Ecological Remediation Measures for Non-point Source Pollution Based on Source-Sink Landscape Theory: A Case Study of Huanghou Basin

The growth of society and population has led to a range of water pollution issues.Among these,non-point source pollution assessment and treatment pose a particular challenge due to its formation mechanism.This has become a focal point and challenge in water pollution treatment research.The study area for this research was the Huanghou basin in Guizhou Province,southwest China.The land use type of the basin was analyzed using remote sensing technology,and water quality data was collected by distributing points throughout the basin,based on source-sink landscape theory.The distribution map of the basin’s source-sink landscape and the results of water quality data accurately and efficiently identified the areas with high risk of non-point source pollution in the western and southwestern residential and agricultural areas of the upper basin.Hence,a strategy of“increasing sinks and decreasing sources”was proposed.The strategy was implemented at both macro and micro levels to address non-point source pollution in the basin using ecological remediation techniques.The work to control karst rocky desertification should continue at a macro level.The rocky desertification area in the basin should gradually transform into grassland and forested land,while increasing the overall area of the sink landscape.Ecological restoration techniques,such as slope planting,riparian zone vegetation restoration,increasing plant abundance,and restoring aquatic plants,can effectively control non-point source pollution at the micro level.Compared to traditional control methods,this remediation strategy focuses on source and process control.It is more effective and does not require large-scale water pollution control projects,which can save a lot of environmental control funds and management costs.Therefore,it has greater research significance and application value.

Landscape Planning Principles and Techniques for Residential Districts

Landscape design principles for residential districts were analyzed in this study,it was stressed that local features should be demonstrated,actual conditions of the site respected;functional demands of residential districts should be clarified;landscape designs and architectural designs should be organically combined;central landscapes should be highlighted,sense of hierarchy and enclosure created;human-concerned and ecological principles should be followed.On this basis,landscape design techniques for residential districts were discussed from the perspectives of artistic conception and plant furnishing.In terms of plant furnishing,spatial processing,linear changes and changes of seasonal aspects were emphasized,and plants with environmental and economic benefits were suggested.By doing this,this study aimed at contributing to the future planning and construction of residential districts.

Source-sink landscape spatial characteristics and effect on non-point source pollution in a small catchment of the Three Gorge Reservoir Region

The source and sink landscape patterns refer to landscape types or units that can either promote positive evolvement of non-point source(NPS) pollution process, or can prevent/defer the ecological process, respectively. Therefore, the role of a catchment landscape pattern in nutrient losses can be identified based on the spatial arrangement of source and sink landscapes. To reveal the relations between landscape spatial characteristics and NPS pollution in small catchment, a case study was carried out in a Wangjiagou small catchment of the Three Gorges Reservoir Region(TGRR), China. Google earth imagery for 2015 were processed and used to differentiate source and sink landscape types, and six subcatchments were selected as sample regions for monitoring nitrogen and phosphorus nutrients.Relative elevation, slope gradient and relative flow length was used to construct the Lorenz curves of different source and sink landscape types in the catchment, in order to assess the source and sink landscape spatial characteristics. By calculating the location-weighted landscape indices of each subcatchment and total catchment, the landscape spatial load characteristics affecting the NPS pollution was identified, with a further Pearson correlation analysis for location-weighted landscape indices and nitrogen-phosphorus monitoring indicators. The analysis of Lorenz curve has revealed that the obtained distribution trend of Lorenz curve and curve area quantified well the spatial characteristics of source and sink landscape pattern related to the relative elevation, slope gradient and relative flow length in small catchment. Results of Pearson correction analysis indicated that location-weighted landscape index(LWLI) combining of terrain and landscape type factor did better in reflecting the status of nitrogen and phosphorus loss than the indices related to relative elevation, slope gradient and relative flow length.

Adopting an ecological view of metropolitan landscape: the case of “three circles" system for ecological construction and restoration in Beijing area

Ecological construction and restoration for sustainable development are now a driving paradigm. It is increasingly recognized that ecological principles, especially landscape ecology theory, are not only necessary but also essential to maintain the long-term sustainability worldwide. Key landscape ecology principles—element, structure and process, dynamics, heterogeneity, hierarchies, connectivity, place and time were reviewed, and use Beijing area as a case study to illustrate how these principles might be applied to ecological construction and restoration, to eventually achieve sustainability. An example to more effectively incorporate the ecological principles in sustainable planning in China was presented.

An approach to the design principles for indicator system of desertification degree

From the analysis on the problem of selection, data acquisition, quantification and accuracy check in the indicators to desertification degree both at home and abroad, one might conclude that in the existing assessment of desertification degree there is a prevailing tendency which is the substitution of absolute landscape for relative land degradation, namely, assessment of desertification degree is that of absolute landscape state to some extent. As a result the reassessment accuracy of desertification scope, damaging degree and control effect are affected. The regaining and establishment of the initial and final ecological datum level of land degradation are the prerequisite to the establishment of normal scientific indicator system. From the viewpoint of this three design principles of indicators to the desertification degree are put forward: the zonal principle of indicator systems decided by the ecological datum level corresponding to their bioclimatic zones, the hierarchical principle of indicator systems decided by different spatial scales and the resolutions of different sensors and principle of landscape types based on the 3S as core-indicator.

Bringing Systematic Thinking of Landscape Justice Into Global Design Practice

Design increasingly plays a pivotal role in achieving justice for all.However,there are often gaps between visions and implementation due to the variety of factors and stakeholders involved in design practice.Through literature review and a keyword co-occurrence analysis,this paper investigates current landscape justice research and identifies the distinguishing concerns in design,and highlights the importance of systematic thinking in achieving landscape justice.By examining the practices of the British company Building Design Partnership(BDP),a multinational design company,this paper identifies BDP’s three key design principles as experiences can be followed for landscape justice:design for inclusion,design for resilience,and design for future ecosystems.The paper also addresses potential challenges and conflicts in implementing landscape justice across different contexts and highlights multinational design companies’efforts to mediate between various stakeholders.Finally,this paper demonstrates that design companies can contribute to 1)bridging social and environmental justice through landscape design,2)achieving the visions promoted by scholars,3)identifying and deploying diverse approaches to achieving landscape justice with their sensitivity to practical problems,and 4)fostering integrated feedback loops via both top-down and bottom-up approaches to ensure effective implementation of landscape justice.
