生物在沙尘暴环境中的生命过程与适应机制是为当今生态学研究领域的主要科学问题之一；但沙尘暴对被子植物繁育系统的影响方面尚不清楚。因此，开展长期沙尘暴对不同花型近缘种繁殖对策影响的比较研究，对于揭示沙尘暴在不同植物类群繁殖对策及适应性进化的作用。黑果枸杞和清水河枸杞是新疆南部沙尘暴环境中生长的近缘种，在二者分布区内开花式样和种群更新能力间存在差异；推测沙尘暴是影响两者繁殖对策和适应机制间差异的主要因素。为了证实该假设，本项目将通过长期沙尘暴对黑果枸杞和清水河枸杞开花式样、花部综合征、传粉特性及交配系统开展比较研究，揭示这两物种在繁育系统特征上的异同点以及这些特点在二者沙尘暴环境适应过程中的作用，以期为全面揭示不同植物类群对长期沙尘暴适应的繁殖对策与机制方面提供重要的理论依据。

The sand and dust weather is one kind of disastrous weather, which can influence agricultural production and climate change. Although, effect of long term stand storm environment on plant reproductive strategies are still poorly understood. Therefore, the comparative study on influence of sand storm on two different floral morph sister species breeding system, can be plays an important role and provide theory material for investigation on breeding and evolution. Lycium ruthenicum and L.qingshuiheense is related species and sympatric distribution in sand storm environment in western Xinjiang, China. But there are great differences among them flowering patterns and species update ability in same population. We think that the sand storm is main factor of influence them breeding system and adaptation mechanism. To test this hypothesis, we will explore the effect of long term stand storm on flowering pattern, floral syndrome, pollination and mating system of two related species of Lycium in Xinjiang. At the completion of this study, we will ascertain the dynamic of breeding system and adaptation of two different floral morph related species in stand storm. Our overall goal is to develop a general theoretical basis for adaptation reproductive strategies of Lycium related species to long term stand storm environment.
