The results showed that the natural wetland and agricultural land tended to decrease, while the saltern, maricultural areas and construction land increased apparently. The overall landscape shape tended to develop in simplification and regulation and with the development of population and social economy, human’s intervention to the landscape was getting improved.展开更多

And planners realized that a safe city is very important for sustainable development. Traditional urban public safety planning begins to perfect the contents and method. And regional research is an important aspect in the improvement of new era urban public safety planning. This paper chooses Tianjin, the important city in Bohai rim area as the example for research. Tianjin urban public safety planning includes not only comprehensive disaster prevention and reduction, effectively preventing and reducing disasters, ensuring the safety of the life and property of the residents, but also sharing resources and facilities from the view of megalopolis, eliminating hidden area troubles, reducing whole environment risks and so on.展开更多

The legacies of these two political and historical landscapes have had a hand in shaping and disfiguring the nascent governments that would be born in Africa with vanguard parties not tolerating opposition. In a bid to stay in leading positions, as founding fathers of revolution, incumbent governments have used different tools, some very unorthodox, from brute force, genocides, governments of national unity and violent elections to stay in power and destroy opposition. This paper seeks to trace how Zimbabwe has fared in establishing a democratic government from Lancaster to the 2013 March referendum. Zimbabwe, following a Lancaster House Agreement C1979）, like Kenya （1960）, held elections in 1980, making R. G. Mugabe the first black Prime Minister and C. Banana the President. Some scholars have argued that the 1980 elections have been the only free and fair elections in Zimbabwe＇s history of elections. To measure the level of democracy in Zimbabwe, the paper shall highlight the euphoria at 1980, read through gukurahundi of 1983, the unity accord of 1987, select parliamentary and presidential elections, the fast track land reform of 2002, the 2009 Government of National Unity as well as the 2013 constitution amendment. The study shall largely make use of desktop and interviews of ordinary Zimbabweans, politicians, and students in universities with regards to matters of governance. The paper concludes that post communist governments have struggled to establish democracy.展开更多
