| 摘 要： | 以奈曼旗兴隆沼为研究对象,通过28年实地调查与观测,提出了半干旱退化沙地人工林复合生态经济系统恢复模式,并对该模式的生态效应进行了监测。结果表明:退化沙地人工林复合生态经济系统恢复模式建成后,该地区控制流沙面积达1 806.7 hm2,农作物的光合利用率由原来0.41%(1977年),提高到0.77%(1989年),农田土壤风蚀模数减小了6.09倍,土壤养分损失量减少了74%,防风固沙效益提高了83.57%。 |

| Abstract: | Taking Xinglongzhao in Naiman County as the research object,on the base of 28-year field surveys and observations,the compound eco-economic system restoration pattern of plantation is put forward in degraded sandy land in semi-arid area,and the ecological effect of this pattern is monitored.The results show that after building the compound eco-economic system restoration pattern of plantation in degraded sandy land,the area of the controlled quicksand has reached 1 806.7 hm2,the utilizing rate of photosynthesis of the crop has risen from 0.41%(1997) to 0.77%(1989),the soil wind erosion modulus of farmland has decreased by 6.09 times,the loss quantity of soil nutrient has decreased by 74%,the wind-breaking and sand-fixing effect has increased by 83.57%. |
| Keywords: | degraded sandy land plantation compound eco-economic system ecological restoration pattern |
