- 摘要:
- 以内蒙古镶黄旗的封沙育林工程为研究区域，以2000年7月和2007年8月的TM影像为数据源，结合地面调查数据，从植被、土壤和风沙活动3个方面12项指标对镶黄旗北部沙化草原封禁治理效果进行了分析。结果表明：工程区的植被盖度、地上生物量和草层高度分别比自由放牧地提高了253.4%，112.4%，37.2%，植物种数增加，一年生植物比例降低。与工程实施前相比，固定沙地比例增加了124.1%，流动沙地比例减少了80.9%；土壤理化性质也得到了改良，如土壤有机质含量增加了36.2%、细沙比重增加了34.4%，并出现土壤结皮。
- Abstract:
- Selecting the enclosure project in Xianghuang banner as study area, taking the TM remote sensing image in July,2000 and August, 2007 as the data resource, combining with the ground survey data, it is analyzed the control effect of enclosing desertified grassland from 3 aspects (12 index). The results are as follows: vegetation coverage, biomass and height inside the project respectively increased by 253.4%,112.4%,37.2%; The amount of plant increased, the proportion of annual plant reduced. Compared with 2000, the proportion of fixed-sand is increased by 124.1%,while the proportion of flowing-sand reduced by 80.9%; In addition, the physical and chemical characters of soil were improved, for example: the soil organic matter content and silver sand proportion increased by 36.2% and 34.4% respectively and soil crust appeared.
