Woody Species Composition, Diversity And Structure of Vegetation of Peri-Urban Park in Leo, Burkina Faso

This work aims to fill a gap in knowledge of the Burkina Faso Southern Sudanese flora and vegetation. The woody vegetation of the forest park of the Scholl Complex in Léo comprises a total of 26 families, 63 genera and 81 species including native and introduced ones. The fallow is the unit that contains all families and genera and 93% of species. The most abundant species of units of the Park are Terminalia avicennioides (Combretaceae), Piliostigma thonningii (Fabaceae-Caesalpinioideae), Daniellia oliveri (Fabaceae-Caesalpinioideae), Vitellaria paradoxa (Sapotaceae), Detarium microcarpum (Fabaceae-Caesalpinioideae), Diospyros mespiliformis (Ebenaceae), Annona senegalensis (Annonaceae) and Pteleopsis suberosa (Combretaceae).The species that regenerate the most and that will ensure the sustainability of the peri-urban forest resources are Gardenia erubescens (Rubiaceae), Piliostigma reticulatum (Fabaceae-Caesalpinioideae), Vitellaria paradoxa, Annona senegalensis, Terminalia avicennioides (Combretaceae), Diospyros mespilifomis and Azadirachta indica (Meliaceae). The most threats on vegetation and flora of the School Complex are fraudulent human exploitation, parasitic pressure and progressive intrusion of Azadirachta indica.Peri-urban park resources conservation measures concern the replanting of vegetation in degraded areas and incentives for wood production for local populations. A management program for threatened or rare species, control of invasive alien plants and domestic animals and the development and improvement of habitat to create a future urban park.

Priority modeling for public urban park development in feasible locations using GIS, Intuitionistic Fuzzy AHP, and Fuzzy TOPSIS

As feasible locations of public urban park in Bogor Municipality have been acquired in a previous study, decision makers are urgently needed to be informed on which locations should be prioritized for public urban park (PUP) development. Therefore, this study aggregates four multi-spatial criteria for PUP development priority modeling, namely distance to slum neighborhood, accessibility, slope, and land value. These four criteria in form of vector datasets were weighted using intuitionistic fuzzy analytical hierarchy process (IF-AHP) to consider the hesitancy, vagueness, and fuzziness might arise from experts’ judgement as well as from multi-spatial data processing. Resulted criteria weights from IF-AHP show that accessibility weight 0.261, land value weight 0.259, distance to slum weight 0.255, and slope weight 0.225, respectively. Criteria weights were inputted into fuzzy technique for order preference by similarity to the ideal solution (TOPSIS) and geographic information system (GIS) to rank location priority. Results from fuzzy TOPSIS show that very high priority class which has the biggest CCi values range (0.654-0.76) provides 0.14 km2 area of feasible PUP development scattered in 10 locations. The biggest area for feasible PUP development is generated by medium priority class (CCi values 0.439-0.546) in 26 locations and approximately area of 0.38 km2.

Research on Night Light Comfort of Pedestrian Space in Urban Park

The outdoor light environment significantly affects aspects of public psychological and physiological health. This study conducted experiments to quantify the effects of the light environment on visitor light comfort in urban park pedestrian space. Nine sets of lighting conditions with different average horizontal illuminance (2 lx, 6 lx, 10 lx) and colour temperatures (5600 K, 4300 K, 3000 K) were established virtual reality scenarios. Subjective light comfort was evaluated, and electroencephalogram (EEG) was measured on 18 subjects to comprehensively study the effects of different light environments on human light comfort. The results of the comprehensive evaluation showed that colour temperature had a very significant impact on subjective light comfort, with warm light being generally more favourable than cool light in enhancing human subjective light comfort. The results of the EEG analysis show that the average horizontal illuminance is an important factor in the level of physiological fatigue, and that physiological fatigue can be maintained in a superior state at an appropriate level of illuminance. Based on the results of both subjective and objective factors, a comprehensive analysis was carried out to propose a range of average horizontal illuminance (4.08 lx, 6.99 lx) and a range of colour temperature (3126 K, 4498 K) for the comprehensive light comfort zone in urban park pedestrian space.

Functional Classification of Urban Parks Based on Urban Functional Zone and Crowd-Sourced Geographical Data

Urban parks have important impacts on urban ecosystems and in disaster prevention. They also have diverse social functions that are important to the living conditions and spatial structures of cities. Identifying and classifying the different types of urban parks are important for analyzing the sustainable development and the greening progress in cities. Existing studies have predominantly focused on the data extraction of urban green spaces as a whole, while there have been relatively few studies that have considered different categories of urban parks and their impact, which makes it difficult to characterize or predict the spatial distribution and structures of urban parks and limits further refinement of urban research. At present, the classification of urban parks relies on the physical features observed in remote sensing images, but these methods are limited when mapping the diverse functions and attributes of urban parks. Crowd-sourced geographic data may more accurately express the social functions of points of interest (POIs) in cities, and, therefore, employing open data sources may assist in data extraction and the classification of different types of urban parks. This paper proposed a multi-source data fusion approach for urban park classification including POI and urban functional zone (UFZ) data. First, the POI data were automatically reclassified using improved natural language processing (NLP) (i.e., text similarity measurements and topic modeling) to establish the links between urban park green-space types and POIs. The reclassified POI data as well as the UFZ data were then subjected to scene-based data fusion, and various types of urban parks were extracted using data attribute analysis and social attribute recognition for urban park mapping. Experimental analysis was conducted across Beijing and Hangzhou to verify the effectiveness of the proposed method, which had an overall classification accuracy of 82.8%. Finally, the urban park types of the two cities were compared and analyzed to obtain the characteristics of urban park types and structures in the two cities, which have different climates and urban structures.

An Assessment of Recreational Functions of Botanical Parks in Urban Ecosystems

In the changing world, pandemics have entered human life and people want to relieve the stress and relax that these new living conditions they meet. Parks in the urban ecosystem are one of the indispensable elements in this sense. In this context, while botanical parks contribute to the urban ecosystem, they also meet the recreational needs of people.In this study, a survey was carried out for assessing the recreational quality of Bakırköy Botanical Park in Bakırköy, Istanbul, which is Turkey’s most important metropolitan city. The results of the survey reveal that the users perceived Bakırköy Botanical Park as an urban park, and the findings reveal that young users (26-35 years old) visited the park mostly within 1-3 hours. In addition to being a park to get away from the crowd (78.00%) in terms of comfort and image, the presence of children’s playgrounds is also considered an important recreational function for users (66.80%). Although the park has some deficiencies in terms of reinforcement elements and negligence, observations exhibited that it cannot fulfill its education and research functions adequately as a botanical park. Hence, the plants in the park must have labels. It would be an appropriate approach to make the necessary arrangements for Bakırköy Botanical Park to maintain both its recreational and educational functions, and to consider the protection-use balance in the arrangements.

Research on the Mechanism of Public Participation in the Planning and Design of Urban Park Playground

Over the recent years, citizens in Taiwan have proposed increasingly stringent demands and standards for urban park playgrounds. Thus, this study aimed to explore and discuss mechanisms for public participation in its planning and design procedures. Furthermore, this study proposed suggestions on mechanisms for public participation in the planning and design process by analyzing public recognition in each of the four phases of public participation. Moreover, questionnaires were distributed to experts and interviews were conducted among park users to gather the appropriate data. The research result showed that participatory design could effectively improve public recognition toward urban park playgrounds and earn confidence among citizens. However, it is noteworthy that the public favors social media communications over traditional forms. On the other hand, the public shows disapproval of a ribbon-cutting ceremony. Finally, the proposed suggestions and recommendations of this study are formulated based on the research findings
