Abstract: In order to better target formula fertilization, the author studied soil fertility and soil regionalization of Eucalyptus plantation in Heyuan. The results showed that: (1) overall, the soil was serious degradation, serious compaction and the ventilation permeable ability was very poor of Eucalyptus plantation in Heyuan. Organic matter, total potassium, total phosphorus, hydrolysis of nitrogen and quick result of potassium were the middle level, while total nitrogen and available phosphorus were in the lack of level. (2) Organic matter, total nitrogen and hydrolysis of nitrogen of granite soil were in the optimum level, while trace elements of shale and sandshale soil are in the optimum level. Soil nutrients of second generation of budding forest were better than planting by stock. (3) In the end, Eucalyptus plantation were divided into good soil fertility areas (numbers were 3,4,9,11,12,15,19,22), medium fertility areas (1,2,8,14,16,1718,20,21) and poor soil fertility areas (5,6,7,10,13), soil nutrient contents were 3.546%-4.415% 2.742%-3.228% and 1.795%-2.590%.
