The Construction Of Environmental Impact Assessment Of Regional Development - Line And Two Belts "in Guanzhong Region," For Example

Regional exploitation and construction has been an important mode, which we carry into execution to realize the sustainable development of regional society and economy. Through exploiting lands on a large scale, we enhance and improve the regional economic configuration and structure as well as the overall arrangement of the industrial dimension. So that the regional economic strength has also been enhanced. However, during this course, due to the uncertainty and complexity of our exploiting acts, we are boosting the disorder of regional environment and make the ecological environmental problem become more and more outstanding. Guanzhong area as the important region in Shaanxi province especially in the hole west, the construction of the "one string and two belts " is not only the turning point of the development of the economy, but also the fatal act which will help Shaanxi province to realize the aim of building itself the economic strong province in the west. But the changes of population, industry, urbanization, the utilization of resources and environmental impact etc in one string and two belts will influence the regional ecological and living environment greatly. During the regional construction and exploitation, EIA of single project can't recognize the environmental problems fully and adopt reasonable actions against it, so it also hardly guarantees the sustainable aim of the whole region. Therefore the REIA of this region not only have the important scientific signification but also have the applied value.Based on the academic study of the radical tenet, estimate tenet, estimate means as well as technically route etc. of the REIA, from the point of the ecological environmental problems in Guanzhong area, by analyzing of the actuality of regional environmental quality, based on the theory of Regional Environmental Bearing Capacity (REBC), the thesis works out the models of computation and assessment of REBC, at the same time, the thesis evaluates the Ecological Satisfaction Degree and forecasts the let-out quantity and tendency of main pollution in Guanzhong area of 2005 and 2010,including the let-out quantity of industrial exhaust gas, sulfur dioxide, industrial waste water, uping to scratch of the industrial waste water, industrial solid castoff and living garbage. Wherefore, from the point of view of region and omnidirection, the thesis studies the sorts, characters, dimensions and the intensities etc. of the environmental infection during the construction of the "one string and two belts". At last the thesis puts foreword the countermeasures and measures in the whole Guanzhong area which lay particular stress on the rational utilizing of naturalresources, the quantity control of contaminations, the construction of environment as well as the rational overall arrangement of productivity, and aimed at harmonizing the relationships between the development of regional economy and the protection of environment. Through these studies, we get the following:(a)Aiming at the actual situation of the multiple system of nature, society and economy in Guanzhong area, based on the connotation and extension of Environmental Bearing Capacity, the connotation of regional environmental relative remainder rate and methods of computation are put forward in the thesis, then we get the environmental relative remainder rate of EBC in Guanzhong area;(b)Based on the meaning of Sustainable Development, from the point of view of human-oriented idea, Ecological Satisfaction Degree is applied to measure the developing condition of the regional ecological system in Guanzhong area;(c)According to the present and historical situation of pollution in Guanzhong area, the thesis not only sets up the temporal serial models of the main contamination, but also forecasts the let-out quantity of main pollution in 2005 and 2010 and checks up the relativity;(d)Based on the above conclusions, the countermeasures of environmental protection and regional space exploitation are put forward; It is also pointed out that the key points of...
