| 摘 要： | 对云南元谋干热河谷旱坡地水土流失和土壤退化严重的地区,引进豆科速生树种南洋樱,以30 cm×40 cm株行距、品字形双行等高栽植快速形成植物围篱。结果表明,南洋樱植物篱在元谋干热河谷旱坡地生长良好,并且在种植3年间,治理区径流发生次数明显减少,年径流模数减少了29.13×104m3/km2,减少率76.90%;土壤年退化减少12 986.8 t/km2,减少率76.02%。研究区降水量与径流量间者的相关系数由建植篱前的显著相关变为不显著;有机质和钾流失减少量高达3 111.64 kg/hm2和3276.57 kg/hm2。南洋樱植物篱在控制旱坡地水土流失、减少土壤侵蚀和改善土壤养分等效益显著。 |

| Abstract: | The benefits of soil and water conservation by planting fast-growing leguminous plant Gliricidia sepium were studied in the area under serious soil and water loss in the dry-hot valley of Yuanmou County.The results indicated that G.sepium had a good adaptability to arid hillside field in dry season.In 3 years of planting,the runoff in the major control regions was greatly decreased.The runoff modulus was decreased by 29.13×104 m3/km2（76.90%）;soil degradation was decreased by 12 986.8 t/km2.yr（76.02%）.The correlation coefficient among rainfall and runoff was obviously changed.The organic matter and potassium losses were decreased by 31 11.64 kg/hm2 and 3 276.57 kg/hm2. |
