马尾松光合生理特性及资源利用效率研究进展

马尾松是我国南方生态恢复与重建的先锋树种，具有耐干旱、耐贫瘠及速生丰产等优点，其人工林在我国森林资源总量中占举足轻重的位置，但纯林的养分循环差，易导致生产力低下；而研究马尾松光合生理特性及资源利用效率可以为马尾松人工林生产力的提高提供坚实的理论基础。文中综述马尾松光合生理特性及资源利用效率的研究进展，分析逆境胁迫对其光合生理特性及资源利用效率的影响，包括水分胁迫、热胁迫、酸雨胁迫、低磷胁迫及铝胁迫等。在全球变化背景下，研究马尾松光合生理特性与资源利用效率及其对逆境胁迫的响应，对于制定马尾松的管理与保护策略、挖掘其抗性潜力具有重要意义，可为马尾松林分生产力的提升及纯林改良策略的制定提供理论参考。

A Review on Photosynthetic and Physiological Characteristics and Resource Use Efficiency of Pinus massoniana

Pinus massoniana is a pioneer species applied in ecological restoration and reconstruction in southern China, which has some advantages of strong tolerance to drought and barren, fast growth and high yield. Therefore, P. massoniana plantation occupies an important part in the forest resources in China. However, the poor nutrient cycling of pure P. massoniana forest results in its low productivity. Accordingly, the study of P. massoniana photosynthetic and physiological characteristics and its resource use efficiency could provide solid theoretical basis for increasing plantation productivity. This paper reviewed the research progress in P. massoniana photosynthetic characteristics and its resource use efficiency. We further analyzed the effects of adversity stress, such as water stress, heat stress, acid rain stress, phosphorus deficiency and aluminum stress, on its photosynthetic and physiological characteristics and resource use efficiency. Under the context of global climate change, the studies of P. massoniana photosynthetic and physiological characteristics, resource use efficiency and their responses to adversity stress, could contribute to developing strategies to manage and protect P. massoniana and extract its potential resistance. Consequently, it can provide scientific theories for increasing the productivity of P. massoniana plantation and preparing improvement strategy for pure forest.
