北京春季的树木物候与气象因子的统计学分析 总被引：23，自引：1，他引：22
本文采用积分回归法对北京春季的树木开花期与它前期气象因子的关系作了统计学分析,指出前期气温是影响这些物候期的主要因素,其次是日照时数和降水.上年秋至开花前的气温高低对开花期的早迟都有影响,但不同时期其影响效果不一样,可分成三个时期:在日照时数和降水保持一定的情况下,上年秋或当年春的气温偏高时,可使开花期提前,冬季气温偏高则使开花期推迟,反之亦然.而三个时期中,春季气温又有决定作用.本文还指出,可以利用该模式进行物候预报. 相似文献

贵阳木本植物始花期对温度变化的敏感度 总被引：1，自引：0，他引：1
植物物候期的温度敏感度反映了植物是怎样及在何种程度上响应气候变化,研究不同物种物候期的温度敏感度有利于鉴别易受气候变化影响的物种。现有关于始花期的温度敏感度研究主要集中在温带地区,在亚热带地区研究仍较少。本文以位于亚热带的贵阳为研究区,利用1980-2014年60种典型木本植物的始花期观测资料,分析了该地区植物始花期变化趋势及对气温变化的敏感度,评估了样本量大小对敏感度估计稳定性的影响。结果表明：①研究时段内贵阳发生了明显的气候变化,年平均气温显著升高,其中春、秋季的增温比夏、冬季显著。②绝大多数植物(88.3%)的始花期在研究时段内呈提前趋势,其中显著提前的占物种总数的21.7%(P<0.05);60种植物始花期总体的提前趋势为2.89 d/10 a。③绝大多数(88.3%)植物始花期的年际变化与最优时段内平均气温呈显著负相关(P<0.05),所有植物始花期的总体敏感度为-5.75 d/℃。④样本量大小对温度敏感度估计的稳定性有显著影响,15年长序列能将敏感度估计结果的波动范围以99%的概率控制在2 d/℃之内。 相似文献

基于NDVI的秦岭山地植被遥感物候及其与气温的响应关系——以陕西境内为例 总被引：3，自引：1，他引：2
《地理科学》2015,(12)
基于MODIS NDVI时间序列数据,利用动态阈值法提取秦岭山地2000~2010年的物候参数,并结合实测物候资料进行验证,在宏观尺度上量化了气温升高对植物物候的影响程度。研究得出:基于NDVI的物候变化趋势与实测物候资料结果一致;2000~2010年间物候始期提前的速率为0.165 6 d/a,末期推后速率为0.109 1 d/a;空间上,秦岭山地北部区域的植被物候始期主要发生在第120~130 d,相对于南坡较晚,物候末期主要发生在第300~325 d,北部区域物候末期的到来较迟,南部区域相对较早;物候始期NDVI与有效气温、春季、生长期气温相关性较好,末期NDVI与夏、秋季节气温相关性较好;气温对生长季开始阶段的NDVI在时间上存在2~3旬的滞后效应。 相似文献

贵阳木本植物物候对气候变化的响应 总被引：10，自引：0，他引：10
根据1978~2007年贵阳站的物候和气象资料,分析了贵阳站71种木本植物春秋季芽膨大期、展叶始期、始花期、叶完全变色期和落叶末期等5个关键物候期的变化趋势及其对气候变化的响应。结果表明:自1978年以来,贵阳年平均气温在振荡中明显下降,其中夏季气温降低最为明显,2月平均气温略有上升;春季芽膨大期、展叶始期和始花期等三种物候期均呈现出提前趋势,而秋季叶完全变色期和落叶末期呈现推迟趋势;春季物候期与物候期发生前若干月月平均气温的相关性较好,特别与当月和上月平均气温的相关关系最为显著。其中,2月月平均气温是影响春季三种物候期的关键指标,除此之外,贵阳站2、3月的日照时数也对春季物候期的提前起到促进作用;秋冬季物候期变化和气温、降水、日照时数的相关关系均不明显,这同秋季物候变化的复杂性和秋季物候期所受的影响因素较多有关。 相似文献

利用中国物候观测网观测数据,新编制了哈尔滨地区1985-2012年的自然历。通过与原自然历（1963-1984年）比较,揭示了近30年以来哈尔滨地区21个植物99个物候期的变化特征,并通过物候期与气温的相关分析探讨了物候变化原因。结果表明：自1985年以来,哈尔滨的春季、夏季、秋季的物候期开始日期提前,冬季开始日期推迟。其中春季（以白榆叶芽膨大期为代表）、夏季（以暴马丁香开花始期为代表）、秋季（以金银忍冬果实成熟期为代表）分别提前了7天、6天和19天,冬季（以胡桃楸落叶末期为代表）推迟了2天。各物候期在春季、夏季、秋季的平均日期相较于原自然历提前了3~11天,在冬季推迟了3天。四季各物候期最早日期均以提前为主,夏冬季物候期最晚日期有所推迟。另外,各季节内部分物候期出现的先后次序发生了变化。近30年该地区气温的升高是物候季节开始日期提前的首要原因。且不同植物和物候期对气温变化的响应敏感性不同可解释物候季节内物候期先后次序的变化。 相似文献

1965-2014年北京西郊地区植物观赏期对气候变化的响应 总被引：1，自引：0，他引：1
基于1965-2014年北京地区50种植物物候数据和同期日均温等气象资料,运用相关、回归分析法分析了北京地区绿叶观赏期、观花期和秋叶观赏期（开始日、结束日、时间长度）的变化趋势、变化形式及其对气候变化的响应情况。结果表明：① 北京西郊地区50种植物的绿叶观赏期为4月14日-10月15日,观赏期长度为163~219天。观花期为4月29日-5月17日,观花期长度为6~77天。秋叶观赏期为10月15日-11月14日,观赏期长度为16~41天。② 近50年来,北京西郊地区50种植物的3个观赏期都发生了一定程度的变化。绿叶观赏期开始日提前3.1天/10a,结束日推迟3.6天/10a,观赏期延长6.8天/10a。观花期开始日提前1.6天/10a,结束日提前0.5天/10a,观赏期延长1.2天/10a。秋叶观赏期开始日推迟3.6天/10a,结束日推迟1.1天/10a,观赏期缩短2.5天/10a。③ 绿叶观赏期延长主要表现为开始日提前,结束日推迟。观花期延长主要表现为开始日提前程度大于结束日提前程度,春花植物和夏花植物的观花期延长和缩短的表现形式基本一致。秋叶观赏期缩短主要表现为开始日推迟程度大于结束日推迟程度。④ 春季气温升高1 ℃,绿叶观赏期开始日提前3.9天、结束日推迟5.2天;观花期开始日提前3.4天,结束日提前1.9天。秋季气温升高1 ℃,秋叶观赏期开始日和结束日分别推迟5.2天和2.2天。⑤ 将不同观赏期重叠搭配可营造不同色彩和风格的植被景观,进而设计出不同特色的景观观赏主题。植物观赏期的变化可为园林景观创新设计提供有力参考,为植物观赏活动时间的安排提供科学依据。 相似文献

1964-2015年气候因子对秦岭地区植物物候的综合影响效应 总被引：4，自引：1，他引：3
以1964-2015年物候观测数据和逐日气象资料为基础,运用相关分析和PLS回归法,研究了秦岭地区植物物候变化与气候变化的响应关系。结果表明：① 1964-2015年,秦岭地区物候始末期的气候均呈干暖化趋势,且始期的暖化趋势较末期显著,物候突变后（1985年之后）尤为显著。② 就单一因素而言,物候始末期对气温、降水、日照等气候因子的响应程度存在差异,突变前（1985年之前）,除物候始期的日均温外,其他气候因子对物候的影响均不显著,但突变后影响显著,始期与末期的日均温每升高1 ℃,始期提前3.0 d,末期推迟12.0 d;始期的累积降水每减少1 mm始期提前1.3 d,末期的每增加1 mm末期推迟1.0 d;始期与末期的日均日照时数每增加1 h,始期提前4.3 d,末期推迟18.3 d。③ 气候因子对物候始末期的影响存在滞后效应,物候始期,气温影响的滞后时效约1~2个月,降水的滞后时效约1~3个月,而日照几乎无滞后效应;物候末期,气温的滞后时效约1~3个月,降水几乎无滞后效应,而日照影响的滞后时效约1~2个月。④ 物候始期与末期均受气温、日照、降水的综合影响,气温是影响物候变化最重要的因素,特别是同期日均温的升高对物候始期的提前及末期的推迟具有主导控制作用。 相似文献

气候变暖下东北地区春玉米生产潜力变化分析 总被引：18，自引：0，他引：18
在气候变暖的背景下,依据中国东北地区101个气象站点多年逐日气象数据,利用数理统计分析方法,研究了东北地区1971~2007年春玉米生长季气候变化趋势,包括春玉米生长季平均气温、太阳辐射总量和降水量的变化趋势;利用GIS技术分析了东北地区春玉米光温生产潜力及气候生产潜力的时空变化。结果表明,东北地区春玉米生长季气温呈波动上升趋势,其幅度超过全国平均值,太阳辐射呈减少趋势,降水量年际变化较大,有波动下降趋势。在气温不断升高的情形下,东北地区春玉米的光温生产潜力有所增加,但由于各地区间降水的差异,东北地区春玉米的气候生产潜力在各地区变化差异较大,21世纪以来相对于20世纪70年代,南部地区气候生产潜力减少,而中部地区增加。为此,就如何利用东北地区春玉米生产潜力的特点,以及提高春玉米的实际产量提出了一系列建议措施。 相似文献

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing. 相似文献
