Considering the limitation of the present crop grouping method, we think crops should be classified into three groups (crop for social, economic or ecological benefit) according to its leading function in agricultural ecological economic system. Based on systematic analySis of the characteristics and strategies for higher yield and better benefit to each of the three groups, we pro~ a new crop disposing strategy in this paper.

本文针对现行作物分类法的局限性,运用农业生态经济系统的功能性原理,提出一种新的作物分类法,以作物生产过程所表现的主体功能为依据将作物分成三大类型即社会型、经济型和生态型,并对每一类型作物的基本特性和增产增效对策进行了系统分析。在此基础上,提出了区域性生态农业建设中农田作物的合理配置的新策略。

The grey system relevant analysis method was used to study 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 among all comprehensive factors. The farming, forestry, animal husbandry and fishery are unbalance in development. The capability of the farmers' individual invests is low. According to the analysis of grey-relation between the agricultural modernization level and total output value of agriculture, the dosage of chemical fertilizer has the greatest contribution to the total output value of agriculture. The power-driven irrigation and drainage equipments, the effective irrigation area and the built electromechanicafl wells have less relation to the total output value of agriculture because of improperness or lowness of utilization. According to the analysis of grey relation between farm product yield and the total output value of agriculture, the output of maize makes the greatest contribution. Combined with the actual circumstances, the measures for improving agriculture were put forward.

To analyze and study energy flow of rural ecological economic system is necessary to improve the systematic structure and comprehensive benefit.Through the analysis and study of five typical ecological models of Zhongzhuang village where plant industry is primary in the agricultural ecological economic system so as to explore resonable rural ecological economic system.The proportion of organic energy is high in the systematic energy input,amount to 88%~94%,the organic fertilizer and feed are primary in the organic energy input,the organic energy input exceeds inorganic energy input,it shows that the agricultural produce and the mechamical extend are low.Analyzing the energy flow of the plant industry system,which shows the energy input is low and the output is high and the cultivation industry system in which the energy input is high and the output is low.On the whole,the agricultural ecological economic system is the system that the energy input exceeds output.Moreover,the energy input is in opposite proportion to the output.It shows that the energy input level of agricultural produce in the region is low.

能流是生态系统的基本功能,是系统结构和功能的综合反映。通过对半干旱退化山区彭阳县崾岘乡中庄村农村生态经济系统的能流进行分析研究,以期探讨出合理的农村生态经济系统结构。通过对中庄示范区具有代表性的5种生态模式进行分析研究,该区农业生态经济系统是以种植业为主的。有机能在系统的能投中占的比例较大,达到系统总投能的88%~94%,有机能的投入中主要以有机肥和饲料为主,有机能的投入远大于无机能,反映了该地区的农业生产水平低下、机械化程度较低。从种植业系统的能流分析来看,是一个能量低投入与高产出的系统,养殖业系统是一个能量高投入与低产出的系统。总体来看,中庄村的农业生态经济系统是一个能量投入大于产出的系统,而且,能量的投入和产出呈反比关系,说明该区农业生产的能量投入水平还很低。
