中文摘要	繁殖是植物生命活动的重要环节,了解植物的繁殖特征是解释植物生态适应性和制定有效管理措施的重要依据。该研究以荒漠草原猪毛蒿(Artemisia scoparia)种群为研究对象,通过测定不同土壤类型的理化性质和猪毛蒿的繁殖特征,以期探讨影响其繁殖特征的主要土壤驱动因子。结果表明:灰钙土、风沙土和基岩风化残积土的水溶性碳含量、全氮含量、全磷含量、全盐含量、土壤水分含量、土壤硬度存在显著差异。猪毛蒿平均个体大小、单株头状花序的平均质量和数量均以灰钙土生境下最大,基岩风化残积土最小。繁殖分配在不同土壤类型下无显著差异,但与单个头状花序质量、单株头状花序数量和质量间呈极显著正相关关系。单株头状花序数量与单个头状花序质量间呈负相关关系。在风沙土生境下,单株头状花序质量主要受到土壤水溶性碳含量、土壤水分含量以及pH值的共同影响;单株头状花序数量受全盐含量的影响最大;繁殖分配和单个头状花序质量主要受全碳含量的影响。灰钙土生境下,单株头状花序质量与土壤水溶性碳含量、土壤水分含量和有机碳含量呈正相关关系;速效氮含量显著影响着单株头状花序数量。而基岩风化残积土生境下,繁殖特征的变异主要受到土壤水溶性碳含量、土壤硬度、土壤水分含量、全磷和速效磷含量的影响。综合分析发现,土壤因子对猪毛蒿繁殖特征的影响程度不同,其中单株头状花序数量和质量极显著地受到土壤水溶性碳含量和土壤水分含量的影响,繁殖分配和单个头状花序质量与土壤水溶性碳含量、土壤水分含量呈负相关关系。因此,土壤水溶性碳含量和土壤水分是荒漠草原地区影响猪毛蒿种群繁殖特征的主要土壤因子。
英文摘要	Aims Reproduction is an important part of plant life activities, and thus the reproductive characteristics of plants play an important role in explaining the ecological adaptability of plants as well as developing effective management strategy plans. The aims of this study are to explore the reproductive characteristics of Artemisia scoparia and analyze its main soil driving factors in a desert steppe of China. Methods As a method to extract and summarize the variation in a set of response variables, the redundancy analysis can be explained by a group of explanatory variables. In the present study, we selected the A. scoparia population in a desert steppe, and examined physicochemical properties of different soil types and reproductive characteristics of A. scoparia with the redundancy analysis. Important findings There were significant differences in water-soluble carbon content (C_(ws)), total nitrogen content (TN), total phosphorus content (TP), total salt content (TS), soil moisture (M_s) and soil hardness (SH) of calcareous soil (SS), aeolian sand soil (ASS) and weathered residual soil (WB). The average mass (Ma), the number (N_i) of average individual head inflorescence, and the average individual size (S_(ai)) of a single plant were the largest in the SS habitat, followed by ASS and WB. No significant difference was observed in reproductive allocation (R_a) of A. scoparia in different soil types. An extremely significant positive correlation was observed between R_a and the quality of single capitate inflorescence (M_e), N_i and Ma, respectively, while N_i was negatively correlated with Me. The variation of the reproductive characteristics of A. scoparia was mainly affected by soil water soluble carbon content (C_(ws)), soil hardness (SH), soil moisture (M_s), TP and available phosphorus content (AP) in WB habitat. Ma was mainly affected by C_(ws), M_s and pH value; N_i was mainly affected by total salt content (TS); R_a and Me were mainly affected by total carbon content (Ct) in the ASS habitat. Ma was positively correlated with C_(ws), M_s and C_o, while the correlation between Ma and C_o was not significant; N_i was significantly affected by available nitrogen content (AN) in the SS habitat. A comprehensive analysis of the three soil types showed that the total explanatory amount of soil factors affecting the reproductive characteristics of A. scoparia was 30.74%. Ma and N_i were significantly affected by C_(ws) and M_s. R_a and Me were negatively correlated with C_(ws) and M_s though they are not statistically significant. We conclude that C_(ws) and M_s are the main soil factors affecting the reproductive characteristics of A. scoparia populations in the desert grassland.
