Research on Campus Landscape Planning Strategy Based on the Ecological Health Effect

The water landscape in college and university is the research object in this article. Through on-site investigation, monitoring and computer simulation in campus, combined with qualitative and quantitative research methods, the advantages and disadvantages of the spatial layout of the water landscape in campus are compared. In addition, the surrounding building layout and greening layout are aslo separately studied in this article. The research results show the influence mechanism of the water landscape and its spatial layout on the ecological health effect, providing a reference experience and basis for the campus ecological landscape planning.

The Spatial Variations of Water Quality and Effects of Water Landscape in Baiyangdian Lake, North China

Baiyangdian Lake (BYD), a large shallow lake in North China, has complex water landscape patterns that are underlies spatial variations in water quality. In this study, we collected 61 water samples from three water landscapes (reed littoral zones, fish ponds and open water) and analyzed them for water quality parameters, such as dissolved organic carbon (DOC), total nitrogen (TN), and total phosphorus (TP). Water landscape distribution (determined using remote sensing imagery) was then used to assess correlations between water quality parameters and water landscape proportion in differently scaled buffer zones. There was substantial variation across all subareas, with TN and TP concentrations ranging from 0.90–4.10 mg/L and 0.06–0.18 mg/L, respectively. Spatial variations in water quality were mainly caused by water landscape distribution and external nutrient inputs. There were negative correlations between DOC, TN, and TP concentrations and the area proportion of reed littoral zones in the 300 and 500 m buffers. In contrast, DOC, TN and TP concentrations were significantly positively correlated with the area proportion of fish ponds in the 100 m buffer. Furthermore, compared with reed littoral zones, a lower nitrogen to phosphorus ratio and a higher proportion of dissolved organic nitrogen and tyrosine-like proteins were found in fish ponds. These effects were mainly attributed to development of internal sediment loadings due to nutrient exchange between sediment and overlying water. Therefore, dredging-based sediment removal from fish ponds should be considered to suppress internal phosphorus loading and accelerate recovery of the BYD ecosystem.

The distribution pattern and ecological restoration technology of aquatic plants in eutrophic water landscape belt

Taking the eutrophic Taige canal and Caoqiao River in the upper reaches of North Taihu Lake as the experimental objects, 12 monitoring points were set up and the data were recorded. The distribution pattern of aquatic plants in the water landscape belt was studied by variance/mean ratio, aggregation intensity index, negative binomial parameter, Cassie index and α – diversity index. Based on the principle of aquatic plants repairing eutrophic water, the suitable water environment was selected. The effect of ecological restoration was studied by photometry. The results showed that: the main aquatic plant communities in this area evolved from submerged type to floating leaf type and emergent type, which showed that the vertical distribution pattern of aquatic plant communities was greatly affected by hydrology; the distribution pattern of aquatic plant diversity showed a good single hump type in the vertical direction and a single hump type in the horizontal direction; the results of ecological restoration showed that: the average removal rates of TN and TP by mixing the three plants were 86.76% and 93.89%, respectively. Among them, the best combination of TN removal was water hyacinth (Eichhornia crassipes) + lytchus (Lythrum salicaria) + calamus (Acorus calamus), and the best combination of TP removal was water hyacinth + lytchus + hibiscus (Nelumbonucifera).

Island Tourism Brand Identities: A Review of Themes in Island Tourism Logos

All destinations—including islands—have an identity, shaped by the shared lived experiences and perspectives of various parties. Because sense of place is inherently reliant on human interaction (both with place and with each other), island identities are created, co-created, and communicated through various channels. One such channel is the messaging produced to market island destinations to various audiences. In marketing, a brand identity comprises the attributes or characteristics that separate one brand from another and highlight its uniqueness. Island destinations, like other tourism destinations (and brands in general), embed themes in their logos to help create a brand identity and to communicate with target audiences. The current study analyzed a sample of 84 island destination logos and identified a number of recurrent themes, with water, landscape/seascape, flora and fauna, and islandness being most prominent. Findings are discussed in the context of island identity, tourism, and marketing, highlighting opportunities for further exploration by island scholars and marketers alike. A greater understanding of island branding strategy is critical, as it offers island destinations a crucial advantage in an increasingly competitive tourism industry.

Exploring Water Landscape Adaptability of Urban Spatial Development Base on Coupling Coordination Degree Model A Case of Caidian District, Wuhan

Under the background of rapid urbanization, the study explored the adaptive relationship between urban spatial development and water landscape in different stages in Caidian District, Wuhan in order to reveal the characteristics and influencing factors of water landscape adaptability of urban spatial development and improve urban sustainability aiming at optimizing spatial development and improving water landscape function. Caidian District was seen as a complex adaptive system formed by the interaction between the base layer and the occupation layer. The assessment system of urban spatial development is constructed based on land use data and landscape pattern indices, and the coupling coordination degree model and correlation analysis were used to describe the characteristics of water landscape adaptability of urban spatial development. The results showed that: (1) the adaptation relationship between urban space and water landscape in Caidian District was becoming tense; (2) different spatial systems have unique adaptation cycles to water landscape; (3) the 1000 m buffer is the main area affected by water landscape adaptability of urban spatial development. This study provides a new perspective for the urban adaptability. Finally, improvement suggestions were put forward by three aspects of water landscape structure control, urban development control, and ecological space demarcation.

Reviving the Urban Water-Edge: History and Heritage Morphology in the Envisaging of Chittagong City

Ancient settlements were dependent on the availability of water for sustainable living, ritual values, and economic purposes. Today, many Tropical Asian cities provide examples of urban settlements within water landscapes, yet these cities struggle with water issues, and face challenges in creating a contextual morphological identity. This paper explores urban waterfront heritage through a case study of Chittagong, Bangladesh. The city is experiencing rapid unplanned urbanisation, insensitive land use and the demolition of historical buildings along waterways, which in turn has created a contextual crisis in the built environment and social living. To explore the relationship of built heritage with the water-edge, this paper examines historical architectural styles using urban morphological codes. Results show that the historical orientations, accessibility, and functions of heritage buildings are explicitly and sensitively connected with the water-edge. The paper argues that physical and spatial components of urban structure and water landscape, incorporating the lessons of urban history, could become a tool to preserve urban heritage. However, to enhance the image of the city in a sustainable manner along water-edges, it is crucial to use the potentiality of water landscape with the heritage-based morphologies in current urban design and development practices.
