Abstract：[Background] Climate change and its linkage effect are the main ecological environment problems faced by all human beings. This study aims to clarify the impact of karst rocky desertification and climate change on regional climate, to reveal the law of precipitation change under the influence of climate change and rocky desertification, and to provide scientific reference for the ecological environment conservation and restoration of rocky desertification areas in China.[Methods] Based on the daily precipitation data of 6 stations in typical non-karst area and karst rocky desertification area of Yunnan province from 1959 to 2017, the change regulation of precipitation characteristics under the synergistic effect of climate change and karst rocky desertification was analyzed by linear tendency estimation and Mann-Kendall non parameter test.[Results] 1) The average change rate of precipitation in the karst rocky desertification area was -38.36%, which was higher than -11.34% in the non-karst area. 2) The number of rainfall days at all stations in the study period showed a decreasing trend, and the average reduction range of rainfall days in karst rocky desertification area was -0.225 d/a, which was larger than that in non karst area (-0.118 d/a). 3) The proportion of moderate rain level (average 34.04%) was the highest in non-karst area and karst rocky desertification area, while the rainstorm level (average 15.08%) was the lowest. Heavy rainfall especially rainstorm showed an increasing trend in the study period, especially in the rocky desertification area. 4) The longest duration of drought in non karst and karst rocky desertification areas is increasing. However, the average increase rate of rocky desertification in the karst area was 0.097 d/a, which was larger than that of 0.030 d/a in the non-karst area. 5) Excluding the slight increasing trend of the longest continuous precipitation time in Mengla station in non-karst area, the decrease rate of karst rocky desertification area was greater, with an average of -0.031 d/a.[Conclusions] Under the synergistic influence of climate change and rocky desertification, the change of precipitation characteristics in karst rocky desertification area is greater, and the situation of water resources will be more severe in the future.
