在瓦房店市耕地地力调查和相关资料收集与整理的基础上,采用GIS技术、层次分析法、模糊综合评价法等,对瓦房店市北部5个乡镇的耕地地力进行了评价。结果表明,瓦房店市北部5个乡镇1等地占4.70%;2等地占32.61%;3等地占17.24%;4等地占30.59%;5等地占12.97%,6等占1.88%。结合当地的几种主要的土地利用类型进一步分析得出:果园、菜地和设施农业用地主要集中在1、2、3等地,地力较高,具有较大的生产潜力;旱地主要为4、5等地,说明旱地生产力水平普遍较低。因此,在旱地田间管理上必须重视使用有机肥,培肥地力,提高作物产量,促进农业生产的发展。
Based on the collection and arrangement of cultivated land fertility in Wafangdian City and using GIS, AHP and fuzzy comprehensive evaluation, the fertility of cultivated land in five townships in the northern part of Wafangdian City was evaluated. The results showed that the first towns and villages in the northern part of Wafangdian City accounted for 4.70%, the second and third places accounted for 32.61%, the third and third places accounted for 17.24%, the fourth and third places accounted for 30.59%, the fifth and other places accounted for 12.97% and the sixth and other accounts for 1.88% %. According to the analysis of several main types of land use in our country, we can draw the conclusion that the agricultural land in orchards, vegetable fields and facilities are mainly concentrated in 1, 2, 3 and so on, which have higher geo-productivity and larger production potential. The main dry land is 4, 5 and other places, indicating that the productivity of dry land is generally low. Therefore, we must attach importance to the use of organic fertilizer in the field management of dry land, fertilize the land, increase crop yields and promote the development of agricultural production.
