在2000年、2005年和2010年遥感数据支持下，通过对生态系统类型的辨识，获得大伙房水库饮用水源保护区生态系统类型数据，并从生态系统组成、变化及变化特征3个方面对其进行深入分析。结果表明：近10年来，大伙房水库饮用水保护区内森林和水体与湿地减少，人工生态系统增加，面积变化相对较小。自然生态系统的破坏在2000～2005年间比2005～2010年间严重，且集中在一级保护区外，以准保护区内居多。

With the support of Landsat TM data in 2000 and 2005 and HJ-1C data in 2010, by identification of ecosystem types, data concerning the ecosystem types in the drinking water protection zone of Dahuofang Reservoir is acquired. Composition, variation and variation characters of the ecosystem are further analyzed. The results show that in the recent ten years, forest, water and wetland in the drinking water protection zone of Dahuofang Reservoir have been reduced gradually, but the area of artificial ecosystem has increased. Therefore, the area variation is comparatively less. Damage of the natural ecosystem is more serious between 2000 and 2005 than that from 2005 to 2010, centered out of the key protection zone. That is, most of the natural ecosystem destroyed is located in the quasi-protection area.
