摘要
在探讨黄土丘陵区生态环境恶化根源及农业发展定位问题的基础上 ,概括了生态退耕的实质及不同退耕模式的特点。通过对“梯田退耕”与“赈济退耕”、“坝系根治”在退耕规模、投资需求、效益及粮食安全性等方面的对比分析 ,结论认为黄土丘陵区的生态环境建设应及早步入“梯田退耕”的路子。
Based on discussing the causation of eco-environment deterioration and the orientation of agricultural development in the loess hilly-gully region,the author analyzed the essential of de-farming slope farmland,summarized the characteristics of“rebuilding terrace and de-farming”,“relieving and de-farming”and“dam system and permanent control”,compared and contrasted the three patterns in de-farming area,investment demand,benefits and food security.The result showed that eco-environment restoration of the loess hilly-gully region should follow the route of rebuilding terrace and de-farming slope farmland as soon as possible.
