To quantitatively determine the effect of Xiluodu Reservoir on the temperature of the surrounding mountains, the temperature differences between various locations and the reservoir were calculated based on Landsat 8 thermal infrared sensor (TIRS) data. Elevation, slope, aspect, normalized difference vegetation index (NDVI), and visual field were selected as the impact factors, and the most significant grid size used to explore the effect of reservoir on the surrounding mountains was determined by spatial analysis and partial correlation analysis. The effect of the Xiluodu Reservoir on the surrounding mountains' temperature was then quantitatively studied while accounting for the effect of water surface width on temperature. The results are summarized as follows. The most significant grid size for determining the influence of Xiluodu Reservoir on the surrounding mountains' temperature is 90 m. The effect range threshold of the entire reservoir on the temperature of the surrounding mountains is approximately 600 m, and the partial correlation coefficient in each buffer area decreases gradually with increasing distance from the reservoir. The effect threshold of the reservoir on the temperature of the surrounding mountains is approximately 1,500 m in the head area with a water surface width approximately 1,000 m, but it is negligible in the tributary area where the width is approximately 60 m.

量化溪洛渡水库对周围山脉温度的影响。

为了定量确定溪洛渡水库对周围群山温度的影响，根据Landsat 8热红外传感器（TIRS）数据计算了各个位置与水库之间的温差。选择高程，坡度，坡向，归一化植被指数（NDVI）和视野作为影响因素，并通过空间分析和偏相关分析确定用于探索水库对周围群山影响的最重要网格尺寸。然后，在考虑水面宽度对温度的影响的同时，定量研究了溪洛渡水库对周围山脉温度的影响。结果总结如下。决定溪洛渡水库对周围群山温度影响的最重要网格尺寸为90 m。整个水库对周围山脉温度的影响范围阈值约为600 m，每个缓冲区的局部相关系数随着与水库距离的增加而逐渐减小。在水面宽度约为1,000 m的水头区域，水库对周围山脉温度的影响阈值约为1,500 m，但在宽度约为60 m的支流区域，该阈值可忽略不计。每个缓冲区的局部相关系数随着距储层距离的增加而逐渐减小。在水面宽度约为1,000 m的水头区域，水库对周围山脉温度的影响阈值约为1,500 m，但在宽度约为60 m的支流区域，该阈值可忽略不计。每个缓冲区的局部相关系数随着距储层距离的增加而逐渐减小。在水面宽度约为1,000 m的水头区域，水库对周围山脉温度的影响阈值约为1,500 m，但在宽度约为60 m的支流区域，该阈值可忽略不计。
