阜南县耕地地力评价与中低产田改良

为了掌握阜南县耕地地力以及中低产田分布情况并研究相应的改良利用措施，以阜南县第二次土壤普查以及测土配方施肥等数据文本资料为基础，在地理信息系统与计算机技术的支持下，对阜南县耕地生产潜力进行划分，并在此基础上根据《全国中低产田类型划分与改良技术规范》（NY/T310-1996）以及阜南县实际情况对阜南县中低产田类型进行二级系统划分。结果表明，阜南县耕地地力可以划分为5个等级，并在此基础上将中低产田划分为三大类型，即干旱灌溉型、渍涝潜育型和渍涝排水型。并针对性的提出各中低产田以及土壤改良的对策与建议。

Cultivated Land Fertility Evaluation of Funan County and the Improvement of Middle-and-Low-Yielding Fields

In order to master the farmland productivity and the middle-and-low-yielding fields distribution of Funan County and study the relative improvement measures to use,in this paper,making use of the Funan County’s text materials,such as the second time soil census and soil testing data,supported by GIS and computer technology,its cultivated land’s productive potentials were divided,and then,according to the grade standard of national low yield farmland type partition and improved and Funan County’s actual situations,the Funan County’s middle-and-low-yielding fields were divided by level 2 type system.The results showed that the farmlands’productivity could be divided into five levels,and the middle-and-low-yielding fields could be divided into three types： drought irrigation type,stains waterlogged gleysols type and waterlogging drainage stains type.At the end of this paper,the targeted gain and soil improvement countermeasures and suggestions were put forward.
