Abstract：In order to investigate the effect of different stand type on the soil nutrient in Maotai water functional areas，the soil nutrient of three kinds of coniferous forests were studied, such as Pinus massoniana Lamb forest, Cupressus funebris Endl.forest, Pinus massoniana Lamb and Cupressus funebris Endl. mixed forest. The results showed that: there were some differences in the average soil nutrients composition between coniferous forests, in which OM, Avail. N, Avail.K of Cupressus funebris Endl. forest＞ that of Pinus massoniana Lamb and Cupressus funebris Endl. mixed forest ＞that of Pinus massoniana Lamb forest, while Avail.P of Pinus massoniana Lamb and Cupressus funebris Endl. mixed forest ＞that of Pinus massoniana Lamb forest ＞ that of Cupressus funebris Endl. forest, Total N of Pinus massoniana Lamb and Cupressus funebris Endl. mixed forest ＞that of Cupressus funebris Endl. forest ＞that of Pinus massoniana Lamb forest. In addition, statistical analysis showed that OM, Avail. N and pH of three stand types were significantly different（P＜0.05), the Total N and pH of Cupressus funebris Endl. forest, Pinus massoniana Lamb and Cupressus funebris Endl. mixed forest were significantly differences（P＜0.05), while Avail. P and Avail. K of three forest types were not significantly differences （P＞0.05). Correlation analysis showed that for Total N, OM, Avail. N and pH there was a great correlation between each other, and Avail. K was significantly related with Total N, OM, Avail. N, Avail. P. Moreover, Referring to the evaluation criteria of soil nutrients, Avail. P and OM of the three forest types was very rich, above the medium level, Avail. K was lower than the medium level, while others’ was between the abundance and deficiency.
