摘要: 通过对浑善达克沙地内典型区域进行遥感监测,利用Arcgis9.3软件对2003年和2012年的SPOT5遥感影像数据进行解译, 采用定量与定性分析相结合的技术手段, 分析土地利用地类、植被盖度、沙化类型及程度等内容。监测结果表明,典型区域经过十年的生态治理植被盖度增加了7.3%,区域森林覆盖率增加了6.9%。生态防护体系初步形成,区域生态环境得到明显改善。但局部地区仍存在超载放牧、开荒种地等现象。因此区域生态状况呈现“整体遏制、区域好转、局部恶化”的态势,区域生态建设正处在治理与破坏相持的关键阶段。

Abstract: Through the remote sensing monitoring of the representative region in Hunshandake Sandy Land, the authors interpreted the SPOT5 remote sensing image of 2003 and 2012 by ArcGIS 9.3, and the land-use type, vegetation coverage, desertification type and degree were analyzed by the quantitative method and qualitative method. The results showed that after 10 years ecological treatment, the vegetation coverage increased by 7.3% and the regional forest coverage increased by 6.9%. The ecological protection system was preliminarily formed and the ecological environment was improved significantly. But the phenomena of overgrazing and bringing wasteland into cultivation still existed in local region. The regional ecological condition presented a trend of integral-containment, regional improvement and local deterioration, the regional ecological construction was in the vital stage between governance and destruction.
