Abstract：[Purposes] In order to achieve scientific management and eective utilization of land resources，detailed geochemical surveys of land quality have been conducted in diferent regions.This survey not only covers a wide geographical area，but also employs advanced analytical methods aimed at comprehensively and accurately assessing the quality status of land.[Methods] We conducted in-depth research on land resource management，food security，targeted poverty alleviation，and ecological civilization construction in Shilao Street，Longshan County as the research area.In this survey，a detailed evaluation of the land quality was conducted for a scale of 000.By collecting a large number of soil samples and applying professonal geochemical analysis techniques，rich data and information have been obtained.[Findings] The overallqualityof land in Shilao Street is good， with high-quality land occupying 6 8 . 7 1 % of the total area. These lands have fertile soil， good drainage performance，and suitable ecological environment，providing unique conditions for agricultural production.Meanwhile，medium level land also accounts for 2 9 . 2 1 % of the assessed area，although slightly inferior to high-quality land，it still has great development potential.[Conclusions] These data not only reflect the content and distribution of various elements in the soil，but also reveal the physical and chemical properties of the soil，providing astrongbasis for evaluatingland quality
