Moreover, decision-makers have acknowledged and addressed social values, biodiversity, and habitat connectivity in policy documents. Canberra in the Australian Capital Territory (ACT), is a unique Australian city since it is totally designed as the National Capital of Australia and is built on a grassland plain, inspired by the Garden City concept. The green and open spaces have a symbolic value, representing Canberra as the national capital. However, Canberra is experiencing increasing urban development pressure, which threatens its green and open spaces. Thus, it is critical to explore the GI status in governance and decision-making in Canberra to guide its future planning. This research explores ten policy documents using a reflexive analysis to interpretatively critique policy documents and to diagnose the existing opportunities and constraints in Canberra’s GI planning. The documents were selected from 4 main defined scopes, Australian Government land-use responsibilities, ACT Government land-use planning and strategy, ACT Government greenspace planning, and Tree management regulations and mechanisms. This research identified dual governance (national/territory) and dual nature character (native/exotic) in the policy documents, which has intensified the complexity of GI planning. Another constraint was the lack of district level planning and a structured bottom-up approach. More flexibility in governance and collaboration between different governance levels and agencies is needed to make a more effective GI network, using the existing opportunities such as open space systems. Although GI principles have been addressed at Canberra’s strategic level, more comprehensive GI planning is needed to address all types of greenspaces."}],"$":{"view":"all","id":"abs0010"},"#name":"abstract-sec"}],"$":{"view":"all","id":"ab0010","class":"author"},"#name":"abstract"}],"$":{"xmlns:ce":true,"xmlns:dm":true,"xmlns:sb":true},"#name":"abstracts"},"pdf":{"urlType":"download","url":"/science/article/pii/S1618866722001716/pdfft?md5=585d501bacb22509f49382fe54a4422d&pid=1-s2.0-S1618866722001716-main.pdf"},"iss-first":"","vol-first":"74","isThirdParty":false,"issn-primary-unformatted":"16188667","issn-primary-formatted":"1618-8667"},{"pii":"S1618866722001753","journalTitle":"Urban Forestry & Urban Greening","publicationYear":"2022","volumeSupText":"Volume 74","articleNumber":"127632","pageRange":"127632","trace-token":"AAAAQGg-Q53MTiazxoVELOJiBAlbb7ruVCmP5E7PAGbSCdJ7ZU_WUUMiY5NNX-82OSdcgkT18emow57JGIq3D4o98aZEayNTsliDJZiwvqVcHfYwfKiG_g","authors":{"content":[{"#name":"author-group","$":{"id":"ag0005"},"$$":[{"#name":"author","$":{"id":"au0005","author-id":"S1618866722001753-ffd0727316fbb239c99756f8446978dc"},"$$":[{"#name":"given-name","_":"Jelena;Graduate Program in Sustainability Science – Global Leadership Initiative (GPSS-GLI), University of Tokyo, Kashiwa, Japan;International University of Health and Welfare, Faculty of Medicine, Narita, Japan;Institute for Future Initiatives (IFI), University of Tokyo, Tokyo, Japan;Institute for the Advanced Studies of Sustainability (UNU-IAS), United Nations University, Tokyo, Japan;Institute for Physical Activity and Nutrition (IPAN), School of Exercise and Nutrition Sciences, Deakin University, Geelong, Australia;Department of Public Health and Primary Care, Faculty of Medicine and Health Sciences, Ghent University, C.

Adolescents (n = 444, 13–18 years, 53% female) from seven schools in diverse areas of Melbourne, Australia completed an online survey at school. In response to an open-ended question, participants listed three park characteristics that would most likely discourage their park visitation. Content analysis was performed to determine categories of park characteristics from the coded responses. The six most frequently stated park characteristics that would discourage park visitation related to: play equipment (e.g., small/children’s playgrounds, no play equipment, no swings; 44% of participants mentioned the category at least once); social factors (e.g., crowded parks, presence of undesirable people; 32%); natural environment (e.g., small/no grassy space, large grassy open space; 28%); maintenance (e.g., dirty facilities, rubbish; 23%); sport/recreation features (e.g., skate park; 20%); and amenities (e.g., no shade, toilets, drink taps; 19%). To encourage more adolescents to increasingly visit parks, it is imperative for stakeholders to address the park features that they perceive as unappealing to ensure that park design caters to this important age group."}],"$":{"view":"all","id":"abs0010"},"#name":"abstract-sec"}],"$":{"view":"all","id":"ab0010","class":"author"},"#name":"abstract"}],"$":{"xmlns:ce":true,"xmlns:dm":true,"xmlns:sb":true},"#name":"abstracts"},"pdf":{"urlType":"download","url":"/science/article/pii/S1618866722002126/pdfft?md5=f884e81de81ce1765f494bbd7d55b6a2&pid=1-s2.0-S1618866722002126-main.pdf"},"iss-first":"","vol-first":"74","isThirdParty":false,"issn-primary-unformatted":"16188667","issn-primary-formatted":"1618-8667"}]},"references":{"content":[{"#name":"bibliography","$":{"xmlns:ce":true,"xmlns:aep":true,"xmlns:mml":true,"xmlns:xs":true,"xmlns:xlink":true,"xmlns:xocs":true,"xmlns:tb":true,"xmlns:xsi":true,"xmlns:cals":true,"xmlns:sb":true,"xmlns:sa":true,"xmlns:ja":true,"xmlns":true,"id":"bibliog0005","view":"all"},"$$":[{"#name":"section-title","$":{"id":"sect0115"},"_":"References

摘要

When working with any application domain, it is necessary to grasp and represent the knowledge from this application domain into a suitable form. There is naturally a significant difference between the knowledge gained from natural knowledge, estimation and experience, and the knowledge gained through exact measurement, but it is often necessary to use estimates based on experience in decision-making processes. This is especially important if this representation is to be used in decision support systems using e.g. artificial intelligence (AI) and machine learning (ML). In this paper, we therefore describe a model for valuing solitary trees that allows the use of vague evaluation of input parameters for the evaluation of trees based on fuzzy knowledge units. The creation of the model is based on the parametric method of the Nature Conservation Agency (NCA) and other methods such as CAVAT or FEM, from which the knowledge text is separated. Fuzzy knowledge units (FKU) or Knowledge units (KU) are created from this knowledge text. These FKU are trained according to data from the NCA method and optimized using the MATLAB Tune fuzzy inference system (TUNEFIS). The Adaptive neuro fuzzy inference system (ANFIS) was chosen as the best FKU model. These fuzzy knowledge units are arranged in a hierarchical model of valuing solitary trees, which is implemented in Simulink. The experimental study clearly shows that the proposed model is more detailed in some parameters than a crisp tree evaluation calculator or CAVAT calculator in excel and provides more precise results.
