2000年以来,长江经济带高强度的人类社会经济活动引发了严峻的环境污染问题,灰霾污染尤为严重.研究该区域PM2.5浓度的时空格局与影响因素是落实新发展理念、推进区域大气污染综合防治的迫切需要.本文基于遥感反演数据,研究了2000~2016年长江经济带PM2.5浓度分布格局的演变过程,利用地理加权回归模型揭示了自然和社会经济因素对其影响的时空非平稳性.结果表明:①PM2.5浓度分布总体表现为东高西低,且城市群污染特征明显.②以2007年为界, 2000~2016年PM2.5年均浓度经历了逐年上升和波动下降的过程,年均浓度由27.2μg·m^-3上升至44.1μg·m^-3后, 2016年降至33.6μg·m^-3.污染范围则先由长三角城市群、长江中游城市群和成渝城市群核心区域向四周快速扩展, 2007年后开始往回收缩.③空间自相关分析表明,PM2.5浓度分布有显著的正空间自相关性,热点持续稳定地分布在上海、江苏、安徽中北部、浙江北部和湖北中部,冷点分布在云南、四川西部和南部及贵州西部.④自然因素与社会经济因素对PM2.5浓度分布的影响具有时空差异性.其中社会经济因素主要呈正向影响;自然因素中,降水量主要呈负向影响,其余因子的影响大小和作用方向均随着时间和空间的变化而变化.

科学量化评价农用地集约利用变化过程,对于农业可持续发展有着重要的意义。为此,采用资料综合分析与理论分析相结合的方法,对农用地集约利用变化过程进行了研究。以陕西省扶风县1997-2006年土地利用状况为依据,结合扶风县的自然、社会、经济条件,从投入强度、利用程度、产出效率和持续状况4个层次上构建了农用地集约利用评价的指标体系,采用层次分析法确定了各指标的权重,多因素综合指数法计算历年农用地的集约度分值。研究结果表明,扶风县农用地集约利用水平在1997-2006年呈现递增趋势,但农用地利用持续状况令人堪忧。评价结果基本符合当地实际,具有较强的现实指导意义。

为了解复垦方式对煤矸石山地表节肢动物群落特征影响的差异性,以霍州煤矸石山桃树地、花椒地、荒草地为研究对象,以附近未受煤矸石山影响的玉米地为对照,采用陷阱诱捕法,对地表节肢动物群落进行了调查,并运用物种多样性指数、相似性指数和CCA排序法对地表节肢动物群落结构、多样性以及与环境因子的关系进行分析。结果表明:调查共捕获节肢动物46类3585只,其中桃树地优势类群为疣跳科(Neanuridae)和圆跳科(Sminthuridae),花椒地优势类群为长角跳科(Entomobryidae)和蚁科(Formicidae),玉米地优势类群为蚁科和步甲科(Carabidae),荒草地优势类群为蝗科(Acrididae)、蚜科(Aphidoidea)和蚁科,桃树地常见类群4类,花椒地8类,而荒草地和玉米地的常见类群均为13类,但荒草地个体总数在4种样地中最少;复垦对地表节肢动物类群的活动密度、均匀度、优势度和丰富度均产生显著影响,而对多样性无显著影响。活动密度、均匀度和优势度均表现为荒草地与其他样地存在显著差异,丰富度则表现为玉米地与其他样地存在显著差异;CCA分析表明,土壤速效钾和有机质含量是影响地表节肢动物群落特征的主要环境因子。复垦桃树地有助于更多个体数量的地表节肢动物生存,而复垦花椒地能够显著提升地表节肢动物类群的数目。该结果将为煤矸石山复垦和建设绿色矿山提供理论指导。

BACKGROUND The imbalance of hormone levels in the body is closely related to the occurrence and progression of schizophrenia,especially thyroid *** To study the relationship between triiodothyronine(T3),thyroxine(T4),free T3(FT3),free T4(FT4),thyroid stimulating hormone(TSH)and *** In this study,100 schizophrenia patients were selected from our hospital between April 2022 and April *** clinical data were analyzed *** on the Positive and Negative Syndrome Scale(PANSS)score,patients were divided into mild(1-3 points,n=39),moderate(4 points,n=45),and severe groups(5-7 points,n=16).Additionally,55 healthy individuals served as a control *** blood samples were collected to measure T3,T4,FT3,FT4,TSH,and cortisol concentrations,analyzing their relationship with PANSS *** The serum levels of T3,FT3,FT4,TSH and cortisol in the schizophrenia group were lower than those in the control group(P<0.05).With the increase of the severity of the disease,the concentrations of T3 and T4 decreased,while the con-centrations of TSH and cortisol increased(P<0.05).The concentrations of TSH and cortisol were positively correlated with the PANSS score,while T3 and T4 were negatively correlated with the PANSS score(P<0.05).The receiver ope-rating characteristic curve results showed that T3,T4,TSH,and cortisol had good efficacy in the diagnosis of *** results showed that decreased T3 level,decreased T4 level,decreased TSH level and increased cortisol level may be independent risk factors for *** Thyroid hormone levels are associated with the severity of schizophrenia symptoms,which can provide new solutions for the diagnosis and treatment of schizophrenia.
