in the rhizosphere of all species. Vegetation cover density strongly affected SD and RC. The SD was significantly higher(p < 0.05) in the poor vegetation cover density than in the other two and lowest in the dense cover; root colonization showed the reverse trend. Management practices significantly(p <0.05) influenced AMF SD and RC, with the fenced plots being more favoured. Seasons significantly(p < 0.05) affected RC and SD. More RC and SD were observed in the wet period than the dry period. Correlating AMF SD and RC with soil physical and chemical properties showed no significant difference(p> 0.05) except for total nitrogen. Disturbance, vegetation cover density, season and total nitrogen are significant factors that control the dynamics and management interventions to maintain the forest health of dry Afromontane forests.Emiru Birhane Nakiguli Fatumah Kidane Gidey Amanuel Zenebe Ssemwanga Mohammed 2018Journal of Forestry Research2018,29,3:5
