由两颗卫星组成的环境卫星星座系统所提供的CCD数据具有较高的时间分辨率,使其在内陆湖泊水环境遥感监测中具有较大的应用潜力,对其有效的大气校正方法的研究则是其定量化参数反演的前提.基于准同步的MODIS数据辅助,根据气溶胶的差异性,将太湖划分为北部湖区、其他湖区两块区域,利用辐射传输模型,研究太湖环境一号CCD数据大气校正的方法,并对2009年4月17、21、25日数据进行大气校正.研究结果表明,该大气校正方法直接使用较为成熟的MODIS各类产品,克服了传统大气校正中依赖于现场同步测量大气参数的缺陷,能够快速、有效地完成环境一号CCD数据的大气校正.基于气溶胶类型对太湖进行分区后,所求算的遥感反射率精度高于6S模型和暗像元等大气校正方法得到的结果.

根据2009年6月巢湖32个样点的实测数据,分析巢湖水体漫衰减系数光谱特征、主导因子、空间分布规律以及400-700nm各波段Kd与Kd(490)之间的关系,并在此基础上,建立了Kd的遥感反演模型.结果表明:巢湖水体Kd具有一致的光谱特征,400-600nm之间Kd随波长的增加呈指数衰减趋势,在600-700nm之间的变化较小,部分点位在波长675nm附近出现峰值,700-900nm之间Kd呈现出类似于纯水的吸收光谱特征;巢湖中无机颗粒物是水体漫衰减的主导因子,有机悬浮物影响次之,CDOM的影响最小;巢湖东半湖区Kd(490)普遍高于西半湖区,巢湖中部Kd(490)等值线分布较密集,湖区其他部分则相对稀疏;利用591、702、842nm处的遥感反射率进行多元线性回归反演得到的Kd(490)与实测Kd(490)之间的平均相对误差为7.85%;同时,400-550nm波段范围内,可以利用线性关系和Kd(490)对Kd(λ,λ≠490nm)进行参数化表示,在550-700nm波段范围则可采用常数与Kd(490)的乘积来表示Kd(λ,λ≠490nm).通过遥感反射率反演Kd(490),进而推算Kd(λ),其结果与实测Kd之间的平均相对误差为6.14%.

文章介绍了"萤火1号"卫星对火星空间环境磁场进行探测的目的、意义及采用的方式方法.研究火星的空间环境离不开火星磁场,它对于火星弓激波、磁鞘、电离层、大气等绝大多数空间环境效应都有着深刻的影响,因此"萤火1号"卫星安装了一台重要的科学探测载荷——高精度磁强计,以满足科学研究和应用目标的需求.磁强计从原理选择到具体设计,都考虑到了火星轨道严酷的工作环境和科学目标所需的测量要求.通过"萤火1号"装星前的地面标定测试实验,验证了高精度磁强计可以在-140—75℃温度范围内测量±256nT以内的磁场,分辨率达到了0.01nT,带宽内总噪声小于0.03nT,能够胜任"萤火1号"对火星空间环境探测的科学任务."萤火1号"火星探测器将于2011年与俄罗斯的"福布斯-土壤"一同飞往火星,这是人类送往火星最精密的磁场探测器之一,将对火星空间环境磁场结构和动力学过程进行精密而详细的探测.

长江是中华民族的母亲河，为了落实长江大保护，农业农村部统筹部署设立长江渔业资源与环境调查(2017—2021)。由中国水产科学研究院总牵头，中国水产科学研究院长江水产研究所技术总协调，联合流域内外24家科研院所和高校，对长江流域重点水域的鱼类种类组成及分布、鱼类资源量、濒危鱼类、长江江豚、渔业生态环境、消落区、捕捞渔业和休闲渔业等7个专题开展了系统调查。调查结果显示，(1)长江历史(2017年前)分布鱼类记录有18目37科163属443种，本次调查中有135种鱼类未采集到，新采集到15种外来鱼类；(2)当前鱼类资源数量约为8.86亿尾，重量约为12.48万t，仅相当于20世纪50年代的27.3%、80年代的58.7%，流域性优势种为鲤、鲫、鲢、黄颡鱼、短颌鲚、鲇、蛇、草鱼、光泽黄颡鱼、?、鳜、铜鱼、翘嘴鲌、鳊、鳙，重量占比达50%，数量占比达45%；(3)长江流域的国家一、二级重点保护鱼类29种(属)，本次调查共记录到15种，白鲟已被IUCN认定灭绝，鯮和鲥已多年未见野生个体，长江鲟被IUCN认定野外灭绝，中华鲟、胭脂鱼和松江鲈多年未见自然繁殖；(4)2017—2021年，长江中下游干流、洞庭湖和鄱阳湖的长江江豚个体数量整体稳中有升，分布范围有所扩大；(5)长江流域水质总体较好，整体符合渔业水质标准；(6)长江流域重点水域2019—2020年最大水面19 663 km2，最小水面14 281km2，消落区总面积6 337 km2，其中反季节性消落区633 km2；(7)禁捕前，长江捕捞渔业从业者以初中学历以下的中老年为主。调查结果表明，长江全面禁捕退捕是长江水生生态系统保护的生态工程，更是渔民产业转型生存条件改善的民生工程，禁捕后鱼类资源将有显著恢复，长江江豚种群规模也有望稳中有升，但濒危鱼类的处境依然堪忧，衰退的消落区将成为制约未来长江水生生态系统恢复的限制性因素。作为长江流域重要水域全面禁捕前展开的系统调查，本调查结果可以为长江禁捕效果评估提供基准。

2005年是中国承诺碳减排目标的基准年份,因而也是中国城市碳减排战略制定和近中期低碳转型的基准年份和对照年份。中国城市2005年CO_2排放数据的一致性、全面性和精准性对于中国所有城市和每个具体城市的目标考核和评估都有重要意义。基于中国高空间分辨率网格数据(CHRED 2.0)、城市层面统计数据以及大量现场调研和走访,建立2005年中国城市CO_2排放数据集,包括工业能源排放、工业过程排放、农业排放、服务业排放、城镇生活排放、农村生活排放、交通排放7个部门的直接排放数据和间接排放数据。该数据集的建立汇总了86名研究人员的工作成果,在企业、城市不同行业与部门、城市工业和城市总化石能源等不同层面进行了大量的交叉验证和数据分析,有效保障了数据的精确性和准确性。结果显示,2005年中国城市碳排放呈现出较大的体量差异和空间格局差异。排放前10的城市几乎比排放后10的城市的排放量高出两个数量级。高排放城市基本都是城市群的核心城市。东部城市直接排放占全国直接排放比例最高,达到44.59%,其次是西部城市21.76%,中部城市22.70%,东北城市10.95%。
