摘要: 土地利用变化是全球环境变化的重要组成部分,其可以直接影响到土壤性质的变化。本研究通过中亚热带山区天然林、人工林(用材林和经济林)、次生林、农业用地(橘园和坡耕地)等7种典型土地利用方式土壤性质的研究,结果表明:土地利用变化后土壤有机质和全氮含量下降幅度分别达到52.2%~81.8%和57.9%~172.6%;同时土壤容重增加,pH值升高。而土地利用变化对土壤全磷、全钾的影响的规律较为不明显。综合比较中国区域土地利用变化对土壤性质变化的影响,其中20~25°N纬度带土壤物理化学性质变化幅度最大。

Abstract: 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.
