采用元素相关性分析方法，找出浦东新区大气气溶胶中碳颗粒的污染源，确证该区大气中碳颗粒主要来自煤的燃烧。同时初步找出浦东新区大气中碳颗粒污染的时空分布和粒径分布规律，为改善浦东 新区大气污染状况提供依据。     

森林火险的序贯分析初探

本文利用森林着火危险度指标属于正态分布的特点,根据正态型序贯分析的原理,提出了确定林火危险性的序贯分析方法;建立了长白山林区5个站点森林火险的“安全域”与“危险域”的模型;并以东岗(长白山西坡)为例,作了正态型序贯分析全过程的应用示例。结果证明,利用正态型序贯分析来确定林火的等级是可行的、可靠的,具有实用价值。     

People's Perception About Participatory Developmental Programs: Lessons from the Mountain Risk Engineering Program in the Indian Central Himalaya

The Indian Himalayan Region (IHR) is suffering from environmental degradation due to population pressure and infra-structural needs. This is coupled with a natural setting, which creates problems of accelerated soil erosion and mass wasting. In view of these environmental difficulties and the growing concern for effective restoration, there has become an urgent need for multi-disciplinary coordinated improvement schemes. The mitigation of risk arising from hazardous mass wasting processes, through a careful and systematic approach, has helped in the development of the concept of Mountain Risk Engineering (MRE). The MRE practices involve an integrated approach to solving the infra-structural engineering problems of hilly and mountainous areas through environmentally conscious cost-effective and site-specific designs. However, the role of people's participation is extremely crucial for the success of such programs. This paper analyzes the perception of the local people about the approaches adopted in MRE participatory developmental programs and throws light on the intricacies of peoples' participation.     

池州国家级生态经济示范区生态系统价值的计算

利用Mark·T·Brown的自然资本能值法和Costanza的生态系统效益价值法,从经济角度分别计算了池州生态经济示范区的生态系统的资本价值和效益价值,得出该示范区生态资本可达7899亿美元,其中缓慢可更新生态资本和不可更新资本分别占24 8%和75 2%,是2001年本地区GDP值的1000倍;生态效益价值达192 3亿元人民币,是2001年本地区GDP的3 1倍,生态系统对环境贡献率大。通过价值计算进一步论证了池州生态经济示范区的生态示范作用,为充分合理地发挥生态系统效益促进经济与自然协调发展提供科学依据。     

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     

三峡库区降雨径流水体中铜、锰、镍、锌、铅含量及分布特征

本文按时段和随机采集了三峡库区降雨径流水体样品，测定了水体中Ｃｕ、Ｍｎ、Ｎｉ、Ｚｎ、Ｐｂ含量，统计结果表明：Ｍｎ、Ｚｎ、Ｐｂ在径流水体中的含量趋于平均，变异系数较小。随产流时间的变化，水体中５种元素的变化规律不明显     

山岳型宗教旅游地的土地利用分析--九华山风景名胜区实证研究

九华山风景名胜区是山岳型宗教旅游地。通过对九华山风景区的实地调查，总结了该类旅游地的土地利用特点，即统一性和协调性、难以变更性、总量有限性，并进行了土地利用沿革、变更和影响方面的分析。利用层次分析法从生存指标、发展指标、社会指标、环境指标和智力指标5个方面对九华山风景区的土地利用进行了定量讨论，认为九华山风景区土地利用问题现阶段主要集中在九华街景区、花台景区和柯村景区。在此基础上，对九华山风景区土地的可持续利用提出了相应的对策。     

主题旅游活动项目策划研究--以峨眉山"2004年百姓生活游"旅游活动项目策划为例

自1992年以来，我国国家旅游局每年推出一个专项旅游产品作为对外宣传口号。为配合此项活动的开展，各地纷纷组织了相应的主题旅游活动。通过主题旅游活动的开展，能够有效地整合区域旅游资源、提升旅游目的地形象、丰富旅游目的地产品类型、促进旅游基础设施和服务设施建设、弘扬当地传统文化。通过对峨眉山“2004年百姓生活游”主题旅游活动项目策划的研究，对主题旅游活动项目策划的理论与方法进行了初步探讨。
