本文提出了一种基于Azure Kinect传感器无损测量三维点云的表型参数测量方法。该方法包括预处理、茎叶分割和表型参数计算3个步骤。首先通过预处理将植株点云从场景点云中提取出来,在茎叶分割步骤历经骨架化、骨架修剪、茎线识别和叶片分割几个分步骤将木荷植株的茎干和叶片分离,最后得到株高、茎长、茎的方向、叶长和叶角等表型参数。实验结果表明,每个参数的决定系数(R~2>0.85)和均方根误差(RMSE)均达到了精度要求,说明了该方法是稳健和准确的。

森林生产力和碳汇功能在很大程度上取决于土壤氮和磷的有效性。然而,迄今为止,养分限制随森林演替的时间变化仍存在争议。叶片化学计量和养分重吸收是预测植物生长养分限制的重要指标。基于此,本研究测定了温带森林4个演替阶段所有木本植物叶片和调落叶中氮和磷的含量,并分析了演替过程中非生物因子和生物因子如何影响叶片化学计量和养分重吸收。研究结果表明,在个体尺度上,叶片氮磷含量在演替末期显著增加,而叶片氮磷比无显著变化氮的重吸收效率随演替显著增加,然而磷的重吸收效率先增加后减少:氮重吸收效率与磷重吸收效率的比值仅在演替末期显著增加。此外,植物氮素循环对土壤养分的响应比磷素循环更弱。在群落尺度上,叶片氮磷含量随森林演替呈现先降低后升高的趋势,主要受香农-维纳多样性指数和物种丰富度的影响:叶片氮磷比随演替而显著变化,主要由胸径的群落加权平均值决定:氮的重吸收效率增加,主要受物种丰富度和胸径的影响,而磷的重吸收效率相对稳定。因此,氮重吸收效率与磷重吸收效率的比值显著增加,表明随着温带森林演替,氮限制加剧。这些结果可能反映了较高生物多样性群落中物种间对有限资源的激烈竞争,强调了生物因子在驱动森林生态系统养分循环中的重要性,为中国温带和北方森林可持续经营的施肥管理提供了参考。

Variations in seed size and seed mass related to tree growth over 5 years for 23 provenances of Quercus acutissima from across China

Journal of Forestry Research 2017年第5期28卷 917-924页

作者： Hui Zhang Xiuqing Yang Mukui Yu Youzhi Han tonggui wu Research Institute of Subtropical Forestry Chinese Academy of Forestry Forestry College Shanxi Agriculture University

The origin of a seed strongly impacts its traits, and both origin and seed traits influence seed germination and seedling development. However, in many instances, this effect on the seedling does not persist into adulthood, and little is known about how seed traits and original environment affect seedling/tree growth over time. In this study, seed size, seed mass, seedling/tree growth and origins were collected and determined for 23 provenances of Quercus acutissima from across China. Origin variables correlated well with seed size and seed mass. In stepwise multiple regressions, a longitudinal aridity index explained 49.2-68.7% of the total variation in seed size and mass, while only seed width was correlated with seedling/tree height (H) and diameter at the ground (D) from seed traits and origins. The total variance in H and D explained by the models decreased over time, for example, the R 2 value of the models for H declined from 0.477 in the first year to 0.224 in the fourth year; no models was significant in the fifth year. These results indicate that seed size, regulated by the longitudinal aridity index strongly impacted seedling and tree growth, but the strength of the influence decreased over time, and disappeared after 4 years.

森林群落的物种多样性和结构多样性是影响野生动物栖息地选择的重要因子,以往针对黑麂(Muntiacus crinifrons)栖息地特征的研究多探讨森林类型对黑麂出现概率的影响,而针对反映森林群落特征的微生境因子的研究相对匮乏。本研究基于钱江源国家公园164个位点的红外相机监测数据和20 m×20 m植物长期监测样方数据,从物种多样性和结构多样性两个维度研究了4种主要森林类型(常绿阔叶林、常绿落叶阔叶混交林、针阔叶混交林、针叶林)的木本植物群落特征及其对黑麂出现概率的影响。结果表明:常绿阔叶林木本植物的物种多样性显著高于针叶林(P<0.05),其结构多样性显著高于常绿落叶阔叶混交林、针阔叶混交林和针叶林(P<0.05),其余森林类型间的物种多样性和结构多样性均无显著差异。样地内木本植物的物种多样性和结构多样性之间无明显相关关系。对黑麂微生境特征的分析结果显示,黑麂偏好常绿阔叶林和常绿落叶阔叶混交林,且海拔和坡度越高其出现概率越高;木本植物胸径Shannon多样性指数越大、胸径<5 cm木本植物平均胸径越大时,黑麂的出现概率越高,表明黑麂偏好结构多样性高、林下植被个体长势良好的森林。本研究结果对钱江源国家公园黑麂的栖息地恢复和管理、廊道选址和建设有一定的指导意义。

滨海滩涂由于其高含盐量显著影响了植物群落分布及生物多样性。目前有关滩涂含盐量与生物多样性的关系研究较多,但不同区域盐基离子组成不同,且对植物的影响也存在较大差异,以杭州湾南岸不同年代形成的滩涂为研究对象,系统监测了50个样方土壤交换性盐基阳离子的组成、分布和植物组成及多样性特征等,采用去趋势典范对应分析(DCCA)、线性回归和多元逐步回归分析了4种盐基阳离子对物种数量、分布和多样性的影响。结果表明,杭州湾南岸滩涂4种主要盐基阳离子含量(g/kg)大小顺序为Ca2+>Na+>Mg2+>K+,其中Ca2+占到总含量的61.97%;经DCCA分析发现4种盐基阳离子对植物群落的分布均有显著影响,但以Ca2+的影响程度最大;随着盐基离子含量的逐渐降低,物种数量逐渐增加,多样性指数逐渐增加,同时也发现Ca2+对两种多样性指数影响最大。
