The Korean Peninsula, adjacent to China, plays an important role in the international environment of Northeast Asia. The Korean Peninsula includes South Korea and North Korea—two countries that have a great difference in their institutions and economic developments. Therefore, we aim to quantify the spatiotemporal changes of croplands in these two countries using Landsat Thematic Imager(TM) and Operational Land Imager(OLI) imagery, and to compare the differences of cropland changes between the two countries. This paper take full advantage of ODM approach(object-oriented segmentation and decision-tree classification based on multi-season imageries) to obtain the distribution of croplands in 1990 and 2015. Results showed that the overall classification accuracy of cropland data is 91.10% in 1990 and 92.52% in 2015. The croplands were mainly distributed in areas with slopes that were less than 8° and with elevations that were less than 300 m in the Korean Peninsula. However, in other region(slope > 8° or elevation > 300 m), the area and proportion of North Korea's croplands were significantly higher than that of South Korea. Croplands significantly increased by 15.02% in North Korea from 1990 to 2015. In contrast, croplands in South Korea slightly decreased by 1.32%. During the 25 years, policy shift, economic development, population growth, and urban sprawl played primary roles for cropland changes. Additionally, the regional differences of cropland changes were mainly due to different agriculture policies implemented by different countries. The achievements of this study can provide scientific guidance for the protection and sustainability of land resources.展开更多

It should be considered on two important points about the history of modernization of Republican Turkey. The first of these is mentalities and ideological attitudes of modernizing elites. The emphasis to be made is to actually point to an opposition： Republican bureaucracy, in other words, the Kemalist elites, believed that progress in the sense understood by the French revolutionaries, positivist ideas, and secular point of view, on the other hand refused to tradition, namely Ottoman-lslamic past/background. Secondly, the Kemalist bureaucracy followed a specific application of the statist economic strategy. The state on the one hand has made investments using its own resources on heavy industry, established monopoly on certain products, on the other hand has followed liberal policies in order to create a national bourgeoisie. In addition, it cannot resolve/transform land ownership regime in favor of landless peasants. The turning point in the economic development of Korea was the military government of Park Chong Hee. The main policy during the 20 years of government was self-sufficient national economy. A presidential central industrial planning board （EPC） was responsible for the planning of all new investment areas and provided policy coordination among related ministries. Government could control the allocation of all financial resources through nationalized commercial banks. Economic planning by government included resource allocation, setting export targets for big family holdings, selective support of strategic industries, and successful private companies. So, government played an important role in the accumulation of capital in the hands of selected loyal new bourgeoisie class, big family holdings （chaebols）, which helped the succession of national development projects. The government used nationalism and moderated Confucius values as a means of creating developmental spirit. Anti-industrial teachings in Confucianism has been changed by Western values to form a new development-oriented work ethics, but core teachings like paternalism, hierarchical order in groups, emphasis on education, harmony, collectivism were strengthened by national education. Government policies and modified cultural elements caused an able and willing labor force and committed nation for overcoming poverty, strengthening Korea＇s economic position in the region.展开更多
