The total number of publications was 2 052 from 1870-2001. Two peaks in the number of publications occurred during 1950-1965 and 1978-2001, respectively. In 2 052 publications, most of them were published by the science-research sector, accounting for 54.2% of total publications. The percentage of publications from the science-research sector has been increasing over time, however, the contribution from the foreign sector has produced a contrary trend. Over 9% of total publications were indexed by SCI. The highest percentage of publications indexed by SCI took place during 1966-1977. In all publications indexed by SCI, those from the science-research sector dominated other sectors (59.1% of total publications). However, the foreign sector led with 30.1% of its own publications being in SCI. Studies of primatology were divided into nine areas. The percentage and change in percentage of publications in areas of primatology were counted. During 1978-2001 ecology and behaviour, neurobiology, reproduction and captive feeding were rapidly developing;fossil primates, morphology and anatomy decreasing;and taxonomy and distribution, cellular and molecular evolution became relatively poor. Increasing attention was paid to conservation biology. Prevention and control of diseases was fairly well studied in periods Ⅱ (1950-1965) and Ⅳ (1978-2001). The number of authors was highest during period Ⅳ, however, the mean number of publications per author in period Ⅳ was not as high as in period Ⅰ (1870-1949). Generally speaking, Chinese authors dominated the authors included in SCI. However in period Ⅰ, the sole author indexed by SCI was a foreign scholar, and foreign scholars comprised 60% of indexed authors in period Ⅲ (1966-1977).展开更多

However, the relationship between spatial variation of soil moisture, vegetation restoration type and slope length is controversial. Therefore, soil moisture across soil layers(0-400 cm depth) was measured before and after the rainy season in severe drought(2015) and normal hydrological year(2016) in three vegetation restoration areas(artificial forestland, natural forestland and grassland), on the hillslopes of the Caijiachuan Catchment in the Loess area, China. The results showed that artificial forestland had the lowest soil moisture and most severe water deficit in 100-200 cm soil layers. Water depletion was higher in artificial and natural forestlands than in natural grassland. Moreover, soil moisture in the shallow soil layers(0-100 cm) under the three vegetation restoration types did not significantly vary with slope length, but a significant increase with slope length was observed in deep soil layers(below 100 cm). In2015, a severe drought hydrological year, higher water depletion was observed at lower slope positions under three vegetation restoration types due to higher transpiration and evapotranspiration and unlikely recharge from upslope runoff. However, in 2016, a normal hydrological year, there was lower water depletion, even infiltration recharge at lower slope positions, indicating receiving a large amount of water from upslope. Vegetation restoration type, precipitation, slope length and soil depth during a rainy season, in descending order of influence, had significant effects on soil moisture. Generally, natural grassland is more beneficial for vegetation restoration than natural and artificial forestlands, and the results can provide useful information for understanding hydrological processes and improving vegetation restoration practices on the Loess Plateau展开更多

For a better understanding of the cause, this study investigates the dynamic changes of Baiyangdian Lake wetland over the last 40 years. It is shown that since the 1980s, Baiyangdian Lake has suffered from an insufficient water input and shrunk considerably. By using SPSS 11.0, this study urines a detailed Analysis on the signifficance of the effects of the possible driving factors for the degradation. It is identified that the North China Plain has been warrnin~ up significantly in recent years, which causes a significant reduction in the precipitation and inflow to the lake. Although human disturbances such as the irrigation and storage of water in reservoirs do not play a decisive role, they accelerate the degradation and their effects should be minimized.展开更多

As a literature trend, local novels open a new road for realistically sentimental novels of view literature. Therefore, this paper is aim to study the Local Colorism American Novels of 19th Century, especially in west and south of American. American southern literature and western literature although established respectively unique sense of place suffer from complex history. And it proves that American literature has been increasingly building it popularity and a new type of literature.展开更多

Outdoor climate has conducted man to build along the time a habitat climatic responsive. Nowadays, studies in progress try to show how this vernacular typology can support new low-income house designs. The intent is to guarantee for new projects the socio-cultural image that people, coming from countryside to live in city outskirts, are accostumed. Also, to provide material improvements and functional adequation for a quality and healthiness. Natural ventilation is the main bioclimatic strategy during summer for thermal comfort, which influences the house characteristics. This is proven by calculation, and simulation with the CFX-ANSYS software. Thus, the analysis performed shows the real possibity to reconcile bioclimatism with the symbolic-cultural value represented by this vernacular architecture form. It is hopped that this study can be considered as a methodological contributition for new sustainable projects (materials, technics and services) of low-incoming houses in this Latin American region.展开更多

Attributive-center, combination, apposition and subject-predicate are its main structure types. In main literary genres, the distribution of N+N nominal sentence shows a certain trend of dominant hierarchy: poem﹥drama﹥novel﹥prose. No matter what kind of literary genres, attributive-center structure is the type with maximum quantity, while appositive structure is the type with minimum quantity. Statistical result indicates that most of N+N nominal sentence is nominal and its use is limited by genres. Function of N+N nominal sentence is textual. When it comes to discourse, it can be used as theme, rheme and dual identity of theme and rheme based on the theory of Theme-Rheme (T-R) structure pattern. It does not only construct the information structure to deliver textual information, but also its a vital means of discourse cohesion and coherence.展开更多
