摘要:

为了研究河北省主要自然湿地2000年—2010年的变化情况及变化原因,运用ERDAS和ArcGIS对中国环境卫星2010年影像、2000年、2005年TM影像进行影像判读和数据处理,利用动态度指数和相关分析,对河北省主要自然湿地的动态变化和相关因子进行研究,探讨其动态变化状况和影响因子的影响程度。结果表明,河北省主要自然湿地面积减少严重,湿地自然保护区的建立是自然湿地保护的有效手段,人为因素的干扰成为自然湿地面积减少的主要原因。

Abstract:

In order to get the changes and the causes of main natural wetland in Hebei Province from 2000 to 2010, the image of China environment satellite in 2010, the TM image of 2000 and 2005 were used to analyze and research the changes which based on the technology of ERDAS and ArcGIS. The author also analyzed the data of dynamic degree to find the changes and the influencing factors for the dynamic variation of main natural wetland in Hebei Province. The study results showed that the area of natural wetland in Hebei Province were reduced seriously, and construct natural wetland reserves were the effective method to protect natural wetland, the reason which natural wetland generally reduced was the interference from human factors.
