摘要

以纸坊沟流域1938—2008年调查数据为基础，对其农业生态经济系统各阶段的农用地功能进行判定，并采用单一动态度指数和土地利用综合指数分析了其动态变化过程。结果表明，随着农业生态经济系统的演变，该流域农用地功能经历着"生存、生态功能→收入、就业功能→生态、收入功能"的演变过程；流域农用地的利用方式也经历了林地向耕地流转→耕地向园地和林地流转的过程；引起这一演变过程的驱动要素主要是流域人口、农民需求、农业效益以及国家政策的宏观调控。

Abstract

The determination of agriculture land function and its dynamic variation in Zhifanggou watershed of loess hilly region were conducted with single change rate and dynamic land use comprehensive index method based on field investigated data(1938)2008).Results showed that the agriculture land functions evolved the following process: survival and ecological income and employment ecological and income during the evoluation of agriculture eco-economic system.The agriculture land use also experienced two stages:forest land converting to farmland farmland converting to garden land and forest land.The evolution trend was driven by the interact ion of populations

farmer requirements

agriculture benefit and government macro policies.
