This thesis takes Hohhot as research object to evaluate the environmental bearing capacity. During this process,a relatively scientific evaluation index system is set up,and the atmospheric environment,water environment,the sound environment system of the three considered together.The index system selects some representative environmental quality indexes as the evaluation indexes,then makes an evaluation and in-depth analysis on the relative environmental capacity of Hohhot,combination of the environmental quality of the Hohhot,the state environmental quality standards,as well as the environment quality of these good domestic utban during the EIA,according to the environment demands of two-oriented soeiety,puts forward a new environmental quality standards to meet the two-oriented society construction innovatively.The main research contents are as follows.Firstly, the study of environmental carrying capacity Hohhot theoretical and practical significance, combed the research results on environmental carrying capacity, environmental carrying capacity will be explained in this article and inadequate research innovation, evaluation of environmental carrying capacity for Hohhot provide a theoretical basis.Secondly, elaborate theoretical basis for environmental carrying capacity related to the definition of the concept of carrying capacity, environmental carrying capacity of the features to be addressed, and introduces the theoretical basis of environment-related capacity, mainly theory of sustainable development, environmental Kuznets Kuznets curve theory, ecological and economic systems theory and the theory of the population carries.Then, for the study of the city- Hohhot economic and environmental situation in detail: the economic situation is mainly explained from the economic structure and growth conditions, environmental conditions, mainly from Hohhot natural environment characteristics, environmental conditions and cause environmental pollution The main reason to elaborate.Again, according to the scientific, comprehensive, regional differences, measurable principles, building environmental carrying capacity evaluation system, review the relevant environmental carrying capacity assessment on the basis of selected environmental carrying capacity evaluation method for the article, environmental carrying capacity study to evaluate Hohhot. After comparing the characteristics of a variety of analytical methods to select the efficiency coefficient method, select environmental assessment category indicators, then the difference between the actual value and the threshold contrast indicators to determine the weights of each index and the efficiency coefficient, the efficiency coefficient to each right The average number of geometric proportion, which can get specific numerical environmental carrying capacity.Finally, evaluate results, conclusions Hohhot environmental carrying capacity analysis and the water environment, the acoustic environment as well as the city’s air quality conditions, according to the national environmental quality standards, domestic EIA better quality of urban environment, and Hohhot combined make itself relevant policy recommendations and research of this article can be elaborated further expansion of space.
