In order to study a certain influence of the land productivity of different soil types on ecological service value, according to the status quo of land use in Huailai County, soil type map and field survey results, the soil type area is used as the evaluation unit, and the grain yield of Hualai County in 2012 is based on the grain yield, the number of land use types in the soil type areas of Huailai County from 1992 to 2012, and the differences in land productivity in different areas, as well as the value of ecological service and the information entropy index of functional structure of land ecological service were quantitatively analyzed. The results showed that the land use change was featured as the slow increase of forestland,construction land and garden land, and the decrease of cultivated land and unused land. The distribution of grain yield was decreasing from northwest to southeast, and the land productivity decreased in the order:the anthropogenic-alluvial soils > moisture soil > paddy soil > cinnamon soil > skeleton soil > aeolian sandy soil > brown soil; ecological service value decreased in general from the north and south mountainous hilly area to the middle basin, the ecological service value of cinnamon area maximum was 1.260×109 yuan/year, the paddy soil area is the smallest, and ecological service value of the paddy soil area was 5.615×105 yuan/year, which were mainly supported by woodland and garden. The information entropy index of Hf in the brown soil area, coarse soil area, irrigated soil area, sandy soil area and paddy soil area were 0.32, 0.65, 0.34, 0.82, 0.86, respectively, indicating that the land use degree in these areas were relatively orderly and structurally strong, which was beneficial to the development of production activities. The Hf of cinnamon soil and tidal soil area were 1.04, 1.68, respectively, suggesting that the land use degree of this area was poorly ordered, the structural stability was weak, the health degree of the land ecosystem was low, which was not conducive to the development of the production activities. The extent of land use in the region remains stable as a whole.
