一种新型数据编码方案——简拼编码法

作者根据多年野外测图实践经验,在对当前应用较为广泛的几种主流数据编码方案——全要素编码、块结构编码、简编码和二维编码方案的编码规律及优劣性对比分析的基础上,提出了一种适用于全站仪测站式测图及GPS手簿式数据采集的全新数据编码方案——简拼编码法。其编码方式简洁,含义明确、易记,使用上输入方便,野外采集效率较高,是一种新型高效的全数字测图编码方式。     

水坝工程建设与生态保护的利弊关系分析

针对当前世界范围内对水坝政策的转变,提出了水坝工程建设与生态环境资源保护的利弊关系概念并建立了指标体系,通过进行利弊关系分析来论证水坝工程建设的可行性。文中以某水坝为例作了利弊关系分析,得出了弊大于利的结论。

气象预警预报培训效果影响因素浅析

通过对2021年中国气象局气象干部培训学院湖北分院举办的气象预警预报培训的107名学员进行问卷调查,使用层次分析法对调查数据进行分析,得出学员的学习态度、学习能力、学习意愿、单位领导的支持和培训教师的授课水平是影响气象预警预报培训效果的主要因素。其中,属培训对象的因素有5项,属培训组织的有3项,属培训环境的有2项。在培训教育中应充分调动培训学员的主观能动性,从师资水平和培训设计上提升培训效果,并创造良好的培训环境以保障培训效果。     

基于初始规划网的镶嵌线自动生成方法研究

针对地理国情普查底图制作过程中数据量大、时间紧、采用传统的镶嵌线生成方法费时费力等问题,提出了基于初始规划网的镶嵌线自动生成法。该方法先利用顾及面要素法和泰森多边形获得初始规划网,然后利用相关系数算法选择最优镶嵌线,最后进行接边纠正。研究表明,该方法可完全满足地理国情普查DOM制作的精度要求,且能大大提高DOM的生产效率。     

Transfer patterns in Phase I of the EU Emissions Trading System: a first reality check based on cluster analysis

In 2005, the world's largest Emissions Trading System (ETS) was introduced in the EU. Economic theory assumes high efficiency of such market-based instruments since companies have the flexibility to trade allowances. However, to date there is a lack of understanding on how companies have participated in the allowance markets. This article uses data on transfers of allowances between 2005 and the end of 2007, published by the EU in the Community Independent Transaction Log (CITL) after a five-year delay. We use cluster analysis to detect patterns in the data and differentiate transfer behaviour. We find that the vast majority of participants (7212 accounts) are rather passive in terms of transfers. Of these, more than half are hardly participating in the market at all, whereas one-third are accounts managed by another account belonging to the parent company. Opposed to that, 143 accounts show more active, but relatively diverse transfer behaviour. We also identify differences in sectoral representations, account types, and primary allocation across the seven clusters. While the passive accounts mostly belong to installations regulated under the EU ETS, the most active accounts are classified as ‘non-regulated account type'.     

浅议地勘单位的特点

地勘单位大致分为传统地勘单位、现代地勘单位、一流地勘单位三个类别,传统地勘单位的特点是事业体制,计划任务,模式单一;当代地勘单位的特点是企事混合的体制,工作成果与矿权、项目紧密相连,多元化市场;一流地勘单位的特点是事企分开,拥有自己的矿山,经营方式多样化,利益最大化。
