Discussion on Agricultural Technique of Sustainable Development in M ountain Area──Agricultural duplicitous ecological technique in mountain area

山地农业复式生态技术是在山区水土整治和农业综合技术基础上发展起来的新型土地开发利用技术，是实现山区土地永续利用和农业经济持续增长的重要途径。包括山地复式梯田、果园、草场、防护林四个子系统。其根木特点是最大限度减少工程投入，增加土地利用层次立体经营，全面提高多年生植物覆盖率，以获得更好的生态、经济和社会效益。

Agricultural duplicitous ecological technique in mountain area，a new technique of landdevelopment and utilization，is an important way for realizing sustainable utilization of land inmountain area and sustainable increase of agricultural economy on soil and water managment inthis area and agricultural overall technique basis，which covers four subsystems of duplicitous ter－race in mountain area，orchard，range and protection forest．Its features is to minimize input ofengineering，increase solid management of land utilization hierarchy and overall improve perennialvegitation covcragc so as to gain well—to—do ecological．economic and social benefits。
