 The Chiang Haidebet Plateau is an essential water conservation region in Asia, but it is affected by various factors including human activity, climate, and vegetation. To better understand the spatiotemporal patterns of water conservation on the plateau, we use the INVEST model to calculate the water yield and select the most accurate remote sensing evapotranspiration data available. We then analyze the spatial and temporal variations of water conservation in each ecological zone and climate zone division and detected the factors affecting water conservation on the plateau using the geodetector method. Our results show that the overall water conservation decreased from southeast to northwest and that precipitation, evapotranspiration, and NDVI all have a positive correlation with water conservation. Additionally, the precipitation factor had the greatest impact on the spatial differences of water resource governance while the slope factor and the interaction between each factor improve water conservation.
