Implementation of two new resource management information systems in Australia

This paper describes the development and implementation ofPREPLAN, A Pristine Environment Planning Language and Simulator, for two conservation areas in Australia, Kosciusko National Park (New South Wales) and Tutanning Nature Reserve (Western Australia).PREPLAN was derived from the North American gradient modeling systems and theForest Planning Language and Simulator (FORPLAN), but includes unique characteristics not previously available.PREPLAN includes an integrated resource management data base, modules for predicting site-specific vegetation, fuels, animals, fire behavior, and fire effects, and an English language instruction set.PREPLAN was developed specifically to provide available information and understanding of ecosystems to managers in a readily accessible and usable form, and to provide the motivation to conduct additional required research projects. An evaluation of the system's advantages and limitations is presented, and the way the utilization of such systems is improving natural area decision making throughout Australia is discussed.     

基于STAMP模型的建筑事故致因因素定量分析方法研究

为揭示建筑安全事故致因因素间的相互关系从而对其进行有效预防和控制,探讨1种STAMP模型的定量分析方法,用于深入剖析事故致因因素间的逻辑关系和属性特征。基于STAMP系统事故理论模型,从建筑工程安全控制结构入手逐层定性分析事故的致因因素;引入灰色DEMATEL与ISM相结合的方法对系统事故间的复杂逻辑关系进行层级划分;运用MICMAC分析计算各致因因素的驱动力和依赖度数值并判断其属性类别。结果表明:提出的定量分析方法运用到江西丰城冷却塔坍塌事故中的分析结果与事故调查报告相契合,能较全面地说明各层次结构间的相互作用。     

基于遥感影像的2019-2020年盐城市生态保护红线区人类活动动态分析

以盐城市生态保护红线区为研究对象,选用哨兵-2号卫星遥感影像进行目视解译及变化斑块提取,分析其区域内2019-2020年人类活动的变化趋势.结果显示,动态变化情况分为正变化和逆变化,其中逆变化占变化总面积的绝大部分,主要呈现为水田的减少;正变化主要呈现为农村居民点的拆除.总体来说,人类活动变化面积非常少,无工业用地的增...
