The Analysis And Evaluation Of Microclimate For Rural In Northeast Cold Region

At present, the northeast cold region rural micro climate evaluation research is still in the blank stage,foreign evaluation system of existing village micro climate does not conform to the actual situation of our country。Microclimate evaluation has been enacted mainly for urban areas, are not suitable to region rural areas.The evaluation of micro climate for in northeast cold region is one of the issues of national project.The assessment is signficant to society and nature.Through to the northeast cold region climate characteristics and micro climate influence factors analysis, fully understand the status quo of the micro climate in the northeast cold, and based on the understanding of the northeast cold region climate background, the villages made a comprehensive and in-depth investigation of field visits, to nearly swallowed residents on the subjective questionnaire survey, at the same time using the relevant instruments to the outdoor microclimate environment objective data test, and the subjective and objective evaluation data collection and analysis. Combination of summary and micro climate assessment method for screening, selection can be used in the cold region in northeast China micro climate evaluation method, and on the basis of the northeast cold region village survey data, the inhabitants of the outdoor environment of the micro climate of the subjective evaluation and objective physical environment set up test data correlation, preliminary cold region of northeast China rural micro climate evaluation system is established.Papers creative work is mainly reflected in the following aspects:(1)Through the cold region of northeast China micro climate analysis of the present situation,the micro-climate impact factors and micro-climate evaluation model and method,and combined with the northeast cold region,warm winter cold and summer half of the characteristics of the selected is suitable for the northeast cold region village evaluation model of the micro climate, wind effect index(K), temperature humidity index(THI),and based on this, the northeast cold region micro climate research is divided into three periods: summer study period(Jun, Jul and Aug),study period in transition seasons,winter study period(Dec,Jan,Feb), the transition season study period is divided into cold season transition period(Mar Nov) warm study period in transition seasons in(Apr,May,Sep,Oct).(2) using interval estimation method,the statistical relationship between subjective and objective evaluation was established based on SPPS software,and is suitable for the northeast cold region level of micro climate combination evaluation model and evaluation standard.Evaluation: the wind effect index can effectively evaluate the northeast cold region in Jan,Feb,Mar,Nov,Dec micro-climate environment; Temperature humidity index can effectively evaluate the northeast cold region in Apr,May,Jun,Jul,Aug,Sep, micro-climate environmen.
