摘要：

为探讨全球气候变化背景下多元线性混合模型（IsoSource）和贝叶斯混合模型（MixSIAR）解析宁夏河东沙地柠条锦鸡儿（Caragana korshinskii）水分利用策略差异及适用性,利用氢氧稳定同位素技术,结合直接对比法、IsoSource模型和MixSIAR模型对比分析不同坡度（6°、10°、16°和24°）样地柠条锦鸡儿在生长季不同时期对各潜在水源的利用率,并评估两种模型的植物水分溯源效果。结果表明：柠条锦鸡儿对不同土层深度土壤水的利用存在明显的季节性差异,生长季初期,随着坡度的增大,柠条锦鸡儿对中层土壤水的利用率呈现出先增大后减小的趋势;生长季中期,随坡度增大,柠条锦鸡儿主要水分来源由深层土壤转移至浅层土壤;生长季后期,柠条锦鸡儿主要水分来源随着坡度的增大由浅层土壤转移至深层土壤。基于直接对比法的定性判断结果,IsoSource模型和MixSIAR模型计算坡度6°、10°和16°样地柠条锦鸡儿主要水分来源利用率的适用性均较高;而MixSIAR模型计算坡度24°样地柠条锦鸡儿主要的水分来源以及其贡献率具有更高的可靠性。IsoSource模型更适合解析较小坡度（6°和16°）样地柠条锦鸡儿的水分利用策略;而MixSIAR模型解析较大坡度（10°和24°）样地柠条锦鸡儿水分利用策略的适用性更好。研究结果可为我国干旱区植物水分来源鉴别方法的选择提供科学参考。

Abstract:

We investigated the differences and applicability of IsoSource and MixSIAR models in resolving the water use strategies of Caragana korshinskii in the east sandy land of the Yellow River in Ningxia Hui Autonomous Region, China. Under the context of global climate change, we used IsoSource and MixSIAR models to analyze the use of each potential water source by Caragana korshinskii on different slopes (6°, 10°, 16°, and 24°) during different periods of the growing season. We then applied hydrogen-oxygen stable isotope technique and direct comparison method to evaluate the effectiveness of both models for plant water traceability. The results showed seasonal differences in the use of soil water by Caragana korshinskii at different soil depths. With the increasing slope, the use of soil water by Caragana korshinskii in the middle layer first increased and then decreased at the beginning of the growing season. In the middle of the growing season, the main source of water for Caragana korshinskii shifted from deep to shallow soils. Later in the growing season, the main source of water for Caragana korshinskii shifted from shallow to deep soils. On the basis of the qualitative results of the direct comparison method, both models were applicable for calculating the utilization rate of the main water source of Caragana korshinskii in the small sites on 6°, 10°, and 16° samples. The MixSIAR model was more reliable than the IsoSource model in calculating the main water source of Caragana korshinskii and its contribution rate on the large slope samples. Therefore, the IsoSource model was suitable for analyzing the water use strategies of Caragana korshinskii on small slope (6° and 16°) samples, whereas the MixSIAR model was suitable for analyzing the water use strategies of Caragana korshinskii on large slope (10° and 24°) samples. The results of this study provide a scientific reference for the selection of methods to identify plant water sources in arid zones in China.
