摘要

2005~2007年在金沙江干热河谷区的云南永胜县退化山地上建植了灌草复合型草地

分析结果表明

灌草复合型种植模式纯利润、经济产投比、土地生产率等的关系大小排序为:"灌草藤">"灌灌">"灌">"草藤">"草草">"草">"退化山地荒草坡"。其中"灌草藤"模式中的"木豆非洲狗尾草高羊茅大翼豆白三叶杂三叶"为最优模式

其纯利润为5 749.8元/(hm2.a)

经济产投比242.8%

土地生产率9 469.8元/(hm2.a)。该模式显著地改善了土壤物理性状

降低土壤容重

增加土壤孔隙度

有效地改变了毛管孔隙度与非毛管孔隙度比值

提高土壤保水能力

改变水分有效利用方式

提高土壤稳定性。因此

该模式是一种生态效益兼顾经济效益的生态治理模式

是金沙江干热河谷区退化山地恢复与重建的科学种植模式。
