摘要

[目的] 分析党河流域骆驼刺群落特征与土壤因子相关性

为有效管理该流域天然骆驼刺群落及退化骆驼刺群落的恢复提供科学依据。[方法] 利用"样方"法

于2012年6-10月调查群落特征及土壤样品数据

进行回归分析。[结果] 在6-10月

生物量表现出显著的季节变化

Simpson优势度指数和Pielou均匀度指数季节变化趋势几乎一致

Shannon-Wiener多样性指数变化趋势相反。在0-50 cm土壤层内

随土壤深度的增加

土壤电导率、土壤pH值呈现出先增加再减小的变化过程

土壤容重表现出逐渐增大的趋势

土壤含水量在土壤深度达到30 cm以后增加不明显。[结论] 土壤环境因子是影响骆驼刺群落特征、生物多样性和生物量的主要因素。较高的土壤含水量可以增加骆驼刺群落的生物多样性

较高的土壤容重抑制骆驼刺群落根系的生长。

Abstract

[Objective] The correlations between characteristics of Alhagi community and soil factors in Danghe River basin were analyzed in order to provide a scientific basis for the effective management of natural Alhagi community and the restoration of degraded Alhagi community in this basin.[Methods] By means of quadrat method

the data of community characteristics and soil samples were surveyed and collected from June to October in 2012. Regression analysis was carried out.[Results] From June to October

the biomass exhibited significant seasonal variation

and the seasonal variations of Simpson's dominance index and Pielou's evenness index were almost accordant

while the Shannon-Wiener diversity index varied differently. In layers of 0-50 cm

with the increase of soil depth

soil electrical conductivity and pH value both increased firstly and then decreased; while soil bulk density increased gradually. In addition

soil water content was observed no increase at 30 cm or deeper layers.[Conclusion] Soil environmental factors showed the major influence upon the characteristics

biodiversity and biomass of Alhagi community. High soil water content could increase the biodiversity of Alhagi community

and high soil bulk density might inhibit the root proliferation of Alhagi.
