1991／1992年夏季南极普里兹湾邻近海域网采浮游植物的聚类分析

本文报道了１９９１／１９９２年南极夏季在普里兹湾邻近海域浮游植物调查的研究结果。经鉴定共有浮游植物３门２６属７８种；其平均细胞丰度为１２０±１７４×１０５个／ｍ３，密集区分布在６２°Ｓ、７８°～１０３°Ｅ，这一海域其细胞丰度在１１０×１０５～８６４×１０５个／ｍ３之间。根据浮游植物种类组成和细胞丰度百分比的聚类分析，测区浮游植物群落中可划分为四个聚合类群：菱形藻（Ｎｉｔｚｓｃｈｉａ）与赖氏针杆藻（Ｓｙｎｅｄｒａｒｅｉｎｂｏｌｄｉ）、长环毛藻（Ｃｏｒｅｔｈｒｏｎｃｒｉｏｐｈｉｌｕｍ）与翼根管藻（Ｒｈｉｚｏｓｏｌｅｎｉａａｌａ－ｔａ）和翼根管藻与赖氏针杆藻占优势的聚合类群及由海冰习性的菱形藻与近岸性角刺藻（Ｃｈａｅｔｏｃｅｒｏｓ）占优势组成的中山站近岸单一生态类群。文中还讨论了浮游植物丰度与环境因子的关系并对过去数年南极浮游植物的调查结果进行了比较     

杭州湾滩涂河口桡足类群落丰度和生物量与水质参数的通径分析

2010年4月~2011年1月期间,在高潮位和中潮位下,分别对杭州湾南岸滩涂排水区和非排水区的5个断面进行桡足类丰度和生物量进行调查。结果表明,共发现15种河口桡足类,包括剑水蚤3种、哲水蚤5种和猛水蚤7种;第一优势种为汤匙华哲水蚤(Sinocalanus dorrii),第二优势种为四刺窄腹剑水蚤(Limnoithona tetraspina);研究区河口桡足类的平均丰度为15.3 ind./L,平均生物量为0.214 mg/L,主要分布在排水区的S3和S2采样断面。在春季采样日,滩涂水中的NO2—N和PO4—P营养盐通过浮游植物生物量影响桡足类群落,浮游植物生物量是河口桡足类丰度发展的决策因子和桡足类生物量波动的限制因子;在夏季采样日,水中的高浓度NH4—N通过NO2—N含量损害桡足类,成为桡足类丰度变化的限制因子;温排水通过减少海水溶解氧含量间接影响桡足类生长,成为桡足类生物量变化的限制因子;在秋季采样日,水中的Si O3—Si含量是桡足类丰度和生物量的决策因子。     

1971—2018 年陕西省人体舒适度时空分布特征研究

根据陕西省 94 个气象观测站 1971—2018 年逐日气象资料,对人体舒适度指数（I_CHB）时空分 布特征及其影响因子权重进行了统计分析。结果表明：（1）陕西近 48 a 省 I_CHB 呈现显著上升趋势, 线性趋势达到 0.07?a^-1,陕北、关中和陕南地区年际变化与全省变化趋势基本一致。四季 I_CHB 变化均 呈上升趋势,其中春季上升趋势最为显著,冬季次之,秋季最低,四季I_CHB 在 2000 年以来增幅减缓。 各区四季 I_CHB年际变化与全省趋势一致,各区I_CHB 夏季差异最小,冬季最大。I_CHB 月变化呈单峰型,1 月最低,7 月最高。（2）陕西各地 I_CHB介于 26～52 之间,体感属于冷、凉和凉爽等级。I_CHB 空间分布差 异显著,陕南地区最高,其次是关中,陕北地区最低。四季 I_CHB 分布特征与全年分布特征相似,均呈 现自北向南逐步升高的趋势。（3）R/S 分析预测未来气温将升高,风速则呈减少趋势,I_CHB 将继续升 高,四季气候舒适性将发生改变。（4）温度（湿度、风速）与 I_CHB 存在显著的正（负）相关关系,温度和 风速是影响陕西省I_CHB的最主要因子,且二者影响程度基本相当,湿度主要通过温度影响 I_CHB。3 个 地区温度的正影响和风速的负影响均较大,关中地区 3 个要素之间互相影响较大;陕北和陕南地区 各要素之间互相影响较小,对 I_CHB的直接影响较大。     

塔里木盆地沙尘天气的季节变化及成因分析

 选取了塔里木盆地周边16个站点,详细分析了沙尘天气的季节变化特征。结果表明：各站点沙尘天气频率虽均以春季最高,但其他3个季节沙尘日数的分布可以分为3种类型：第一种以秋季最高,夏季次之,冬季最低,如喀什和库车地区;第二种以夏季最高,冬季次之,秋季最低,如若羌地区;第三种以夏季最高,秋季次之,冬季最低,这一种类型是塔里木盆地沙尘天气季节分布的主要特征。沙尘天气的季节变化主要受风速和沙源季节变化的影响。当沙尘来源相似时,风速是控制沙尘释放强度的主要因素。     

巴丹吉林沙漠高大沙山近地层温湿廓线与能量交换特征

利用兰州大学冰川与沙漠研究中心科学观测实验站2015—2016年获得的高大沙山微气象数据,分析了巴丹吉林沙漠温湿廓线结构、土壤分层温度、辐射通量等特征,利用组合法和一维热传导方程分别计算了湍流通量及土壤热通量。结果表明：（1）近地层大气自下而上呈现近似等温或逆温分布,冬季逆温层厚度大于夏季。（2）初次观测到逆湿现象,比湿夏季最大,冬季最小,秋季和春季次之,全年平均约为4.2 g·kg^-1,高于塔克拉玛干沙漠。（3）土壤热通量在2月底至5月初振幅较大;感热通量具有显著的平均日变化特征,潜热通量平均日变化平稳,以0 W·m^-2为中心上下波动。能量交换以感热通量为主,陆-气温度差异是沙山感热通量变化的主要影响和控制因子。     

基于 MODIS 和 CloudSat 的京津冀降水冰云季节分布特征

利用 2008 年 9 月~2016 年 8 月 Aqua MODIS 和 CloudSat 卫星数据,筛选出京津冀地区的降水 冰云,同时将其分为 4 个区域讨论,得到关于该地区降水冰云 4 个季节的分布特征,为该地区的人 工影响天气提供依据。结果表明：京津冀整个地区的降水冰云在夏季的发生率都较高,且发生率 有上升的趋势。从整个地区看来,京津冀地区的降水冰云的云顶高度在冬季最低、夏季最高,云顶 温度的最小值在冬季最高、夏季最低;京津冀地区的降水冰云在春夏秋 3 季均以单层云为主,而在 冬季则以双层云为主;京津冀地区的降水冰云的类型按春夏秋冬分别为 7 种、7 种、6 种和 5 种,且在 夏季该地区的降水冰云以深对流云为主（占 48.3%）,而其他季节以雨层云为主;京津冀地区降水冰 云微物理量（包括冰水含量、粒子数浓度、粒子有效半径）主要分布高度分别为 0~13.5 km（春季）、 3.5~17.0 km（夏季）、1.0~14.0 km（秋季）、0~11.0 km（冬季）。冰水含量、粒子有效半径和粒子数浓度 的分布高度和最大值均在夏季最高,但粒子有效半径在秋季最低,冰水含量和粒子数浓度在冬季 最低。这 3 种微物理量随高度的分布特征夏季在京津冀各分区较为一致,都呈单峰结构,在其他季 节差异较大。     

夏季北冰洋楚科奇海微微型、微型浮游植物和细菌的丰度分布特征及其与水团的关系

本文利用2008年我国第三次北极科学考察的机会,分析了夏季楚科奇海微微型、微型浮游植物和细菌丰度的分布特征,并探讨了它们与楚科奇海水团之间的关系。结果表明：与北冰洋的其它海域相比,楚科奇海的微型浮游植物丰度相对较高（0.03~10.23×103 cells/mL）,微微型浮游植物则大致相同（0.01~2.21×103 cells/mL）,而浮游细菌丰度明显较高（0.21~9.61×106 cells/mL）。白令海陆架水与海冰融化混合水和阿纳德尔水浮游植物群落结构不同,夏季随着太平洋水入流水对楚科奇海的日益影响,其水体本身的群落结构可能被外来群落替代。     

广西海湾红树林区海水中氮的生物地球化学特征及其生态效应

2008年1月、5月、8月和11月,对广西壮族自治区合浦县海湾3个红树林区进行调查,并采集水样,研究各区海水中不同形态氮的含量分布、形态特征、相互关系和氮磷比及其对生态环境的影响效应。结果表明,广西壮族自治区合浦县海湾红树林区海水中各形态氮主要以陆源的补充为主,以凋落物的释放补充为辅;其中,总氮、颗粒态氮、溶解态氮和溶解无机氮含量都具有春季、夏季偏高和秋季、冬季偏低的特征,只有溶解有机氮含量具有夏季最高、秋季和冬季次之、春季明显偏低的特征;研究区海水中氮的存在形态主要以溶解态氮为主,其占总氮的81.74%,但在溶解态氮中,溶解有机氮仅以55.06%略占优势;研究区海水中各形态氮含量之间多有显著正相关关系,但四季都能保持高度一致迁移、转化规律的只有总氮与溶解态氮、溶解无机氮和溶解态氮与溶解无机氮,溶解态氮和溶解无机氮无疑成为总氮的主导控制因子。研究区海水中各形态氮含量明显受到环境因子的影响,其中受悬浮物和总有机碳含量的影响较大,受透明度、总碱度、水温和叶绿素a含量的影响次之,受盐度和p H的影响相对较小;研究区海水中各形态氮含量对基础生物量(初级生产力、浮游植物总细胞数和浮游动物总个体数)和浮游生物结构(总种数、丰度、均匀度、多样性指数和多样性阀值)的影响明显,前者以正面影响为主,后者以负面影响为主,春季的影响程度尤为突出;除颗粒态氮与颗粒态磷含量的比值以12.23的明显低值显示氮的相对缺乏外,海湾红树林区海水中的其余4种形态氮含量的比值都在33.07~91.75之间,呈富足状态,尤以溶解无机氮最为显著,这与氮的来源途径较多、转化速率较高有关。     

2007—2020年西藏草面温度时空分布特征

利用2007—2020年西藏38个气象站点平均草面温度（简称草温）、平均气温、平均地表温度、云量、降水量等观测资料,采用气候统计诊断方法分析了西藏草面温度的时空分异特征及其影响因素,以期科学研究当地草地生态系统和开展专业气象服务。结果表明：西藏年平均草温呈自东南向西北递减的分布。草温与海拔高度存在显著的负相关,海拔高度每升高100 m,季平均草温降低0.44~0.70 ℃,年平均草温降低0.58 ℃;与纬度有着显著的曲线关系,29.3°N以南（北）地区,随着纬度增加,草温随之升高（降低）。各站草温呈一峰一谷的日变化特征,日最低值出现在07:00—08:00（北京时间）,日最高值均出现在14:00;草温月平均最低值都出现在1月,月平均最高值出现在6月或7月;76%的站点草温的变化为夏季>春季>秋季>冬季的气候特征。西藏草温年较差为21.4 ℃,较气温年较差偏大3.1 ℃;草温日较差达35.7 ℃,远高于气温日较差,偏大21.6 ℃。草温与气温之差以夏季最大,其次是春季、冬季两者比较接近;草温与地表温度之差以春季最大,夏季次之,冬季最小。在空间分布上,月平均草温与气温、地表温度均呈显著的正相关,与平均风速、积雪日呈显著的负相关;积雪深度对草温的影响,除冬季外二者存在显著的负相关;大部分月份平均草温与总云量、低云量、降水量的关系不显著。86.8%的站点5—9月平均逐小时草温与降水量存在显著的负相关关系。

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.
