| 摘 要： | 黄红壤是皖南地区区域经济发展的一个重要自然资源，但不合理的土壤利用与管理阻碍了该区的农业持续发展。笔者在评价皖南地区的气候条件、植被资源、土壤生态系统的基础上，讨论了当前皖南黄红壤地区土壤生态系统中存在的问题，并提出了黄红壤改良的对策与措施：（1）实行农林复合生产，优化土地利用方式，以提高水土资源的利用率，（2）消除土壤“酸、瘠”等限制因子，提高土壤生产率；（3）增施有机肥，平衡施用化肥以补充土壤养分，调控养分循环；（4）建立适宜的耕作制度，改善土壤性质，防止水土流失，提高生产效率和经济效益。

| Abstract: | The yellow-red soil is an important natural resource for regional economic development of south Anhui,but the unrea-sonable use and management of the soil in this district hindered the sustainable growth of agriculture. on the basis of evaluating the climate,vegetative resources,soil ecosystem,in this paper the existing problems in soil ecosystem were discussed and the strategies and methods of amelioration of the yellow-red soils were presented: 1) conducting agroforestry production and opti-mizing the land utilization to increase the use efficiency of water and soil resources ; 2) delimiting the limiting factors such as acidity and low fertility of the soil to enhance the productivity ; 3)adding the organic mannure, balanced chemical fertilizer to re-plenish soil nutrients for control and management of nutrient cycling ; 4)establishing the suitable cropping system to improve the soil properties,prevent soil erosion and increase the productivity and economic efficiency of cultivation. |
