新疆阿尔泰区域矿产特征与古老基底的关系探讨

新疆阿尔泰地区矿产存在着明显的东西差异，究共原因是阿尔泰处于三大板块的会聚部位．不同的基底性质有所不同。该地区前寒武系基底主要由元古代克木齐群和富蕴群岩石组成，克木齐群属中下元古代，主要分布于阿尔泰西部和南部．富蕴群属中上元古代．主要分布于阿尔泰东部、东北部。岩石学和岩石化学特征表明，克木齐群更多具有上地幔和下地壳的成分．富蕴群则具有上地壳的成分；稀土元素分配特征和铅同位素特征表明东西部矿床和各自的基底关系密切，后者的差异导致了新疆阿尔泰地区矿产特征的差异。

Total nitrogen and community turnover determine phosphorus use efficiency of phytoplankton along nutrient gradients in plateau lakes

Numerous studies support that biodiversity predict most to ecosystem functioning, but whether other factors display a more significant direct impact on ecosystem functioning than biodiversity remains to be studied. We investigated 398 samples of the phytoplankton phosphorus resource use efficiency (RUE_P = chlorophyll-a concentration/dissolved phosphate) across two seasons in nine plateau lakes in Yunnan Province, China. We identified the main contributors to phytoplankton RUE_P and analyzed their potential influences on RUE_P at different lake trophic states. The results showed that total nitrogen (TN) contributed the most to RUE_P among the nine lakes, whereas community turnover (measured as community dissimilarity) explained the most to RUE_P variation across the two seasons. Moreover, TN also influenced RUE_P by affecting biodiversity. Species richness (SR), functional attribute diversity (FAD2), and dendrogram-based functional diversity (FDc) were positively correlated with RUE_P in both seasons, while evenness was negatively correlated with RUE_P at the end of the rainy season. We also found that the effects of biodiversity and turnover on RUE_P depended on the lake trophic states. SR and FAD2 were positively correlated with RUE_P in all three trophic states. Evenness showed a negative correlation with RUE_P at the eutrophic and oligotrophic levels, but a positive correlation at the mesotrophic level. Turnover had a negative influence on RUE_P at the eutrophic level, but a positive influence at the mesotrophic and oligotrophic levels. Overall, our results suggested that multiple factors and nutrient states need to be considered when the ecosystem functioning predictors and the biodiversity-ecosystem functioning relationships are investigated.
