In this study, coal fire temperature is retrieved based on Landsat 5 TM images and Generalized Single-Channel Algorithm (GSCA), in Wuda coalfield, Inner Mongolia, China. Then coal fire zones are extracted by Jenks′ natural breaks and threshold methods based on temperature images. Changes of coal fire zones are analyzed from 1989 to 2008. The results are summarized as follows: 1) The coal fire temperature retrieval method based on Landsat 5 TM and the GSCA model is effective and feasible, because the temperature error is relatively small (from –2.9℃ to +2.6℃) between the measured temperature and the retrieved temperature. 2) The accuracy is relatively high to extract coal fire zones through the Jenks′ natural breaks and threshold methods, because 83.56% of surveyed area is located in the coal fire zones extracted in 2005. 3) The coal fire area increased 9.81 × 10 5 m 2 from 1989 to 2005, and the annual growth is about 6.1 × 10 4 m 2 , with an annual increasing rate of 2.48%. The area of coal fire decreased by 8.1 × 10 5 m 2 from 2005 to 2008.展开更多

How to conduct moral education to help the students shape good moral norm is an issue frequently discussed in the academic area. This paper probes into this issue from the formation of incorrect outlooks towards wealth and power, discusses the risks of apparently incorrect moral education, and suggests the right moral education ways, combined with some specific cases: return to the true state of morality in the concept of moralization; conduct the students' sense of value through teaching activities in the content of moralization; and of moralization. distinguish between good and evil in moral conflict in the way展开更多

Gender issues in the formation of selfhood and philosophical concepts of behavioural "performativity" will be examined in the context of China's experimentations in projecting new concepts of womanhood and the female self. As a context, I will also outline some of the changes in cultural values and ethical categories in China over the past century, so as to see why the individualist conception of the self has played such a paramount important role in China's quest for modernity.展开更多

To respond it, we construct a village-level multidimensional poverty measuring model, and use indicator contribution degree indices and linear regression method to explore poverty factors, while adopting Least Square Error(LSE) model and spatial econometric analysis model to identify the villages' poverty types and poverty difference. The case study shows that:(1) Spatially, there is obvious territoriality in the distribution of poverty-stricken villages, and the poverty-stricken villages are concentrated in contiguous poverty-stricken areas. The areas with the highest VPI, in a descending order, are Gansu, Yunnan, Guizhou, Guangxi, Hunan, Qinghai, Sichuan, and Xinjiang.(2) The main factors contributing to the poverty of poverty-stricken villages in rural China include road construction, terrain type, frequency of natural disasters, per capita net income, labor force ratio, and cultural quality of labor force. The main causes of poverty include underdeveloped road construction conditions, frequent natural disasters, low level of income, and labor conditions.(3) Chinese poverty-stricken villages include six main subtypes, and most poverty-stricken villages are affected by multiple poverty-forming factors, reflected by a relatively high proportion of the three-factor dominant type, four-factor coordinative type, and five-factor combinative type.(4) There exist significant poverty differences in terms of geographical location and policy support, and the governments still need to carry out targeted poverty alleviation measures according to local conditions. The research can not only draw a macro overall poverty-reduction outline of impoverished villages in China, but also depict the specific poverty characteristics of each village, helping the government departments of pov-erty alleviation at all levels to mobilize all kinds of anti-poverty resources.展开更多

The earliest record of the debate between Legalism and Confucianism serves as the ground for us to examine the necessity of morality in the practice of law, while the introduction of Confucian ideals into law since the Han dynasty opened up the process of coalescing morality with law in imperial China. Through the case study of xiao (filial piety ), the article argues that the Confucianisation of law took a long time to complete.展开更多
