摘要
以蒙古兴安盥科石前旗大坝沟乡为例,应用目标规划方法,对农业生态系统综合发展进行了探讨。结果表明:不同发展阶段有不同的目标优先序以及相应的优化调控方案;最优方案的解集是不要求每个目标都同时达到最优值的一种符合决策心理要求的满意解;某些生态效益指标显示出不同程度的“滞后效应”。
Taking Dabagou in Keyon Banner in inner Monggol Autonmous Region
as a typical example of the semiarid agroecosystems,we probed into the
coordination betwecn ecological feature and economical one in agroecosystems
by using the method of goal programming.Results showed that:1) there
were diffient goal-optimal orders and relevant optimal schemes in diffient
stages:2) the solutions set up were only satisfied ones,not all of the goals
needed to be optimalvales with best comprehensive benifit;3) some criteria
of ecological benifits gave expression to delayed effect.
