摘要
为了掌握泰州市姜堰区耕地地力以及各等级耕地分布情况,对中低等级土壤改良利用提出对策和建议,在县域资源管理信息系统支持下,按照姜堰区耕地地力评价指标体系和方法对耕地生产潜力进行划分,全区耕地地力共分为4个等级,通过对耕地地力进行评价,得出中低产田分布区域、面积和障碍因素,并在此基础上科学提出土壤改良利用措施,旨在进一步提高耕地地力,提升姜堰区的农业生产力。
In order to grasp the farmland productivity and the distribution of each level cultivated land of Jiangyan District in Taizhou City,the countermeasures and suggestions for low and medium grade soil improvement using were put forward. Under the support of county territory resources management information system,according to Jiangyan District farmland productivity evaluation index system and method,the farmland production potential were divided, the whole district farmland productivity were divided into 4 grades.Through the fertility evaluation of the farmland,the middle- and-low-yielding fields distribution area, area and obstacle factors were concluded, and on this basis the soil improvement measures were put forward, to further improve the farmland productivity,improve agricultural productivity of Jiangyan District.
