闽北山区西瓯村农业生态系统结构因素的灰色关联分析

Grey Incidence Analysis on Structural Factors of Agricultural Ecological System in Xioupu Village of Northern Fujian.

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。

The relations among relative structure factors were studied through grey incidence analysis within agricultural ecological system in the hilly areas of northern Fujian.The gross income of industry and agriculture was mainly affected by the development of agriculture in the village.The agricultural income arose from such four industries as cultivation, breeding industry, forestrypomiculture and fishery,whose incidence was 0.8575,0.9277,0.9252 and 0.9128 respectively. Five elements which had utmost influence on the total yield of crops were labour, irrigation area, cropping field, input of inorganic and organic fertilizer. The production structure should be further reasonably adjusted in order to fully exert the advantages of ecological agriculture in hilly areas.
