Xu Wei was a painter with a spirit of the reform and innovation in the late Ming Dynasty, and his painting style pioneered the precedent of the Chinese freehand bmshwork. In his creation of the paintings and the painting theories, he gave the innovative development to the theories of the traditional Chinese paintings and the freehand brushwork in this period in our country, and also promoted the further formation of the freehand flower and bird painting styles. Xu Wei＇s t^eehand flowers and birds combined the strengths of each school, and in the painting style, he was bold and unconstrained, and the pen and ink was coherent, and the form and the spirit were assistant and bleeding. The pen and ink all embodied the wonderful skill of the Chinese traditional paintings, and boldly integrated the wild cursive of the calligraphy in the paintings. This approach was the innovation of the techniques of the Chinese traditional paintings and the promotion of the thinking. The author of this article will begin the research on the relevant contents of the artistic achievements and the influences of the freehand flower and bird paintings by Xu Wei.展开更多

Unbalanced regional development, appearance of super megacities and concomitant problems,and conflicts between urbanization and cultivated land protection are three critical problems that Chinese urbanization has to face. To develop new plans for foreseeable future urbanization in China, it is critical to understand the evolving history of cities across China. This study maps urban expansion of 60 typical Chinese cities based on large amount of remote sensing data and the labor-intensive image interpretation method, in order to understand the history of urban expansion from the 1970 s to 2013.Results showed that area of cities expanded 5.23 times compared to their area in the 1970 s. Urban expansion in China accelerated three times(1988–1996, 1999–2006, and 2009–2011) and decelerated three times(1997–1998, 2007–2008, and 2012–2013) over the 40 years. The urban area of South China expanded most significantly 9.42 times, while the urban area in Northeast China expanded only 2.37 times. The disparity among different administrative ranks of cities was even greater than(3.81 times) the differences among different regions. Super megacities have been continuously expanding at a fast rate(8.60-fold), and have not shown obvious signs of slowing down. The proportion of cultivated land among the land sources for urban expansion decreased to a small extent in the 1990 s, but cultivated land continues to be the major land source for urban expansion. Effective future urbanization needs controlling the expansion scale of large cities and reasonably developing medium and small cities, as well as balancing regional development.展开更多
