Problems solved by technology

[0003] At present, developed countries have carried out a lot of research work on visual landscape evaluation. Compared with foreign countries, my country's visual landscape environmental impact assessment work started relatively late, and the relevant research is mostly concentrated in the fields of urban planning, landscape garden design and road landscape ...

Embodiment Construction

[0026] Visual landscape evaluation area: The Ming Tombs are located at the southern foot of Tianshou Mountain in the northwest suburb of Beijing, with an area of ​​about 40km 2 In the north of the mausoleum area, the main peak of Tianshou Mountain is used as a barrier, surrounded by Dongmang Mountain and Xihuyu on the left and right, and there are Longshan, Hushan and other small tombs corresponding to the south. The direction of the mausoleum area faces south and backs north, and the road into the mausoleum is located at the southern edge of the mausoleum area. There is a huge white marble archway 1km away from the entrance of the mausoleum area, which is the sign of the entrance of the mausoleum area; There are Longshan and Hushan respectively. Longshan (222.5m above sea level) is located on the east side of Dagongmen, and Hushan (236m above sea level) is located on the west side of Dagongmen. The Stele of Divine Merit and Virtue of the Changling Mausoleum of the Ming Dynast...

Abstract

The invention provides a GIS (geographic information system)-based quantitative evaluation method of visual landscape influence and relates to the fields including landscape ecology, the GIS and urban planning. Based on the GIS, the quantitative evaluation is performed; an effective method to reduce the visual landscape influence is provided to solve the technical problem of determining the maximum ecological land area in the urban development. The technical scheme includes 1, establishing a digital terrain model according to basically topographic data, and generating a three-dimensional display image; 2, selecting sensitive landscape viewpoints; 3, analyzing exposure degree of the viewpoints; 4, analyzing visual distances; and 5, analyzing the influenced sensitive points, evaluating section lines among buildings in a site, and providing a layout plan of shield greening. In this way, the visual landscape environmental influence is evaluated in an objective and quantitative manner, and practicability in building and maintenance of the visual landscape sensitive areas including natural protection areas and historical cultural relics and remains is achieved.

Description

technical field [0001] The invention relates to the fields of landscape ecology, geographic information system (GIS), urban planning, etc., and is an effective method for carrying out quantitative evaluation of visual landscape environmental impact by using GIS as the main means, and obtaining corresponding measures for mitigating visual landscape impact. Background technique [0002] The tense relationship between man and land is one of the worldwide problems that mankind is currently facing. With the rapid development of urbanization and economy, the contradiction between man and land has become more prominent. Some projects that may have adverse effects on visual landscape have to be built in visually sensitive areas such as nature reserves, historical and cultural relics, scenic spots, and forest parks. In or nearby, in order to avoid unnecessary losses and irreparable regrets caused by construction projects to natural, historical, cultural and tourism resources, and to ...
