2015-2018年南水北调（中线）水源地耕地和城市周边土壤样品及属性数据

2015-2018年南水北调（中线）水源地耕地和城市周边土壤样品及属性数据，在耕地和城市周围选取91个典型区采集土壤样品，测定土壤基本物理性质（容重、机械组成）、土壤基本化学性质（土壤pH、有机质、全N、全P）、土壤重金属含量（包括As、Cd、Cr、Cu、Hg、Ni、Pb、Zn）。数据集共3640条记录。

Soil samples and their attribute data from arable land and urban periphery in the water source area of the Middle Route of the South-to-North Water Diversion Project (2015–2018): A total of 91 typical sampling sites were selected around arable land and urban areas for soil sample collection. Basic physical properties of soil (bulk density, mechanical composition), basic chemical properties (soil pH, organic matter, total N, total P), and heavy metal concentrations (including As, Cd, Cr, Cu, Hg, Ni, Pb, Zn) were determined. This dataset contains a total of 3640 records.
