Effects of Climatic Change on Evapotranspiration in Zhalong Wetland, Northeast China

1 Introduction As a result of persistent increase in carbon dioxide in the atmosphere since the 1950s, global and regional climate features, such as temperature and precipitation, have ob- viously changed (Yu et al., 2002). The General Circulation Models (GCMs) provide potential climate scenarios by studying the effects of carbon dioxide on the temperature. Tickell (1993) predicted that the mean temperature will increase by 1℃ till the year 2050 and by 3℃ at the end of the 22th century. S…     

Shrinking and Drying up of Baiyangdian Lake Wetland： A Natural or Human Cause？

1 Introduction The sensitivity of ecosystems to global climate change is one of important issues for research. Many studies have indicated that wetland ecosystem is one of the most vulnerable systems (Brock and Van, 1992; Vourltis and Oechel, 1997; Burkeet, 2000; Lahmer et al., 2001; Zhang et al., 2001; Deng et al., 2003). The shrinking and drying up of wetlands in arid and semiarid areas of China have been widely observed in the recent years (Wang, 1990; Wang and Zhang, 1991; Jin, 1993; …

Effect of Nitrogen and Phosphorus on Tissue Nutrition and Biomass of Freshwater Wetland Plant in Sanjiang Plain, Northeast China

1 Introduction It has been reported that habitat nutrient availability frequently limited plant growth and determined species dominance and abundance in natural communities (Miao et al., 2000). Nutrient availability is also a main regulator of aquatic primary production. Human-induced nutrient enrichment results in die-back of native vegetation and alteration of species dominance in various aquatic eco- systems (Miao et al., 2000; Green and Galatowitsch, 2002). Particularly, nutrient enrichm…

A Method for Alpine Wetland Delineation and Features of Border: Zoigê Plateau,China

Accurate wetland delineation is the basis of wetland definition and mapping, and is of great importance for wetland management and research. The Zoigê Plateau on the Qinghai-Tibet Plateau was used as a research site for research on alpine wetland delineation. Several studies have analyzed the spatiotemporal pattern and dynamics of these alpine wetlands, but none have addressed the issues of wetland boundaries. The objective of this work was to discriminate the upper boundaries of alpine wetlands by coupling ecological methods and satellite observations. The combination of Landsat 8 images and supervised classification was an effective method for rapid identification of alpine wetlands in the Zoigê Plateau. Wet meadow was relatively stable compared with hydric soils and wetland hydrology and could be used as a primary indicator for discriminating the upper boundaries of alpine wetlands. A slope of less than 4.5° could be used as the threshold value for wetland delineation. The normalized difference vegetation index(NDVI) in 434 field sites showed that a threshold value of 0.3 could distinguish grasslands from emergent marsh and wet meadow in September. The median normalized difference water index(NDWI) of emergent marsh remained more stable than that of wet meadow and grasslands during the period from September until July of the following year. The index of mean density in wet meadow zones was higher than the emergent and upland zones. Over twice the number of species occurred in the wet meadow zone compared with the emergent zone, and close to the value of upland zone. Alpine wetlands in the three reserves in 2014 covered 1175.19 km2 with a classification accuracy of 75.6%. The combination of ecological methods and remote sensing technology will play an important role in wetland delineation at medium and small scales. The correct differentiation between wet meadow and grasslands is the key to improving the accuracy of future wetland delineation.     

Multiple Time-scale Characteristics of Runoff Variations in Middle Reaches of Huolin River and Their Effects

The Huolin River is one of the most important water sources for Xianghai wetland, Horqin wetland, and Chaganhu wetland in the western Songnen Plain of Northeast China. The annual runoff series of 46 years at Baiyun- hushuo Hydrologic Station, which is located in the middle reaches of the Huolin River, were analyzed by using wavelet analysis. Main objective was to discuss the periodic characteristics of the runoff, and examine the temporal patterns of the Huolin River recharging to the floodplain wetlands in the lower reaches of the river, and the corresponding effects of recharging variation on the environmental evolution of the wetlands. The results show that the annual runoff varied mainly at three time scales. The intensities of periodical signals at different time scales were strongly characterized by local distribution in its time frequency domain. The interdecadal variation at a scale of more than 30yr played a leading role in the temporal pattern of runoff variation, and at this scale, the runoff at Baiyunhushuo Hydrologic Station varied in turn of flood, draught and flood. Accordingly, the landscape of the floodplain wetlands presented periodic features, es- pecially prominent before the 1990s. Compared with intense human activities, the runoff periodic pattern at middle (10-20yr) and small (1-10yr) scales, which has relatively low energy, exerted unobvious effects on the environmental evolution of the floodplain wetlands, especially after the 1990s.

Monitoring System of tourist traffic(MSTT) for tourists monitoring in mid-mountain national park,SW Poland

National parks are highly valuable natural areas and have the potential to attract a large number of visitors.The number of visitors at national parks is systematically increasing,often exceeding Tourism Carrying Capacity(TCC) of trails.This situation requires adjusting the number of park visitors to adapt to sustainable management systems of visitor flow,thus preventing or counteracting overtourism.The aim of the study is to propose a comprehensive method for tourists monitoring in mid-mountain national park presented on the example of the Sto?owe Mountains National Park(SMNP) in Poland,called as Monitoring System of tourist traffic(MSTT).The study describes six stages procedure of tourists Monitoring System creation and application as an optimal measurement technique.The MSTT enabled a multidimensional analysis of tourist traffic in SMNP.With the help of 39 pyroelectric sensors and surveys data spatio-temporal characteristic of visitor flow was obtained.The data generated in MSTT included hourly,daily,weekly,monthly,and annual reports,taking into account the direction of traffic measuring both directions:entries(IN),exits(OUT) and passages(IN+OUT).The results from pyroelectric sensors were supplemented with field surveys,where visitor's motivations,preferences,and behaviours were determined.In 2017 a total of 871,344 visitors were recorded in SMNP what causes one of the most popular national parks in Poland.The SMNP is a suitable destination for short breaks leisure visits in wilderness.In order to sustain MSTT methodology in the long-run the set of guidelines together with the workload estimates were presented.In the future,the MSTT can be further developed,including monitoring of climbing,cycling,cross-country skiing,car traffic and illegal tourism assessment.The MSTT can be considered as a useful tool for tourism management in mid-mountain national parks throughout the entire calendar year.     

Recreational potential as an indicator of accessibility control in protected mountain forest areas

The article presents research findings related to recreational use of forests located in protected mountainous areas with forestage of over 80%. The study was designed to identify recreational potential of the Carpathian national parks(Bieszczady National Park, Babia Góra National Park, Gorce National Park and Magura National Park; southern Poland) and to compare these findings with the actual number of visitors. The information received on the recreational potential of parks is important from the point of view of protection of natural resources and the financial situation of the parks. The calculated ratio may be an effective tool of management for park administration, that allows to reconcile statutory social and protective functions of national parks. The study determined the recreational potential of the forests with the use of recreational valorisation method designed for areas with varied terrain, and the evaluated factors included the stands of trees with their habitat and land relief. The permissible number of national park visitors, expressed as manhour/ha/year ranges from 19.31 in Bieszczady National Park(BG: 19o 35' E, 49o 35' N) to 32.06 in in Bieszczady National Park(B: 22o 40' E, 49o 10' N). In 3 out of 4 investigated parks, Magura National Park(M: 21°25' E, 49o 30' N), Gorce National Park(G: 20o10' E, 49o 35' N), B) recreation carrying capacity was not exceeded, whether or not the strictly protected area is taken into account. Only in BG was the recreation carrying capacity exceeded by nearly 24%,or by 85% if the strictly protected area isexcluded from tourism-related exploitation. The presented procedure for monitoring access to mountain forests in national parks, from the viewpoint of natural resources conservation, can be applied in other mountainous areas covered with forests and exposed to tourist and recreational traffic,and in forests facing particular risk of recreational damage, e.g. in urban and suburban forests growing in areas with varied orography.     

Tourism versus nature conservation: reconciliation of common interests and objectives——an analysis through Picos de Europa National Park

Nature tourism and particularly tourism in national parks have acquired significant importance in contemporary societies. Post-Fordist consumers have reevaluated the meanings of ‘nature' and ‘natural spaces' and now avoid standardization to seek singularity. Tourism in national parks is a consequence of this tendency and has both positive and negative aspects. The purpose of this sociological research is to describe the most relevant conflicts in the Picos de Europa National Park(Spain) involving the park's conservation, local economic development,and tourism. Seven in-depth interviews and three focus groups were addressed to key local stakeholders.In this research were identified three chief areas of existing or potential inter-related conflicts and the main actors interacting with them. The first is on population, particularly, the negative consequences of depopulations on the local socio-economic development and the environment. A second source of conflicts identified is caused by the difficult conciliation between commercial exploitation and conservation of the protected natural area. More precisely, this specific form of tourism positively contributes to the economy of local communities whilst problems can arise for the conservation goals of National Parks. Thirdly, in this research is also analyzed the institutional governance and the inter and intra-governmental conflicts as well as with the Park's management body. These findings provide important information for the improved management of tourism and conflicting interests in natural parks.     

An analysis of first-time and repeat visitors to Korean national parks from 2007 and 2013

This paper examined visitors to Bukhansan National Park in Korea based on first-time and repeat visitation. Bukhansan National Park is Korea’s most heavily visited national park with annual visitation of six million visitors in 2015. Data used in this article were collected on-site in the park in 2007 and 2013 by the Korea National Park Service (KNPS). The study variables included socio-demographics, travel behavior, motivation, and satisfaction with park attributes, services and facilities. Data were analyzed by each study year for first-time and repeat visitors. Results showed significant differences for both first-time and repeat visitors on several socio-demographic, travel behavior, and motivation variables within each study year. For satisfaction with park attributes, facilities and services, first-time visitors were significantly different from repeat visitors on seven variables for both years. Implications are given regarding programs and services to improve visitor satisfaction and sustain the natural, cultural and historical resources at Bukhansan National Park and other national parks in Korea. Future research suggestions are provided to learn more about visitor characteristics, standards of quality and preferences in the national parks.

Community attitudes toward ecotourism development and environmental conservation in nature reserve: a case of Fujian Wuyishan National Nature Reserve,China

Using social exchange theory, this study investigated residents’ attitudes toward the preliminary stage of tourism development in nature reserves in Wuyishan National Nature Reserve of China, and the socio-economic and negative effects of residents’ attitude toward the tourist industry. Results of the questionnaire survey indicated that local people perceived they could benefit from the economic activities related to tourism, and were supportive of the conservation of natural resources and local culture, sustainable community development, and community participation in ecotourism planning and management. This study also revealed that the variables of age, gender, education level, household income, family size, non-farm work arrangements, and the distance to tourism attractions, have significant association with respondents’ attitudes toward ecotourism development, or negative impacts of the tourist industry. Respondents who are male, or have a higher household income, are more supportive of tourism development inside the reserve. Younger and more highly educated community members are more likely to support learning more about natural and cultural resources and landscapes. Respondents who have a higher household income, or live far from the village center, are more concerned about the negative environmental impacts of tourism development.     

Distance decay of place attachment and perceived authenticity of mountain tourism destinations in China

Place attachment has been a research focus in the fields of park and recreation management.Place attachment plays an important role in promoting sustainable development of parks and mountain tourism destination,however,there are limited studies that identified the spatial patterns of place attachment,especially in the context of mountain tourism destinations in China.Also,the geospatial spectrum of visitors is usually broad,examining the multivariate relationships among spatial proximity,perceived authenticity,and place attachment are essential for mountain tourism destinations to promote destination image and strengthen emotional bonding with targeted visitor groups.In this study,we selected an iconic and highly visited park,Jiuzhai Valley National Park in China,as our study site and conducted an on-site visitor survey to collect 557 samples.Study uses factor analysis and the structure equation model to analyze the relationship among spatial proximity,perceived authenticity,and place attachment.Results validate the two-dimension structure of place attachment and perceived authenticity.Study findings suggest that spatial proximity has significant impacts on existential authenticity and place identity,but has no significant impacts on place dependence.Perceived authenticity has a positive impact on place attachment.Study results advance the theories of place attachment and provide effective strategies to enhance emotional attachment between visitors and mountain tourism destinations.     

Segmentation by domestic visitor motivation: Changbai Mountain Biosphere Reserve,China

Protected areas have become important tourism products that promoted as attractions by the tourism industry. Taking the Changbai Mountain Biosphere Reserve in Northeast China as a case, this study addresses visitor needs as a basis for developing a tourism strategy aimed at enhancing tourist opportunities at this reserve. A factor-cluster approach was employed to identify visitor segment profiles based on their visit motivations. Through random sampling, a pencil-and-paper questionnaire in Chinese language was collected from 637 domestic tourists in the study area. A principal components analysis of motivations revealed eight motivational factors, and four distinct groups of tourists – Nature travelers, Cultural landscape tourists, Food shopping enthusiasts, and Eclectic adventurers – were identified. Understanding the differences in these visitor segments will help the management authority effectively analyze nature reserve attributes and provide alternative activities and services to tourists. Finally, within the dual framework of market segmentation and destination management some management recommendations and marketing implications are suggested.     

USERS′ PERCEPTION OF KOWLOON PARK, HONG KONG： VISITING PATTERNS AND SCENIC ASPECTS

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.
