摘要: 为研究典型立地条件下生态、经济、社会效益协调配合,综合效益最佳的退耕还林模式,推动退耕还林的可持续发展,该文以退耕还林重点工程区内蒙古自治区凉城县典型立地为研究对象,运用系统动力学等理论和方法,采取试验站点观测与入户调研集成等5个结合的技术路线,共获取原始数据10 000多个,对退耕还林的优化模式进行了系统研究.结果表明,凉城县试验点退耕还林优化模式为山杏×沙棘×紫花苜蓿,并研究提出了其系统仿真模型、模式配套技术及模式机理.

Abstract: In order to study the coordination of ecological,economic and social benefits to achieve an optimal model of conversion of farmland to forests(CFF),we investigated Liangcheng County,Inner Mongolia Autonomous Region,which is a typical site of CFF.Based on system dynamics(SD),this investigation adopted five technical methods combining observations at field stations and extensive investigations. Over(10 000) original data were obtained in the investigation.The results show that the optimal model in Liangcheng County is a mixed stand of Prunus armeniaca + Hippophae rhamnoides + Medicago sativa.The model contains specific supporting technologies and operational mechanisms.
