| 摘 要： | 三峡库区是我国生态环境最为敏感和脆弱的地区之一.近年来,库区农业面源污染日趋严重,已引起国内外的广泛关注.传统农业耕作模式是产生农业面源污染的重要原因,因此选择正确农田耕作方式,防止水土流失,控制农业面源污染一直是探索的重大课题.为此,结合国内外保护性耕作技术已有的研究成果,针对库区地形、气候和种植作物等条件,以及库区保持水土、控制农业面源污染物、农作物稳产高产、农民增产增收等目标,选择了秸秆留茬覆盖、少耕免耕、等高耕作和梯田建设等保护性耕作技术,最后提出了相关建议.

| Abstract: | The Three-Gorge Reservoir area is one of the areas with the most sensitive and the most fragile eco-environment area in China.In recent years,agricultural non-point source pollution(ANPSP) in the Reservoir areas is becoming more and more serious,and has received tremendous attention at home and abroad.ANPSP in the Reservoir areas is driven by many factors,such as special environment conditions and emigration stress,but irrational tillage way is also important reason.So the correct choice of tillage way to p... |
