With index modle and from point of view of agrosystem engineering, the system analysis and system synthesis on the developmental dynamic state of 1978-1983's crop-culture and agroproduction of Guanghan county were made in this paper.The results are:The principal factor keeping up a steady increase in the index of crop-culture output value is crop,especially the rapid increase of unit area yield of cereals. Rape production is a superiority of Guanghan. There is a correlation between the increase of crop-cultural output value and the expanse of rape cultivated area. The appropriate increasing of rape area and the decreasing of wheat area is a suitable way for readjustment of relationship between food crop and economic crop. Therefore, the readjustment of agricultural structure can take effect with crop-culture. Carrying on intensive crop-culture, increasing productivity and utilization ratio of land, squeezing some field land out for developing various cultures will be possible.

运用农业系统工程的观点,采用指数模型方法,本文对广汉县1978—1983年的种植业和农业生产发展动态进行了系统分析和系统综合。结果是:促使广汉县种植业产值指数持续增长的主导因素是农作物,特别是粮食作物单位面积产量的迅速提高。油菜生产是广汉县的一大优势,种植业产值增长似与油菜面积的扩大有相关性。适当地扩大油菜面积和调减小麦面积是协调粮经作物关系的可行途径。农业结构的调整可以从种植业上见效。实行集约化种植,提高土地的生产率和利用率,提高各种作物单产,挤出部分耕地发展多种经营是可能的。

According to the principles of ecolomics, taking Guyuan Ranch of Hebei province as a study site, the method for realizing profitable ecolomic recycling of the Bashang region has been investigated through modeling of systems engineering. The system dynamic model was applied as the main model which expres -sed the general feedback relations of the whole system structure. Monte Carlo method was used to simulate the impact of erosion on soil fertility. A comprehensive integration of qualitative and quantitative analysis, coefficient simulation, and grey system model was used for prediction. An "Ecolomic Laboratory" has been established to reflect the trand of ecolomic development of that region and its regularity of variation. Several programs have been formulated based on the practical experiences and qualitative analysis. A comprehensive evalution was carried out according to the results of computer emulation to seek for strategy and measures of continual development and mutual promotion of agriculture and animal production consistent with natural environmental conditions.

本文依据生态经济学原理,以河北省沽源牧场为例,用系统工程的模型方法探讨实现坝上生态经济系统良性循环的途径。作者采用系统动态模型作为主干模型,表现整个系统的结构和主要反馈关系,用蒙特卡罗法模拟风蚀对土地肥力的影响,综合运用定性定量技术、系数模拟、灰色系统模型等方法进行预测,借助电子计算机建立一个能够反映坝上生态经济系统发展势态和变化规律的“生态经济实验室”;并以实际工作经验和定性分析为基础,制订若干方案,根据计算机仿真结果进行综合评判,寻求农牧业生产与自然环境相互促进,持续发展的策略和措施。
