Comprehensive analysis of effective utilization of resources and environmental protection in Baotou city

With the effectively control of the point source pollution, non-point source pollution has become the most serious pollution source in our country. In addition, the agricultural non-point source pollution control has become the most important part of the environmental protection. By referring to related journals, this article makes a comprehensive analysis on definition, characteristics, mechanism, harm and prevention countermeasures of agricultural non-point source pollution.

Real Costs

Since 2005, expenditures on research, development and technological work (R & D) have been allocated in the structure of investments in non-financial assets. The absence of methodological developments on a comprehensive analysis of indicators of environmental and economic efficiency does not allow us to clearly determine the real costs of creating a system of rational nature use and environmental protection. In order to, at least approximately estimate the necessary level of investment in the restoration of the environment, it is necessary to conduct a study of the relationship between investment and environmental activities through the interrelationship between the concepts of "investment" and "capital investments".

This paper studies the influence on environment provoked by the construction and operation freeway under marketization mode. Through the comprehensive analysis of influence to environment which is from marketization development mode freeway’s environmental protection investment, quality of project, devastation to natural and cultural environment, toll station operation. We found that there exists a mass of damages to natural and cultural environment, and the characteristic of marketization development mode results in derivative damages and repetitive pollution. At last, this article puts forward some solutions such as strengthening constitutional construction, enhancing supervision, completing and adjusting the marketization development mode.

The Impact

Abstract The area of environmental protection concern minimises the impact that technical objects have on the environment. Usually the most effective way of protecting the environment is to influence the source of the problem. For this reason studies are conducted to modify the construction of machines, power machines in particular, so as to minimise their impact on the environment. In the case of environmental protection from noise it is most convenient to carry out measurements in an anechoic chamber. Unfortunately, this is possible only in very limited circumstances. In all other cases measurements are performed using an engineering method or the survey method, both of which are described in the standards and by taking into account the so-called environmental corrections. The obtained results are burdened with greater error than those of measurements in an anechoic chamber. Therefore, it would seem advantageous to develop a method of obtaining similar and reliable results as those in an anechoic chamber, but in a reverberant field. The authors decided to use numerical modelling for this purpose. The main objective of this work is a comprehensive analysis of the numerical model of a laboratory designed for acoustic tests of selected power machines. The geometry of a room comprising an area of analysis is easy to design. The main difficulty in modelling the phenomena occurring in the analysed area can be the lack of knowing the boundary conditions. Therefore, the authors made an attempt to analyse the sensitivity of various acoustic parameters in a room in order to change these boundary conditions depending on the sound absorption coefficient
