| 摘 要： | 四川盆地紫色丘陵区的水土保持林低效化问题已较严重。研究了其土壤方面的成因。通过对土壤构造、土壤肥力特性、土壤结构性评价等研究，指出该区人工林地的土壤构造发育不正常，土壤腐殖质胶体积累量低。土壤结构质量差等林地土壤退化是土壤水土保持功能降低的主要原因。根据研究的初步结果，提出了相应的对策建议。

| Abstract: | Low efficiency of water-conservation forest had been a serious problem in purple hilly areas of Sichuanbasin. In this work, the soil genesis had been conducted. The conclusion that abnormal soil tectonics, low accumulatingsoil humus colloid and low soil structural quality were the main cause of debasing of soil water-conservation function, as well as some countermeasures, had been proposed after the study on soil tectonics, soil fertilizer features and assessment of soil structure in purple hilly region. |
