| 【目的】为探讨不同覆盖作物模式对茶园节肢动物群落多样性与稳定性的影响。【方法】选择湖北省十堰市郧阳区谭家湾镇圩坪寺村茶园为研究对象,以两种(EZ)、四种(SZ)、八种(BZ)不同覆盖作物为处理,自然留养杂草为对照(CK)。统计和分析节肢动物群落组成、多样性指数(Richness index)、均匀度指数(Shannon index)和优势度指数(McIntosh index)的时序变化。【结果】结果表明：不同覆盖作物模式对茶园节肢动物群落结构特征不同,各处理节肢动物群落的科数无明显差别；而个体数以SZ>BZ>EZ>CK顺序依次减少；随着时间变化,节肢动物多样性指数呈先上升后下降再上升再下降的趋势,丰富度指数呈先缓慢上升后下降的趋势,均匀度指数呈先缓慢上升后缓慢下降再缓慢上升再缓慢下降的趋势；覆盖作物能有效提高茶园节肢动物数量,尤其以四种不同覆盖作物效果最为明显。【总结】综合分析茶园节肢动物群落多样性和稳定性,初步认为四种不同覆盖作物模式是目前茶园较适宜的覆盖模式。 |

| [Objective] To investigate the effects of different cropping patterns on the diversity and stability of arthropod community in tea gardens. [Methods] The tea garden of Lupingsi Village, Tanjiawan Town, Yuyang District, Shiyan City, Hubei Province was selected as the research object. Two kinds of (EZ), four (SZ) and eight (BZ) different crops were treated as natural vegetation. Weeds are control (CK). Statistical analysis and analysis of seasonal changes in arthropod community composition, Richness index, Shannon index, and McIntosh index. [Results] The results showed that the structure of arthropod community in tea garden was different under different coverage crop patterns, and there was no significant difference in the number of arthropod community in each treatment; the number of individuals decreased in SZ>BZ>EZ>CK order; The arthropod diversity index increased first, then decreased, then increased and then decreased. The richness index increased slowly and then decreased. The uniformity index increased slowly, then slowly decreased, then slowly rose and then slowly decreased. Crops can effectively increase the number of arthropods in tea gardens, especially with four different crops. [Summary] A comprehensive analysis of the diversity and stability of arthropod community in tea gardens is preliminarily considered to be a suitable coverage model for tea gardens. |
