Therefore, we selected common species of Ranunculaceae. comparative primordial plants in Alpine Meadow at Eastern QinghaiTibetan Plateau, and studied the reproductive strategies, such as reproductive allocation, especially sex allocation, to understand how the plants adapt the environmental conditions. The results showed:(1) At higher altitude, the self-incompatible plant, such as Trollius ranunculoides tended to become limited by pollination rather than by nutrient availability, while the self-compatible plants, such as Anemone rivularis and A. obtusiloba seemed not to be limited by pollen availability, which suggested that ability of self pollination for alpine plants may be a mechanism of reproductive assurance.(2) Influences induced by high altitude on the reproduction of these species occurred on different reproductive characters, which suggest species-specific adaptive strategies. The influences are dependent on plant size to some extent.

因此，我们选择在青藏高原东部的高寒草甸，以比较原始的植物类群—毛茛科植物为研究对象，选择一些常见种探讨其繁殖对策，如繁殖分配和性分配问题，试图揭示这些植物如何适应环境条件，最后的结果表明： 1高寒草甸高海拔区，自交植物(如小花草玉梅A.rivularis和钝裂银莲花A.obtusiloba)的繁殖不受花粉限制，而完全异交植物(毛茛状金莲花T.ranunculoides)的繁殖受花粉限制，表明高海拔地区植物的白花授粉能力可能是一种繁殖保障机制，能够避免恶劣环境对植物有性繁殖的不利影响； 2海拔高度对植物的影响因种而异，不同的物种受影响的繁殖性状不同，即使同属亲缘种间也存在差异，表明不同物种对相似环境压力的适应对策不同；而且，海拔高度对植物的影响在一定程度上依赖于植物个体大小，说明植物通过调整其个体大小与繁殖性状的关系来适应环境梯度的变化； 3植物花期和果期的繁殖分配并不完全随海拔升高而减小(只有小花草玉梅的果期RA随海拔升高而减小30％)，与Iwasa和Cohen的预测不完全一致(他们认为繁殖分配随生长季缩短而减小)。
