Recreational Behavior and Spatial Characteristics of Urban Parks Based on Multi-Source Information: A Case Study of Xiaohong Stone Carving Park in Nanjing

Urban parks are an important part of urban recreational spaces,and the development of analysis framework of recreational behavior and space is helpful for the design of urban parks to better meet the activity and usage requirements of visitors.In this paper,Xiaohong Stone Carving Park in Nanjing was taken as the research object to explore the relationship between landscape space and user behavior for design feedback.The orthographic image technology of unmanned aerial vehicle(UAV)and machine deep learning were used to analyze users behavior activities in the park,and the spatial characteristics of each node in the park were evaluated by semantic differential scale to explore the potential causes of behavior activities.The results showed that①there were significant differences in the number of visitors on holidays and working days,and young people and children were the main users.②The users activity of the park differed greatly on the inner and outer tour roads,and the users showed stronger willingness to stay on the inner tour roads.Recreational activities received more attention than cultural ones.③The overall distribution of users was significantly affected by hydrophilicity,and the recreational behavior and activity type were affected by multiple factors which include the hydrophilicity,safety,accessibility of cultural relics and the amount of recreational facilities.Finally,the enhanced strategies such as improving the cultural tour system,establishing hydrophilic safety belts and optimizing recreational facilities were put forward.

Studies on Classification of Recreational Fishery Resources and Evaluation on its Development

Recreational fishery is the combination of traditional fishery and modern leisure activities.Development of recreational fishery resources must be based on related resources,but the present research on recreational fishery is mainly confined to the development of leisure projects,the definition of connotation and scope of recreational fishery resources is rather vague,and there is no precise classification and evaluation system.According to the resources attributes,resources functions,and tourism resources classification,investigation and evaluation standard,recreational fishery resources include a number of different types.Expert Scoring Method and Analytic Hierarchy Process can be used to determine the evaluation factors of recreational fishery resources and their weights,and then make comprehensive evaluation on recreational fishery resources of different regions and types,so as to improve the scientific nature of recreational fishery development.

A regionalized IO-model to value seasonal recreational ecosystem services in a mountain National Park in Spain

Recreational Ecosystem Services(RES)are among the most frequently evaluated ecosystem services.RES are seen as a major opportunity for sustainable development in areas of high ecological value resulting from the presence of emblematic species,habitats or scenery,often integrated in conservation areas,in particular in mountain areas affected by depopulation,rising environmental risks and poverty.Economically,the assessment of RES has been based on Contingent Valuation and Choice Experiments,methods with limitations related to their subjectivity.Alternatively,Input-Output(IO)models provide a very accurate and effective way of valuation of RES with regional information regarding interindustry transactions.Whilst data on nature tourist expenditure may be only available annually,tourism inflows have a strong seasonal behavior,which impacts the profitability of several local economic activities.In this paper,we firstly constructed a novel regionalized IO-model based on Cross-Industry Location Quotients using employment data and,secondly,based on Monte Carlo simulation,we estimated nature tourist expenditure monthly using data on nature tourism inflows.This method allowed for a more precise RES evaluation,estimating direct,indirect and induced monthly economic impacts of nature-based tourism.The method was applied to the Ordesa and Monte Perdido(OMP)National Park in the Spanish Pyrenees.To estimate the average tourist expenditure,we collected and analyzed spending on commerce,hospitality and restaurants,leisure,and transport of 385 visitors.Results suggest that using a regionalized IO model leads to a considerable reduction of over-estimation of the economic impact of tourist expenditure estimated by conventional methods.Taking into consideration the direct,indirect and induced effects of tourist expenditure in 2016-2018,the total annual output effect in the OMP National Park amounted to€208.8 million,while the total income effect amounted to€86.29 million.Also,a total of 2,429 jobs were created which indicates that for each thousand annual visitors to the National Park,3.8 jobs are created in the surrounding area.Overall,the proposed methodology can be easily applied to the remaining National Parks in Spain or other regions in the world,making it a valuable tool to estimate the value of RES in areas affects by strong seasonality,to set priorities and support regional policies for mountain sustainable development.

Recreational Use of Acidic Pit Lakes—Human Health Considerations for Post Closure Planning

Pit lakes may form in mining voids that extend below groundwater level after mining ceases and many have been found to have elevated metals concentrations and low pH through acidic and metalliferous drainage (AMD). Pit lakes are often used for recreational activities including swimming, fishing and boating and poor water quality may present health risks to recreational users. Pit lakes also provide the opportunity for additional water resource uses. The Collie Coal Basin in south-western Australia currently has a number of pit lakes with moderate AMD effects which are also used for recreational pursuits. Twelve hundred questionnaires were mailed to selected addresses in the Collie shire with an additional 170 questionnaires to specific interest groups. Participants were asked about the type of activity, frequency and duration and any health symptoms experienced after use of the lakes. Two hundred and fifty questionnaires were returned, which comprised 176 returns from the random sample and 74 from the targeted sample. Three pit lakes with elevated metals concentrations and low pH were used for recreational purposes by 62% of respondents. This was mostly in summer with swimming the most common activity. Of all respondents 52% were concerned about lake water quality and 38% using the lakes reported a variety of symptoms. Recreational use of Collie pit lakes did not represent a health risk for most of the surveyed population due to the low frequency and duration of use, however health risks may be elevated in sensitive users such as children and those consuming seafood from the lakes. Comprehensive water quality monitoring for chemicals and further characterisation of recreational use of pit lakes is warranted to more comprehensively assess the potential health risks to recreational users. Post closure mine plans need to consider potential future community uses combined with assessments of water quality and physical characteristics to reduce the potential for adverse health and safety impacts.

Diurnal Variation of Volatile Organic Compounds in Recreational Forests and Its Relationship with Microclimate Factors

This study used the dynamic headspace adsorption(DHS) to collect volatile organic compounds(VOCs) released from the Fokienia hodginsii forest in summer, and analyzed the the composition and concentration of VOCs and their correlation with environmental factors. The results showed that: there were 165 types of VOCs in the Fokienia hodginsii forest;the diurnal variation of the concentration of total volatile organic compounds(TVOCs) was "W"-shaped, the concentration reached its peak at 13:00–15:00 and its trough at 1:00–3:00;VOCs beneficial to human health mainly appeared at 13:00, while VOCs harmful to human health chiefly occurred at 11:00–19:00. The correlation analysis between the concentration of VOCs and climatic factors indicated that the concentration of VOCs was basically proportional to the temperature and illumination intensity and inversely proportional to the humidity and wind speed. In other words, the diurnal variation of the concentration was consistent with the diurnal variation of temperature and illumination intensity.

Design of Natural Children’s Recreational Spaces and Facilities in Urban Neighborhood Parks

Taking into account problems existing in urban children’s recreational spaces, this paper mainly discussed the method to design natural children’s recreational spaces and facilities, analyzed the characteristics and influencing factors of natural children’s recreational spaces and facilities based on the characteristics of behavioral and psychological cognition of preschool children, and concluded that children’s recreational spaces consist of five parts, namely, the border, entrance, internal activity space, viewing space and supporting space and that the design of recreational facilities should meet the four points of naturalness, appropriate fuzziness, appropriate scale and size, and diversities and opportunities, with a view to providing a reference for the design of children’s recreational spaces and facilities.

Recreational Attractiveness of Urban Parks and Implications for Their Management:A Case Study in Changchun,China

Urban parks are an important part of urban ecosystems and also provide recreational services for urban residents.However,it is still unclear how the recreational attractiveness of urban parks can be evaluated.In this study,12 typical parks in Changchun,China were selected for evaluation of their recreational attractiveness.We built a recreational attractiveness evaluation system based on the analytical hierarchy process(AHP)to produce a composite evaluation index.This method included:1)the landscape quality of the parks;2)the recreational facilities;3)the conditions of the area;and 4)the accessibility of the parks.Our results showed that Nanhu Park,Children’s Park,Shengli Park,and Jingyuetan Forest Park had high recreational attractiveness,whereas Linyuan Park had the lowest attractiveness among the 12 parks.These results agreed with the information obtained from a field survey of the actual recreational and revisit rates,which showed that the evaluation index is reliable.Correlation analysis showed that the landscape quality and recreational facilities of parks had a direct effect on their recreational attractiveness.A negative correlation was found between the accessibility of a park and its recreational attractiveness.We conclude that if the scenery and facilities are not as good as a visitor expects,then they may choose to visit a different park,even if it takes a longer time to reach.

Application of Matrix Approach for Evaluation and Assessment the Potential of Recreational Ecosystem Service in Model Regions in Slovakia

Recreation and tourism are important for economic growth and human wellbeing. They are directly related to the cultural services provided by ecosystems. Recreational services, as part of tourism, have the greatest potential for development within the sector of services in the Slovak economy, and they are able to generate a significant number of new jobs especially in small rural regions. There is a gap in the literature providing assessments of geographically small regions in relation to their potential to provide different types of ecosystem services. The aim of the article was to evaluate and assess the recreational potential of ecosystem services in two small pilot regions of the Slovak Republic, Brezno district and Krupina district. Modified matrix of indices was used. Results showed that Brezno district has a higher area of ecosystems with a higher potential for recreation, therefore the conditions for recreation and tourism are much better in comparison to Krupina district. However, the use of recreation potential in Brezno district is negatively affected by the availability of sites and transport options, which is reflected in a lower ratio of visitors to the capacity of recreation potential. This finding opens up discussion about opportunities to create new jobs within sustainable tourism in Brezno district. This study provides an alternative view to the assessment and evaluation of the recreational potential of ecosystem services in small regions. Moreover, the methodology developed in this paper is replicable and could be applied by planners using geographical information systems.

Response of tropical avifauna to visitor recreational disturbances: a case study from the Sinharaja World Heritage Forest, Sri Lanka

Background: We investigated the impact of human recreational disturbances on the distribution of birds along a popular nature trail in Sinhararja World Heritage Forest, Sri Lanka. It was hypothesized that visual and noise stimuli caused by the presence of humans affect the distribution of avifauna associated with this nature trail.Methods: Nine circular plots of 25 m fixed-radius laid along the trail(0 m), and 18 plots laid perpendicular to the trail at 75 and 150 m intervals, were studied from March 2013 to January 2014. The degree of human recreational disturbances was assessed in terms of visitor group size(visual disturbance) and their noise level(sound disturbance). These disturbances were categorized along a four-point scale(no human disturbance, low, medium and high disturbance). The relationship between disturbance levels and the abundance of birds was statistically tested.Results: ANOVA results revealed that the abundance of birds differed significantly under various intensities of recreational disturbances at each distance level. A significant negative correlation between abundance of birds and intensity of disturbance at 0 m distance suggests an avoidance of edge habitats by birds in the presence of humans. Abundance of birds increased at the 75 and 150 m distance levels with increasing disturbances occurring at the trail. Significant negative correlations were further observed between disturbance level and the abundance of birds in ground/understory and sub-canopy vertical strata of the forest at 0 m distance.Conclusions: Under high levels of recreational disturbance occurring at this trail, the abundance of birds near the trail declined significantly, while bird abundance in the interior of the forest increased. The sensitivity of individual bird species to visitor disturbances varied with the vertical stratum of the forest they usually occupy. Birds occupying the ground, understory and sub-canopy are particularly sensitive to recreational disturbances while bird species occupying the canopy and above are less vulnerable to recreational disturbances.

Prevalence of Cryptosporidial Oocysts in Soil of Recreational Parks in Abuja, Nigeria

Contamination of soil with cryptosporidial oocysts poses a great health risk to people especially in individuals who are immune-compromised. Exposure to contaminated soil can cause diarrhoea in humans especially in children who play around the parks and may not wash their hands before handling food. The prevalence of cryptosporidial oocyst in soils of 4 recreational parks in Abuja, Nigeria was investigated. Four hundred soil samples were collected from various locations within the recreational parks and examined for the presence of cryptosporidial oocyst using modified acid fast staining technique. In nine (2.3%) of the samples, 8 were from park A and 1 was from park B contained cryptosporidial oocyst. There was significant association (χ2 = 20.1;df = 2;p = 0.00004) between prevalence of Cryptosporidium oocysts and level of hygiene of the parks. It was concluded that soil in recreational parks may be a source of infection with Cryptosporidium oocysts.

Monitoring Recreational Waters: How to Integrate Environmental Determinants

Recreational waters are associated with a higher risk of disease for people engaged in activities that bring them into contact with these waters. The primary cause of contamination of recreational waters is fecal microorganisms, which may originate from various sources and involve several modulating factors, making it a complex public health and en- vironmental issue. Monitoring recreational water quality should include two key components: Microbial water testing and monitoring environmental determinants associated with higher risks of contamination. Conducting both activities provides the foundation for a comprehensive assessment according to risk and the actual level of fecal pollution and thus could promote good management actions to ensure safe water quality. Nevertheless, monitoring of environmental determinants is rarely fully integrated in monitoring programs and is also harder to achieve, especially when water pol- lution is mainly associated with nonpoint sources. In order to achieve identification and monitoring of environmental determinants associated with fecal contamination of recreational waters, some specific steps should be followed and some questions must be answered. The objective of this review article is to present current knowledge on this topic and to suggest and discuss recommendations. Potential sources of contamination and factors able to modulate them should be identified and measured after the geographical area influencing fecal contamination of recreational water has been delineated. Statistical models have been developed to identify the relative importance of these environmental characteristics on fecal pollution of recreational waters but they do not allow for a full comprehension of the exact processes leading to this pollution, thus other methods should also be used to better understand these processes.

Examining the Level of Service in the Context of Recreational Carrying Capacity in the Erzurum Urban Forest,Turkey

Urban forests are confronted with high using pressure because of the increasing demand for recreation and accessibility of these settings. For that purpose, defining and managing recreational carrying capacity is considered as significant in ensuring ecological value’s and recreational satisfaction’s continuity. The purpose of this paper is to investigate the carrying capacity of Erzurum Urban Forest with respect to Level of Service (LOS) as a new management technique that focuses on service quality and visitor satisfaction. The data were obtained by self-administered questionnaire conducted with 166 visitors on weekends and holidays during summer season of the year 2014. Data were analyzed by dimensions/indicators of recreational satisfaction and socio-demographic characteristics with intent to identify tolerance range of visitors. The contribution and relative importance of each of the indicators to the overall satisfaction were analyzed by using Ordinal Logistic Model (OLM). The results indicated that the four indicators were at the greatest degree;“distance from picnic spot to toilets” and “quantity of children’s playground facilities” were decease of overall satisfaction while “distance from picnic spot to parking” and “level of shade at picnic spot” had a positive contribution to the overall satisfaction. The outputs from these analyses were used to calculate LOS. It was revealed that the level of service (0.40) in Erzurum Urban Forest was below the moderate level. Planning and managing strategies for optimizing the LOS were developed and discussed by considering these results.
