基于绿色经济理论,提出生态工业园区绿色发展水平的内涵.从经济发展、生态环境保护、生态工业链建设及绿色管理4个方面综合考虑,建立了生态工业园区绿色发展综合评价指标体系.以福州经济技术开发区为例,利用熵权系数法客观地确定指标权重.利用综合指数法进行园区绿色发展水平综合评价,从中识别和分析开发区在“十一五”期间经济发展、环境保护、管理等方面存在的问题,并给予针对性建议.  相似文献

以绿色经济理论为基础,采用生态工业园区绿色发展水平评价指标体系,结合福州经济技术开发区"十一五"期间绿色发展水平的相关研究成果,并利用灰色系统理论对开发区"十二五"期间的绿色发展水平进行动态预测分析.结果表明:指标预测值与实际值整体变化趋势相似,"十二五"时期绿色发展水平总体上保持良好的发展态势.结合开发区发展实际情况,认为经济利益、资源与生态环境、企业共生水平建立、政策与制度的制定、科技创新是生态工业园区绿色发展的驱动力所在.  相似文献

<正>从20世纪60年代美国经济学家鲍尔丁提出的"宇宙飞船理论"到如今的绿色生产、循环经济生态园区建设,可持续发展的研究和实践就在一直不断地深入进行着。随着社会对可持续发展的重视,在我国也开始建立以循环经济理论为依据的各种各样的生态工业园区。它以清洁生产为前提,从源头防治污染产生开始,在园区内部把不同的企业连接起来形成共享资源和互换产品的产业共生组合。彻底摈弃了经济发展与环境保护相互割裂、"先污染、后治理"的传统工业增长模式。  相似文献

生态现代化     
随着我国社会经济的快速发展,环境保护与经济发展的矛盾日益凸现,绿色家园、绿色地球的呼声越来越高,寻求一种环境与经济双赢的新模式成了现代人的共同愿望。以“生态现代化”为主题的《中国现代化报告2007》一经公布,立刻激起了社会各界广泛的关注。“生态现代化”逐渐走进人们的视线,成为世人关注的焦点,人们似乎从这种新模式中看到了巨大的魅力和潜力。其实,生态现代化建设在我国已有30多年的历史,但中国仍属于世界较低水平。生态现代化建设是整体现代化必不可少的组成部分和价值追求目标,是现代化发展到了一个高级阶段的体现和表证,是保证一个国家、一个区域、一个城市可持续发展的强大动力。以苏州、无锡、常州为代表的苏南地区是全国经济发展较快的区域之一。近年来,这些城市坚持“环保优先”理念,实施可持续发展战略,出现经济增长与环境质量同步发展的良好状态。与此同时,苏北地区的许多城市摒弃“先污染后治理,边治理边污染”的发展模式,通过一系列行之有效的举措,在加快工业经济发展的同时,城乡生态面貌得到大大改善。江苏在协调经济发展与环境保护方面作出了表率。本期“特别关注”栏目,带你走进“生态现代化”,解读2007年《中国现代化报告》,同时刊登了《如何建设可持续发展的现代化生态城市》、《苏南环境向好提前出现拐点》和《射阳精心打造绿色环保家园》等文章,以飨读者。  相似文献

为了探索江西省开发区土地集约利用对区域生态效应的影响,采用数据包络分析法(DEA),建立了江西省开发区土地集约利用区域生态效应评价模型,分析了全省11个地级市开发区土地集约利用投入与区域生态环境产出之间的关系。研究结果表明,江西省开发区土地集约利用水平对区域生态环境的有效性影响较大,2013-2017年间,只有景德镇市、宜春市和吉安市开发区土地利用现状和土地利用效益对当地生态环境产生积极影响,大部分开发区土地开发建设未能与区域生态环境保护形成有效联动;江西省开发区土地集约利生态效应区域差异明显,2013年开发区土地集约利用对区域生态环境更为有效的地区集中在赣西北,2017年向赣东、赣南集中;作为江西省经济发展水平较高的南昌市、九江市和赣州市,其DEA有效值均不高,开发区土地集约利用水平与当地区域生态环境保护不相适应,土地集约利用投入与区域生态环境产出不协调。  相似文献

【目的】核算重庆市生态GDP,评估经济增长GDP中资源环境的消耗成本和生态收益,以期将生态理念植入社会经济发展,为经济高质量发展政策的制定提供一定参考。【方法】采用能值分析法和生态服务单位面积价值当量表分别核算资源环境损害价值和生态服务价值,进而从GDP中减去资源环境损害价值再加上生态服务价值后剩余的GDP即为生态GDP,并将重庆市“九五”、“十五”、“十一五”及“十二五”4个规划期的生态GDP与绿色GDP、GDP进行对比分析。【结果】1)资源耗减和环境损害价值从84亿美元增至1419亿美元,资源耗减价值增长明显;2)生态服务价值从490亿美元增长至772亿美元,生态服务价值增长相对较缓慢;3)生态GDP从589亿美元增至1862亿美元。“九五”时期和“十五”时期生态GDP最大,GDP次之,绿色GDP最小;“十一五”时期和“十二五”时期GDP最大,生态GDP次之,绿色GDP最小。【结论】直辖以来重庆市经济持续增长但同时自然资源和生态环境的“透支”较大,即使在得益于一系列生态文明建设政策举措后生态服务价值持续提升下,也难以抵消资源环境损害价值,因此经济高质量发展不仅要加快生态文明建设,也要注重资源高效低耗利用。

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3~4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰~ -7.8‰, PDB) and matrix dolomites (-6.6‰~ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084~0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078~0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.  相似文献

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。  相似文献

The explosive growth of the Internet and database applications has driven database to be more scalable and available, and able to support on-line scaling without interrupting service. To support more client's queries without downtime and degrading the response time, more nodes have to be scaled up while the database is running. This paper presents the overview of scalable and available database that satisfies the above characteristics. And we propose a novel on-line scaling method. Our method improves the existing on-line scaling method for fast response time and higher throughputs. Our proposed method reduces unnecessary network use, i.e. , we decrease the number of data copy by reusing the backup data. Also, our on-line scaling operation can be processed parallel by selecting adequate nodes as new node. Our performance study shows that our method results in significant reduction in data copy time.  相似文献

R-Tree is a good structure for spatial searching. But in this indexing structure,either the sequence of nodes in the same level or sequence of traveling these nodes when queries are made is random. Since the possibility that the object appears in different MBR which have the same parents node is different, if we make the subnode who has the most possibility be traveled first, the time cost will be decreased in most of the cases. In some case, the possibility of a point belong to a rectangle will shows direct proportion with the size of the rectangle. But this conclusion is based on an assumption that the objects are symmetrically distributing in the area and this assumption is not always coming into existence. Now we found a more direct parameter to scale the possibility and made a little change on the structure of R-tree, to increase the possibility of founding the satisfying answer in the front sub trees. We names this structure probability based arranged R-tree (PBAR-tree).  相似文献

The geographic information service is enabled by the advancements in general Web service technology and the focused efforts of the OGC in defining XML-based Web GIS service. Based on these models, this paper addresses the issue of services chaining,the process of combining or pipelining results from several interoperable GIS Web Services to create a customized solution. This paper presents a mediated chaining architecture in which a specific service takes responsibility for performing the process that describes a service chain. We designed the Spatial Information Process Language (SIPL) for dynamic modeling and describing the service chain, also a prototype of the Spatial Information Process Execution Engine (SIPEE) is implemented for executing processes written in SIPL. Discussion of measures to improve the functionality and performance of such system will be included.  相似文献

Advances in wireless technologies and positioning technologies and spread of wireless devices, an interest in LBS (Location Based Service) is arising. To provide location based service, tracking data should have been stored in moving object database management system (called MODBMS) with proper policies and managed efficiently. So the methods which acquire the location information at regular time intervals then, store and manage have been studied. In this paper, we suggest tracking data management techniques using topology that is corresponding to the moving path of moving object. In our techniques, we update the MODBMS when moving object arrived at a street intersection or a curved road which is represented as the node in topology and predict the location at past and future with attribute of topology and linear function. In this technique, location data that are corresponding to the node in topology are stored, thus reduce the number of update and amount of data. Also in case predicting the location,because topology are used as well as existing location information, accuracy for prediction is increased than applying linear function or spline function.  相似文献
