Abstract


In recent years, the quality of life and gradually improve healthy living environment is the pursuit of the goal , as an important indicator of the living environment - atmospheric environment has become increasingly attracted the attention of experts of different disciplines . Air anion concentration refers to the number of negative ions in the unit volume , it is one of the important indicators to measure the extent and quality of fresh air . Through the observation of negative air ion concentration as well as the regression equation analysis , in-depth study of the changes of negative air ion concentrations in a variety of weather conditions , and the use of a large number of observational data validation and experimental . This paper describes the generation and function of the concentration of negative ions in the air , anion observation methods and the main principles of various meteorological factors on the degree of influence of the concentration of negative ions , and then use the stepwise regression equation analysis software , as well as a large number of observational data , also anion the horizontal and vertical distribution of the concentration has been studied, and thereby draw conclusions . Difficult to change due to weather conditions and geographical environment in nature , in the artificial , this paper analyzes the fountain and urban greening to change the size of the negative air ion concentration , eventually pointed to changes in the environment can directly affect the changes of negative air ion concentration has certain research value . Finally, the situation of the impact of environmental change on the negative air ion concentration in urban planning as well as the further utilize the door edge science aeroanion some suggestions . How to plan breaths of air anion District to construction to rich aeroanion for ecological health tourism facilities to increase the coverage of urban green space and needs to be further research into the health science education . With the advancement of technology and in-depth research , multidisciplinary cooperation is the inevitable development of the subject , and the negative ions medicine, physics , biology , health , and other subjects of mutual cooperation and common development of a science .
