The Study On The Temperature And Humidity Effective Radius And The Space-time Variational Laws Of DaQing Longfeng Everglade

With the development of urbanization, urban wetland has become an increasingly important issue. Based on the review of related literatures, the concept of urban wetland was addressed, and its ecological service functions were analyzed. It is usfull for wetland protection and restoring.It has lots of ecological and social service functions. One is that urban wetland could improve urban air quality. In this paper, the study took Daqing longfeng wetland as the study area. Using instruments to conduct site surveys,the effective radius of temperature and humidity in the area was acquired. From the micro-climate in terms of wetlands, we know that it is important for city to protect wetlands. Also ,the study provide a theoretical basis.Fixed point in space 100 meters from the wetland edge to the urban. The observations indicators include temperature, relative humidity, wind speed, wind direction, solar radiation and atmospheric pressure, etc; In a week, everyday observations was conducted every two-hour from 8:00 am to 16:00 pm; the data of the observation points at different time slots was to attain, using partial correlation analysis and multiple regression analysis method to deal with data, analysing the main factors of the temperature and humidity effective radius in Longfeng wetland of Daqing city. And it established the regression equation between the factors and the effective radius and analyzed the spatial-temporal variations about the temperature and humidity effective radius of the urban wetlands.This study on wetland temperature and humidity-effective radius carries out a preliminary exploration , and it is the basis of research for the next step in the area reserved of urban wetlands.
