| 摘 要： | 为了掌握阿克苏市耕地地力基本情况和科学指导农业生产,运用GIS技术和综合指数法对阿克苏市耕地土壤进行了地力评价与改良利用分区研究.结果表明,阿克苏市1,2,3级耕地面积占耕地总面积的63.81％,绝大部分耕地处于中上等水平,耕地生产潜力总体较高.地力等级相对较低的耕地主要障碍因素是土壤盐渍化,其次是土壤中有机质、全氮、碱解氮、有效锌和有效锰的含量相对较低.利用评价结果对阿克苏市现有耕地进行改良利用分区,并提出相应的改良利用措施,实现了耕地改良利用分区的定量化.

| Abstract: | In order to understand the basic fertility condition of cultivated land and scientifically guide agricultural production in Aksu City of Xinjiang Wei Autonomous Region,China,fertility evaluation and improvedpartition of cultivated land are conducted by applying GIS technology and comprehensive index method.Results showed that the first,second and third levels of arable land account for 63.81%of the total cultivatedland area.Most of the arable land is in the middle and upper level with high land productivity potential.Themajor obstacle factor for the low level of arable land is soil salinization.Low contents of soil organic matter,total nitrogen,available nitrogen,available zinc and effective manganese are also less important obstacle factors.Improved utilization division of arable land in Aksu City is carried out by using this evaluation resultand improved utilization measurements are suggested,which helps making utilization division on arable landquantitatively. |
