摘要:

为探究伊犁河流域荒漠草原不同植物功能群下蝗虫的群落结构特征及其影响因子,采用路线调查和典型样地布设相结合的方法确定蝗虫的发生情况,运用数量生态学的统计方法揭示荒漠草原蝗虫群落结构的主要影响因素。结果表明,伊犁河流域荒漠草原蝗虫物种数为4科、12属、20种,优势蝗虫主要为意大利蝗(Calliptamus italicus)、黑腿星翅蝗(Calliptamus barbarus)、小米纹蝗(Notostaurus albicornis)、黑条小车蝗(Oedaleus decorus decorus)和蓝胫戟纹蝗(Dociostaurus tartarus)。不同植物功能群间蝗虫的Shannon-Wiener指数无显著差异,但禾本科植物功能群样地蝗虫的S?rensen指数较菊科植物功能群样地显著提高61.00%(P<0.05),其他植物功能群间无显著差异。置换多元方差分析进一步表明,蝗虫密度在不同植物功能群间也存在显著差异(F=4.37,P<0.05)。通过构建结构方程模型和随机森林模型表明,年均温、日照时长、植被盖度是驱动伊犁河流域荒漠草原不同植物功能群下蝗虫群落密度的主要影响因子。以上研究结果为伊犁河流域荒漠草原蝗虫可持续治理提供理论依据。

Abstract:

In order to explore the characteristics of the grasshoppers community structure and its influencing factors in Yili River Basin desert grasslands, the combination of route surveys and typical sample plots were used to determine the occurrence of grasshoppers, and revealed the main influencing factors of the grasshopper community structure in desert grasslands by using statistical methods of quantitative ecology. The results showed that the number of desert grasshopper species in the Yili River Basin desert grasslands was 20 species, which belonged to 12 genera and 4 families. The dominant grasshoppers were Calliptamus italicus, Calliptamus barbarus, Notostaurus albicornis Oedaleus decorus decorus and Dociostaurus tartarus. There was no significant difference in Shannon-Wiener index of grasshopper alpha diversity among different plant functional groups. The S?rensen index of grasshoppers in the Gramineae functional group were significantly higher than that in the Asteraceae functional group by 61.00% (P<0.05), and there were no significant differences between other plant functional groups. The results of permutational multi-variance analysis further showed that there were significant differences in grasshopper density among different plant functional groups (F=4.37, P<0.05). The structural equation model and random forest model showed that average annual temperature, sunshine duration and vegetation coverage were the main influencing factors that drived the density of grasshopper communities under different plant functional groups in the desert grasslands of Ili River Basin. Above results provided a theoretical basis for sustainable management of grasshoppers in desert grasslands of Ili River Basin.
