广东海岸带土壤与底质类型分布图（1:150万）

广东省海岸带土壤与底质类型图分陆域和海域两个部分。根据地理国情监测土壤分类标准，在实测数据基础上开展工作，陆地土壤类型共分为15个土类，包括山地草甸土、水道土、沼泽土、滨海砂土、潮土、石灰土、实质土、砖红壤、粗骨土、紫色土、红壤、酸性硫酸土和黄壤；海域部分，以海域表层沉积物数据为准，对海岸带范围内的底质类型划分，得到10种表层沉积类型，包括砂质砾、砾质砂、粗砂、中砂、细砂、粉砂质砂、黏土质砂、砂-粉砂-黏土、黏土质粉砂以及粉砂质黏土。

The soil and substrate type map of the coastal zone of Guangdong Province is divided into two sections: terrestrial and marine. This map was developed based on field-measured data in accordance with the soil classification standard for national geographical conditions monitoring. For the terrestrial part, a total of 15 soil groups are identified, including Mountain Meadow Soil, Channel Soil, Bog Soil, Coastal Sandy Soil, Fluvio-aquic Soil, Calcareous Soil, Substantial Soil, Laterite, Skeletal Soil, Purple Soil, Red Soil, Acid Sulfate Soil, and Yellow Soil. For the marine part, substrate types within the coastal zone are categorized using marine surface sediment data, resulting in 10 surface sediment types, including Sandy Gravel, Gravelly Sand, Coarse Sand, Medium Sand, Fine Sand, Silty Sand, Clayey Sand, Sand-Silt-Clay, Clayey Silt, and Silty Clay.
