Enzymes for soil stabilization in China were firstly used for road construction in 1995. Some experiences were obtained, but there were some problems with the works too. The present advancements on the study and application of enzymes for soil stabilization in China are introduced in this paper. The environmental protection value, e- conomic efficiency, and the problems are analyzed in the application and development of enzymes for soil stabilization. It is cited that enzyme as a soil stabilizer have been used to improve the strength of com- pressed soil, by the test for comparing strengths of soil stabilized by conventional stabilizers (anhydrate lime, Portland cement), Perma- Zyme 11X. The implications for future investigations are given.Key wor ds: Soil stabilization, Enzymes, The Present Advancement on the Study目前用于土壤固化的“酶制剂”一般是具有高浓度蛋白质和多种有机化 合 物 的 复 合 液 体 制 剂 ，以 下称为“土壤固化酶”。该制品无毒，无污染，口尝 鼻闻均有微甜味。现在国际上尚无统一的制造或 应用标准规范 [ 1 ] 。美国于 20 世纪 80 年代逐渐将 土壤固化酶应用于筑路、筑堤、筑坝、垃圾填埋处理、基础加固等领域，取得一些与传统土壤固化材料（如：石灰、水泥和沥青等）不同的效果，
