江苏科技信息网之天文数据库

中国科学院紫金山天文台受江苏省科工委、江苏省科技信息中心委托研制的天文数据库,是省科技信息网的重要组成部分。该信息网包括工业、农业、土壤、地理等较为全面的科技信息,将于年底全面开通。天文数据库已于十月中旬上网。它包括了阴阳历对照、行星特殊天象、太阳、恒星、人造地球卫星等方面的内容。用ＦｏｘＰｒｏ５ ．０ 建立的天文数据库管理系统,包括了成百个数据库表,数据量５ 兆左右,记录约为５ 万余条。天体力学部和天体物理部等有关部门,在提供数据方面,给予了大力支持,在此一并表示感谢。     

GEOEssential – mainstreaming workflows from data sources to environment policy indicators with essential variables

ABSTRACT

When defining indicators on the environment, the use of existing initiatives should be a priority rather than redefining indicators each time. From an Information, Communication and Technology perspective, data interoperability and standardization are critical to improve data access and exchange as promoted by the Group on Earth Observations. GEOEssential is following an end-user driven approach by defining Essential Variables (EVs), as an intermediate value between environmental policy indicators and their appropriate data sources. From international to local scales, environmental policies and indicators are increasingly percolating down from the global to the local agendas. The scientific business processes for the generation of EVs and related indicators can be formalized in workflows specifying the necessary logical steps. To this aim, GEOEssential is developing a Virtual Laboratory the main objective of which is to instantiate conceptual workflows, which are stored in a dedicated knowledge base, generating executable workflows. To interpret and present the relevant outputs/results carried out by the different thematic workflows considered in GEOEssential (i.e. biodiversity, ecosystems, extractives, night light, and food-water-energy nexus), a Dashboard is built as a visual front-end. This is a valuable instrument to track progresses towards environmental policies.

新丰江地震目录数据库系统的研制

新丰江地震目录数据库录入了１９６０—１９６９年新丰江水库区的地震目录共计３１３００条。数据库管理系统中的震中位置由直角座标转换为用经纬度表示，具有地震目录检索和统计２大功能，并针对新丰江地震的分区研制了专用软件模块。该系统采用模块化分层结构，增加了软接口，为系统的扩充和拓展打下了基楚。

Evaluation of acid-producing sulfidic materials in Virginia highway corridors

Road construction through sulfidic materials in Virginia has resulted in localized acid rock drainage (ARD) that threatens water quality, sedimentation, integrity of building materials, and vegetation management. Geologic formations associated with acid roadcuts were characterized by potential peroxide acidity (PPA), expressed as calcium carbonate equivalence (CCE), and total sulfur (total-S) in order to develop a statewide sulfide hazard rating map. The geologic formations were grouped into four categories based on potential acid-producing severity: i) Tabb formation (PPA<6 Mg CCE/1000 Mg; S<0.2%); ii) Ashe formation (PPA<18 Mg CCE/1000 Mg; S<2.0%); iii) Chesapeake Group, Lower Tertiary deposits, Millboro shale, Marcellus shale, and Needmore Formation (PPA<60 Mg CCE/1000 Mg; S<2.6%), and; iv) Chattanooga shale and Quantico slate (PPA<99 Mg CCE/1000 Mg; S<3.9%). Sulfide hazard analysis should be an essential step in the pre-design phase of highway construction and other earth-disturbing activities.
