In this paper, 18 towns of Jinyun were analyzed. Natural conditions (average elevation, relative height difference, and gully density), socio-economic status(population density, and per capita disposable income), characteristics of soil erosion (area ratio of soil erosion, area ratio of soil erosion above moderate), and the present state of soil and water conservation, (vegetation coverage) were calculated. Self-organizing Feature Maps (SOFM) was used for soil and water conservation regionalization. Through the analysis of the 18 towns in Jinyun, two first-order classes and five second-order types were identified. The results showed that the classification results were consistent with the actual characteristics, and the feasibility of using SOFM for classification of soil and water conservation regionalization has been demonstrated through this study.
