Differing from conventional tourism, glacier tour- ism has its special characters while there is little literature on it. It is of great significance to study its characters and seek after the harmonious development in exploitation and protection of glacier tourism resources. Glacier tourism refe…  相似文献   

TREE INVASION IN MEADOWS OF LASSEN VOLCANIC NATIONAL PARK,CALIFORNIA*     

Alan H. Taylor 《The Professional geographer》1990,42(4):457-470

The causes of tree invasion into meadows in Lassen Volcanic National Park were investigated by dating invasive trees and associating age structure patterns with regional variations in fire history, grazing, and climate change. Massive invasion was associated primarily with cessation of livestock grazing and burning between 1905 and 1933, but climatic change may also have contributed. Maintenance of meadows may require continued use of unnatural processes due to uncertainties about pre-European fire regimes and other resource considerations.  相似文献   

USERS′ PERCEPTION OF KOWLOON PARK, HONG KONG： VISITING PATTERNS AND SCENIC ASPECTS   总被引：1，自引：0，他引：1

Hong Kong is a hyper-dense city with 7×10⁶ people living in an area of 1100km². One way to improve the livability of compacted and congested cities like Hong Kong is through the provision of urban parks, an aspect that has largely been under-researched. This study focuses on how users perceive and utilize various facilities in the Kowloon Park. The findings revealed that the Kowloon Park is one of the most preferred parks in Hong Kong for both local residents and tourists. Users were quite satisfied with the park’s facilities. Notably, the most important component of an urban park is its greenery. This is followed by water elements, seating places, and facilities for various recreational activities. The improvements users would like to see in urban parks include good design and management, meeting users’ needs, overcoming barriers to use, and providing a high quality and varied experience for different groups in the community. The findings of this study provide a good basis to address park management issues from the users’ perspective. In particular, parks should provide easy access, encourage optimum usage and enable complimentary improvements to the environment.

基于PSR模型的石化园区海洋环境影响后评估指标体系研究          下载免费PDF全文

赵素芳  袁仲杰  姚翔  王薇 《应用海洋学学报》2018,37(3):404-412

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

资源环境安全问题始终是世界各国持续发展的核心任务和基本需求。考虑到单要素和整体两大分析方法的不足 ,作者提出了一种具有针对性的要素综合分析方法。根据世界 10个人口 1亿以上国家的抽样分析表明 ,土地、水资源、矿产及生态环境的整体状态是决定国家资源环境安全的基本要素群体。与此同时 ,为了改善国家 ,特别是发展中国家的资源环境脆弱状态和提高其稳定程度 ,第一是严格控制人口增长 ;第二是努力推进本国资源环境开发的国际化进程 ;第三是增大智力投入以提高资源深化加工程度 ;第四是加大本国生态环境保护力度。  相似文献   

The Asian Economic “Flu”: A Geography of Crisis     

Jessie P.H. Poon  Martin Perry 《The Professional geographer》1999,51(2):184-196

This paper examines the recent economic turmoil in East Asia which has been linked to the convulsive nature of global capital movements. East Asia, once the site of rapid capital accumulation, lost its economic momentum beginning in July 1997 with a series of currency devaluations, culminating in a net outflow of private capital within a year. International capital's ability to disembed the region, however, has been highly uneven over space. That China, Hong Kong, Singapore, and Taiwan are far more territorially resilient while others like Indonesia, Thailand, and South Korea initiated major political changes suggests that the geography of crisis is far more complex than is currently presented.  相似文献
