Soil available Zn is an important index for evaluating the nutritional status of soil.The precision fertilization of micronutrients can be achieved by clarifying temporal and spatial distribution characteristics of soil available Zn content inChina and taking effective measures to improve the soil available Zn content of soil types and regions of Zndeficiency.The data of this research are accessed from China Agricultural Eco-Station.The temporal and spatial distribution difference of soilavailable Zn content and the influence of different factors to soil available Zn content areanalyzed，like the soiltypes，landutilizations and soil physicochemical properties(soil organic matter，pH，availN，avail P，avail K and cation exchangecapacity).The resultsshow:1)Soil available zinc content in China is in the middle level as awhole，the distribution trend is south-high and north-low，east-high and west-low.The distribution of soil available Zn content has a good correlation withthe soil pH distribution，division of dry and wet areas and zonal distribution of soiltypes；2)In timeseries，soil availableZn content shows an upward trend from 2005 to 2015.3)Soil available Zn content has the significant difference betweendifferent soil types and land utilizations.Among soil types，the red earth and paddy soil have the higher soil available Zncontent than the others’，in contrast，soil available Zn contents of Aeolian sandsoil，Loessial soil and Meadow sandy soil are lower than others’.Among land utilizations，soil available Zn content of paddy field is significant higher than others；4)Among soil physicochemicalproperties，soil pH and soil organic matter content have a significant impact on soil availableZn content.In summary，among different soil types，Aeolian sand soil，Loessial soil and Meadow sandy soil need thesupplement of Zn fertilizer；among different land use patterns，the irrigated land and dry land should be emphasized thesupplement of Znfertilizer.Inaddition，the soil available Zn content can be improved by the adjustment of the soil pH and application of manure.
