酸雨对土壤生态系统影响的研究进展

酸雨是人类当前面临的最严重的环境问题之-,并目益成为土壤学和生态学研究的热点.现有的大量研究表明,酸雨对土壤生态系统的功能特性,包括土壤的盐基离子以及重金属与微量元素的淋溶、土壤营养、土壤酸化、土壤微生物数量及其活性、土壤缓冲性能、土壤对酸雨的敏感性、土壤结构、土壤矿物风化等方面均会产生一定的影响.本文就酸雨对土壤生态系统特性的影响研究进展进行了综述,旨在为其他学者今后开展相关研究提供参考.

Advancements in Research on Impact of Acid Rain on Soil Ecosystem: A Review

Acid rain, as one of the major environmental problems man is confronted with, is becoming a hot spot in the study of soil science and ecology. So far, most related researches and achievements have showed that acid rain has certain impact on functions of a soil ecosystem, such as leaching of soil base-exchangeable ions, heavy metals and microelements, nitrogen, contents of sulfur and phosphorus nutrients, soil acidification, population and activities of soil microbes, soil buffer capacity, soil sensitivity to acid rain, soil structure and weathering status of soil minerals, and so on. A review was presented of advancements in the researches on impacts of acid rain on functions of soil ecosystems, with an attempt to provide other researchers involved in the acid rain area with some information for reference.
