| 摘 要： | 以昌江黎族自治县(昌江县)为研究区,借助于空间分析手段,分析区内第2次土壤普查期间到2009年土壤耕层土壤pH的时空变异特征,并阐述其主要成因.结果表明,在气候、地形、母质、植被等自然因素共同作用下,20世纪80年代研究区土壤pH在西北到东南方向上有逐级降低的特征.区内2009年土壤pH值低于第2次普查期间,且空间变异度变小,平均值由6.0降至5.8；土壤pH分布受施肥、工矿等人为生产活动的影响,原有的空间分布格局有所改变,主要表现在昌化、海尾、乌烈等地土壤出现酸化特征.

| Abstract: | Changjiang Li Autonomous County in Hainan was used to study the distribution of soil pH in arable land of the 1980s and 2009, and analyzed the main influence factors of soil pH distribution based on geo-statistics and spatial analysis. The results indicated that the soil pH was gradually declined from northwest to southeast in the 1980s, and the distribution of soil pH was determined by natural factors mainly. The soil pH was 5.8 in 2009 and 6.0 in the 1980s. Soil acidification areas were mainly distributed in Changhua, Haiwei and Wulie. The anthropogenic factors, including the application of chemical fertilizers and pollution of mining activities, were the main reason of arable soil acidification in the study area. |
