摘要：With the deepening of people's understanding of new energy, geothermal has become more and more "hot." The abundant geothermal resources of Henan Province will be an important resource pillar for the future economic growth of the Central Plains[1]. However, the vigorous development and utilization of geothermal resources will largely affect the soil structure. Through the data analysis of Luoyang A area, the influence of temperature change on soil structure was studied by using control variables and single factor experiment. The results showed that: with the continuous development of geothermal resources in Luoyang A area, the total amount of microbes, organic carbon and total nitrogen in the soil would chang with the increase of temperature.Among them, the number of microorganisms growed faster with the increase of temperature and reached the highest value up to 40 °C. As the temperature continuing to rise, the number of microbes growed slowly or on a downward trend.In order to avoid the influence of temperature changes on the soil structure, it is recommended to put insulation materials around the wellhead and the reservoir to prevent the lowest loss temperature from exceeding 30 °C or 3 wells alternating every other quarter[2].
