Abstract：Based on the key factors of large-scale ecological corridor formation from the perspective of wind domain, the minimum cumulative resistance model and ventilation benefit evaluation model were built. Taking Beijing-Tianjin-Hebei region as the study area, meteorological data, remote sensing and other basic geographical data were used to analyze the characteristics of near-surface wind field and identify the spatial pattern of ecological corridors. The multi-year average wind speed was 2.07m/s in the study area near ground. For winter, the multi-year average wind speed showed high values along the Zhangjiakou Dam-Beijing-Tianjin coastal area and low on both sides, and the prevailing direction was northerly wind. For summer, the multi-year average wind speed was high in the northwest and southeast, and low in the mid-east and southwest, and the prevailing direction was southerly wind. For winter, 34 social and economic sources were screened out, five first-level ecological corridors were identified, and their trend was from northwest to southeast or from north to south; seven second-level ecological corridors were identified, and their trend was mainly from west to east. For summer, 68ecological sources were screened out, five first-level ecological corridors were identified, and their trend was from southeast to northwest or from south to north; and six second-level ecological corridors were identified, and their trend was mainly from east to west. Five first-level north-south ecological corridors with a total length of 3073.04km and five second-level east-west ecological corridors with a total length of 1582.06km were selected by combining and simplifying the ecological corridors with better connectivity performance for winter and summer. They initially constructed the spatial pattern of “five vertical and five horizontal” ecological corridors in the Beijing-Tianjin-Hebei region.
