皖南山区土壤酸化趋势研究——以宣城市广德县为例
|
摘要
皖南山区土壤出现了酸化趋势,本文以具有代表性的宣城市广德县为例,通过将最新一轮土壤调查与第二次土壤普查的土壤pH值进行对比分析,从总体、主要土壤类型、农用地类型以及空间分布4个方面,系统地研究了土壤酸化的趋势及其影响因素,并结合区域实际情况,提出了相应的土壤酸化防治对策。
Soil acidification is evident in Southern Anhui. It took Guangde County of Xuancheng City as a typical region in this paper to analyze the change tendency of soil pH value by comparison of pH data in 1981-1985 and 2006-2007 from different aspects (i.e., general region, major soil types, major agricultural land types and spatial distribution) systematically. And in the end, the effective measures to reduce soil acidification according to regional actual situation were put forwards.
