黄土丘陵沟壑区退耕驱动下土地利用变化——以陕西省安塞县纸坊沟流域为例
摘要：
随着国家大力推行退耕还林政策的深入实施，许多黄土丘陵沟壑区的农民纷纷参与其中。该政策在一定程度上实现了退耕还林的目标，也给安塞县纸坊沟流域的土地利用变化带来了深刻的影响。本文通过对安塞县纸坊沟流域进行调查和分析，探讨了黄土丘陵沟壑区退耕驱动下土地利用变化的原因、特点和影响。结果表明：退耕还林政策的推行，使得纸坊沟流域的宅基地面积减少，耕地面积和林地面积增加，荒地面积显著减少，土地利用的格局和结构发生了明显变化，推动了流域土地资源的可持续利用。但同时，该政策也带来了一系列问题，如农民收入减少、宅基地使用问题、土地承包问题和生态环境问题等。因此，在未来的退耕还林工作中，需要更加普及政策宣传，加强社会化的公益林体系建设，同时也要加大扶贫力度，保障农民的基本生活和资本积累。
