中文摘要：
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。
英文摘要：
In this paper,spot image data of 2006 were interpreted and corrected combining with field investigations.On this basis,the diversity of wetland landscape in Haba Lake Nature Reserve of Ningxia was studied.The results showed that the spatial variation of landscape diversity in Haba Lake Nature Reserve wetlands was obvious.Landscape diversity indices of Habahu wetland were the best,and that of Erdaohu wetland Luotuojing wetland were the worst.Reasons for space discrepancy of landscape diversity mainly were the impact of human activities the spatial difference of protection degree.
