摘　　要：以退耕还林工程典型立地的干热干旱河谷区为研究区域 ,引入系统动力学等理论和方法 ,对退耕还林的优化模式进行了研究 ,提出了长江上游金沙江干热干旱河谷区云南省鹤庆县实验点退耕还林生态经济社会效益最优结合、可持续发展的圆柏×黑荆树 (Sabinachinensis×Acaciamearnsii)优化模式 ,并提出了相应的规范配套技术。The study covers the model area the dry hot and arid river valley subregion of the Conversion of Farmland to Forests Programme(CFF), and introduces system dynamics and other latest theories and methodologies. Based on the analytical work of five modules including that of the site observation of field stations and extensive investigations, and over 100,000 original data obtained in the fields of natural science, social science and economics, the optimized models were studied. Optimized operational models integrating maximized ecological, economic and social benefits while reflecting sustainability concepts were proposed for typical CFF sites: the Sabina chinensis × Acacia mearnsii model at the dry hot and arid river valley of Jinshajiang River of the upper Changjiang River. The model contains specific supporting technologies and operational mechanism.
