Since the impoundment of the Three Gorges Reservoir(TGR), the riparian zone has been subjected to numerous environmental changes. This study was conducted to recognize the distribution of grass roots and its impacts on soil nutrients in the water level fluctuation zone of TGR. Roots of four predominant herbaceous plants in the study area, specifically, Cynodon dactylon, Hemarthria altissima, Hemarthria compressa, and Paspalum paspaloides, and their corresponding relation with soil nutrient contents were investigated. Root surface area density was determined with Win RHIZO, and the relationships of root distribution with soil depths and soil nutrient contents were studied. The results indicates that most roots are distributed in the top soil layer of 0-10 cm. Estimated root surface area density for the selected grass species ranges from 0.16 to 13.44 cm^2/cm^3, and decreases exponentially with an increase in soil depth. Soil organic matter and total nitrogen contents are significantly lower on bare control area than the corresponding values on the grasslands. Total nutrient contents on grasslands of C. dactylon and H. compressa are higher than those of other grass areas. Root length density and root surface area density are significantly correlated with soil organic matter and total nitrogen content for the four grasslands. The present results suggests that plant roots have significant effects on the distribution of soil nutrients in soil profiles in the riparian zone along the TGR. Nevertheless, additional investigations are needed to reveal the specific interactions between plant roots distribution, soil nutrients and water level fluctuations. 展开更多

A better understanding of the regional disparity and imbalance characteristics of China's urbanization development is the important premise for constituting correct policy and strategy and promoting the healthy and sustainable development of urbanization in the 21st century. The regional differences of China's urbanization level have close relations with natural conditions of landform and climate etc.,the urbanization level reduces with the eleva-tion of topography and decrease of precipitation. According to the statistical data set of ur-banization in 1950-2006,the temporal change course of inter-provincial disparity of Chinese urbanization level since the founding of New China in 1949 was studied,and then the inter-regional and intra-regional disparities of urbanization development were analyzed by the Theil index and its nested decomposition method,to grasp the dynamic change of spatial disparities of China's urbanization level on the whole. Using the imbalance index model,the imbalance status of urban population distribution relative to total population,grain output,total agricultural output value,gross output value of industry,tertiary industrial output value as well as gross regional product was discussed,to hold the balance characteristics of urbanization development relative to the regional development conditions from the macroscopic scales. 展开更多

This paper systematically reviews the different stages of China's urbanization process since 1949, its achievements and problems it faces. It offers in-depth discussion on the trends of Chinese urbanization, i.e. maintaining rapid growth; making small and medium- sized cities the main driver in development; and focusing on central and western China as the major areas to be urbanized. This paper analyzes new-type urbanization for instance to set up comprehensive urban system that meets the requirements of having a high urbanization level, such as focusing on developing medium-sized cities of one to two million people, using city clusters to encourage population concentration and following an urban construction model that is intensive and compact; and finally this paper proposes policy suggestions for boosting the healthy development of new-type urbanization, including reforming current models for urban-rural governance and establishing development zones, reactivating the normal process of creating cities, and establishing and improving relevant policy systems. 展开更多

Purple soil is highly susceptible for overland flow and surface erosion, therefore understanding surface runoff and soil erosion processes in the purple soil region are important to mitigate flooding and erosion hazards. Slope angle is an important parameter that affects the magnitude of runoff and thus surface erosion in hilly landscapes or bare land area. However, the effect of slope on runoff generation remains unclear in many different soils including Chinese purple soil. The aim of this study was to investigate the relationship between different slope gradients and surface runoff for bare-fallow purple soil, using 5 m × 1.5 m experimental plots under natural rainfall conditions. Four experimental plots(10°, 16°, 20° and 26°) were established in theYanting Agro-ecological Experimental Station of Chinese Academy of Science in central Sichuan Basin. The plot was equipped with water storage tank to monitor water level change. Field monitoring from July 1 to October 31, 2012 observed 42 rainfall events which produced surface runoff from the experimental plots. These water level changes were converted to runoff. The representative eight rainfall events were selected for further analysis, the relationship between slope and runoff coefficient were determined using ANOVA, F-test, and z-score analysis. The results indicated a strong correlation between rainfall and runoff in cumulative amount basis. The mean value of the measured runoff coefficient for four experimental plots was around 0.1. However, no statistically significant relationship was found between slope and runoff coefficient. We reviewed the relationship between slope and runoff in many previous studiesand calculated z-score to compare with our experimental results. The results of z-score analysis indicated that both positive and negative effects of slope on runoff coefficient were obtained, however a moderate gradient(16°-20° in this study) could be a threshold of runoff generation for many different soils including the Chinese purple soil. 展开更多

Sea level anomalies observed by altimeter during the 1993-2006 period, thermosteric sea level anomalies estimated by using subsurface temperature data produced by Ishii and SODA reanalysis data, tide gauge records and HOAPS freshwater flux data were analyzed to investigate the long term sea level change and the water mass balance in the South China Sea, The altime- ter-observed sea level showed a rising rate of (3.5±0.9)mmyr-1 during the period 1993-2006, but this figure was considered to have been highly distorted by the relatively short time interval and the large inter-decadal variability, which apparently exists in both the thermosteric sea level and the observed sea level. Long term thermosteric sea level from 1945 to 2004 gave a rising rate of 0.15±0.06 mmyr-1. Tide gauge'data revealed this discrepancy and the regional distributions of the sea-level trends. Both the 'real' and the ther- mosteric sea level showed a good correspondence to ENSO: decreasing during El Nino years and increasing during La Nina years. Amplitude and phase differences between the 'real' sea level and the thermosteic sea level were substantially revealed on both sea- sonal and interannual time scales. As one of the possible factors, the freshwater flux might play an important role in balancing the water mass. 展开更多

Nitrate pollution in groundwater is a serious water quality problem that increases the risk of developing various cancers.Groundwater is the most important water resource and supports a population of 5 million in Anyang area of the southern part of the North China Plain. Determining the source of nitrate pollution is the challenge in hydrology area due to the complex processes of migration and transformation. A new method is presented to determine the source of nitrogen pollution by combining the composition characteristics of stable carbon isotope in dissolved organic carbon in groundwater. The source of groundwater nitrate is dominated by agricultural fertilizers, as well as manure and wastewater. Mineralization, nitrification and mixing processes occur in the groundwater recharge area, whereas the confined groundwater area is dominated by denitrification processes. 展开更多

On the basis of sufficient considerations to the attributes of China's development and uniqueness of population aging, this paper examines the overall impacts of China's population aging on labor supply in the four aspects of education level, skill level, work intensi(y and the share of working age population. Results indicate that despite the irreversibil#y in the decline of labor supply under the effect of intensifying degrees of population aging in the long run, this tendency will be weakened or slowed down by the improvement in labor quali^y. It is expected that China's real labor supply will not encounter a significant turning point by 2027, which is 12 years later than the occurrence of decline in nominal labor supply measured by labor quanti~ 展开更多

To analyze China’s actual urbanization level, we iden- tified two statistical approaches: using the population living within the administrative boundaries ("administrative-based" method) and within the urbanized or built-up areas ("infrastructure-based" method) of cities and towns as urban population. To illustrate the two approaches and the associated problems, we used data for Tangshan City as a case study. The estimates on the "administrative-based" method were unreliable and the "infrastructurebased" method provided a 29.4% urbanization rate for Tangshan City in 2002, which is lower than the mean of 36.1% for China as a whole published after the fifth national census in 2000. Given the city’s geographic location, comprehensive urban construction and economic development indicators, its urbanization rate should be higher than the average level. Thus, our results indicate that the value of 36.1% was higher than the actual status as a result of poor statistical quality and overestimation of the floating population. 展开更多

Based on the observations from 239 meteorological stations located in Central China (Henan, Hubei and Hunan provinces), this paper focuses on the climate change facts during 1961- 2010. There was a significant increasing trend in annual mean temperature for Central China during 1961 -2010. The increasing rate was 0.15℃ per decade, which was lower than the national trend. Since the mid-1980s, temperature increasing was obvious. Large increasing rate was observed in the mid-eastern part of Central China. For the four seasons, the increasing rate in winter was the largest (0.27℃ per decade). The increasing rate in the annual mean minimum temperature was larger than that in the annual mean maximum temperature from 1961 to 2010. As a result, the diurnal range of temperature decreased at the rate of -0.10℃ per decade. The extreme high temperature events were increasing while the extreme low temperature events were significantly decreasing. There was no obvious trend in annual precipitation for Central China during 1961-2010. Precipitation in summer and winter significantly increased; change of precipitation in spring was not obvious; precipitation in autumn was decreasing. The decreasing rate of annual rainy days was -3.4 d per decade. The precipitation intensity increased at the rate of 0.25 mm d-1 per decade. Heavy-rain days significantly increased. Spring and summer started earlier while autumn and winter started later. As a result, spring and summer duration was expanding whereas autumn and winter duration shortened. 展开更多

At present, part of the local government officials who like to do grandiose things to impress people blindly promote the development of the real estate, resulting in the gap with the population migration, so many ghost towns are born. In addition, while building the local infrastructure of some of the districts, they also ignore the problem of the rational allocation of their own financial funds.

This paper addresses the issue of Chinese students' oral English skills in talking about Chinese culture from the perspective of conversation analysis. To examine their performance in this regard, group discussion data in the classroom were collected for analysis. Their oral skills in talking about Chinese New Year and Christmas, a Western festival, were analyzed and compared to determine their oral performance in describing their native culture. Comments by two native English speakers on the students' performance are used to complement the conversation analysis. The results indicate that, compared with their performance regarding Christmas, the students were able to express a wider range of cultural connotations about Chinese New Year in English, but they used significantly fewer correct culturally-loaded words and phrases, and switched to Chinese much more frequently, suggesting unsatisfactory oral skills in describing Chinese culture. 展开更多

What is the highest stable urbanization level that China can reach? When can China complete its urbanization? To answer these questions, this paper presents a system dynamic(SD) model of Chinese urbanization, and its validity and simulation are justified by a stock-flow test and a sensitivity analysis using real data from 1998 to 2013. Setting the initial conditions of the simulation by referring to the real data of 2013, the multi-scenario analysis from 2013 to 2050 reveals that Chinese urbanization will reach a level higher than 70% in 2035 and then proceed to a slow urbanization stage regardless of the population policy and GDP growth rate settings; in 2050, Chinese urbanization levels will reach approximately 75%, which is a stable and equilibrium level for China. Thus, it can be argued that Chinese urbanization is a long social development process that will require approximately20 years to complete and that the ultimate urbanization level will be 75–80%, which means that in the distant future, 20–25% of China's population will still settle in rural regions of China. 展开更多

The North China Plain (NCP) is the most important food grain producing area in China and has suffered from serious water shortages. To capture variation water availability, it is necessary to have an analysis of changing trends in precipitation. This study, based on daily precipitation data from 47 representative stations in NCP records passed the homogeneity test, analyzed the trend and amplitude of variation in monthly, seasonal and annual precipitation, annual maximum continuous no-rain days, annual rain days, rainfall intensity, and rainfall extremes from 1960 to 2007, using the MannKendall (M-K) test and Sen's slope estimator. It was found that monthly precipitation in winter had a significant increasing trend in most parts, while monthly precipitation in July to September showed a decreasing trend in some parts of NCP. No significant changing trend was found for the annual, dry and wet season precipitation and rainfall extremes in the majority of NCP.A significant decreasing trend was detected for the maximum no-rain duration and annual rain days in the major part of NCP. It was concluded that the changing trend of precipitation in NCP had an apparent seasonal and regional pattern, i.e., precipitation showed an obvious increasing trend in winter, but a decreasing trend in the rainy season (July to September), and the changing trend was more apparent in the northern part than in the southern and middle parts. This implies that with global warming, seasonal variation of precipitation in NCP tends to decline with an increasing of precipitation in winter season, and a decreasing in rainy season, particularly in the sub-humid northern part. 展开更多

The spring water cycle is very im- portant to agriculture in planting crop and the initial growth of crop. Note that there was a significant abrupt decadal change in the water budget increase during early spring over eastern China in the late 1970s. Studied here are the decadal variations of water budgets over the key regions and the associated change of water cycle over East Asia and atmospheric circulation over Asia-West Pacific region in early spring, using the observed (OBS) precipitation, the ECMWF (ERA) and NCEP/NCAR rea- nalysis (NRA), and the Mantua's Pacific decadal oscillation index (PDOI). The water budget increments from March to April exhibited a sharp decrease over the key region around Huaihe River basin (HHR) (111°-120°E; 31°-36°N) after year 1978. Before 1977 the water vapor flux through south boundary of the HHR region increased greatly during March to April by 1.52 mm d^-1 in ERA and 1.88 mm d^-1 in NRA. Concurrently the moisture convergence and precipitation over the region also in- creased greatly. The increment for the moisture convergence was 1.11 mmd^-1 in ERA and 1.22 mm d^-1 in NRA, and for the precipitation was 1.05 mm d^-1 in observation and 1.05 mm d^-1 in ERA. April was the time that the water budgets over HHR increased most rapidly before 1977. But after 1978 the water budgets decreased conversely from Mach to April. The water vapor flux increment through the south boundary was -0.03 mmd^-1 in ERA and 0.01 mm d^-1 in NRA, the moisture conver- gence increment was -0.91 mm d^-1 in ERA and -0.53 mm d^-1 in NRA, and precipitation increment was -0.08 mm d^-1 in ob- servation and -0.15 mm d^-1 in ERA. Further investigation has shown that the large-scale atmospheric circulation in the early spring has correspondingly changed significantly after the late 1970s. During March to April, the weakening of the trough over East Asia became significantly slower, and the strengthening of the ridge over the west China became significantly faster in the middle troposphere after the late 1970s. At the same time, in the lower troposphere, the strengthening and northward extending of the west pan of the subtropical high and the weakening of the trough over the southwest part of the Aleutian low in the early spring became slower, and the weakening of the main part of Asian high became slower, but the strengthening of its west part became faster. This significant decadal change of circulation caused a sharp decrease in the northward extending speed of wa- ter vapor transport, and in the water budgets increasing speed over the southeastern China during early spring after the late 1970s. 展开更多
