收藏中国劳动力动态调查
“中国劳动力动态调查” (China Labor-force Dynamics Survey,简称 CLDS)是“985”三期“中山大学社会科学特色数据库建设”专项内容,CLDS的目的是通过对中国城乡以村/居为追踪范围的家庭、劳动力个体开展每两年一次的动态追踪调查,系统地监测村/居社区的社会结构和家庭、劳动力个体的变化与相互影响,建立劳动力、家庭和社区三个层次上的追踪数据库,从而为进行实证导向的高质量的理论研究和政策研究提供基础数据。

Paper III (Walker et al. 2024)
Data products used in 3-D CMZ Paper III, Walker et al. (2024). The full cloud catalogue is provided in tabular format, along with a full CMZ map showing the clouds and their assigned IDs. For each cloud ID in the published catalogue there are: - Individual cube cutouts from the MOPRA 3mm CMZ survey (HC3N, HCN, and HNCO). - Individual cube cutouts from the APEX 1mm CMZ survey (13CO, C18O, and H2CO). - Cloud-averaged spectra of the ATCA H2CO 4.83 GHz line. - PV slices of the ATCA H2CO 4.83 GHz line, taken across the major axis of the source. - Where applicable, there are mask files which correspond to the different velocity components of the cloud. In these cases, there are two mask files per velocity component, corresponding to the different masking approaches described in the paper.

中国区域250米植被覆盖度数据集(2000-2024)
该数据集是中国区域2000至2024年月度植被覆盖度产品,空间分辨率250米,合成方式采用月最大值合成,每年12期,共299期。本产品采用基于归一化植被指数(NDVI)像元二分模型,根据土地利用类型确定纯植被像元值和纯裸土像元值,实现植被覆盖度计算。本产品去除湖泊、河流、冰川/永久积雪等区域。其中,NDVI数据来源于国家青藏高原科学数据中心中国区域250米归一化植被指数数据集(2000-2024)产品。通过时空变化趋势分析检验法分析,该数据集符合时间变化趋势和空间变化趋势。该数据集能够为全国区域生态质量评价、重要生态空间调查评估等工作提供数据参考。

SIMBAD Astronomical Database
SIMBAD astronomical database is the world reference database for the identification of astronomical objects and provides basic data, cross-identifications, bibliography and measurements for astronomical objects outside the solar system. Using VizieR, the catalogue service for the CDS reference collection of astronomical catalogues and tables published in academic journals and the Aladin interactive software sky atlas for access, visualization and analysis of astronomical images, surveys, catalogues, databases and related data. Simbad bibliographic survey began in 1950 for stars (at least bright stars) and in 1983 for all other objects (outside the solar system)
