Most studies on the effects of tillage operations documented the effects of tillage on losses through surface runoff. On flat areas, the subsurface runoff is the dominating pathway for water, soil and nutrients. This study presents results from a five-year plot study on a flat area measuring surface and subsurface runoff losses. The treatments compared were (A) autumn ploughing with oats, (B) autumn ploughing with winter wheat and (C) spring ploughing with spring barley (n = 3).
Public Perceptions on City Landscaping during the Outbreak of Coronavirus Disease: The Case of Vilnius Pop-Up Beach, Lithuania
The article sought to understand public perceptions on city landscaping during the outbreak of COVID-19. The research aimed to discuss the theoretical aspects related to restrictions on travel during the pandemic and city landscaping and to conduct an empirical study of experiences of the Vilnius Pop-up Beach, Lithuania. The thematic analysis selected for the empirical study is not limited and flexible, allowing for revealing the experiences and public opinion, including that expressed in the media, relating to the Vilnius Pop-up Beach.
How to Perceive the Trade-Off of Economic and Ecological Intensity of Land Use in a City? A Functional Zones-Based Case Study of Tangshan, China
China, in a rapid urbanization process, is accompanied by the expansion of built-up land, population accumulation, and intensive land investment, while the improvement of the urban environment cannot keep up with the population and economic density growth. Therefore, the purpose of this paper is to discuss the balance between urban land use economic intensity (built-up area density, population density, land price) and ecological intensity (the depth, breadth, and integration of ecological spaces) in Tangshan.
Study on the Spatial Classification of Construction Land Types in Chinese Cities: A Case Study in Zhejiang Province
Identifying the land-use type and spatial distribution of urban construction land is the basis of studying the degree of exposure and the economic value of disaster-affected bodies, which are of great significance for disaster risk predictions, emergency disaster reductions, and asset allocations. Based on point of interest (POI) data, this study adopts POI spatialization and the density-based spatial clustering of applications with noise (DBSCAN) algorithm to accomplish the spatial classification of construction land.
Examining the Coupling Coordinated Relationship between Urban Industrial Co-Agglomeration and Intensive Land Use
Exploring the dynamic relationship and coupling coordination between urban industrial co-agglomeration and intensive land use is vital to ensure high-quality urban development. Based on an industrial co-agglomeration model, a revised intensive land use model, and a coupling coordination model, this paper comprehensively measured the urban industrial co-agglomeration and intensive land use coupling coordination in eight cities in the Chengdu metropolitan area from 2004 to 2018.
