江西省内丘陵山地红壤非耕地主要有天然阔叶林、人工杉木林、人工马尾松林、人工油茶林和荒地。经过对这些非耕地土壤进行大量面上调查和定位研究后发现，除天然阔叶林外，这些非耕地土壤的退化现象极为普遍，其主要表现形式为：土壤剖面的逆向发育、土壤质地突变、土壤养分状况和土壤物理性状的恶化。研究同时表明，导致土壤产生退化的主要原因为：１）林业生产过程中林木更新和营林技术粗放，２）林地投入少，３）陡坡开垦，４）人为采薪对地表有机物层的破坏。最后，文中提出了防治丘陵山区红壤非耕地土壤退化的相应对策与措施
There are mainly natural broad-leaved forests, Artificial Chinese fir forests, Artificial Masson pine forests, Artificial Camellia forests, and wasteland in red soil of hilly and mountainous areas in Jiangxi Province. After extensive surface investigation and location studies on these non-cultivated soils, it is found that the degradation of these non-cultivated soils is extremely common except for natural broad-leaved forests. The main manifestations of these non-cultivated soils are: reverse development of soil profile, abrupt change of soil texture, Soil nutrient status and deterioration of soil physical properties. The research also shows that the main reasons leading to soil degradation are: 1) extensive tree regeneration and silviculture techniques in forestry production; 2) less investment in forest land; 3) reclamation on steep slopes; and 4) destruction of surface organic matter layers caused by artificial salaries. Finally, the paper puts forward the corresponding countermeasures and measures to prevent and control soil degradation of red soil in non-cultivated area in hilly mountainous area
