This study aims at exploring the methods to regulate the land function and evaluate the ecological performance of major function oriented zones at sub-country scale. Huangyang Lake Group was taken as the study area and the employed methods include remote sensing image interpretation, land use classification, land use transfer matrix and gravity center model. The results showed that: 1) the proportions of land used for ecological purposes, residence and production decreased, stabilized and increased, respectively, in Huayang Lake Group area from 1990 to 2010, the main changes were the conversion of lake to cultivated land, inland tidal flats, reservoir pits and construction land; 2) gravity model showed the sharpened imbalance of the spatial distributions of forestland, grassland and reservoir, and the gradually increased imbalance of the spatial distributions of inland tidal flats, construction land and farmland; 3) the proportions of the ecological land of restricted and optimized development zones met the requirements, the ecological land of prohibited development zone needed to be improved; 4) the proportions of the ecological land of most towns had been decreasing, especially Gaoling and Chengling; 5) the ecological performance evaluation weights of prohibited, restricted, key and optimized development zones were 1, 0.8, 0.3 and 0.2, respectively. In conclusion, the land regulation based on ecological, living and production land classification and ecological performance evaluation system at town levels provided a reference for implementing major function oriented zoning at sub-county scales. However, the implementation of the land function regulation of major function oriented zones requires the coordination of government departments. The indexes and weights of ecological performance evaluation system need further investigations.
