采用2006年spot影像数据,同时结合外业调查,对影像数据解译结果进行校核。在此基础上,对地处宁夏哈巴湖自然保护区的六大湿地景观多样性空间变化特征进行研究。结果表明:哈巴湖自然保护区湿地景观多样性空间变化明显,景观多样性各项指数均以哈巴湖湿地为最优,而二道湖、骆驼井等湿地景观多样性较差。导致景观多样性空间差异的主要原因一是人类活动的影响,二是保护力度的空间差异。
Using 2006 spot image data, combined with field surveys, video data interpretation results were checked. On this basis, the spatial variation characteristics of six wetland landscape diversity in Haba Lake Nature Reserve in Ningxia were studied. The results show that the diversity of wetland landscape in Habahu Lake Nature Reserve is obviously changed, and the index of landscape diversity is the best in Haba Lake wetland, while the diversity of wetland landscapes such as Erdao Lake and Camel Shale is poor. One of the main causes of the spatial difference of landscape diversity is the influence of human activities and the other is the spatial difference of protection efforts.
