珠三角土壤酸化数据集(1985和2010)

1985年珠三角32个县大气污染监测数据，观测指标内容：县名、土地利用方式，地质、大气污染数据(二氧化硫，氮氧化物，酸雨，氨根离子，硝酸根离子，施氮肥量，土壤有机质)；2010年珠三角32个县大气污染监测数据，观测指标内容：县名、土地利用方式，地质、大气污染数据(二氧化硫，氮氧化物，酸雨，氨根离子，硝酸根离子，施氮肥量，土壤有机质)；1985年珠三角32个县0-20cm土壤pH数据均值，观测指标内容：土壤pH。数据量为2376条。

This dataset contains three segments of environmental and geospatial monitoring data for 32 counties in the Pearl River Delta (PRD): 1. Air pollution monitoring data from 1985, with observation indicators including county name, land use type, geology, and air pollution metrics: sulfur dioxide (SO₂), nitrogen oxides (NOₓ), acid rain, ammonium ions (NH₄⁺), nitrate ions (NO₃⁻), nitrogen fertilizer application rate, and soil organic matter. 2. Air pollution monitoring data from 2010 for the same 32 PRD counties, with an identical set of observation indicators as the 1985 dataset. 3. Mean soil pH values for the 0-20 cm soil layer of the 32 PRD counties in 1985, with the sole observation indicator being soil pH. The total number of records in this dataset is 2376.
