摘要：
Marine Isotope Stages (MIS) 9 has been proposed as an analog for the present warm period. However, detailed studies of this geological time period are rare in loess-paleosol sequence. In the Chinese Loess Plateau (CLP), the corresponding stratum is the third paleosol layer (S3). Here, we report the terrestrial reconstruction of climatic fluctuations during MIS 9 by analyzing the paleo-climate indexes of S3 with high sampling density. Our results showed that: (1) During the period of MIS 9, the main climatic sub-cycle was 29 ka; (2) MIS 9 could be divided into five sections, MIS 9a, 9b, 9c, 9d, and 9e. Among them, MIS 9a, 9c, and 9e were warm stages, while MIS 9b and 9d were cool intervals; and 3) There were also three swift warm-wet events and one cool-dry event, which occurred around 332-331, 324-323, 311-310, and 331-329 ka BP, respectively. The overall trend of paleo-climate fluctuation correlated approximately with SPECMAP, LR04 stack and Iberian margin deep-sea cores. This study suggested that the paleosol records in the southern margin of the CLP have global significance and contain more detailed climatic signals than marine deposits.

摘要：
Gully erosion, a spectacular erosional landform in the hilly areas of southern China, poses an enormous threat to local sustainable economic development and ecological security. The depth of granite weathering mantle in-creases from north to south, which is consistent with the increase of gully density and accelerated soil loss. However, the spatial distribution of soil depth in gully areas remains unclear. Herein, soil depth was measured by field sampling investigation, and soil depth mapping was established using the Fuzzy c-means algorithm. To explore the relationship between soil depth and gully erosion rate, gully characteristics and erosion process were monitored by unmanned aerial vehicle. The results showed that the gully density increased from Tongcheng (29 degrees 2 & PRIME;- 29 degrees 24 & PRIME; N) to Wuhua (23 degrees 23 & PRIME;- 24 degrees 12 & PRIME; N) in the range of 11.25-61.75 gullies/km2, in contrast to an opposite trend in the soil depth range from 180 to 5 cm. Additionally, soil depth mapping by fuzzy c-means algorithm performed well in gully areas, with overall accuracy, Pearson correlation coefficient, and agreement coefficient reaching 81.60%, 0.90, and 0.97, respectively. Moreover, the gully erosion rate in the range of 7.60-29.08 m3 yr.-1 had a significant positive linear relationship with the area of collapsing wall (R2 = 0.54, p < 0.05). Based on this relationship, a power function was established between soil depth and gully erosion rate (R2 = 0.41, p < 0.01), which provides a possibility for effective prediction of gully erosion. This study facilitates a better understanding of the gully erosion mechanism and its effective control.

摘要：
High-quality regional development should be promoted by facilitating inter-regional mobility of heterogeneous labor force to optimize its spatial allocation. This study incorporates skill relatedness into spatial categorization and selection effects, and explores how skill-relatedness affects the location choice of heterogeneous labor force. To do so, we use labor force migration data and employee data by occupation subcategory from the 2000 National Population Census and 2015 National Population Sample Survey. The empirical evidence provides three major findings. First, there are significant regional differences in labor migration rates by the occupational group between cities in China, and the trend is increasing. Regional concentration of location choice is increasing and six significant agglomerations are formed. Second, skill relatedness positively affects the location choice of the heterogeneous labor force in Chinese cities. When cities' skill-relatedness is more robust, influence on labor location choice is more remarkable. In cities with high-size classes, the effect of high-skill relatedness on labor location choice is higher. Third, labor force with solid skill relatedness with regional employment moves to the location owing to the spatial sorting effect. Labor force without skill relatedness or weak relatedness moves out or does not move to the location owing to the spatial selection effect.

摘要：
This study constructs a theoretical framework for the production and reconstruction of food cultural space from a glocalization perspective. Through a qualitative analysis, we analyse the practice and representation of food cultural space in Yanji City. The results show that food cultural spaces have evolved from commercial residential to open urban leisure consumption spaces through a leap from a quantitative to a qualitative change.It integrates fashionable cultural consumption elements into the optimisation and expression of urban space extension, thus achieving the spatial image of symbolic communication. As the representational space of residents’ daily life, the evolution of food cultural space is accompanied by capital multiplication, power cultivation, and class mobility, which play an important role in promoting urban space expansion and social structure renewal. The results enrich the research on food cultural space under the background of glocalisation and provide a reference for the sustainable development of urban cultural space.
