| 摘 要： | 基于2001、2006年的TM/ETM遥感数据,利用像元二分模型,估算出不同时期内大山包黑颈鹤自然保护区的植被覆盖度,并对其变化进行了定量分析。结果表明,2006年较2001年的植被覆盖度呈增高趋势。植被覆盖度的变化与人类活动有密切关系,大山包黑颈鹤自然保护区核心区居民异地迁移工程以及国家级自然保护区的建立是大山包黑颈鹤自然保护区植被覆盖度增高的重要原因。

| Abstract: | Based on the TM/ETM images of 2001 and 2006,the vegetation coverage in different phases and areas of Dashanbao Grus nigricollis national nature reserve quantitatively estimated and analyzed with the revised dimidiate pixel model.The results show that the vegetation coverage in Dashanbao national nature reserve has presented an increasing trend from 2001 to 2006.On the whole,it was considered that there is an inseparable relationship between the vegetation coverage changes and human activities.The implementation of migration projects and construction of national nature reserve have achieved obvious active results. |
