受全球气候变化和人类活动的影响,干旱环境缺水现状正越来越严重,干旱区正在扩散.如何抑制这种蔓延趋势,逐步改善干旱区环境是当前亟待解决的全球性难题.基于多年来对干旱务件下植物物候节律、形态生长特性和资源利用策略等植物生长适应机制以及植被调控的研究结论,提出在今后的理论研究或植被实践中加强干旱条件下植物物候特征及其生理机制、全球气候变化下干旱环境植物的生长适应策略响应和以生长适应机制为基础的干旱环境植被调控实践等方面的研究,以通过深入了解干旱条件下植物的生长适应策略及其机制,指导干旱地区的植被实践,遏止干旱环境不断恶化的趋势.
Progress of Plant Adaptive Strategies to the Drought Environment
With the effects of global climate change and human activity ,water deficit are more and more serious in drought systems, which are extending the drought area and aggravating the execrable drought environment step by step. The current crucial problem is how to inhibit the extending tendency, and improve the drought environment. Therefore, the practice of vegetation modification and the adaptive strategies as plant phenological rhythm,morphological and growth characteristics,and resources use polices in the drought system were reviewed. Based on these previous results,future research include plant phonological rhythm and its physiological explanation,the responses of plant adaptation to global climate change, the practice of vegetation modification in drought system supported by plant growth adaptation should be strengthened to enhance vegetation coverage, stable the drought system, further stop the expanding of drought area.
