Abstract
Aiming at the problem of slow convergence in the parallel calculation of patch area landscape art index, a parallel calculation method of patch area landscape art index based on land cover data was proposed. Firstly, patch type area index, patch connectivity index, patch number index, and fragmentation index were selected as patch area landscape art spatial staggered pattern indexes to conduct characteristic analysis and establish a 3D visual reconstruction model with actual colors. Then, the coordinate points of the landscape space staggered pattern are transformed into three-dimensional visual coordinate points to realize the reconstruction of landscape art space staggered pattern in patch area. The aerial landscape image of patch area is preprocessed and input into GPU to build a Gaussian difference pyramid model. The feature points of the patch area in the aerial landscape image are calculated by the parallel computing process, and the patch boundary in the aerial landscape image is determined. The landscape perimeter of the patch area was calculated according to the boundary. The experimental results show that the complete convergence time of the horizontal axis error and the vertical axis error is 2.13 s and 1.81 s, respectively, and the absolute error and relative error of the perimeter measurement are controlled below 0.60 m and 1.00%, respectively.

Our contribution includes the following three points: (1) Aiming at the problem of slow convergence in the parallel calculation of patch area landscape art index, a parallel calculation method of patch area landscape art index based on land cover data was proposed
(3) e experimental results show that the complete convergence time of the horizontal axis error and the vertical axis error is 2.13 s and 1.81 s, respectively, and the absolute error and relative error of the perimeter measurement are controlled below 0.60 m and 1.00%, respectively
Summary
Patch area landscape art can be basically divided into two types. One is soft things, such as sky, sunshine, drizzle, wind, water, and trees [1]. e other is hard things, such as railings, walls, landscape architecture, and paving. E second is social attribute [4] It has a certain social and cultural connotation, has a viewing function, can change the environment and use function, and can use the connotation to trigger human inner reactions such as empathy, association, interest, and emotion, which is the so-called patch area landscape art effect. Monotonous, and straightforward and has no sense of hierarchy and the layout is unreasonable and loses beauty, it is nonunity At this stage, it is advocated to build patch area landscape, which can more effectively use the current needs without weakening the resources of future generations and can meet the sustainable development of the city. E parallel calculation method of patch area landscape art index based on surface coverage data used in this paper can maintain the landscape through planning and design. (3) e experimental results show that the complete convergence time of the horizontal axis error and the vertical axis error is 2.13 s and 1.81 s, respectively, and the absolute error and relative error of the perimeter measurement are controlled below 0.60 m and 1.00%, respectively
