中文摘要	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/（hm~2·a）,经济产投比242.8%,土地生产率9 469.8元/（hm~2·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。
英文摘要	From 2005 to 2007,study on composite shrub-grass modes of establishment on the degraded mountain in Yongsheng county in Yunnan province in the Jinsha River hot-arid valley.The results showed that the net profit,economic production-invest ratio and land production relation is shrub+grass+vine>shrub+shrub >shrub>grass+vine>grass+grass>grass>degraded mountain in planting models.The best planting model is Cajanus cajan + Setaria sphacelata + Festuca arundinacea+ Macroptilium atropurpureum+ Trifolium repens+ Trifolium hybridum.Its net profit,economic production-invest ratio and land production relation are 5 749.8 yuan/(hm~2·a),242.8% and 9 469.8 yuan/(hm~2·a) respectively.It can improve the physical characteristics of soil,increase soil porosity and infiltration rate of soil,balance the rate capillary porosity and non-capillary porosity,reduce the soil bulk density,lessen soil erosion and control water and soil loss,change soil water utilized,increase soil stability.Therefore,the planting model of Cajanus cajan + Setaria sphacelata + Festuca arundinacea+ Macroptilium atropurpureum+ Trifolium repens+ Trifolium hybridum has great significance in ecological and economic benefits.It is science model of ecological restoration and reconstruction on the degraded mountain in the Jinsha River hot-arid valley.
