摘要
分析我国黄土高原地区坡耕地引起水土流失、肥力低下、水源缺乏、灾害频繁的四大问题 .根据黄土高原生态环境脆弱的具体情况 ,提出以下对策 :①提高对退耕还林 (草 )的认识 ;②解决好退耕后的脱贫致富问题 ;③促进东西部合作 ;④保证一定的基本农田 ;⑤实现农林牧业的最佳结合 ;⑥提出合理的退耕措施 ;⑦建立完善的保障机制 ;⑧正确处理各种关系 .
Analysed are four problems existing in sloping fields of the Loess Plateau:soil and water losses,low soil fertility,insufficient water resources,and frequent calamity.Some suggestions are put forward concerning returning farmland to forests and grassland,according to the specific conditions of fragile ecological environment of the Loess Plateau,and some measures are proposed.
