环渤海湾海洋资源环境承载力定量研究

环渤海湾地区经济发展迅速但开发利用过度,生态问题突出。本文以社会环境学理论、系统论、可持续发展理论等为基础,建立了环渤海湾海洋资源环境承载力评价指标体系,利用单项评价法,以地级市为基本单位对环渤海湾地区的海洋资源环境承载力进行评价。结果表明滨州市的海洋资源环境承载力较好,其次为唐山市和天津市,沧州市的海洋资源环境承载力较弱。     

Dysfunctions in common fishing regulations

One of the main concerns of the Common Fisheries Policy (CFP) lies in guaranteeing consistency among the different implemented actions. The main concern is establishing a relationship between the levels of compliance with the Multi-annual Guidance Programme (MAGP), the adoption of total allowable catches (TACs), and the levels of compliance with rules by producers.     

Understanding marine ecosystem based management: A literature review

Ecosystem based management takes into account the interconnectedness and interdependent nature of ecosystem components and emphasizes the importance of ecosystem structures and functions which provide a range of services. The concept has now been adopted by many international agreements and national governments and is in the process of being implemented. This paper seeks to review the literature and to analyze the understanding of the subject. The term is defined and its implementation in fisheries and for all marine uses is analyzed. It has been concluded that to understand marine ecosystem based management one must consider ecosystems as complex adaptive systems which can show changes at higher levels from actions and processes occurring at lower levels. Recognizing that humans are part of these complex adaptive systems is vital in that their actions along with other processes can lead to transformations in ecosystem functioning. This recognition is also important to show how society can sustainably exploit these resources and that the inclusion of all stakeholders in the management process is necessary to legitimize the process. The uses of the precautionary principle along with adaptive management are seen to be useful tools in implementing these insights into the management of natural resources. Finally, the need for reducing consumption of fish is considered.     

中国地震台网各类前兆手段地震监测能力的评价

利用1988～2005年18年间全国会商会所提出的各类定点前兆异常,研究其与下一年(1989～2006年)大陆地震的对应关系,从414次地震资料的统计中得出,除地下水位和地磁外,其它5种前兆观测手段在有震区的异常比均低于无震区或全大陆的异常比,但各手段综合异常比在有震区要高于无震区。遵照"地震监测能力好的前兆手段,在其监测范围内,有震时应有较高的异常比,无震时应有较低的异常比"的原则,我们认为地磁和地下水位是比较好的前兆观测方法。

网络计划管理技术在长江某穿越隧道工程中的应用

网络计划技术是一种科学的计划管理技术，它对工程组织过程和项目实施步骤进行全面的规划、编排，并在工程项目实施初期对多种方案进入深入的研究与比较，更科学地进行目标进度的安排。本文以长江某穿越隧道工程为例，详细探讨了用网络计划技术进行工程管理的过程。     

福建省矿产资源潜力的地球化学预测

利用区域化探归面（水系沉积物测量）资料，使用区域浓度克拉克值及变化系数两个参数，对福建省32种元素的资源潜力进行了排序，认为在目前国家的导向矿种中，福建省的资源潜力依次为锌－银－铅－锡－金－铜－钼。同时根据谢学锦院士提出的地球化学块体学块体的理论和方法，预测了政和Au地球化学块体、龙岩中甲Cu地球化学块体、大田Pb地球化学块体的资源潜力，分别为金430吨、铜625万吨、铅408万吨。初步探讨了成矿系统的元素分带及地球化学模式研究的意义和方法，认为这项研究对上述地区的打矿突破具有重要作用。     

岷江上游土地资源适宜性评价研究

岷江上游地区的可持续发展直接影响着四川省社会经济的发展，以岷江上游土地资源适宜性评价为研究对象，利用地理信息系统（GIS）技术，建立了该地区的土地资源基础信息库；利用面向对象编程技术，应用模糊集合综合评价法及对各土地适宜性监介指标确定和适宜性等级的划分进行了岷江上游土地资源适宜性评价，并提出了土地利用规划及今后改造利用的方向。
