不同植被恢复方式对盐湖周边地区物种多样性影响的研究

吉兰泰盐湖位于内蒙古自治区阿拉善左旗。通过样方法调查了5种植被恢复方式下各实验地的物种多样性、丰富度指数、均匀度指数。研究结果表明：（1）Simpson多样性指数：保护造林区〉标准造林区〉对照区〉封育区〉封育灌溉区;Shannon-Wiener多样性指数：保护造林区〉标准造林区〉封育区〉对照区〉封育灌溉区;（2）Gleason和Margalef丰富度指数：保护造林区〉封育区〉标准造林区〉对照区〉封育灌溉区;（3）Pielou（E）和Pielou（Jsi）均匀度指数：封育灌溉区〉对照区〉标准造林区〉封育区〉保护造林区。

The Study on Effects of Species Diversity of Salt Lake Surrounding Area Under Different Vegetation Restoration Way

The Jilantai Salt Lake is located in Inner Mongolia,ALaShan ZuoQi.Though quadrat sampling method surveyed the diversity index、richness index、evenness index under 5 kinds of vegetation recovery in experimentation area.The results show that：（1） The Simpson diversity index： Protected afforest areaLevel afforestation area ComparisonLand enclosure areaLand enclosure＋irrigation area;Shannon-Wiener diversity index： Protected afforest areaLevel afforestation area Land enclosure areaComparisonLand enclosure＋irrigation area;（2）Gleason richness index and Margalef richness index： Protected afforest area Land enclosure area Level afforestation area ComparisonLand enclosure＋irrigation area;（3） Pielou Evenness index and Jsi Evenness index： Land enclosure＋irrigation area Comparison Level afforestation areaLand enclosure area Protected afforest area.
