However, asymmetric movement caused by the subjectivity of animals and environment heterogeneity is seldom considered in EN design. To design EN based on asymmetric movement, an individual-based model, PDArunner, is developed, which can identify corridors based on explicit movement paths. Since the urban–rural fringe is susceptible to landscape change, a multi-species EN based on asymmetric movement is designed for Jinnan district, Tianjin, China by simulating movement of <em>Mustela sibirica</em>, <em>Spilopelia chinensis</em> and <em>Gallinula chloropus</em> using PDArunner. Asymmetric movement is partitioned based on the size of departure and arrival habitats. Asymmetric corridors are thus identified based on movement in particular direction. In Jinnan, successful transfer rate of focal species from small to large habitat increases with difference in habitat size. The spatial extent of asymmetric corridors is more concentrated for <em>G. chloropus</em>. There are more corridors from large to small habitats than in the opposite direction, especially for <em>S. chinensis</em> and <em>G. chloropus</em>. There are more one-way corridors for <em>S. chinensis</em> and <em>G. chloropus</em> than <em>M. sibirica</em>. Perceptible high vegetation coverage places with large enough contrast to environment are suggested to be consecutive within 50 m for <em>M. sibirica</em> in Jinnan, which also benefits <em>S. chinensi</em>. <em>G. chloropus</em> can benefit from well-conserved water quality and quantity. A cross-administration collaboration is also highlighted for large scale conservation.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"254 ","pages":"Article 105253"},"PeriodicalIF":7.9,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dependencies between socioeconomic profile, residential location, preferences and behavior make this kind of analysis difficult. Further, beyond understanding where diverse social interactions take place, it is important to know whether increasing access to those types of spaces via changes to the transportation network can actually increase the level of diversity in social interactions—a more causal question that remains relatively unexplored in the literature. This study presents new perspectives on analyzing social mixing and socioeconomic integration in cities using geolocated cellphone data. Using a call detail record dataset which describes the movements of over one million cell phone users in Stockholm, Sweden, this study quantifies the contribution of access to various types of urban amenities to one’s exposure to people with diverse income levels. Our results provide evidence that areas of the city with more libraries, educational institutions, healthcare establishments, parks and restaurants host more exposures between people who are different from one another in terms of income. Further, we leverage random shocks to the transportation network that come from maintenance-based road closures to identify a causal relationship between access to parks, services and healthcare establishments and experienced income diversity. Temporary, random increases in travel times to these spaces due to road closures result in less diverse day-to-day encounters for urban residents.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"254 ","pages":"Article 105250"},"PeriodicalIF":7.9,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this salient gap, the present study examines the overall urban green space accessibility, the moderating effects of PUPs, and the heterogeneous and dynamic perception of these effects across diverse social groups in Hong Kong between 2000 and 2020. The results demonstrate that PUPs significantly reshape the UGS accessibility pattern across different time catchments, manifested by mitigating or even reversing the disparity between urban core and peripheral areas. For the moderating effect of PUPs, despite the general trend of reduced inequalities, recent years have witnessed an increase in the inequalities between urban districts. The findings further reveal the diverse benefits derived from PUPs for different population groups and neighborhoods. Women, the elderly, low-income groups, highly educated groups, and ethnic minorities tend to benefit less from PUPs, while children and local residents experience greater advantages. Larger households and nuclear family households have increasingly relied on PUPs, while households with housing advantages (larger size and homeownership) also enjoy more significant benefits. Notably, socio-economically disadvantaged and aging neighborhoods have experienced less and diminishing benefits from PUPs. This research offers comprehensive evidence to enhance the understanding of the relationship between peri-urban and urban parks and their impact on environmental justice, thus better informing equity-orientated UGS planning and policy-making.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"254 ","pages":"Article 105244"},"PeriodicalIF":7.9,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pollutant mixtures and habitat degradation can combine to apply stress on community diversity. Water quality is influenced by the assemblage and mosaic of catchment land cover. Amongst a wider suite of Nature-Based Solutions, the value of urban woodland is increasingly recognized as having potential to support a range of ecosystem services. Despite an increasing focus on establishing urban woodland for aquatic conservation, its actual influence is yet to be manifested. Therefore, we explored trees’ location in riparian and upstream catchment, within and outside of the urban area. We conducted a combination of systematic literature review and statistical analysis to better understand the woodland influence. Despite the wide range of bioindicators studied and broad worldwide spectrum of geo-climatic regimes covered, literature evidence for benefits were found in at least half the cases. With a focus on the overall family richness and the sensitive orders Ephemeroptera, Plecoptera and Trichoptera family richness as bioindicators, the statistical analysis comprised a national study in England covering 143 sites with substantial urban cover, totaling 4226 invertebrate community observations over 30 years. Two satellite-derived land cover maps were used to enable discrimination between urban and extra-urban woodland. The analysis supported the literature evidence that impervious land had negative effects and woodland positive effects. In the urban and upstream catchment, woodland was more important than pasture or cropland. There was some evidence of those woodland effects being more advantageous when trees are located within the urban area itself. Benefits attributable to woodland were distinctly apparent against a backdrop of improving macroinvertebrate diversity found to be synchronous with long-term reductions in urban pollution signatures. The presence of sparse land, even in small amounts, was detrimental to macroinvertebrate diversity. These areas of low vegetative cover might be detrimental due to high sediment input and legacy industrial contamination. Given the increasing accessibility of land cover data, the approach adopted in this case study is applicable elsewhere wherever macroinvertebrate community data are also available.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"254 ","pages":"Article 105251"},"PeriodicalIF":7.9,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We focus on the role of both formal institutions and the perceptions that people form of spatial features and their meanings and functions, and the manner in which these intermediaries shape human-nature interactions and the co-production of nature’s wellbeing impact. Our findings from quantitative and qualitative data demonstrate that urban nature contributes to all aspects of a five-dimensional notion of wellbeing. But social housing residents’ and young peoples’ ability to experience these benefits is limited. Informal mechanisms of social control such as perceptions of ownership of space and its appropriate uses, and fear of conflict and crime limit the extent to which residents access greenspaces and the activities within them. Together with formal institutions such as tenancy types, housing targets and criteria for optimisation of site allocation, they produce hierarchies of use of public greenspaces and reinforce existing divisions between people of different demographic and socio-economic status. The findings underline the need to facilitate the establishment of shared and inclusive norms concerning access and appropriate uses of natural spaces in housing and greenspace delivery.</div></div>","PeriodicalId":54744,"journal":{"name":"Landscape and Urban Planning","volume":"254 ","pages":"Article 105241"},"PeriodicalIF":7.9,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142555534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
