In order to study the distribution and influencing factors of available boron in tobacco-growingsoils，and to provide theoretical basis for the nutrient management of tobacco-growing soils and the development of characteristic and high-qualitytobacco leaves，294 tobacco -growing soils were collected in LongshanCounty，and the spatial distribution of available boron in tobacco-growing soils and its influencing factors were studied by geostatistics and multivariatestatistics.According to thedescriptive statisticalresults，the available boron content of tobacco -growing soils in Longshan County wasabundant，with anaverage value of 0.792mg/kg，but the variation waslarge，and the suitable sample proportion was33.33%.From the resultsof statistical analysis，the available boron content in northern and southeastern Longshan County wasabundant，while that inWestern Longshan County was relativelyscarce.Available boron increased firstly and then decreased with rising ofelevation；soil available boron was positively correlated with exchangeable calcium and exchangeable magnesium； soil available boroncontent increased with the increase of soil organic mattercontent；soil available boron content increased with the increase ofsoilpH.Tobacco -growing soil in Longshan County had abundant available boroncontent.Elevation，soil texture andtype，organicmatter，pH and exchange Ca and Mg could all affect the content of soil availableboron.And the regional differenceof soil available boron wasgreat.It was suggested that boron fertilizer should be applied in the western boron -deficient areas.
