Abstract: Regulating the modes of production and living of urban residents in China is an important measure to cope with environmental changes, and the primary premise is to greatly improve the environmental awareness of urban residents. At present, research on resident’s environmental awareness has been carried out in many cities in China. Nevertheless, little comparative research has been carried out among cities, and there is lack of research on mutual relation and cooperation inside natural regions and the intrinsic relation in adaptability to environment. Therefore, taken the papers collected in CNKI as the data source, the paper has selected the cities in the eastern, central and western region as the objects to in-depth analysis of the present situations and the intrinsic relations between the level of environmental awareness and the adaptability to environment of the urban residents in 3 regions so as to provide reference for the government to formulate relevant management policies. As shown in the research results, the residents in the eastern cities of China have the highest overall level of environmental awareness, followed by the western cities, while that of the central cities is the lowest. In addition, the overall levels in the 3 regions differ greatly from each other. There is certain correlation between the 3 aspects of environmental awareness and 6 factors of adaptability to environmental changes. For example, Lanzhou and Inner Mongolia have the relatively lower environmental awareness with a larger population, which causes the low overall level of their environmental awareness. The educational level and energy-saving and emission-reduction level of Inner Mongolia, Jiaozuo and Suqian are relatively lower with relatively better environmental conditions, leading to relatively lower level of environmental knowledge. Urumchi and Inner Mongolia have a relatively larger population and lower economic level, which cause lower environmental awareness. The public awareness and environmental situations of Jiaozuo and Suqian are relatively better, and therefore the environmental protection there is more desirable. The fact that Shanghai has the highest education is the main reason for the highest comprehensive capacity.

Abstract: The Chaohu Lake Basin is one of the human influenced regions of the Pre-Qin Period in China, and more than 100 archaeological sites of Pre-Qin Period were found in this area. There are good relationships between temporal-spatial distribution of archaeological sites and environmental changes, especially with the changes of lakeshore of Chaohu Lake caused by the regional climatic oscillation. The relatively warm and humid climate of the Pre-Qin Period, the important position of ancient Chinese culture exchanges between the north and south, the developed water network, and rich biological resources, all of these factors had been the important environmental foundation for the originating and development of the Pre-Qin culture in the basin.

Abstract: The dust storm is a kind of disaster weather with serious harmfulness. April 16~17, 2006 Beijing dust storm samples were collected far away from the highway. The processes of dust storm and materials of dust storm give us an opportunity to better understand the accumulation of loess and environmental influence of mankind to the desertification in arid to semiarid areas. We collected the dust storm samples, and carried out initial measurement using the luminescence research. Through the raw samples luminescence curve, the intensity of IRSL was very low. A number of tests were undertaken on quartz extracted from the sample prior to routine application protocol. From these results, we know that the equivalent dose and thermal transfer is sensitive to the rising preheat temperature. While De is unsensitive to the cutheat temperature (except for 280 °C). We chose a preheat temperature of 200 °C 10s and a cut heat of 160 °C in these tests. The results showed that the curve of equivalent dose for this dust storm had several peaks. It is a new evidence to prove that the dust source maybe originate from several regions.

Abstract: Based on amount change and distribution density of the Neolithic sites in Henan Province, these sites are divided into three types: (1)the Growth type. This type is mainly located in Luoyang Basin where the landform was convenient for millet-farming and settlement-clustering. (2) the Atrophy type. It mainly sits in the Nanyang Basin in which was a transition zone for cultural exchange. And (3) is the Oscillation type. This type distributes around the area of Yinghe-Ruhe River downstream with low land and frequent floods, which affected the amounts of sites in respond to series climate fluctuations in the early and middle Holocene. Comparatively, the unique terrain environment and water networks in the Luoyang Basin heralded the earliest civilized fruit in China and to be the cradle of early cultural transmission.

Abstract: Taking Lop Nor as a study case, the paper not only systematically discusses the dating of the Tamarix cone, the methods and technical routes to extract its climatic environmental information, but also interprets the environmental change in Lop Nor region in the past about one hundred and sixty years, which provides a new theoretical basis and technical reference for building the high-resolution environmental sequence in the relevant area.

Abstract: This paper studies on the formation mechanism of how organizational innovation is established and developed. We built a model including envirnomental change, organizational learning and organizational innovation. Using the empirical study as a sample of 194 enterprises the results of this paper show that (1) the external environment factors have no direct effent on organizational innovation. The main factor of organizational innovation driven is organizational learning. (2) the industry of environmental change on the organizational learning have a significant impact to organizational learning and changes in the macroeconomic environment had no significant effect to organizational learning.
