Soil Chemical Properties of Different Forest Types in Xinjiashan Mountain
摘要
Abstract
The soil basic chemical properties of nine different community types in Xinjiashan Mountain were studied to provide elementary data for matter circulation of forest ecosystem and forest vegetation programming. Soil samples were collected in representative standard plots (20 mX25 m) using diagonal stationing method, and their basic chemical properties were assayed. SPSS software was used to analyze and compare the soil nutrients in different forest types and communities. The results indicated that soil pH and organic matter among different community types were significant different; soil pH and organic matter among different soil layers were significant different; soil pH in nine different community types was slightly acidic, ranging from 4. 75 to 6. 22, soil pH in the surface layer was higher than the sublayer. Within the same forest type, the content of soil organic matter in the surface layer was higher than the sublayer. Soil total nutrient in Pinus armandii was the lowest in nine community types. Correlation analysis showed that total nitrogen, the contents of organic matter, alkali-hydro nitrogen and total phosphorus in different types of forests were significantly and positively correlated; alkali-hydro nitrogen, the contents of organic matter and total phosphorus were significantly and positively correlated; soil pH and total nitrogen were significantly negatively correlated; the correlation between available phosphorus and total nitrogen was not significant.关键词
