TL;DR: In this article, the species composition of undergrowth vegetation and dominant species in plantations in Datong were studied preliminarily by plots and line transect method, the results showed plantation provided the necessary place where herb and shrubby grow and succession of plant community.
Abstract: Species composition of undergrowth vegetation and dominant species in plantation in Datong were studied preliminarily by plots and line transect method,the results showed plantation provided the necessary place where herb and shrubby grow and succession of plant community.Undergrowth vegetation type of coniferous forest were shade tolerance plant under Picea purpurea,Larix principis pure forest and Picea purpurea ×Larix principis mixed forest,undergrowth vegetation type of broadleaf forest were liking light weed under Populus cathayana and Betula platyphylla pure forest,undergrowth vegetation type of mixed forest as Populus cathayana×Hippophae rhamnoides,Populus cathayana×Picea crasfolia,Betula platyphylla× Picea crasfolia were sciadophylous plants,undergrowth vegetation biomass of broadleaf pure forest relatively large,and that of coniferous pure forest and mixed forest were relatively small.

TL;DR: In this paper, the mean total organic carbon storage in the eucalyptus plantation ecosystem was 88.84 t·hm-2, of which there was 23.13%(20.55 t·m-2) stored in the arbor, 1.74%(1.93 t·h2) in litters, and 72.81%(64.82%) in the soil.
Abstract: Based on the investigated data of 54 plots of 18 sites in the west coastal area,north plain area,east coastal area and central mountainous area of Hainan Island,the biomass,carbon storage,carbon sequestration and spatial distribution of eucalyptus plantations in Hainan Island,southern China were analyzed.The results indicated that the mean total biomass was 49.72 t·hm-2,and the biomass distribution of the forest system showed such a sequence as:arbor layer(85.10%)litters(8.08%)undergrowth layer(6.82%).The mean total organic carbon storage in the eucalyptus plantation ecosystem amounted to 88.84 t·hm-2,of which there was 23.13%(20.55 t·hm-2) stored in the arbor,1.74%(1.55 t·hm-2) in undergrowth vegetations,2.17%(1.93 t·hm-2) in litters,and 72.96%(64.81 t·hm-2) in the soil(0-100 cm).The stem had the biggest organic carbon storage of the total carbon storage in various plant organs,accounted for 52.81% of carbon storage in arbor layer.The mean annual net productivity of eucalyptus plantations was 17.56 t·hm-2a-1,with a mean annual stored carbon up to 8.43 t·hm-2,amounted to 30.91 t CO2·hm-2a-1.The total organic carbon storage and sequestration of the eucalyptus plantations of Hainan Island was 2 958.37×104 t and 280.97×104 t·a-1,respectively.The carbon sequestration of eucalyptus plantations in the central mountain area(11.89 t·hm-2a-1) was largely higher than other three areas,such as the northern plain area(8.97 t·hm-2a-1),the western coastal area(7.18 t·hm-2a-1) and the eastern coastal area(8.26 t·hm-2a-1).The three areas had no significant difference in the carbon sequestration.Except for the western coastal area and the eastern coastal area,the carbon storage among all other areas was significantly different,mainly because of their different carbon storage of soil.

TL;DR: In this article, the influence of teaching on the female identity of Anna Vorontosov, the protagonist of Sylvia Ashton-Warner's Spinster, is examined, and detailed attention is paid to how the peculiarities of Anna's teaching method contribute to her enhanced experience of the semiotic and shape her female self.
Abstract: The aim of this paper is to scrutinise the influence of teaching on the female identity of Anna Vorontosov, the protagonist of Sylvia Ashton-Warner’s Spinster. Kristeva’s theory of the semiotic and the symbolic is referenced to argue that the work of a teacher enables the heroine to transcend the patriarchal model of experience, predicated on rationality, self-restraint and stability. Through teaching, Anna renews her bond with the semiotic, surpassing the bounds of a unitary and fixed self. After providing an overview of Ashton-Warner’s own career in education, the paper analyses the tensions inherent in the role of a female teacher as represented in the novel and explicates them in Kristevan terms. Subsequently, detailed attention is paid to how the peculiarities of Anna’s teaching method contribute to her enhanced experience of the semiotic and shape her female self.

TL;DR: In this paper, the authors investigate undergrowth vegetation in the forests with different densities in semi-arid region on the loess plateaus, and analyze the niche of undergrowth plants.
Abstract: Based on the investigating undergrowth vegetation in the forests with different densities in semi-arid region on the loess plateaus,the niche of undergrowth vegetation are described and analyzed,with different densities as the resource state and with the important value as the resource state descriptor of the niche.The results indicate that most of undergrowth vegetation have lower niche breadth values,but Heteropasppus altaicus and Arremisia sacrorum have higher niche breadth values,59.7% of the herbage species have niche overlaps,but which are lower.All the above reveal that the bad condition of undergrowth vegetations.
