航空安全文化运行模式研究

依据安全文化基本原理,对航空安全文化模式进行系统化设计。将安全精神文化、制度文化、行为文化和物态文化4个子系统置于安全文化模式的大系统中,综合分析各子系统之间的互动关系及其对管理模式变革的影响。结合航空安全管理的特点,设计安全文化运行机制的结构框架。通过分析安全文化模式的运行过程和运行功能模块,实现航空安全文化模式的动态管理,使零散的安全文化模式得以系统化。航空安全文化模式的构建为航空运输企业建立了一个程序化、系统化、动态循环的管理过程,并以持续改进的思想指导企业系统地实现其安全目标。     

煤矿应急资源优化管理与调度监控研究

为了提高煤矿应急资源在日常的分类分级管理和在突发事故救援过程中的统一调度,把煤矿应急资源划分为人员流、物资流和信息流,并且通过构建煤矿应急资源救援调度模型和建立煤矿应急资源实时监控机制,提高应急资源在突发事故或预案演练中的应急保障能力,最终实现应急资源的日常分类管理、灾时统一调度的应急联动体系。     

赣闽浙三省接合区砂金资源的分布与沉积学特点

赣闽浙三省接合区砂金资源分布广泛,尤以赣东北乐安江、昌江水系最富。本文是在对该区野外调查,取样分析和典型砂金矿床、矿点地质环境分析的基础上,认为冲积型砂金富集与矿源层分布,水系发育规模及地貌条件,含金物质搬运距离,水动力条件,沉积界面微地貌及合金物质沉积后埋藏状况有密切关系,掌握砂金沉积学特点有利于资源的勘探和开发。     

我国淡水水域光合产物的气候生产力探讨

根据太阳辐射在水体中的有效分布、生长季水温和浮游植物光合生态特性等因子,模拟计算了我国大陆东部淡水水域的光合生产力、气候生产力及其季节变化的地理规律。从中得知,这些水域初级产物的年气候生产力主要呈纬向分布,由南向北递减,各地范围在 1.6-24.4gC/m²·a之间,长江以南是>15.0gC/m²·a的高值区,长城以北和四川盆地为<10.0gC/m²·a的低值区,因此,在气候生产力高值区有可能充分利用气候资源优势,开发低成本的自然淡水水域渔业;而在低生产力区,受自然资源的局限其自然捕鱼量需适量控制,因地制宜。     

基于稳健统计的土壤环境背景值研究及应用

使用稳健统计方法中的位置估计量和尺度估计量对我国某受到人为干扰的地下水水源地C层土壤重金属的背景值进行了研究.结果表明,稳健统计方法对样本中的异常值有较高的耐抗性,计算结果与常规方法相近,因而适用于某些人为干扰地区的土壤环境背景值研究.对该水源地背景值的计算表明,该地区C层土壤Cu,Pb,Cd,Cr,As和Hg的背景值中心分别为21.2,32.5,0.103,60.3,11.0和0.012 mg/kg,其中w(Pb),w(Cd)和w(As)高于山东省平均值. 6种重金属的阈值分别为29.0,43.7,0.143,93.5,21.0和0.080 mg/kg,均小于全国平均上限值,但其中Pb,Cr,As的阈值高于土壤环境质量一级标准. 基于该地区背景值的污染累积指数评价表明,该地区主要重金属污染物为Pb和Hg,主要污染区为污水沟渠周边,污染深度为1～3 m.      

OREGON WATER QUALITY INDEX A TOOL FOR EVALUATING WATER QUALITY MANAGEMENT EFFECTIVENESS1

ABSTRACT: The Oregon Water Quality Index (OWQI) is a single number that expresses water quality by integrating measurements of eight water quality variables (temperature, dissolved oxygen, biochemical oxygen demand, pH, ammonia+nitrate nitrogen, total phosphorus, total solids, and fecal coliform). Its purpose is to provide a simple and concise method for expressing the ambient water quality of Oregon's streams for general recreational use, including fishing and swimming. The OWQI, originally developed in the 1970s, has been updated based upon improved understanding about water quality behavior. This report describes the historical basis of the OWQI and defines the improved design of the present OWQI. The index allows users to easily interpret data and relate overall water quality variation to variations in specific categories of impairment. This report demonstrates the value of the OWQI in presenting spatial and temporal water quality information. The OWQI improves comprehension of general water quality issues, communicates water quality status, and illustrates the need for and effectiveness of protective practices.

Monitoring and adaptive management: resolving social and organisational issues to improve information sharing in natural resource management

Adaptive, or 'learning by doing', approaches are often advocated as a means of providing increased understanding within natural resource management. However, a number of organisational and social issues need to be resolved if these approaches are to be used successfully. A case study in the South Island high country of New Zealand is used to review what is needed to support an ongoing community-based monitoring and adaptive management programme. First, the case study is described, paying attention to the social context of the resource management problem. The results of a workshop that explored this problem are then outlined, along with a proposed information flow suggested by participants. Requirements for future steps to resolve these problems (such as information protocols and a multi-stakeholder information system) are discussed. Finally, some broad lessons are drawn from this exercise that could help others developing similar approaches.     

关于炼化企业水资源利用的几点思考

通过对我国水资源状况及石化行业水消耗情况分析,找出我国石化企业新鲜水用量,污水排放在绝对量,吨原油、万元产值的单耗,单排等方面与国外相比较存在的差距。指出存在的主要问题是:清污分流不彻底;污污分流不健全;汽提后的净化水回用量小;新鲜水冲洗地面及作为机泵冷却水直排,导致新鲜水的浪费。同时针对以上问题提出相应的建议参考指标及对应措施。
