The purpose of this paper is to review recent 30 years research of China's land resource evaluation by using fuzzy mathematics methods. The results indicate that, since 1980 fuzzy mathematics methods have been applied to land resource evaluation, the relevant articles are not only distributed on many journals, but the authors are also scatterd. Especially, the major applied fuzzy mathematics methods are fuzzy comprehensive evaluation and fuzzy classification, and the articles using fuzzy comprehensive evaluation are 46% of the indexed papers, and the articles using fuzzy classification are 26% of the indexed papers. The method of fuzzy comprehensive evaluation is mainly applied in land suitability judgment, land quality evaluation and land sustainable development evaluation. The method of fuzzy classification is mainly applied to clustering region of land use condition and land resource evaluation. At the same time, the further application directions are the land resource evaluation, clustering, planning, decision making, forecast and control. When we use the fuzzy mathematical methods, we should pay attention to expressing the fuzzy concept rationally, utilizing multiple methods and innovating in practice.

Key words: fuzzy classification, fuzzy comprehensive evaluation, land resource evaluation
