摘要
通过对固原上黄试验示范区农业生产中存在问题的调查分析,拟定了该区农业生态经济系统建设的总体构思、优化配置方案及实施技术。通过8年试验示范,研究了该区农业生态经济系统的结构功能特征及其变化,论述了该优化模型的可信度,进而对黄土丘陵西部地区农业生态经济系统建设提出了看法。
To analyse the existing problems on the agricultural production in Shang- huang Experiment and Exemplary Area,Guyuan county,the authors have draf- ted the overall conception,the optimum disposition programme and the imple- menting techniques for the construction of agriculture-ecology-economy sys- tem in this area.By experiment and exemplary,about eight years the au- thors analysed the characteristics of structure function and its changes for this system,and discussed the raliability of the optimum models and then put for- ward the suggestion for the construction of agriculture-ecology-economy sy- stem in the western loess Plateau.
