Landscape Image Layout Optimization Extraction Simulation of 3D Pastoral Complex under Big Data Analysis

Abstract

Big data has brought about opportunities for landscape architecture, changing the design thinking of layout optimization simulation, expanding the platform for public participation in layout optimization simulation design, reflecting social and humanistic care, and promoting the integration of discipline cooperation and data. At the same time, it also brings about challenges. The proposal of data theory, the acquisition and analysis of data, and the protection of privacy are all issues that we need to face and solve. First, build a layout optimization simulation program under the background of big data. Follow the procedures of conventional layout optimization simulation, add big data analysis technology to the preliminary analysis, layout optimization simulation design, and later evaluation management, introduce new data processing methods, and build a theoretical framework of landscape optimization simulation methods that integrate new and traditional data. Second, studying the evolution of the landscape image layout of the three-dimensional pastoral complex is different: the overall landscape image layout of the three-dimensional pastoral complex shows a trend of fragmentation and heterogeneity. Among them, the arable land is gradually fragmented, the wetland and water area are simplified in form, the woodland and grassland patches are gradually distributed, the fragmentation is reduced by 76.19%, and the connectivity index is gradually increased. From a spatial perspective, the edge area outside the Fourth Ring Road becomes the most obvious area of fragmentation tendency. Finally, by introducing big data into the landscape layout optimization simulation, a layout optimization simulation method based on big data is constructed and used in the layout optimization simulation of the landscape image layout of the three-dimensional pastoral complex to guide the participatory layout optimization simulation.

Simulation of Automatic Color Adjustment of Landscape Image Based on Color Mapping Algorithm

“…However, under gradually increasing light conditions, the position of the response curve will move parallel to the right along the X -axis. This movement shows that if there is sufficient time to adapt to the lighting conditions, the visual system always maintains the lighting response of three to four logarithmic units on the logarithmic brightness coordinate axis [ 15 ]. This movement can also be achieved by setting different σ value to complete the simulation, so rewrite formula ( 13 ) as the following formula: …”

Landscape Planning and Management Methods of Beautiful Rural Pastoral Complexes under the Background of Big Data

“…Researchers have done a lot of research on the design and management of pastoral complexes and landscapes using different methods, and these research studies have achieved good results and utilization values. Du and Long [19] believed that big data technology brings new opportunities for the layout optimization of landscape architecture, which also promotes the mutual development of discipline integration and big data technology. He built a simulation program for landscape architecture layout optimization, which was also used in the trend prediction of three-dimensional pastoral complexes, and it predicted the fragmentation and heterogeneity of pastoral complexes.…”
