摘要
本文探讨了山地子系统,绿洲子系统和荒漠子系统所组成的链状耦合系统─—荒漠─球洲草地农业系统的耦合效益与它的模型。提出了与之相应的线性规划与系统动力学模型,优化后的结果表明,在保持生态系统正常运转,永续利用的条件下,系统耦合后的社会总体效益可提高3.7倍,畜牧经济效益提高15.72倍。
In this paper
discussed the coupling effect between the subsystems of agricuItural pred uction in theareas of
mountains,oases and deserts within the general agro-grassland system in the Hexi
Corridor,GansuProvince. The chain-like coulping relationshipe between the subsystems were
described and optimised by alinear programming and the dynamic models,The results of
modeling indicate that the optimal couplingmeasures would increase economic returns to a
level of 3.7 times as much as the present one for the wholesystem and 15.72 times for
livestock preduction only,without disturbing the normal functions andsustainability of the local
ecosystem.
