RESEARCH ON LANDSCAPE ECOLOGICAL SYSTEM OF HIGHWAY BASED ON NEURAL NETWORK

摘要

The expressway is a combination of the natural environment and an artificial structure. The construction of an expressway produces enormous negative impacts on the natural and human landscape along its route, exacerbates the contradiction between population, resources and the environment and adds the pressure of highway ecosystem. With the deepening of the concept of sustainable development, how to improve the proportion of landscape, environmental psychology and ecological elements, and build a harmonious environment system of "man-vehicle-road" is an important theme that engineers face in current expressway construction. An initial analysis of an ecological index of the expressway landscape was set up in this paper. The research selects the ring road in southwest of Zhengzhou city, Henan Province as the project example, summarizes the elements involving various aspects in the ecological landscape system of the highway, constructs a scientific highway landscape ecological research system, and uses the BP neural network method to systematically analyze the example.
