为了探讨个体出生时间、采食干扰及有性生殖等过程对个体寿命的调节作用,本试验以东北退化草地广布种猪毛蒿(Artemisia scoparia)为研究对象,开展不同播种时间和不同去顶频次的实验种群,以及不同程度放牧干扰下天然种群繁殖和个体存活特征的比较研究。研究表明:播种时间处理中,早春播种种群结实后当年全部死亡,春末以后播种的结实后部分死亡;去顶处理中,无论是对照,还是1,2次去顶处理结实后均部分死亡;延迟播种时间降低了花序生物量分配和种子生物量分配比例,但去顶干扰对两种繁殖分配均有促进作用;天然种群中,3龄级植株繁殖分配比例下降,但是种子产量增加,分别是2龄级3.6倍和1龄级3.1倍。猪毛蒿种群中个体出生时间和繁殖分配策略都会影响个体寿命,个体死亡是生殖消耗过多养分所致。

为了评估无性系实际营养繁殖力对植物种群增长的影响,本文基于同质园建立的赖草(Leymus secalinus)实验同生群,以单个无性系营养繁殖指标衡量实际营养繁殖力,分析了两个年份赖草单个无性系构件生产和生长的阶段性和连续性增长规律,并构建芽流模型。结果表明,赖草无性系在当年和翌年根茎总长度、根茎数、芽数等营养繁殖指标均具有较大可塑性,变异系数均大于74%。在年份间,实际营养繁殖力的增长大于营养繁殖力的增长。在根茎生长序列中,根茎总长度、根茎数、分株数、活芽总数、活构件总数的阶段性和连续性增长过程均符合指数模式。在芽流中,两个年份赖草无性系营养繁殖失败率均低于1%,而成功率均较高,当年为40.6%,翌年为58.1%,其中,分株输出率分别是根茎的4.3倍和5.5倍。无性系实际营养繁殖力的可塑性体现了植物种群生存对策,小无性系采取优先占据更多地上空间的策略。

衰老是植物重要的生活史阶段,植物不同器官养分贮藏力及活动力是判断个体衰老的重要依据。目前对于无性系植物不同龄级分株在衰老过程中贮藏器官的贮藏力与活动力的变化规律尚不清楚。全叶马兰(Aster pekinensis)是根蘖型无性系植物,在东北草原,全叶马兰种群主要由3个龄级的分株组成。该研究分析了全叶马兰种群中3个龄级分株(1a、2a和3a分株)的茎基部、根颈和主根中可溶性碳水化合物(WSC)含量在贮藏器官间、龄级间的差异及季节变化规律。结果表明:在枯黄期,全叶马兰种群3个龄级分株中主根的WSC含量普遍大于根颈,根颈和主根的WSC含量均为1a、2a分株显著高于3a分株,1a分株茎基部的WSC含量显著低于2a和3a分株。在整个生长季内,随着生长进程,全叶马兰种群1a分株根颈始终获得养分的优先分配,其WSC含量呈指数形式的持续积累过程,2a和3a分株根颈及3个龄级分株主根在WSC运转上均为先消耗再积累,其WSC含量均呈二次曲线节律消长。全叶马兰3个龄级分株普遍为主根的贮藏力大于根颈,而根颈的活动力大于主根。幼龄分株养分贮藏力和活动力最强,壮龄分株无衰老迹象,老龄分株明显衰老,其养分贮藏力和活动力均显著下降。该研究为了解WSC含量的时空变化与植物种群个体衰老过程的关系提供了一种定性与定量相结合分析的新思路。

公路交通运输与旅游业的协调发展对区域经济的发展具有重要意义。对于两者之间较为复杂的耦合协调关系的相关研究也一直受到广泛关注。为能够正确认识公路交通运输与旅游业两者之间的耦合协调关系,探索两者之间的耦合协调作用机理,促进两者的可持续协调发展,为此,构建了新疆公路交通运输与旅游业发展评价指标体系,并借助熵值权重法及耦合协调模型,对2010年~2020年新疆公路交通运输与旅游业耦合协调发展状况进行了相关深入分析。从研究结果来看,新疆公路交通运输与旅游业耦合协调度整体呈现上升发展趋势,主要经历了2010年的失调衰退阶段,2011年~2015年的过渡阶段和2016年~2020年的协调发展阶段3个阶段。2020年受到“疫情”不可抗力因素影响,公路交通运输与旅游业耦合协调度有所下降,相应等级由优质协调发展降低到初级协调发展,但总体趋势还是属于协调发展阶段。通过本研究,可以清楚了解到新疆公路交通运输与旅游业之间的耦合协调发展状态,为今后促使两者耦合协调度发展达到优质效果,提供相关措施建议。
