基于价值取向的城市森林游憩服务需求研究

在调查南京城市森林游憩者的基础上,以森林价值取向为预测变量,对城市森林游憩服务需求进行了研究.研究表明,市民的森林价值取向包括生态取向、健康取向、文化取向、产品取向和消极取向五种类型;城市森林游憩服务需求则包括基本需求、拓展需求和个性需求三个层次.通过典型相关分析发现,对森林资源持“健康”、“文化”和“生态”价值取向的市民对森林游憩的“基本服务”需求明显,更重视森林的自然和文化环境保护;而持有“产品”和“消极”取向的市民,则希望森林游憩地能提供更多“拓展”和“个性”服务.在此基础上,提出了积极引导城市森林游憩者的政策建议.     

景区建设对区域经济发展的响应格局演变——以江苏省为例

论文以江苏省为例,构建旅游景区建设对区域经济发展的响应指数,在研究景区格局演变的基础上,运用空间变差函数分析响应的空间差异,并探讨了景区建设对区域经济发展响应的空间格局、演变过程,结果表明：江苏省旅游景区分布呈现出南多北少的格局,内部差异巨大;高响应区域单元数量明显增加,且主要分布在长江沿岸地区;响应格局在全方向上的均质性较好,但在各个方向上的差异切换较快。根据响应指数的差异和经济发展水平的不同,将所有单元划分为6 种类型。在上述分析的基础上,将影响因素分为表征层面的影响因素和内在层面的影响因素,并分析了各个因素的作用机制,据此提出不同类型单元的调控措施。     

WATER QUALITY IN MOUNTAIN RECREATIONAL AREAS1

ABSTRACT: Several seasons of water quality study in the eastern Sierra Nevada have provided much useful information. One study element focused in detail on a representative drainage: Bishop Creek, from sampled locations at 12,800 feet to the Owens River at 4,000 feet. Sub-studies ranged from geohydrology, through chemical and bacterial quality, to benthic ecology. A coordinated study also was made of spatial patterns of use. A second element focused on non-point source monitoring the length of the Inyo National Forest. From physical, chemical, and bacterial standpoints, water quality is generally very good. Strains of pathogenic bacteria have been confirmed, and substantial further work to establish the importance of their presence is needed. Recreational use survey results have been analyzed to produce a methodology permitting management of the resource as needed. In addition, basic policy recommendations to easily minimize risk have been developed.     

人工湿地的生态休闲利用与设计

人工湿地系统除了可以起到净化污水的作用,在经过精心设计后,还可发挥与自然湿地系统同样的生态保护功能,更可为人们提供一个休闲娱乐、旅游观光、科教科研的场所,越来越多的人工湿地系统开始重视并采用一系列的设计手段以充分发挥其自然价值和社会价值。本文详细地介绍了目前人工湿地综合利用研究进展,分析了综合利用时一些潜在的问题,及其设计时应当加以考虑的注意事项和建议。     

VISITOR VALUES AND LOCAL ECONOMIC IMPACTS OF RIPARIAN HABITAT PRESERVATION: CALIFORNIA'S KERN RIVER PRESERVE1

ABSTRACT: Preservation of the few remaining ecologically vital riparian areas in the southwestern United States is a significant policy concern. This article reports on two economic aspects of preserving a nationally renowned riparian birding area in Southern California. First, the article examines visitor willingness to pay (WTP) for habitat restoration and estimates an annual WTP of US $77 per visitor to preserve the habitat, about a half‐million dollars a year for estimated visitor numbers in 2000 and 2001. Second, it documents visitor expenditures in the local economy to be approximately three‐quarters of a million dollars per year. This direct visitor spending attributable to the riparian habitat generates around US $1.3 million in increased local business activity in this relatively remote rural area.     

Common access tradition and wilderness management in Norway: A paradox for managers

Many European countries, including Norway, have a right of common access tradition toward wildland areas for recreational activity. The “right of any one to move freely over all wildlands except farm fields and gardens” can serve as a paradoxical barrier to managing wildland areas and users for outdoor recreation. This article discusses the apparent paradox between free access and management of wildland recreation, the underlying principles of both concepts, and proposes an integrative basis for how the two concepts can serve the same major goal—freedom of access and use of wildland recreation areas without disturbance to other users or the resource base. A Norwegian field study is presented with campfire data and management strategies to illustrate the integrative nature of common access and wilderness management principles for the managing of wildland recreation opportunities.     

THE RESTON (VIRGINIA) LAKE-USE SURVEY: PUBLIC PERCEPTIONS AND MANAGEMENT IMPLICATIONS1

ABSTRACT: A public attitude survey was developed by a citizen committee and mailed to all residences (14,747) in the planned, suburban community of Reston, Virginia, which is responsible for maintaining four small, recreational impoundments. Over 18 percent of survey forms were returned, and characteristics of the survey sample suggest that the suite of respondents was representative of the Reston community as a whole. Of those respondents indicating a preferred lake use, 48 percent chose walking or looking as most important; boating as second at 27 percent; and fishing was third, favored by only 8 percent. Citizens feel strongly (94 percent) that the lakes are valuable community assets. Appearance was the characteristic most valued by 62 percent of respondents, and 58 percent considered degradation of water quality either the first or second most important ecological issue affecting local lakes. These findings provide a decisive public mandate for lake management activities related to visual quality. In response to this survey, the Reston Association, a homeowners' organization responsible for the lakes, increased public access of visual enjoyment, intensified litter control, expanded activities in public education on lake management and ecology, and continued a long-term program of water quality monitoring.     

ENVIRONMENTAL THRESHOLD FUNCTIONS FOR USER ORIENTED RESOURCE PLANNING AND MANAGEMENT1

ABSTRACT: Managers of water related outdoor recreation resources want to provide facilities and recreational opportunities of high quality that are attractive to recreationists. The reported research develops a relevant site quality assessment and measurement procedure called environmental threshold modeling. This modeling procedure is based upon the idea that individuals (i.e., recreationists) have specific, identifiable evaluative criteria which can be expressed as a mathematical function of various site characteristics. The function of interest is called a threshold function because it separates acceptable recreational settings from unacceptable settings. Individual specific threshold functions can be easily aggregated to form a population specific threshold function that estimates the proportion of a population that would find the recreational setting acceptable for some specific activity. Presented in this paper are illustrative calibration results based upon survey data collected from recreational canoeists using the Pine River in Michigan's Manistee National Forest.     

A METHODOLOGY FOR OUTDOOR RECREATION ANALYSIS IN A STATE WATER RESOURCES PLANNING STUDY1

ABSTRACT: The paper presents a methodology for outdoor recreation analysis in a comprehensive State water resources planning study. This methodology applies to determination of recreation participation desires among the population, allocation of those desires to areas of potential resources within which they must be satisfied, comparison of the areal potential resources against the allocated desires to identify areas having recreational resource deficits or needs, and exploration of alternative solutions to the identified needs. Major elements discussed are: market area, inflow-outflow, resource desire determination and projection, resource desire allocation, facility inventory, resource desire-resource analysis and alternative solutions to identified needs of water-oriented outdoor recreation.     

WATER QUALITY PERCEPTION BY USERS: CAN IT SUPPLEMENT OBJECTIVE WATER QUALITY MEASURES?1

ABSTRACT: Personal interviews were conducted with eighty campers in each of three Minnesota state parks to investigate the water quality perception of the recreationist. At the same time, water quality factors were measured or observed as an indication of conditions experienced by the interviewees. Most respondents perceived water pollution strictly on a visual basis. Sewage, public carelessness, industry, and farm fertilizers were “first choice selections” among major causes of water pollution in Minnesota. Seventy percent felt their recreational activities did not contribute to water pollution. Sixty-two percent said their life had not been affected by water pollution, while over two-thirds of the remaining thirty-eight percent listed curtailment of recreation as the primary result. Many mentioned an algal bloom at one park and the strong odor of rotten fish at a second park. On the basis of the senior author's observations, supported by the measurements taken, it was concluded that thèk were the only major problems in the three parks. Some incipient problems, such as nutrient enrichment and the presence of coliform bacteria, were indicated by the measurements. The type and degree of pollution identified by the recreationist could be important through its influence on user evaluations and space preferences. The establishment of relationships between water quality parameters and the perception of the recreationist will provide the manager with a tool to assist in evaluating participation in water-related outdoor recreation in terms of both user satisfaction and water quality.
