| 摘 要： | 元谋干热河谷气候干旱炎热,生态环境脆弱,水土流失严重,长达7个月的旱(干)季和缺乏灌溉条件使得大面积旱坡地生产力极低,成为本区农业发展的最大制约因素。按照农业生态学理论,科学发展草地农业,以圈养牲畜取代传统放牧,改变旱坡地利用方式,是提高人民群众生活水平,改善生态环境,治理水土流失的有效途径和重要战略举措。

| Abstract: | Yuanmou dry-hot valley characterizes in drought and hot in climate,therefore the ecological system was fragile and soil erosion was serious in this area.The dry season may last for seven months and lack of irrigation result in low productivity of large areas of slope land.These factors highly inhibits agricultural development in this area.Based on agroecological theory to develop grassland agriculture,rear livestock in pens should be used to replace the traditional livestock.Alteration of utility pattern of the dry slope land is an effective way to improve local people＇s living level,ecological environment,as well as to mitigate water and soil erosion. |
