Abstract: Support vector machine is a new machine learning technique developed on statistical learning theory.Because of its excellent learning performance，this technology has become the new research hotspot in the field of international machine learning.In this paper，the principle of support vector machine is introduced，and an integrated assessment model for regional land resource eco-security is established based on it.Test result indicates that it is feasible to apply support vector machine to assess the level of regional land resource eco-security.

Key words: eco-security, land resource, support vector machine, multi-classification
