神东矿区不同治理分区相同治理年限典型灌木群落特征分析

为评估神东矿区典型灌木群落对矿区不同治理分区的适生性,探索其最佳配置模式,选取治理年限为10 a的沙棘群落、15 a的北沙柳群落和柠条锦鸡儿群落,对其群落基本特征进行了分析。从分析结果来看,沙棘群落在风积沙区长势最好,在硬梁地长势最差,不同治理分区适生性排序为风积沙区>黄土丘陵区>黄土丘陵和风沙交错区>硬梁地;北沙柳群落在黄土丘陵和风沙交错区长势最好,在硬梁地长势最差,不同治理分区适生性排序为黄土丘陵和风沙交错区>风积沙区>硬梁地;柠条锦鸡儿群落在黄土丘陵和风沙交错区长势最好,在硬梁地长势最差,不同治理分区适生性排序为黄土丘陵和风沙交错区>风积沙区>黄土丘陵区>硬梁地。在植物配置模式上,沙棘、北沙柳和柠条锦鸡儿在不同治理分区的配置选择顺序和其适生性保持一致。

The Characteristics of Typical Shrub Communities in Different Treatment Zones Division with the Same Treatment Years in Shendong Mining Area

In order to evaluate the adaptability of typical shrub communities in Shendong mining area to different treatment zones division and explore the best layout mode,the paper selected the Hippophae rhamnoides community with 10 years of treatment,15 years of Salix psammophila community and Caragana korshinskii community and analyzed their basic community characteristics. The outcomes show that a) the Hippophae rhamnoides community grows best in aeolian sand area and worst in hard ground land of ridge. The order of suitability of different treatment areas is aeolian sand area > loess hilly area > loess hilly and wind sand ecotone > hard ground land of ridge;b) Salix psammophila community grows best in loess hilly region and the wind sand ecotone and worst in hard ground land of ridge. The order of suitability of different treatment areas is loess hilly and aeolian sand crisscross area > aeolian sand area > hard ground land of ridge and;c) Caragana korshinskii community grows best in loess hilly and wind sand ecotone and worst in hard ground land of ridge. The order of suitability of different treatment areas is loess hilly and wind sand ecotone > aeolian sand area > loess hilly area > hard ground land of ridge. In the plant layout mode,the layout selection order of Hippophae rhamnoides,Salix psammophila and Caragana korshinskii in the different treatment zones should be consistent with its adaptability.
