采用灰色关联分析法研究了闽北山区农业生态系统结构因素之间的关系。全村工农业总收入主要受农业发展的影响 ,其中农业收入由种植业、养殖业、林果业、渔业等组成 ,相互间关联度分别为0 .8575、0 .92 77、0 .92 52和 0 .912 8。对作物总产量影响最大的是劳力、灌溉面积、耕地总面积以及无机和有机肥投入等 5个因素。因而应当进一步合理调整生产结构 ,以利于充分发挥山区型生态农业的优势。 Gray relational analysis was used to study the relationship between agroecosystem structural factors in mountainous areas of northern Fujian. The total industrial and agricultural income of the village is mainly affected by the development of agriculture. The agricultural income consists of planting, breeding, forestry and fruit industry, fishery and so on, with the correlations being 0.8575,0.92 77,0.92 52 and 0 .912 8. The greatest impact on the total crop yield is labor, irrigated area, the total area of ​​cultivated land and the input of inorganic and organic fertilizers. Therefore, we should further rationalize the production structure so as to give full play to the advantages of mountain-type eco-agriculture.
