Abstract

Shallow geothermal energy(SGE),as a new kind of clean and renewable energy,can be used to solve energy shortage,emission of greenhouse gas,etc.On the basis of in-situ thermal conductivity test,the reserve condition of SGE in Guiyang was analyzed,and thermal parameters of the region in association with test data of stratum thermal effects were obtained.According to analytic hierarchy process(AHP),suitability classification was carried out for SGE from soil.Furthermore,we calculated the total heat power and the potential of development and utilization of SGE in Guiyang.Results show that,on the supposition of full utilization of SGE from soil in Guiyang,in the winter,we can supply heating for area of 1.95×10⁸ m²;while in the summer,we can cool the identical area.In light of this,it is very significant to promote the utilization of SGE in Guiyang.

Key words
