摘要/Abstract

摘要：

植物物候是生态系统对气候变化响应的重要指示器, 是植物生产力与植被动态模拟的重要参数。但是植物物候对全球变化的响应是否存在年际间变异、年内变异、物种间变异或生境间变异, 以及如何改变, 目前仍然不明确。该研究基于内蒙古荒漠草原长期增温和氮添加实验平台, 选择优势植物短花针茅(Stipa breviflora)、冷蒿(Artemisia frigida)和木地肤(Kochia prostrata)为研究对象, 使用物候打分观测方法和Richards生长曲线拟合方法, 研究了实验处理第11、12和13年(2016-2018年)期间增温和氮添加对植物物候的影响。研究结果表明: (1)短花针茅开花时间集中在第129-145天, 冷蒿开花时间集中在第230-248天, 木地肤开花时间集中在第194-222天。增温、氮添加和增温+氮添加均使短花针茅和木地肤开花时间趋于提前, 冷蒿开花时间趋于推迟。(2)短花针茅结果时间集中在第134-148天, 冷蒿结果时间集中在第241-260天, 木地肤结果时间集中在第207-231天。增温、氮添加和增温+氮添加处理均使短花针茅和木地肤结果时间趋于提前, 冷蒿结果时间趋于推迟。(3)短花针茅生殖生长持续12-25天, 冷蒿生殖生长持续48-55天, 木地肤生殖生长持续45-77天。增温、增温+氮添加缩短了短花针茅而延长了冷蒿和木地肤的生殖生长时间。

Abstract:

Aims Plant phenology is an important indicator of ecosystem response to climate change, and it is also a central parameter for modelling plant productivity and vegetation dynamics. However, it remains unclear whether inner-annual, intra-annual, inter-species or inter-habitat variabilities exist in the response of plant phenology to environmental changes.
Methods Here we investigated the effects of long-term (>10 years) warming and nitrogen (N) addition on plant phenology in a temperate desert steppe. We used the phenological scoring observation method and Richards growth curve fitting method to monitor phenological shifts of three dominant species, Stipa breviflora, Artemisia frigida and Kochia prostrata, in the 11th, 12th and 13th treatment year.
Important findings We found that the flowering time ranged from the 129th to the 145th days of a year for S. breviflora, from the 230th to the 248th days for A. frigida, and from the 194th to the 222th days for K. prostrata. Warming and N addition tended to advance the flowering time of S. breviflora and K. prostrata, but tended to delay the flowering time of A. frigida. The fruiting time ranged from the 134th to the 148th days for S. breviflora, from the 241th to the 260th days for A. frigida, and from the 207th to the 231th days for K. prostrata. Warming and N addition tended to advance the fruiting time of S. breviflora and K. prostrata, but tended to delay that of A. frigida. The reproductive growth period lasted for 12 to 25 days for S. breviflora, 48 to 55 days for A. frigida, and 45 to 77 days for K. prostrata. Warming and N addition shortened the reproductive growth period for S. breviflora, but prolonged that period for A. frigida and K. prostrata.
