安全投入统计指标体系探讨

安全投入统计指标体系在安全生产工作中发挥着重要作用 ,笔者认为 ,建立安全投入统计指标体系之前 ,应对安全投入进行重新定义 ,并按照投入功能的不同将其分为安全工程项目投入、劳动防护与保健投入、应急救援投入、安全宣传教育投入、日常安全管理投入、保险投入和事故投入七大部分。根据安全投入的分类对安全投入统计指标体系结构和具体内容进行了重新设计 ,新的安全投入统计指标体系与安全投入内容相对应 ,分成 7个方面 ,由 34个指标构成 ,不仅对每一个指标进行了清晰定义 ,而且给出了计量单位和具体的计算方法。     

日本安全监督管理启示录

通过对日本安全监督管理机构、研究机构、社团组织和企业的亲身考察 ,对日本安全生产法规建设、监督管理体系、工作机制、主要措施进行了分析、思考和总结 ,认为对如何加强我国安全生产监督管理、改进工作有很大的启示和有益的借鉴。希望文中介绍的内容和观点能在安全生产专家、学者中 ,引起广泛讨论 ,从而建立适合我国国情的安全生产法规体系、安全生产监督管理体系和符合时代发展的创新的安全生产工作思路。

生态环境空间分级管控策略研究

生态环境空间分级管控是为了确保各级尺度下的生态环境空间充分发挥其生态服务功能所采取的管理控制手段与途径,同时给城市生态环境空间的管控提供依据,在不同尺度下,生态环境空间需按照不同精细度的管控方法和不同的土地空间单位进行分级,生态环境空间分级管控主要包括:省域尺度生态环境空间的管控、市域尺度生态环境空间管控和在主城区尺度下生态环境空间管控。通过3种尺度不同管控方法和策略的有效衔接,从宏观、中观和微观3个层次保证了生态规划的完整性和连续性,使生态系统服务真正发挥其价值。     

A grassland ecosystem model of the Xilingol steppe, Inner Mongolia, China

The natural grassland ecosystem of the Xilingol steppe has traditionally been the source of the most productive and highest quality agriculture in northern China. Unfortunately, the area is now experiencing degradation due to resource overuse. In an attempt to forecast grassland production and to sustain the ecosystem, we built a time-dependent simulation model of the ecosystem based on long-range weather forecasts (several weeks to several months). The model incorporated five state variables including above- and belowground biomass, the amount of standing dead plant material, livestock (sheep) weight, and the amount of excrement per unit ground area. Within the model, solar light energy is fixed by grassland vegetation and flows through the other variables via a variety of organism-environment interactions. The model was written using a set of simultaneous differential equations and was numerically analyzed. The values of the time-dependent parameters controlling energy flow were determined based on data accumulated in experiments and field surveys executed at a grassland experimental station located in Xilingol, as well as by reference to related literature. We used daily meteorological data including air temperature and rainfall recorded at the Xilinhot Meteorological Observatory. Simulated results for several stocking densities coincided well with the data of aboveground plant biomass observed at the experimental station in 1990, 1993, and 1997. We obtained reasonable simulation results for five stocking densities, three air temperature patterns, and five rainfall patterns. When a month-long drought, which sometimes occurs in this area, was forecast by a local weather station, a decrease in grassland production was forecast by the model. Such forecasts will assist in the management of livestock, forage preservation, and grassland conservation.     

Beyond barriers: examining root causes behind commonly cited Cleaner Production barriers in Vietnam

Despite the promotion of Cleaner Production (CP) by government, academia and research institutions in the past few years, only a small number of Vietnamese industries have adopted it. This paper explores why CP has not been widely adopted by industry through an examination of the root causes preventing effective CP implementation in Vietnam. The paper concludes with possible directions for improving the effectiveness and sustainability of CP programs in Vietnam through training and education.
