我国将建成七大国家级石化产业园区,这些石化园区无一例外的位于沿海地区或海岛上,为此加强石化园区运营期海洋环境保护意义重大.环境影响后评估是运营期检验园区环境管理水平、查找园区环境问题的重要手段之一.目前,石化园区环境影响后评估主要以环境要素逐一分析法最为常见,而将石化园区作为一个整体从资源、环境、管理等角度综合评估的方法尚不多见.本研究在阐述我国海洋环境后评估和深入分析石化园区用海特点的基础上,结合PSR框架模型加以总结,提出了石化园区海洋环境影响后评估框架与指标体系,分为框架层、方案层和指标层,共25项考核指标,以期为今后沿海石化园区海洋环境管理研究提供思路.同时,本研究明确了各类评估指标赋值和权重等计算方案,并以大连某石化园区为案例进行了评估效果验证.  相似文献   

玉米深加工产业的循环经济模式研究     

王红  汤洁  王筠 《地理科学》2007,27(5):661-665

玉米深加工具有典型的替代能源及循环经济特征。目前玉米深加工行业面临的资源短缺和环境污染的双重制约。从促进经济与环境协调发展的角度,结合玉米深加工产业发展及环境治理现状,对玉米深加工产业的循环经济模式——玉米深加工生态产业园区建设进行了探索。通过对玉米深加工生态产业园上下游原料产业链的延伸、各环节废物的资源化分析、能源与水资源回收利用的设计和生态产业园区外围企业关系的研究,结果表明,通过实施清洁生产和延长产业链,构建闭合循环的玉米深加工生态产业链条,可实现资源、能源的有效节约和副产品、废弃物的综合利用,具有相应的环境、经济和社会效益,在增强企业绿色竞争力的同时可促进玉米深加工产业的可持续发展。该模式对吉林省及同类地区玉米深加工产业的可持续发展有指导和借鉴意义。  相似文献   

新疆森林公园的分布及旅游开发初探   总被引：1，自引：0，他引：1  

杨海英  阎顺  于生华 《干旱区地理》2007,30(1):156-162

新疆森林公园的分布以山地为主,平原为辅,主要集中在天山北坡和阿尔泰山;树种等资源在山地主要有雪岭云杉,新疆落叶松,新疆冷杉等针叶林,平原则主要以胡杨、灰杨等荒漠湖岸林为主,并分布着多种新疆特色的灌木,新疆森林公园起步较晚,但数量稳步增长,并已根据不同层次的需求,进行旅游开发建设,发展势头良好。通过对新疆森林公园的数量、级别、面积及建设时间等基本情况进行分析,进一步对新疆森林公园的现状及功效分析,得出进一步更好的发展森林公园的必要性。最后,提出抓住森林公园“天然养吧”等资源优势,结合龙头景区,因地制宜开发建设,并在开展旅游活动中突出地方特色,不断完善森林公园管理规范,实现资源永续利用的发展建议。  相似文献

From national to post-national territorial identities in Israel-Palestine     

David Newman 《GeoJournal》2001,53(3):235-246

Territory remains a central component of national identity in the contemporary political discourse between Israelis and Palestinians, both populations opposing power sharing within the same space, for fear of the other's domination. The contemporary political discourse relates to conflict management and the desire for separate spaces within which national identities are strengthened through territorial/national homogeneity. The Zionist national ideology of most Jewish citizens of Israel has strong territorial roots; hence they reject the post-Zionist post-nationalist ideology, regardless of whether they accept the possibility of change in Israel's territorial configuration or of a diminishment in the importance of the territorial dimension of national struggle. The rights of residency and citizenship even of second and third generation Jewish citizens remain linked with the territorial configurations of a State that will continue to be called Israel and have a national anthem expressing the aspirations of a single, exclusive, national group. But within territorial readjustment, issues of configuration may become less relevant and in it is this sense that post-Zionism focuses on a discourse of territorial pragmatism, rather than the disappearance of territory from the nationality-citizenship debate altogether. It is part of a process of re-territorialization and spatial reconfiguration of political and national identities, not a reversal of territorialization, if only because there is no such thing as a post-territorial notion of the organization of political power. The boundaries of national identity become more permeable, more inclusive, but they do not disappear altogether.  相似文献   

Ecological conflicts in Poland   总被引：1，自引：0，他引：1

Transformation of the political system, observed in Poland for 10 years in connection with economic restructuring and basic socio-economic reforms to harmonise with European Union structures, is also evident in terms of environmental management. Pollution has been reduced in many ways but the rise in living standards, linked with the rapid growth of cars and other forms of consumption, has had a negative effect and environmental conditions have deteriorated in the central areas of large cities. The growth of waste water and refuse is a considerable problem. More areas are now officially protected and the three levels of local government established at the beginning of January 1999 (voivodeship, district and community) all have certain defined environmental protection responsibilities which are cumulatively greater than before. Meanwhile there is a greater awareness in society of environmental issues, although it does not yet lead to a high level of participation in protection work. However, there are strongly-expressed opinions on the ecological acceptability of certain economic developments and conflicts are frequently arising within communities and local governments and also between investors on the one side and ecological organisations and environmental protection institutions on the other. Most controversial are new roads, power stations (like the Zarnowiec nuclear project) and reservoirs like the one on the Dunajec river at Czorsztyn. Local communities frequently resist plans for waste dumps, incinerating plants and other developments which are seen as injurious to health or the quality of life. The planned reprivatisation of the state-owned forests is also criticised by foresters and ecological movements. Conflicts are likely to grow as economic development accelerates but better information and greater public understanding of the need for sustainability should make for consensus. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献   

National territorial planning at the turn of the 21st century     

Yong-Woong Kim 《GeoJournal》2001,53(1):5-15

In the early stages of economic development in Korea, national territorial planning was used as a policy tool to guide spatial structure and to provide physical infrastructure for urban and industrial development. Such a top-down approach was inevitable because Korea maintained the centralized political and government system until the early 1990s. Circumstances, however, have changed recently since the 1990s with progress in democratization and localization. In addition, forces of globalization are making significant impacts on the parameters of national territorial planning. Reflecting these changes in both internal and external conditions, the Fourth National Territorial Plan (2000–2020) has adopted a different approach from the past three territorial plans. This paper reviews the socio-economic background that necessitated such changes in approaches to national territorial planning. A major thrust of the Fourth Plan, a focus on emergent or anticipated planning issues in Korea, is discussed. Finally, the paper examines the rationale for long-term strategic planning in the highly fluctuating situation facing Korean society in the new century.  相似文献   

中国沿海地区国民收入预测的新组合模型     

刘玉龙  陆大道 《地理科学》1996,16(4):305-311

着重讨论一种基于灰色ＧＭ（１，１）模型及国民收入决定函数模型而建立的新组合模型。该模型建模方法简单，组合性强，并且在各模型的拟合精度提高。该模型汲取了灰色ＧＭ（１，１）模型模拟国民收入变化趋势的优点和国民收入决定函数模型模拟国民收入波动的优点，使组合模型不但在趋势上符合国民收入的发展，而且也给出了在波动方面的比较一致的模拟。  相似文献
