| 摘 要： | 退耕还林还草中．建设生态系统与经济系统“弹性资源”,对于良性生态经济系统调控机制的形成具有重要的作用。通过对其概念的界定．得出了生态系统与经济系统“弹性资源”的3个重要特征：(1)具有多种可供利用的途径．可满足不同阶段生态环境建设和商品生产发展的需求;(2)具有稳定的生态经济系统结构和良好的自我调控机制;(3)满足生态目标、经济目标和社会目标的有机统一。以县南沟示范区为例研究了其弹性资源建设标准和进展。

| Abstract: | During land use conversion from cropland to forest land, establishing the flexible resource between ecological system and economic system is important in order to form an integrated eco-economic system. Having considered the possibilities, the authors propose three characteristics of an integrated system, namely: defined purposes and effects of establishing an ecological system and an economic system, a steady eco-(economic) system structure and favorable feedback relationships and interrelated ecological, economic and social targets. The authors also discussed standards for constructing and integrated system and analyzed the suitability of these for Xiannan Valley Demonstrating Area. |
