| 摘 要： | 利用裂区试验设计对迪庆州金沙江干热河谷区5种不同坡度（8～15°，15～20°，20～25°，25～33°，≥33°）、9种不同植被（黑麦草、三叶草、大豆、腋花苋、苕子、仙人掌、黑沙蒿、大枣树、花椒树）条件下的土壤流失量进行了田间定量测定，综合评价不同植物在不同坡度的固土能力。结果表明:不同植被处理均能显著减少水土流失，其固土能力与坡度和植被品种有关。总的看来，9种植物的固土能力以草本植物腋花苋和三叶草最强，其它依次为麦草、苕子、黑沙蒿。仙人掌在25～33°陡坡上水土保持能力较强。

| Abstract: | The split plot experiment with 5 different slopes （8～15°，15～20°，20～25°，25～33°，≥33°）and 9 different plants cover（Amaranthus roxburghianus，Trifolium repnes.L，Lolium perenne，Vicia villosa，Artemisia ordosia，Opunntia dillenii，Glycine max，Ziziphus jujuba，Zanthoxylum bungeanum）was carried out to study the soil erosion in Diqing dry and hot valley of Jinsha river. The soil fixing capability of 9 different plants at different slope was studied. The results showed that, all of different plants cover treatments decreased soil and water loss remarkable. The soil fixing capability was closely related to the slope and the plant cover. On general, soil fixing capability of A. roxburghianusand clover (T. repnesL.) were the best, the secondly was ryegrass (L. perenne), V. villosa and A. ordosia, O. dillenii showed better soil stabilization at 25～33° slops. |
