Natural Elements On Dalian City Human Settlement Impact Study

Human survival environment is the biggest influence on human factors in the variousenvironmental factors are natural elements. Living environment in a city as a unit it is someelement of the city out of a range of areas. In human development and construction tended tobe first in a new residential area planning and design, they will first consider the local naturalenvironment and social culture conditions, various construction affairs often takes objectivegrasp area actual situation as the prerequisite. The first consideration in evaluating habitabilityto form the natural elements of the natural environment and the distribution of the populationelements. City people human population of the city residential area are mostly the natureunder the influence of the natural elements with the most suitable for residential area havecertain differences, affect the elements of population distribution in addition to natural factorsand economic factors, social environment factor, political conditions, national macroeconomicregulation and control, history and so on. Geography the study of the earth’s surface is themost frequent human activities most closely layer and human relations. While the city ishuman activities on earth are the most active and interact relationship is the strongest. Sohuman to urban geography studies from the very early, and therefore got rapid progressivedevelopment of the urban geography.Dalian urban living environment of the natural suitability study is usually based onChina’s living environment in the natural suitability evaluation model of residentialenvironment index HEI model for evaluation and calculation, and assess the effects of themodel of the living environment generally has four main natural elements (terrain condition,vegetation, climate, hydrology condition), and frequent crustal activity in recent years, theauthor will join the evaluation system of geologic factors will also be included atmosphericpollution degree. Above all when to Dalian climate factor evaluation using fuzzymathematical method to determine the temperature and humidity factor is human settlementenvironment of Dalian city most affected by two factors. On this basis, it will simplyinflunced by the living environment suitable planning under the influence of physicalgeographical elements.This article is "the north bright pearl" Dalian, for example, on the basis of the Dalian citynatural conditions to establish a practical evaluation system, on the basis of the analysis ofclimate factor and using the fuzzy mathematics method, fuzzy mathematic evaluation systemanalyses its influence on living environment and development in Dalian, and according to thecorresponding data using GIS and Map Info technology will Map into the analysis of the data and results. And conclusion based on the evaluation of the city living environment status quohope can impact on the future urban planning and development as a reference.
