| 摘 要： | 浅层地温能利用前景广阔。据实际勘查资料和测试数据,采用层次分析法及C-A分型方法对乌鲁木齐市北部城区进行浅层地温能定量适宜性分区评价。结果表明,地下水源热泵适宜,较适宜区面积196.35 km^2,分布在第四系卵砾石厚度适中、含水层富水性好、单井涌水量1 000~5 000 m^3/d、地下水径流速度0.1~0.2 m/d的地带;土源热泵适宜、较适宜区总面积284.50 km^2,分布在黄土、粉土、砂砾卵石厚度大于30 m的地带,研究区其它地方不适宜浅层地温能的建设。评价结果对该区浅层地温能开发利用具有良好的指导作用。

| Abstract: | The shallow geothermal energy has a broad prospect. Based on the actual exploration data and test data, this paper uses the analytic hierarchy process and C-A classification method to evaluate the quantitative suitability of shallow geothermal energy in the northern urban area of Urumqi. The evaluation results show that the suitable and suitable area of ground water source heat pump is 196.35 km^2, which is distributed in the zone with moderate thickness of Quaternary gravel, good water-rich aquifer, 1000-5000 m^3/d single well water inflow and 0.1~0.2 m/d groundwater runoff velocity. The total area of ground source heat pump is suitable and suitable for284.50km^2, which distributes in the areas of loess, silt, gravel thickness more than 30m. The other places in the study area are not suitable for the construction of shallow geothermal energy. The evaluation results have good guidance for the development and utilization of shallow geothermal energy in this area. |
