【摘要】：本文以呼和浩特市为研究对象,对呼和浩特市的环境承载力进行评价研究。在此过程中,建立了相对科学的环境承载力评估指标体系,将大气环境、水环境、声环境三个环境系统综合起来考虑,选取了三大环境中几个代表性较强的环境质量指标作为评估指标,对呼和浩特市环境的相对承载力进行了评估和深入的分析,并在评估结果分析的基础上,依据国家环境质量标准,国内环评较好城市的环境质量状况,结合呼和浩特市污染物排放趋势进行分析,创新性地提出了适合呼和浩特市发展的政策建议。具体内容主要包括以下五个方面。首先,阐述了研究呼和浩特市环境承载力的理论意义和现实意义,梳理了国内外有关环境承载力研究成果,对本文环境承载力研究创新点和不足加以说明,为呼和浩特市环境承载力的评价研究提供理论基础。其次,阐述有关环境承载力相关的理论基础,对承载力的概念加以界定,对环境承载力的特征加以论述,并对环境承载力相关理论基础进行介绍,主要有可持续发展理论、环境库兹涅茨曲线理论、生态经济系统理论以及人口承载理论。然后,对所研究城市,呼和浩特市的经济情况以及环境状况进行详细介绍:经济状况主要从经济结构和经济增长状况阐述,环境状况主要从呼和浩特市自然环境特征、环境污染状况和造成环境污染的主要原因加以阐述。再次,根据科学性、全面性、区域差异性、可度量的等原则,构建环境承载力评估指标体系,在此基础上评述相关的环境承载力评估方法,选取适合本文的环境承载力评判方法,对呼和浩特市的环境承载力进行评价研究。在比较各种分析方法的特点之后选择功效系数法,选取环境评价类别的指标,然后通过对比指标的实际值与阈值的差值,确定各指标的权数与功效系数,将功效系数以各自权数为比重进行几何平均,即可以得到环境承载力的具体数值。最后,针对评估结果,对呼和浩特市环境承载力的结论进行分析,分析该市的水环境情况、声环境情况以及大气环境状况,依据国家环境质量标准,国内环评较好城市的环境质量状况,并结合呼和浩特市自身条件提出相关政策建议并对本文存在的能够进行进一步拓展的研究空间进行阐述。
[Abstract]:This paper takes Hohhot as the research object, carries on the appraisal research to the Hohhot city's environmental carrying capacity.In this process, a relatively scientific assessment index system of environmental carrying capacity is established, and three environmental systems, namely atmospheric environment, water environment and sound environment, are considered.Several representative environmental quality indexes are selected as evaluation indexes, and the relative carrying capacity of the environment in Hohhot is evaluated and deeply analyzed, and based on the analysis of the evaluation results,According to the national environmental quality standard, the environmental quality of better cities in China, and the trend of pollutant emission in Hohhot city, the paper puts forward some innovative policy suggestions for the development of Hohhot city.The specific content mainly includes the following five aspects.First of all, it expounds the theoretical and practical significance of studying environmental carrying capacity in Hohhot, combs the research results of environmental carrying capacity at home and abroad, and explains the innovation points and shortcomings of the research on environmental carrying capacity in this paper.It provides a theoretical basis for the evaluation of environmental carrying capacity in Hohhot.Secondly, the theoretical basis related to environmental carrying capacity is expounded, the concept of carrying capacity is defined, the characteristics of environmental carrying capacity are discussed, and the related theoretical basis of environmental carrying capacity is introduced, mainly the theory of sustainable development.Environmental Kuznets Curve Theory, Eco-economic system Theory and population bearing Theory.Then, the economic situation and environmental situation of the city, Hohhot, are introduced in detail: the economic situation is mainly described from the economic structure and economic growth, and the environmental situation is mainly from the natural environment characteristics of Hohhot.The situation of environmental pollution and the main causes of environmental pollution are expounded.Thirdly, according to the principles of science, comprehensiveness, regional difference and measurable, the index system of environmental carrying capacity evaluation is constructed, and the relevant assessment methods of environmental carrying capacity are reviewed.The environmental carrying capacity of Hohhot city is evaluated by selecting the method of environmental carrying capacity which is suitable for this paper.After comparing the characteristics of various analytical methods, we select the efficacy coefficient method, select the index of the environmental assessment category, and then determine the weights and efficacy coefficients of each index by comparing the difference between the actual value of the index and the threshold value.The specific value of the environmental carrying capacity can be obtained by geometric averaging the efficiency coefficient with the weight of each weight.Finally, according to the assessment results, the conclusion of the environmental carrying capacity of Hohhot city is analyzed, and the water environment, sound environment and atmospheric environment of the city are analyzed, and according to the national environmental quality standard,The environmental quality of better cities in China is evaluated and the relevant policy suggestions are put forward according to the conditions of Hohhot and the research space which can be further expanded in this paper is expounded.
