| 中文摘要: |
| 对小坝子沙地植被恢复进程中植物与土壤相互作用过程进行观测分析,结果表明沙漠化地区在植被恢复初期植物多样性较低,土壤环境因子与物种多样性存在相关性,增加土壤的养分和水分有利于物种的繁衍。进一步利用多元统计方法对土壤因子进行了主成分分析,结果显示,土壤养分与水分表现出较大的因子累积贡献率,是该区域植被恢复的主导因子,土壤因子对物种多样性的变化有响应,土壤有机质与土壤水分等随物种多样性的增加将有所改善。 |
| 英文摘要: |
| The relationship of plantation diversity and soil factors in restoration process was researched.The results showed that plantation diversity was low in early succession stages of restoration process,and soil environmental factors related to species diversity.In order to accelerate the restoration of vegetation,the nutrients and water should be enriched in early succession process in sandlot.Using multivariate statistical analysis techniques(Principle Component Analysis),we found that soil nutrient and soil water had great cumulative effect.So soil factors influenced plantation diversity. |
