Verification of Environmental Improvement in Duoluncounty through Analyzing Land Use/Cover Change Processes

Abstract:

In the study we mapped and analyzed the land use/cover changes Duolun county (one of typical farming-pastoral ecotone of northern China) in previous 20 years by interpreting the multi-temporal TM images received growing season of 1990, 2000 and 2009. The 6 broad types and 12 sub-types of land use/ cover were visually interpreted to get the area of each land use/cover. Our study indicates that the area of grassland displayed stable, but the area of densely and moderate vegetated grassland increased apparently. The forested area also increased 11.51km2 from 46.21km2 in 2009, 34.13km2 in 2000 to 34.70km2 in 1990. In contrast, the area of farmland reduced from 7.82km2 during the 1st (1990-2000) period, and 101.14km2 during the 2nd (2000-2009) period, and desert area declined to 149.07km2. On the whole, the ecosystem improvement is very significant.
