Effects of Land Use/Cover Change on Soil Properties in Mid-subtropical Mountainous Area of Southern China
Land use/cover change (LUCC) is one of the most important components of global environment change and it can affect soil properties directly. The influence of LUCC from natural forest, artificial forest (timber forest and economic forest),secondary forest, agricultural land(orchard and arable land)on bulk density(BD) ,soil organic matter(SOM) ,soil total nitrogen(TN),total phosphorus(TP) ,total potassium(TK) and pH values was investigated in mid - subtropical mountainous area of southern China. The results showed that: Under the influence of LUCC, the contents of SOM and TN decreased by 52. 2% -81.5% and 57. 9% - 172. 6% , respectively; while the values of BD and pH increased greatly. The law of the influence of LUCC on the variation of TP and TK isn' t obvious. The most significant change of soil properties caused by LUCC in China happened at the latitude of 20- 25 °N.
