Abstract: The Taklimakan Desert is a typical arid area. Due to the needs of production and life, a total of 2 km 2 of constructed green land (hereinafter referred to as CGL) has been formed in the sand dune, resulting in the uniform underlying surface of the desert having been changed, which has led to the change in the near-surface energy distribution pattern and the formation of a local climate of the CGL that is obviously different from that of the desert climate. Therefore, it is necessary to study the varied interval of the threshold of meteorological factors and the regional climate characteristics of the CGL under the background of desert. The main results are as follows. Firstly, from sunrise to noon, the increasing rate of temperature in natural sandy land (hereafter, NSL) was higher than that in CGL, and the opposite results occurred between noon and sunset. The peak temperature of CGL was 2 h later than that of NSL. At night, the temperature at the boundary of the CGL was generally higher than that of the NSL and the central area of the CGL. In addition, the results show that under the combined influence of underlying conditions, local circulation and small terrain, the CGL (middle) daily range of temperature > NSL (west) > CGL (east) > CGL (west). The positive temperature change period of CGL was significantly shorter than that of NSL in all seasons. However, temperature inversion occurred at night in all seasons. The intensity of the temperature inversion was strongest in winter, with a maximum temperature difference of 12.8 °C, followed by autumn, spring, and summer, with a maximum difference of 6.4 °C. Secondly, the wind speed in the daytime was higher than that at night, and the wind speed in NSL was higher than that in CGL. In summer, if the average wind speed of the NSL was quantified as 1.0 m/s, the wind speed lapse rate reached 30% at the boundary of the CGL. Similarly, in the central area of CGL, the wind speed lapse rate reached 71%.
