Spatial distribution of ecological security status assessment of West-Liaohe River based on geographic information system

Eco-security assessment is a hot research area in resource and environmental science, which involves data with much spatial, non-linear, and random features. Geographic information system (GIS), as a useful tool to analyze and manage spatial information, has a superior advantage in this field. A case study in the western part of the Liaohe River featuring a method of eco-security spatial differences (ESSD) based on GIS is developed in this paper. The method includes four steps: 1) developing the pressure-state-response (P-S-R) framework with site data; 2) digitizing West-Liaohe River and setting its GRID database of ecosecurity assessment indicators; 3) figuring out the relative membership degree (RMD) of eco-security indicators by using the analytical hierarchy process with the weight of indicator; 4) classifying the security zone and mapping the assessment result of eco-security status in grid by GIS method of assigning and clustering. The visual spatial differences of eco-security based on GIS enables decision makers to know the status of eco-security better in making policies for achieving sustainability.     

埋地管道缺陷的自漏磁场计算方法研究

基于现有的埋地管道缺陷自漏磁场计算方法把缺陷处的磁荷假设为均匀分布,对于计算结果与实际检测存在较大误差的问题,通过采用ANSYS软件对管道缺陷进行有限元分析,根据材料力磁关系和磁荷理论,提出1种考虑磁荷实际分布的缺陷自漏磁场计算方法,并将该计算方法应用在某埋地管道磁记忆检测中。研究结果表明:该方法计算结果与实际值之间的峰值相对误差为6.9%,相对于现有方法16.4%的相对误差,准确度更高。研究结果有助于在管道磁记忆检测中,提高管道缺陷量化的准确性,对埋地管道缺陷非开挖识别与剩余寿命评价有重要意义。     

目前国有企业人力资源管理存在的问题与改进对策

目前国有企业在从传统人事管理向现代人力资源管理模式转变过程中遇到了改革受阻、效果不佳、观念落后、定位不高等问题,这些问题的产生主要是由于传统思想认识、落后的工作开发定位等根本性原因.因此,国有企业应采取树立新型大人力资源观念,加强人力资源管理部门自身建设,运用现代人力资源管理手段切实处理好培训开发、激励、评估等关键问题的改进对策.     

Industrial park management in the Chinese environment

In China many investments especially from foreign companies are located in industry parks. However, the general situation and management perspectives of developing Chinese industrial parks are not very clear to the westerners. With the rapid development, industrial parks will play a key role in China's economy, therefore, those issues relating with China's industrial parks need to be further discussed. This paper is one of such efforts. It will review the development of China's industrial parks, including characterizing industry parks in China and discussing the main site selection criteria and important aspects for foreign investors. The main focus of this paper is to discuss the current environmental management practices of industrial parks because such parks have been main sources of pollution. New development strategy for industrial parks, such as eco-industrial development, should be considered and implemented.     

阅读树木倾听自然

读书是学习,读树也是学习,是一种在户外感受自然、师法自然的学习,若能读出树的沧桑,听懂树的倾诉,那你的爱便是到了超凡脱俗的境界。 　　在北京麋鹿苑的户外生态教育活动中,有一个由二人进行的“读树”游戏,十分引人入胜。蒙面者在同伴的带领下,来到某棵大树前,通过用手触摸、用耳聆听、用心阅读,引发你对树木的亲和力,提高你对自然的感受力。做完游戏,你一定颇有感慨,那就请你一吐为快,与大家共享吧。 　　最近,美国自然教育家柯内尔来京教授了许多游戏,其中有一个叫“我的树”,是以人扮树,通过角色的转换,体验树的…     

Analysis on the Evolution of Regional Economic Disparity in the West Coast of the Strait

With the implementation of reform and opening-up, the overall economy of China has made brilliant achievements; meanwhile, however, the economic disparity has been enlarging among some regions, and between the city and the countryside. The existence and evolution of this kind of economic disparity is concerned with social stability, sustainable development and the construction of harmonious society, which has gradually become the hotspot in social economic development. The West Coast of the Strait （WCS） located in southeast littoral areas is adjacent to the Pearl and Yangtze River Delta in the south and north and faces Taiwan Province in the east. The stability and development of this region has vital political and economic meaning in the social economic development of our country. It has important theoretical meaning and practical value to research the form, characteristics and evolution of regional economic disparity in the WCS. Based on insightful analysis on existing study results on the WCS, the paper defines the connotation and extension. By a series of absolute and comparative relative evaluation indexes and taking the WCS since 1992 as the study object, the paper makes analysis on different scales including three regions, four regions, 20 cities and 152 counties, quantitatively evaluates the level, characteristics and evolution of the regional economic disparity and compares the regional economic disparity on different scales. The main conclusions are as follows： the variation trend of the absolute disparity of the whole region is obvious and stable, which has presented an inflating trend; the comparative variation trend on a large scale has waved, The comparative disparity of the three regions increased annually from 1992 to around 2000, which had a decreasing trend from around 2000 to 2005; the comparative variation trend on a small scale was not stable, which showed an annual increase of four regions, 20 cities and 152 counties from 1992 to around 2003 and a decrease from around 2003 to 2005; the
