【目的】探究近成过熟杉木(Cunninghamia lanceolata)林中草药种植活动(包括相关的割灌除草、整地、施肥、日常抚育和林下作物生长等)对林木单株材积生长产生的综合影响。【方法】在浙西南景宁畲族自治县境内的大漈林场与草鱼塘林场近成过熟杉木人工林中,分别设置有3年林下种植中草药和没有林下种植的各10个样地,每个样地选择1株平均木进行树干解析,基于最近3年的材积连年生长量采用适应性强的线性模型方法,进行林下种植的影响评价。【结果】在同时考虑林木年龄、胸径、树高、密度、地位指数等因子的前提下,林下中草药种植活动对单株材积生长具有显著的促进作用。【结论】林下种植活动可显著促进近成过熟杉木林单株材积生长,有利于大径材培育,但这种促进作用受到林木年龄的制约。线性模型方法适用于情况复杂、无法对试验进行严格控制情况下的数据分析,但在小样本情况下使用线性模型方法需要在建模过程中对数据进行一系列是否满足条件的检验,对不满足要求的数据需采用一定方法进行调整。

随着近成过熟林等大龄林分的不断增加和幼中低龄林分的减少,大龄林分林下种植逐渐增多,但针对大龄林分林下种植对林木生长影响的研究较少,且存在新的研究难点。本文基于小样本线性模型方法,探讨大龄杉木Cunninghamia lanceolate林下种植中草药对林木胸径生长的影响问题。2021年,在浙西南景宁畲族自治县境内的大际林场与草鱼塘林场大龄杉木人工林中设置了有3年林下种植中草药和没有林下种植的样地各10个,每个样地做1株平均木解析木,基于解析木最近3年的胸径连年生长量,在对数据进行适用性检验、并对不符合要求的数据进行变换处理后,建立线性模型分析林下种植对胸径生长的影响。结果表明,对不满足线性要求的年龄进行变换消除非线性后的线性模型质量有明显提升,并在此基础上,发现林下中草药种植对胸径生长具有显著的促进作用,但这种作用受到林木年龄的影响和制约。线性模型方法适用于情况复杂、无法对实验进行严格控制情况下的数据分析,方法灵活,但在小样本情况下需要满足一系列条件,若不满足则必须先对数据进行处理以满足条件。

Previous carbene insertion to C–H bonds of 1,3-azoles relied on metal carbene species. Herein, we report a metal-free C（sp2）–H bond functionalization of 1,3-azoles with trifluoroacetylsilanes. The reaction features mild conditions, broad substrate scope and wide functional group tolerance. The mechanistic study supports that the success of the reaction is probably attributed to the dual roles of trifluoroacetylsilanes under the photocatalyzed conditions: generating carbenes which undergo cyclopropanation and generating biradicals which promote ring-opening aromatization of the in situ generated fused cyclopropanes.

We investigate the observational appearance of static and spherically symmetric hairy black holes in the framework of gravitational decoupling with the weak energy condition(WEC). Two types of thin illumination conditions are studied: spherical accretion and disk accretion. As the hairy parameter increases, the size of the photon sphere and photon rings in both models decreases, and the overall luminosity attenuation becomes more pronounced. In spherical accretion, the luminosity of infalling accretion is significantly lower than that of stationary accretion. In disk accretion the luminosity of the black hole is contributed by direct emission, the lensing ring and the photon ring. Employing four types of astrophysical disk luminosity model,we investigate the appearance of halos and note that their luminosities do not superimpose when the source is on or beyond the innermost stable circular orbit.
