| 摘 要： | 在对长春市二道区耕地土壤野外调查、社会统计和土壤室内分析、各类相关图件数字化的基础上,采用GIS技术、层次分析法、模糊评价和综合指数分析等方法,对长春市二道区耕地地力进行了评价。结果表明,长春市二道区的耕地为21 099.58 hm2,可划分为6等地。其中,3等耕地主要受质地影响,4等耕地受地貌影响程度大,5等耕地受腐殖质层厚度和土壤养分影响,6等耕地受地貌和侵蚀影响较大。

| Abstract: | Based on the field investigation,social statistics,laboratory analysis and the digitalization of map and table of cultivated land in Erdao District of Chcngchun City,by means of GIS technology,analytic hierarchy process,fuzzy evaluation and composite index analysis,the cultivated land fertility of Erdao District in Changchun City was evaluated in our paper.The results showed that the cultivated area of Erdao District in Changchun City was up to 25 923.73 hm2,dividing into six cultivated land productivity grades.In addition,the third cultivated land was mainly affected by texture,and the fourth cultivated land was mainly influenced by landform,while the fifth cultivated land was affected by humus thickness and soil nutrients,while the sixth cultivated land was influenced by landform and erosion. |
