Climatic suitability and productivity zoning for sustainable utilization of Dendrocalamus latiflorus in China

Abstract

本研究整合了132条分布记录、95个野外调查样地、BIOMOD2集成物种分布模型框架以及基于迈阿密气候的生产力模型,评估了中国大花竹(Dendrocalamus latiflorus Munro)当前和未来的生境适宜性、气候约束下的生产力以及种植区划。在当前的验证框架下,集成模型表现出较高的区分能力(AUC = 0.979;TSS = 0.908)。变量重要性分析和响应曲线表明,BIO9和BIO2是主要的气候预测因子,适宜性在BIO9阈值10.4 °C以上迅速增加,但在日温差过大时则下降。在当前气候条件下,高度适宜的区域集中在华南沿海、海南、台湾和云南东南部,这些区域的适宜性与高气候生产力(>2250 g C m⁻² yr⁻¹)广泛重叠。将适宜性与气候生产力相结合,确定了33.02 × 10⁴ km²的核心种植区,占适宜范围内气候生产力潜力的71.31%。未来预测表明,本世纪初至中期适宜生境将有所扩张,但随着本世纪后期气候变暖加剧,适宜生境将出现收缩和破碎化。基于田间生长分析的进一步结果表明,生物量对适宜性梯度的响应比茎秆高度或胸径更为强烈,并且当预测适宜性超过约0.5时,生长性能开始趋于一致。总体而言,本研究为将 D. latiflorus 的适宜性、气候限制生产力和生长响应联系起来提供了一个综合框架,与气候变化下的工业竹种植评估和区域规划直接相关,同时强调了在地方种植园尺度上谨慎解释的必要性。
