Ecological Environment Vicissitudes In Xi'an-Research And Analysis Of Natural Ecological Environment

The ecosystem city construction is a long-term the Jian huge mission, ecosystem city in Xian construction want basis condition and characteristic establishment of oneself in Xian correspond of development measure, direction.City construction can't again repeated list depend increment resources devotion to push development of old road, have to depend on science and technology progress, with ecosystem environment construction is point, construction resources economy type, ecosystem type city, keep economy and resources environment of moderate development.City is the mankind are in the process of turning into for several thousand years in the change rely for existence of environment, creator height of material civilization of concentration is 1 with artificial center of the unify of interaction, check and supervision and dependence constitute of the of the organism and natural environment and social milieu of the city life the body be a huge complications of society, economy compound eco-system.This topic is to include archeology, geography, city planning to learn, building learn, the history learn several cross of academics contents of etc. sex research and involve city in the meantime total programming, city slice area programming, ecosystem city construction, history cultural city protection etc. some level, therefore, the thesis be main research contents, project and measure to draw up to launch in manily the academics, manily the level cross.The topic research direction lay particular emphasis on at city ecosystem main factor in Xian-nature eco-system in main ecosystem main factor(the agriculture, forest, water fasten, city nature the view, city be green to turn, land make use of condition etc.) change of analysis research.Learn realm in the archeology, geography, history first, draw up to pass data investigation, sequence and space sequence in time two level collection sorting the region, ecosystem environment in Xian City in the loess plateau, pass in importance of ecosystem main factor of history cultural heritage and change process, acquaint with at macro view, big district, small district, part region four ecosystem environment on the level present condition, for after of research work launch to lay foundation;Secondly learn realm in the city planning, should research the city be total programming, city slice the area be whole programming, city ecosystem environment programming etc. several level, and to city point district(city construction of point, line, noodles) thorough of on-the-spot step to investigate investigation, pass total to the city fixed position, slice area development target, district reality demand of comprehensive research, study city ecosystem environment in Xian change and development present condition, pass a city land make use of, environment loading dint, ecosystem balance angle, environment capacity, anti-earthquake reduce disaster's etc. to in many ways face city ecosystem environment in Xian to carry on environment evaluation and valuation.Comprehensive to ecosystem environment history in Xian change summary etc. research result, for future city planning in Xian and ecosystem city construction provide foundation data and theories basis.
