摘要
以福建省耕地为评价对象,借助GIS与数学模型对福建省秋花生用地适宜性进行评价。结果表明,福建宜秋花生用地面积75.67万hm2,占耕地总面积的55.18%。全省宜秋花生用地质量总体一般,其中最适宜秋花生用地面积12.60万hm2,适宜面积55.56万hm2,分别占宜秋花生用地总面积的16.66%和73.43%。秋花生最适宜区用地资源主要分布在漳州、泉州、福州、龙岩、莆田和厦门市,合计面积12.24万hm2,占最适宜区总面积的97.14%;荚果发育期的低温、灌溉条件总体较差,以及耕层浅薄是福建秋花生用地的主要限制因子。
Taking cultivated land in Fujian as object, it was assessed the suitability of land resources for autumn peanut by means of GIS technic and mathematic models. The result indicated that the total areas of suitable land resources for autumn peanut were 75.67 ×10^4 hectares, which accounted for 55.18% of the areas of cultivated land. The land quality for autunm peanut was total ordinary in Fujian. The areas of the most suitable land resources for autunm peanut were 12.60 × 10^4 hectares , more suitable land resources for autunm peanut were 55.56 × 10^4 hectares, which respectedly accounted for 16.66%, 73.43% of the areas all the suitable cultivated land forautunm peanut. The land resources for autunm peanut were mainly distributed in six regions of such as Zhangzhou, Quanzhou, Fuzhou, Nongyan Putian and Xiamen. The total areas were 12.24 × 10^4 hm^2, which accounted for 97.14% of the areas of the most suitable regions. Low＇air temperature during fruitage developing , total bad conditions of irrigation and shallow plowland were main controlling factors of land for autunm peanut cultivation in Fujian.
