Indentification Of Environmental Impact And Assessment Of Landscape Pattern For The Highway Engineering

The paper study the indentification of environmental impact and assessment of landscape pattern for highway engineering, discuss the variance in environmental impact and assessment of landscape pattern. Based on environmental impact assessment, the paper bring up the measure of zoology recovery and pollution prevention for release environmental impact, they can offer foundation of engineering decision, can advising engineering environmental protection design and environmental management of engineering construction or operation. We want to maximumly control environmental impact, hope achieve the unification of economic benefit,social benefit and environmental benefit. These are the paper's intention.The paper choose the case study of Shennongjia Distrect, follow the track from the theory study to demonstration analysis, from system regulation to polling analysis of model modality. Based on land use diversification, landscape ecology environmental impact indentification and correlation theoretical basis, used remote sensing and GIS , mathematics statistics, landscape analysis etc, the paper had analysed indentification of environmental impact and assessment of landscape pattern for highway engineering, had discussd the change of land using, environmental impact and landscape pattern, had analysed the regulation of their space-time conjugation. The resulting display: the environment losing of construction project mostly found expression in decrease of cultivated area, biomass loss for construction project forever occupation of land and temporary occupation of land. After engineering finished, the amount of all kinds of land type had come about diversification, the area of grassland, cultivated land and wood land had reduced, the building area had increased. The biomass and average productivity would decrease because of reduction of grassland, cultivated land and wood land area. Engineering construction bring about variance in region land use pattern, shall influence nature system of appraising region.The engineering would influence landscape pattern. Ground excavating, engineering occupation of land, rural settlement relocation of residents etc would change figure ,size, amount and spatial distribution and configuration of the landscape pattern plaque, corridor and groundmass.
