Abstract
Global land-use and land-cover pattern has greatly changed in the past years, which exerts considerable direct or indirect bearing on the climate change at both regional and global scales. The purpose of this study is to analyze the impacts of land-use changes on regional climate by linking them with temperature and precipitation trend using spatio-temporal analysis and statistical method. The relationships between the observed changes in land-use and temperature parameters in Khoy from 1987 to 2017 were examined. The results showed the following features: (1) The use of built-up areas in Khoy city has increased by 19328 hectares (20.74%) in a 30-year period. (2) The trend of changes in the two temperature parameters in the period 1987-2017 in Khoy is upward and increasing, but not very upward for the average temperature. (3) There is a positive correlation between minimum and maximum temperature ranges in this city with the increase in the number of built-up areas during the study period, but the correlation for the average temperature, was negative
