建构中国电影的类型化空间——以武侠电影酒馆、茶馆、饭馆等市井空间为例

空间文化是空间社会生产的重要产品,电影是生产空间文化的重要媒介,视听语言呈现的空间必然带有空间被赋予的社会属性和意义。武侠电影中的酒馆、茶馆、饭馆等市井空间,在电影中既以实用性场所出现并发挥其现实功能产生叙事,同时又能够作为电影的叙事空间催生人物新的行为活动推进叙事。空间的类型化在于相近的空间结构与形态能够给人相似的空间体验,建构中国电影类型化空间则需寻找到中国人对空间的独特认知方式。

汉英时间词空间化特质及其语言蕴含共性

文章从跨语言视角,定量探究汉英时间词的空间化特质及其语言蕴含共性,并试图探析其衍生缘由。语料分析表明:1)汉英时间词内部均有空间化等级性,并且偏好空间方位时间词;2)汉语时间词的空间化程度高于英语,前者空间化类型较之后者更为活跃;3)汉英时间词遵循如下蕴含共性:时间词空间化→空间方位时间词。上述发现能昭示汉英时间词的空间化程度和类型异同,揭示时间词空间化与空间方位时间词的内在关联,并能阐释时空映射和汉英时空性思维特质差异对时间词空间化的交互影响,具有一定的理论和现实意义。

SPATIO-TEMPORAL VARIATION CHARACTERISTICS OF EXTREMELY HEAVY PRECIPITATION FREQUENCY OVER SOUTH CHINA IN THE LAST 50 YEARS

This paper comprehensively studies the spatio-temporal characteristics of the frequency of extremely heavy precipitation events over South China by using the daily precipitation data of 110 stations during 1961 to 2008 and the extremely heavy precipitation thresholds determined for different stations by REOF, trend coefficients, linear trend, Mann-Kendall test and variance analysis. The results are shown as follows. The frequency distribution of extremely heavy precipitation is high in the middle of South China and low in the Guangdong coast and western Guangxi. There are three spatial distribution types of extremely heavy precipitation in South China. The consistent anomaly distribution is the main type. Distribution reversed between the east and the west and between the south and the north is also an important type. Extremely heavy precipitation events in South China mainly occurred in the summer-half of the year. Their frequency during this time accounts for 83.7% of the total frequency. In the 1960 s and 1980 s, extremely heavy precipitation events were less frequent while having an increasing trend from the late 1980 s. Their climatological tendency rates decrease in the central and rise in the other areas of South China, and on average the mean series also shows an upward but insignificant trend at all of the stations. South China's frequency of extremely heavy precipitation events can be divided into six major areas and each of them shows a different inter-annual trend and three of the representative stations experience abrupt changes by showing remarkable increases in terms of Mann-Kendall tests.

Urbanization of Jilin Province and Its Spatial Pattern

Urbanization is a crucial criterion of assessing a nation’s or a particular region’s level of modernization.It has been accelerated all over the world in the 21th century.The main purpose of this research is to provide a strategy of spatial pattern of urbanization for rural areas in Jilin Province based on the reality of economic development in Jilin and the im-balance of natural resources distribution.The strategy divides the nine central cities of Jilin Province into three economic circles.The outer economic circle,open circle,includes Yanbian,Baishan,Tonghua and Baicheng,covering the eastern and western parts of Jilin Province.The middle one includes Jilin,Liaoyuan,Siping and Songyuan.The inner one,centring as Changchun,includes Gongzhuling,Yitong,Nong’an,Jiutai and Dehui.It needs to centre as Changchun which has the good foundation of economic development and more economic increase,then by economic effect extending out gradually,other areas develop subsequently.To construct Jilin as a green ecological province,cultivation in the outer circle should be con-trolled,with the main aim to recover grassland.Large population should be moved to other places by developing labor economy.From economy and ecology,to decrease the load of the land can reduce the loss of the resources and benefit the balance of ecology.Subsequently,the whole province’s economy will be developed sustainably.

Dynamic Change of Landscape Pattern at Jilin Province from 1980 to 2000

By using remote sensing images from three periods (1980, 1995, 2000) and with the support of GIS and RS, the spatial information of landscape elements of Jilin Province from 1980 to 2000 was interpreted and extracted. Using models of landscape indices such as diversity, fragmentation, and mean patch fractal dimension, dynamic spatio-temporal changes of landscape patterns of the province were analyzed. The results: ① cropland and forestland were the main landscape types, and forestland became a landscape matrix; ② in the study area, landscapes were distributed unevenly, and there was low heterogeneity, a simple ecosystem structure and a tendency of irrational landscape patterns. There were also simple spatial shapes of patches and strong self-similarities, and in terms of dynamic change analysis, patch shapes tended to be more simple; ③ from 1980 to 2000, holistic landscape fragmentation was low and changed slightly. As far as landscape elements were concerned, the fragmentation of grassland, water area, land for residential area and factory facilities was relatively low; land distribution for residential areas and factory facilities was dispersed; and cropland and forestland were most concentrated-an indication that the trend will continue. Comprehensive effects among human activity, local policy, regional climate and environmental change led to the results.

Road Impacts on Spatial Patterns of Land Use and Landscape Fragmentation in Three Parallel Rivers Region,Yunnan Province,China

The structure and function of network is a central issue in landscape ecology.Road networks with hierarchical structure are crucial for understanding landscape dynamics.In this study,we compared the distribution of national road,provincial road,county road and rural road in the Three Parallel Rivers Region(TPRR)in Yunnan Province of China,and estimated the effect of roads(and other factors)on the spatial patterns of land use and land cover with logistic regression.In addition,we analyzed the land use and land cover change(LUCC)and landscape fragmentation in 1989–2005 along a buffer zone of the primary traffic corridor,national road G214.The results showed that,county and rural roads had much higher percentage of length extending into more natural habitats at higher elevation and steeper slope,compared with the higher level roads in this region.While the distributions of natural land cover types were dominated by environmental factors,human land use types i.e.,building land and farmland types were significantly related with roads,linking more closely with lower level roads.The LUCC dynamics(1989–2005)of the G214 buffer zone showed a general trend of land transformation from conifer forests and valley arid shrubs to building land and farmland,and from ice and snow to alpine shrubs and forests.With the length of G214 unchanged during the time,the overall landscape pattern changed little in the buffer zone,but habitat fragmentation and area decrease had occurred for the natural vegetation types,in contrast to patch mergence and expansion of human land use types,and landscape fragmentation was intensified above 2500 m a.s.l.but declined below the elevation.The results indicated the dynamics of landscape composition and patch type level distribution in spite of the stability of the overall landscape pattern,and implied the potential role of roads,especially the low level roads on landscape changes.

Existence of global solution to a two-species Keller-Segel chemotaxis model

In this paper, we investigate the global existence of nonnegative solutions of a two- species Keller-Segel model with Lotka-Volterra competitive source terms. By raising the regularity of a solution from L^1 to L^p（p〉1）, the existence and uniqueness of the classical global in time solution to this chemotaxis model is proved for any chemotactic coefficients X1, X2 〉 0 when the space dimension is one. Furthermore, it is shown that the model has a unique classical global solution in two and three space dimensions if the chemotactic coefficients X1 and X2 are small as compared to the diffusion coefficient d3 of the chemoattractant.
