- 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.
