摘　　要：By analyzing the climate records of Kunming from 1957 to 2016, Kunming’s average temperature has been found to be increasing in recent 65 years. The key problem lies in the temperature rise in recent 10 or more years by 0.4 ℃/10a and the annual range decrease at the same time, represented as the elevation of the lowest temperature and increasingly warmer winter in Kunming. With the warming climate, the precipitation has suffered a prominent fall, by 18.05 mm/a in the past 14 years. The relative humidity is in direct proportion to the precipitation, which explains less water and drier climate in Kunming. With “One increase and two decreases” of the three key climate indexes changes in Kunming in the past 65 years, this paper analyzed the necessity and general situation of the sponge city construction in the city, proposed the overall planning of sponge city construction at the macro level, selected the sponge technology based on the urban construction land types, and planned the regulation facilities based on the catchment area and green space structure. Moreover, the paper explored the sponge city planning at the meso level and the sponge city eco-engineering technology at the micro level.By analyzing the climate records of Kunming from 1957 to 2016, Kunming’s average temperature has been found to be increasing in recent 65 years.
