摘　　要：概括土壤铵固定及固定态铵释放研究的历史及现状，重点介绍台湾土壤固定铵的研究成果，包括土壤粘粒不同层面电荷、粘粒表面铵离子交换选择性、粘粒表面净零电荷点和净表面电荷、表面电荷非均匀性等对铵固定的影响。The history of soil ammonium fixation and release since 1930's is summed up and the research result of soil ammonium fixation mechanism about soil electronic properties in Taiwan since 1990 is introduced in this paper.The effect of different layer charge of clay, of net surface charge of soil clay, of point of zero net charge (PZNC), of surface charge heterogeneity of swelling clay minerals, and ammonium ion exchange selectivity of clay surface on ammonium fixation are studied. The results of the research could be used as an example for the researchers in the relevant aspects.
