Study On Characteristics Of Soil Respiration Under Stress City Impervious Surface

The modernization of city, greatly influenced the process and function of city ecological system. The atmospheric carbon dioxide increased because the changes in land use Every year. The soil respiration changes and the research of terrestrial ecosystem carbon cycle have been paid more and more attention. In this study, the city zone shape, surface shape, body shape of impermeable surface are the research object. And we adopt the research methods of field observation. Studying on the change of soil respiration and temperature in the variation characteristics. The main conclusions obtained are as follows:(1) Three types of artificial impervious surface of adjacent soil respiration has a significant effect on soil respiration rate of green space. Soil respiration showed a decreasing trend with the distance gradient.(2) Artificial impervious surface has a significant impact on adjacent to the soil temperature and moisture.Soil respiration was positively correlated with soil temperature, but negatively correlated with soil moisture content.(3) Effect of artificial impervious surface of different sizes on soil respiration of different degree.
