The displacement of arid valley boundary indicates the mountain ecosystem's response to climate change. The arid valley boundary in the Upper Reaches of Minjiang River was developed based on SPOT images and field investigation. The trends of meteorological elements were conducted using the linear propensity estimation method, based on the data from five stations in the study area. Then, the meteorological elements' annual rate of change or linear tendency rate was spatially interpolated using the radial basis function. The spatial distribution data for the trends of the annual average temperature, annual precipitation, annual sunshine duration, annual average relative humidity, and annual evaporation was obtained. The dataset includes the following data in the upper reaches of the Minjiang River: 1) the arid valley boundary data in 1999 and 2013; 2) the climate variability data from 1999 to 2013; 3) the statistics on the arid valley boundary’s displacement and climate variability. The dataset is archived in .shp, .tif, and .xlsx data formats, and consists of 46 data files with data size of 6.34 MB (Compressed into one file with 2.59 MB). The analysis paper based on the dataset was published in ISPRS International Journal of Geo-Infromation, Vol. 6, No. 5, 2017.
