摘要/Abstract

摘要： 用灰色系统的关联理论对白城市生态农业经济系统的影响因素进行了分析. 在综合因素中，农业人口和耕地面积对农业总产值的影响最大；农、林、牧、渔发展不平衡；农民个人投资力差. 从农业现代化水平指标与农业总产值的关联度分析，化肥施用量的贡献率最大；农用排灌动力机械、有效灌溉面积、配套机电井等指标因水平较低或利用不当，贡献率较小. 从各种农产品产量和农业总产值的关联度分析，玉米的贡献率最大. 结合白城市的实际情况，提出促进农业发展的主要措施.

Abstract: The grey system relevant analysis method was used to s tudy the main influential factors of Agricultural Ecological-economic System in Baicheng city， the results show that the peasant population and agricultural acreage have the greatest influence on the total output value of agriculture amo ng all comprehensive factors. The farming, forestry, animal husbandry and fish ery are unbalance in development. The capability of the farmers’ individual i nvests is low. According to the an alysis of grey-relation between the agricultural modernization level and total output value of agriculture, the dosage of chemical fertilizer has the greates t contribution to the total output value of agriculture. The power-driven irriga tion and drainage equipments, the effective irrigation area and the built electr omechanicafl wells have less relation to the total output value of agriculture b ecause of improperness or lowness of utilization. According to the analysis of g rey relation between farm product yield and the total output value of agricultur e, the output of maize makes the greatest contribution. Combined with the actua l circumstances, the measures for improving agriculture were put forward.
