【摘要】 该文综合样带法、样地法和样线法对哈巴湖自然保护区6大湿地进行全面的植被调查,并对外业调查数据进行统计分析。在保护区湿地植被优先保护等级评价模型构建的基础上,结合菲尔德法,对哈巴湖自然保护区6大主要湿地植被优先保护等级进行评价。评价结果表明:在哈巴湖湿地各项参评指标中,群落盖度、珍稀植物种等均较高,其综合评价结果最大(0.965),为一级保护湿地;骆驼井湿地和四儿滩湿地的评价结果为0.863和0.841,为二级保护湿地;柳杨堡湿地和二道湖湿地的评价结果为0.713和0.714,为三级保护湿地;评价结果最低的是高沙窝湿地(0.611),为四级保护湿地。更多还原

【Abstract】 Strip-transects,sampling plots and line-transects were used to survey the vegetation in six large wetlands in Haba Lake Nature Reserve of Ningxia,northwestern China.Based on the established evaluation model and the expert weighting method,the authors prioritized the vegetations in the six wetlands into four levels for protection purposes.The Haba Lake wetland,which had the highest score of 0.965,was classified as the first level protection wetlands.The Luotuojing and the Siertan wetlands had a score of 0.863 and 0.841,respectively,and were classified as the second level protection wetlands.The Liuyangpu and the Erdaohu wetlands had a score of 0.713 and 0.714 respectively,and were classified as the third level protection wetlands.The Gaoshawo Wetland had a score of 0.611,which was the lowest among all six wetlands,was classified as the fourth level protection wetland.更多还原
