The progenies with 38 chromosomes that were derived from the self-pollinated seeds of pentaploid hybrids (A^rA^nB^cC^cC^n) were used for further research. Some of the partial new-typed B. napus showed normal meiotic behavior, high portion of germinated pollen and normal embryological development. This indicates that the selected new-typed B. napus had a balanced genetic base. Molecular analysis showed that about 50% of the genome in the new-typed B. napus was replaced by A^r and C^c subgenome from B. rapa and B. carinata. Considering the genetic diversity among different lines of new-typed B. napus, it was deduced that the introgression of the genomic components from B, rapa and B. carinata could widen the genetic diversity of rapeseed.展开更多

This study uses survey data from rural migration laborers across the eastern, central, and western China to construct a comprehensive labor migration stability index, and compares the determinants of the migration stability of rural labor among cities and industries using Geodetector. The results are as follows: 1) Compared with the midwestern cities, eastern cities have attracted younger and more skilled rural labor, and industries with higher technical content have higher migration stability among rural laborers. 2) Rural laborers more often adapt to changes by changing employment instead of changing working-cities. 3) The individual experiences of rural laborers and urban characteristics have significant impacts on the stability of migration, and family and societal guanxi(Chinese interpersonal relationships) enhance migration stability. 4) A unified labor market and convenient transportation have somewhat slowed industrial transfers and labor backflow. This study enhances our understanding of the roles of industrial transfer and new-type urbanization in shaping the labor geography landscape and provides policy implications for the promotion of people-oriented urbanization.展开更多

From detailed geochemical and U-series chronological studies, analysis of major and minor elements performed by X-ray fluorescence spectrometry (XRF) and inductively coupled plasma-mass spectrometer (ICPMS), three major accretion periods and corresponding paleocnvironments can be ascertained. The first period is a faster accretion period in the terminal Late Miocene to the Early Pliocene with looser structure and higher volcanic detritus content, corresponding to the active Antarctic bottom waters and depressed temperature from the intermediate Middle Miocene to the Early Pliocene. The second period is a pulse of pelagic clay deposition at the Early to Middle Pliocene, reflecting the shrinkage of the Antarctic bottom waters and the global temperature elevation of this period. The third period is a slower accretion period from the Middle Pliocene, which indicates the more violent activity of Antarctic bottom waters once again and more depressed temperature than the first period, facilitating the accretion of a more compact and pure ferromanganese zone. The paleoceanographic histories of these studied areas had not been made clear in previous research.展开更多

The UEC-SD model is applied to analyse the effect of the ar- banisation process on the regional energy structure and CO2 emissions, followed by simulation of future production and living energy consumption structure as well as the evolutionary trend of CO2 emissions of three urbanisation scenarios (low speed, intermediate speed and high speed) under the assumed boundary conditions in urban and rural areas of Liaoning Province, China. The results show that the urbanisation process can alter production and the living energy consumption structure and thereby change regional CO2 emissions. An increase in the urbanisation rate in case area will lead to regional COz emissions rising in the short term, but when the urbanisation rate approaches 80%, CO2 emissions will reach a peak value and then decrease. Comparison of different urbanisation rates showed that pro- duction and living energy consumption exhibit different directions of change and rules in urban and rural areas. The effect of urbanisa- tion on CO2 emissions and energy structure is not direct, and urbanisation can increase the differences in energy and CO2 emissions between urban and rural areas caused by the industrial structure, technical level and other factors.展开更多

Based on the land-use change data, this paper analyzes the characteristics of land use change and its driving factors in Guiyang with the method of land-use dynamic analysis, land utilization and factor correlation analysis. We get the following results:(1) the change of land use was obvious during 2004 and 2012. The area of arable land and other land were decreased, the rate of decrease are 3.89% and 8.24%. In the meantime, a series of construction land and forest area increased a lot, the rate of increase are 3.89% and 8.24%.(2) The integrated land use dynamic degree of two research stages(2004-2009 and 2009-2012) were decreased from 2.12% to 0.34%, this suggests dynamic changes of land tend to be stable.(3) Four kinds of Land use class have a great contribution to the index of land use degree respectively. The composite index of land use degree rose from 229.58 to 247.19 during 2004 and 2012; the land use is still in the development stage.(4) Economy, population, transportation and policy guidance are the main drivers of land use change.展开更多

The recent developmental urban processes have been considered through three groups of indicators: demographic, regional and socio-geographic development. Based on results of the surveys conducted in the regional economic centres in Bosnia and Herzegovina in 2011, a development of urban functions in the urban centres has been shown. It has been proved that the dominant tertiary activities have a big importance and an intensive influence on urban and economic development in all urban settlements. The research included a theoretical part within which the literature on urban and economic development of settlements has been searched. For needs of the research, eight economic centres in Bosnia and Herzegovina were chosen. Analysis of the obtained results shows a different level of urbanisation in Bosnia and Herzegovina with particularly separated larger and asymmetrically distributed urban centres: Sarajevo, Tuzla, Mostar, Banja Luka, Zenica, and Biha6. The mentioned urban and economic centres are distributed along the major traffic communications. The settlements in east and west part of Bosnia and Herzegovina, in which a traffic network is poorly developed, have a lower urbanisation level. The obtained data proved the existence of a traditional difference and a different level in development of particular regions and total economy in Bosnia and Herzegovina. Low urbanisation level of a large number of settlements in Bosnia and Herzegovina, is in direct connection with economic development and density of those settlements. The achieved urbanisation level with an overall economic development is characteristic of Bosnia and Herzegovina and of the other countries in its surroundings as well.展开更多

The airtemperature of blast furnaces can be reached to 1250-1300℃ by burning single blast furnace coal gasif high speed burner is applied to blast furnaces and new-type external combustion swirl-flowinghot stove is used to preheat their combustion-supporting air. The computational results of the flowand heat transfer processions in the hot stove prove that the surface of the bed of the thermalstorage balls there have not eccentric flow and the flow field and temperature field distribution iseven. The computational results of the blast temperature distribution are similar to thosedetermination experiment data. The numerical results also provide references for developing anddesigning the new-type external combustion swirl-flowing hot stoves.展开更多

An increase in the urbanisation rate in case area will lead to regional COz emissions rising in the short term, but when the urbanisation rate approaches 80%, CO2 emissions will reach a peak value and then decrease. Comparison of different urbanisation rates showed that pro- duction and living energy consumption exhibit different directions of change and rules in urban and rural areas. The effect of urbanisa- tion on CO2 emissions and energy structure is not direct, and urbanisation can increase the differences in energy and CO2 emissions between urban and rural areas caused by the industrial structure, technical level and other factors.

文摘Based on the panel data(2005-2019)of cities(prefectures)in the Chengdu-Chongqing Economic Circle,we have developed an evaluation system for agricultural modernization and new-type urbanization that measures the development level of each city and applies the coupling and coordination model to calculate their coupling and combination levels.The results indicate that the level of comprehensive order parameters of agricultural modernization in various cities(prefectures)in the Chengdu-Chongqing Economic Circle generally displays an upward trend.The areas with high-degree agricultural modernization were mainly distributed in Chengdu from 2005 to 2010,and the center of agricultural modernization was shifted to western areas after 2010,with a stable upward trend in the level of comprehensive order parameters of new-type urbanization.In terms of coupling degree,there was an overall upward trend.Except for Nanchong and Dazhou,other cities(prefectures)progressed from“Undeveloped Coordination”to“Intermediate Coordination.”The imbalanced development of agricultural modernization and new-type urbanization continually improved,with the combination level increasing from“Low-Low”to“Medium-Medium.”
文摘正Distinguished guests, ladies and gentlemen, dear friends: Today we meet here in picturesque Hangzhou for the 2012 Understanding and Cooperation Dialogue Part II: New-type Community and Harmonious Society. On behalf of the National Committee
文摘Various postulations on the relationship between urban morphology and air quality are qualitative.This fails to establish the strength of the contributions of each morphological parameter in the spatial distribution of the air quality.It is this gap in knowledge that this study sought to fill by modelling the correlation existing between the urban morphological variables of development density,land uses,biomass index and air quality values of Nairobi city.While 30 development zones of the city constituted the target population,IKONOS satellite imagery of the city for the year 2015 was utilised in establishing the development densities,land uses and biomass index.The parameters were transformed into numerical surrogates ranging from 1 to 10 with lower values accorded to zones with low biomass index,the highest development density,noxious land uses,high gaseous concentrations and vice-versa.Pearson’s correlation coefficients(r),coefficients of determination(R),t-tests and the Analysis of Variance(F-tests)with levels of significance being 95%were used to determine the strengths,significances and consistencies of the established relationships.The study established that development density is the most significant morphological variable influencing the distribution of air quality.This is followed by biomass index and to a weaker extent,land uses.
文摘Shi Lianzhen, a 79-year-old villager from rural Beijing, has been suffering from coronary heart disease and myocardial irffarction. On October 15, 2003, she unexpectedly received 10,064 yuan (US$1,215) in subsidies for her diseases from the local government department in charge of rural co-operative medical care. This old female farmer, without any income source, was so excited that she couldn’t put her feeling into words. For the first time in their life, Chinese farmers can enjoy medical care insurance like those wage workers in dries, when their health fails them and their lives are in the menace of death.
