Embodiment 1

[0036] In the construction of ecological green space, using the comprehensive evaluation method of landscape visual impact based on GIS of the present invention, it can be based on the principle of science and rationality, on the basis of science, to pursue artistry and interest, and actively play the participatory nature of the public , so that the public participates and makes residents actively care about the protection, management and application of their habitat landscapes. Practice has proved that the method of the present invention can make residents realize that landscapes play an important role in social life, cultural fields and economic life, and can actively participate in The discussion of landscape evaluation is conducive to experiencing self-ecological education and landscape historical and cultural inheritance. This comprehensive method can combine the public and landscape analysis and design experts, so as to maximize the rationality and science of the experts,...

Abstract

The invention provides a landscape visual impact comprehensive evaluation method based on a GIS. The method includes the following steps of establishing an objective evaluation function, establishing an evaluation object impact factor set, establishing the weights of impact factors, listing an impact factor fuzzy evaluation matrix, achieving landscape visual impact evaluation through the GIS and generating a multi-dimensional display graph. The method that the evaluation object impact factor set and the weights of the impact factors are established, in combination with an analytic hierarchy process and a fuzzy evaluation method, a position variation function and a semi-variogram are adopted for analysis, the landscape visual impact evaluation is achieved through the GIS, and the multi-dimensional display graph is generated is adopted, the landscape visual impact can be comprehensively and objectively evaluated, the evaluation effect is very ideal, all the factors and opinions of all crowds can be comprehensively considered, data are stored and compared through the GIS, the high reliability of landscape visual evaluation is achieved, and the guiding effect on landscape design is achieved.

Description

technical field [0001] The invention relates to the technical field of landscape evaluation and design, in particular to a comprehensive evaluation method for landscape visual impact based on GIS. Background technique [0002] Since the 1980s, with the rapid development of my country's economy, the city has taken on a new look and the quality of the urban environment has been greatly improved. However, compared with developed countries, there is still a big gap between my country's urban landscape and real environment. Reflection There are still many problems in urban landscape construction in recent years, such as local urban environment, landscape has improved, the overall urban environment and landscape quality has declined, many destructive constructions have appeared, forming new visual landscape pollution, urban landscape reconstruction, Overemphasis on protection, emphasis on surface, ignorance on substance, eagerness for quick success, and destruction of many historica...
