[Objective] The aim of this study is to explore the intensity of human activities in urban and rural areas, as well as the temporal and spatial evolution of economic and ecological effects of human activities in urban and rural areas in order to provide certain theoretical support and decision-making guidance for comprehensive and quantitative evaluation of human activity mechanism, ecological civilization construction and socio-economic development in urban and rural areas. [Methods] The intensity and threshold evolution of human activity in urban and rural areas of Guizhou Province were studied by building models of human activity intensity index, human activity intensity threshold and human activity effect in urban and rural areas. [Results] From 2010 to 2018, the intensity of human activities in rural areas of all cities in Guizhou Province decreased(7.57%~28.57%), and the intensity of human activities in urban areas increased(22.72%~124.83%). The intensity of human activities in urban areas was greater than that in rural areas. The minimum and maximum thresholds for rural human activity intensity in all cities have generally decreased, but most cities exceed the maximum threshold(1.02~1.62 times). The land system in mountainous areas bore the impact of higher human activity intensity in rural areas. The threshold of urban human activity intensity in all cities and cities had increased. In 2018, the intensity of urban human activity had approached the highest threshold(0.940~0.997 times), and the urban human-land system was under great pressure. The economic effects of human activities in unit towns and the ecological effects of human activities in unit rural areas in all regions show an increasing trend(annual average growth rate 8.60%~13.53%), and the ecological effect of human activities in unit villages was more significant than that of human activities in cities and towns(2.24~14.84 times). [Conclusion] Although the intensity of human activities in rural areas of Guizhou Province had weakened and the intensity and threshold of human activities in cities and towns had increased, the intensity of human activities sustained by the land system was relatively high, and the economic and ecological effects of human activities in unit villages and towns had increased and changed. In the future, we should continue to explore the system of measuring the intensity of human activities in cities and towns.
