Evaluating Management of Protected Areas: Integrating Planning and Evaluation

/ An approach to evaluating the effectiveness of management of protected areas is proposed. This approach has been used in developing an evaluation strategy for the Fraser Island World Heritage Area in Australia. The main component of the strategy is built upon the desired outcomes specified in the management plan for the area and thus provides a basis for assessing the extent to which the plan's objectives are being achieved. A series of monitoring programs have been proposed to enable this assessment. Examples of monitoring programs developed as part of the evaluation strategy are presented. A second component of the strategy monitors the implementation of the management plan. A management information system has been developed to record and report on the extent to which the specific actions specified in the management plan have been implemented. The strategy is discussed in relation to seven objectives set for the evaluation program in its design phase.KEY WORDS: Planning; Evaluation; Monitoring; Management; Protected areas     

An Integrated Model of Public Contact Planning for Conservation Management

/ Public contact is a vital component of any program to manage natural resources. A well-planned public contact program uses a variety of strategies to create a sympathetic and environmentally aware public and to meet specific management-related objectives. A methodology is proposed that can be applied to planning public contact at any level, from media design for a specific project to corporate strategies for communication. The methodology integrates management-driven, client-driven and resource-driven planning to provide the connections essential to effective communication.KEY WORDS: Planning; Public contact; Interpretation; Conservation; Management     

Does Decentralization Matter in Environmental Management?

/ Questionnaires from 39 state National Pollutant Discharge Elimination System (NPDES) agencies were analyzed using principal component analysis and multiple regression. Decentralized programs scored better in a fundamental indicator of efficiency (lower percentage of expired permits) and in the key effectiveness measure of unit-cost compliance achieved. In no case did centralized states score significantly better than decentralized ones. These results indicated support for the theory that superior local knowledge is the key mechanism. Case studies of five states suggested internal program adjustments may cause outcomes to converge towards efficiency and effectiveness, perhaps explaining the large number of variables showing no difference between centralized programs and decentralized ones.KEY WORDS: NPDES; Compliance; Decentralization; Outcome; Efficiency; Unit-cost analysis

GPS/GSM/GIS海上溢油跟踪监测系统的研究

在车载GPS监控系统的基础E研究开发了一种漂浮移动性能与溢油相似的、并具有GPS接收和发送功能的GPS浮标。在溢油事故发生后立即将其投放存厚油膜层中随油膜一起漂移。监测中心通过GSM移动通信网实时接收GPS浮标发出的定位信息，并应用地理信息系统技术实现对溢油位置、漂移速度、轨迹、方向的实时跟踪和信息显示．从而为溢油应急指挥提供一种准确实时、成本低廉、全天候的溢油全程监测手段。     

安徽霍邱李老庄铁矿-菱镁矿床地质特征及成因类型

霍邱铁矿田位于华北地台南缘,处于北淮阳山字型构造脊柱部位。李老庄铁矿—菱镁矿床置于霍邱铁矿田中部。该矿床主要产于上太古界霍邱群变质岩系中,矿体赋存于富镁碳酸盐中,矿石类型可以分为菱镁矿磁铁矿石和蛇纹石磁铁矿石,各占25%。成矿物质来源于这些变质岩系的多层、分散的含铁建造矿源层中。依据矿床地质特征,结合矿石同位素地质和测年结果,李老庄铁矿—菱镁矿铁矿床是晚太古代海相火山—沉积变质型矿床。     

海水水质评价的物元分析法

为了探索物元分析方法用于海水水质综合评价的可能性，通过计算海不水质对各评论评价等级的综合关联度，进行海水水质综合评价。用物元分析法对５个监测站位的海水水质进行评价，结果表明它用于海水水质综合评价是可行的。     

对排海污染物实行“纳污区”管理探讨

我国近海是经济增长和发展最重要和最集中的区域。然而,随着沿海工业的发展,大量未经处理的陆源污染物随间排海,沿岸水域形成“黑潮”、“赤潮”致使我国近海海域污染加剧,生态平衡失调,严重影响了海域资源环境的可持续发展。     

赣闽浙三省接合区砂金资源的分布与沉积学特点

赣闽浙三省接合区砂金资源分布广泛,尤以赣东北乐安江、昌江水系最富。本文是在对该区野外调查,取样分析和典型砂金矿床、矿点地质环境分析的基础上,认为冲积型砂金富集与矿源层分布,水系发育规模及地貌条件,含金物质搬运距离,水动力条件,沉积界面微地貌及合金物质沉积后埋藏状况有密切关系,掌握砂金沉积学特点有利于资源的勘探和开发。
