大庆红岗生态工业园区创建的现有条件

生态工业园是根据循环经济理念和工业生态学原理而设计建立的一种新型工业组织形态,在园区内通过废物交换、循环利用、清洁生产等手段,实现资源利用的最大化和废物排放的最小化.文章通过对大庆市石油、石油化工产业链现状分析及产品代谢和废物代谢分析,说明大庆红岗具有创建生态工业园区的区位和资源优势,园区所在区域内现已经初步形成了石油开采、石油化工、轻烃加工和化工建材产业(品)代谢连及废油、废水回注等废物代谢链的生态工业雏形,为创建大庆红岗生态工业(石化)示范园区奠定了一定的基础.     

上海市工业区环境管理问题与对策浅析

在对上海市78家工业区进行抽样调查的基础上，分析了工业区环境管理目前存在的法规缺位，机构不健全，基础设施不健全、环评和规划实施不全面、信息沟通不畅、考核机制待改进等主要问题。并提出了加快环境管理法制建设、建立健全环境管理机构．建设和完善区域环境基础设施、全面实施区域环评和环保规划、加强与地方环保行政部门的信息沟通、建立完善环境监督和考核制度等对策和建议。     

两种共生模式之比较

State Park Directors' Perceptions of Mountain Biking

/ This study intended to explore the perceptions of mountain bikingmanagement through a mail survey of state park directors in all 50 states.With a 100% response rate, it was found that 47 states permit mountainbiking in their state parks, however, few state parks have formalized plansto manage this outdoor activity. The management policies that do exist arenot followed on a statewide basis but vary within each state and at eachstate park. Many states have worked cooperatively with local mountain bikingclubs to develop and maintain mountain bike trails, promote rider education,and provide volunteer patrols on trails. The issue of user conflict surfacedwith almost three-fourths of the managers responding that conflict existedbetween mountain bikers and other trail users. This preliminary study shouldprompt further research with on-site managers focusing on the use ofmanagement plans for mountain biking, cooperation between managers and usergroups, and user conflict. It is recommended that an Internet-basedinformation clearinghouse or discussion group be made available to landmanagers by a national bicycling organization.KEY WORDS: Mountain biking; State parks; State park directors;Recreation resource management     

SOUND POLICY OR SMOKE AND MIRRORS: DOES ECOSYSTEM MANAGEMENT MAKE SENSE?1

ABSTRACT: Protection of ecosystems as entities on the landscape has attracted a wide range of support. Ecosystem-based public policies are claimed to be more effective, efficient, and scientifically sound than other approaches to environmental and natural resource policy. The ecosystem concept was never intended to serve as a public policy guide or to determine landscape units for land management purposes. This paper critically examines the use of the ecosystem concept in public policy and land use management and analyzes the proposed rule to manage the National Forest System according to ecosystem management principles. The concept is found to be unsuitable as a basis for guiding environmental and natural resource public policies in general while the proposed rule to manage the national forests according to ecosystem management principles is shown to be incoherent.     

城市绿地系统建设与城市减灾防灾

自然灾害往往给城市造成重大损失.在城市综合防灾减灾体系中,城市绿地系统占有十分重要的位置.城市绿地系统是城市规划和建设中的重要组成部分,它不仅具有美化城市环境、净化空气、平衡城市生态系统、为城市居民提供休憩游乐场所等作用,同时还具有防震、防火、防洪、减轻灾害的功能.从城市绿地的定义和分类人手,分析了城市绿地系统在城市综合防灾减灾中的作用,并通过介绍和分析日本防灾公园的规划建设,探讨了城市避灾绿地系统的规划方法.     

开放型历史文化名城主题公园的建设

长期以来,历史文化名城的保护工作受到以商住房地产开发为主要形式、"投资者主导型"为开发模式的旧城改造浪潮的冲击.历史文化名城主题公园以保护古城风貌、延续城市历史文脉为宗旨,运用主题公园的规划设计、经营管理等方法和开发模式,以保留、修复、移植和改造古城建筑为技术手段,建设成为集名城风貌观光、史籍博览、特色商品购物、民俗文化娱乐为一体的旅游目的地,从而达到保护历史古城风貌,树立文化名城形象的目的.     

层次分析法在工业园区生态影响评价中的应用--攀枝花市高耗能工业园区生态环境影响探讨

目前生态影响评价研究中的评价对象、内容和方法缺乏统一的模式，本文以攀枝花高耗能园区的开发为例，尝试建立一套系统的工业园区开发生态影响评价方法，该方法以层次分析法为基础，将生态系统分解为经济发展、社会进步、环境保护、景观生态保护四个目标子系统，并在此基础上细化评价因子，通过专家打分和矩阵运算确定其权重，再根据适当的评价标准，运用指数法得出评价结果。结果表明该工业园区在建成前后，其生态综合指数由0．552提高到0．794．其级别由三级提高到二级，说明该园区生态系统总的状态得到改善，该工业园区项目开发可行。     

Improving Operational Planning and Management of National Parks in Turkey: A Case Study

The purpose this study was to improve operational planning and management of national parks in Turkey to balance conservation use and sustainable management. Souksu National Park (SNP) was chosen as the study area. The data were obtained from interviews of 182 visitor groups (in total, 819 people) and analyzed using correlation, factor, discriminant, and regression analyses. It was found that the most important factors affecting operational planning and management of SNP are (1) travel cost, (2) visitor welfare level, (3) intensity of use, (4) size of visitor group, (5) type of recreational demand. The main source of visitors to SNP is from a zone within a 0–90-km radius. This region comprised 53.85% of total visitors to the park. The capital of Turkey (Ankara) is the most important source of visitors from within this zone. The optimum activity mix in SNP is also determined. Picnicking, viewing the scenery, and nature walks or trekking comprised the main uses of the park. It is anticipated that these findings will help to improve operational planning and sustainable management of the national park and the environment.
