Study On Ecological Environment Impact Of Daocheng Airport

The Daocheng civil airport in Aden is located in China’s biodiversity conservation better Haizi Shan Hengduan Mountains region, the airport has in the vicinity of Haizi Shan Forest Park National Nature Reserve, the proposed airport regional biodiversity is relatively rich, its construction and operation could have on the surrounding ecological environment and biological diversity has certain negative influence. The main ecological environmental problems:high altitude, poor natural conditions, plant growth period short, fragile ecological environment, natural vegetation is damaged, the short term it is difficult to recover, even irreversible. The ecological environmental impact assessment is the feasibility of the project evaluation is one of the main content.This research will be based on the field investigation and remote sensing methods combined, according to the regional ecological environment situation:the natural environment, climate, soil, soil erosion, by analogy with the field survey, the specific case analogy, image measurement, expert advice, the method combined with the model prediction. Select the appropriate analogy object selection may focus on analog investigation content data survey, field monitoring or investigation, landscape ecological survey method, the public participate in the investigation method, analogy analysis, statistical analysis, single factor analysis and comprehensive analogy, analogy analysis, alternative analogy analysis a survey analysis method to range around the airport in land use, vegetation, land animals and plants resources and ecological sensitive area through detailed investigation and evaluation, including the types of ecological system and evaluation, land uses the current situation and evaluation of plant, animal, situation and evaluation of resources, all kinds of ecological sensitive area profiles, present situation of ecological environment quality and evaluation, the main ecological environment make detailed analysis and evaluation. And on this basis, combined with the proposed airport engineering properties, prediction and evaluation of airport construction on regional land use, vegetation, biological resources and ecological sensitive zone of influence, from the protection of biodiversity and maintaining regional ecological balance angle, puts forward the corresponding protection countermeasure and the measure, with a possible reduction due to engineering construction for the regional ecological environment and biological diversity brought adverse effect, for the project construction and management to provide a scientific basis.Research results show that:the construction activity may have on wild animal produce minor shock, but does not reduce its number, not on the protected area animal impact. The landscape heterogeneity increases, a strip-shaped landscape with cutting, thickets, meadow landscape continuity, integrity is reduced, the degree of landscape fragmentation increases, so that the original natural landscape affected by human disturbance. Through scientific reasonable planning and design and construction sites and camp, strict control of construction activities, can reduce the construction process on surface vegetation destruction. Sichuan Haizi Shan National Nature Reserve from the proposed airport is2--3km, and airport runway direction generally parallel with the protected area planning scope, plane landing does not preserve, not on the protected area of animal protection activities influence.
