Urban sustainable development opportunities and challenges for the United Nations international ecological safety Academy of Kung skillfully jade 2000 years in the United Nations Millennium Declaration, establish a set of urban development of guidelines and goals. Articles 1, 7, 8, and ecological security for the 2002 World Summit on sustainable development was included in the six main development focus: water and sanitation, appropriate housing, energy, medical, food, and biological diversity. The requirements of ecological safety. Ecological safety of six important part: 1. non-traditional security mainly include natural disasters, sudden onset of ecological disaster, labor safety, responsibility for safety, food security, such as infectious disease epidemics. 2. environmental safety mainly include global warming, CO2 emissions, water scarcity and pollution, desertification, air pollution, marine pollution, harmful pollution of the environment, rising sea levels caused rockfalls, red tide, the ozone layer destruction, etc. 3. species security mainly include forest vegetation damage, loss of biological diversity, alien species invasions, transgenic technology and products. 4. the safety cultural heritage mainly includes historical and cultural heritage, intangible heritage, natural and cultural heritage, security, etc. 5. nuclear safety, radiation , chemical and biological weapons mainly include military nuclear safety and nuclear security part of the name. Radiation including chemical radiation, optical radiation, the electronic disclosure of radiation, chemical and biological weapons. 6. sustainable development mainly include the sustainable economic development, social sustainability, eco-sustainable development. Ecological safety of three basic features: 1. natural disasters and emergencies of ecological disasters, can weaken a country's economic support capabilities. For example, in January 2008, 10-28, China Southern and snow disaster has occurred, this actually is a burst of ecological disaster, the disaster caused 14 provinces 7786.2 million people affected by disasters in direct economic losses 400 billion. 2. natural disasters and sudden catastrophe can produce a lot of refugees, the raises local instability and vulnerability to social instability. For example, 2008 Wenchuan earthquake "5.12" mega, affected over 45 million people, five million people homeless, families of the injured person 68170 374159 missing 17426. Whether direct or indirect economic losses were heavy economic losses. After the earthquake, the Chinese people, it is certain to tide over the tragic scenes, moved to the world. The international community to fully affirmed the Chinese Government in Imposts before responding well, disaster relief, orderly, and efficient, positive evaluation of the Chinese Government depending on people's lives and above all else, overcome difficulties and rebuild their homes, placement of victims in the strong measures that effectively prevent social unrest and instability. 3. natural and ecological disasters can be on a State and neighboring countries or even global impact and influence, easy, and even diplomatic dispute between local wars. For example: 2004 took place in China Jilin petrochemical plant explosion, the disaster that the formation of the Songhua River watershed pollution, Harbin, jiamusi, Riverside cities have four days without water, direct economic loss of 70 billion yuan, and the flow of the Songhua River is Russia. Wenchuan earthquake is well-known century catastrophe! again such as occurring in the Darfur region of the dispute, but the sudden moments of ecological disaster is the result of human and economic losses than a local wars. We know that the sustainable development of the urbanization is the international community in the 21st century's most pressing challenges, the city as an economic and social development of the engine, to create wealth and opportunity, but do not get good planning, management will also give us a disease, crime, pollution and poverty. 2050, the world's population will be close to 90 million, of which two-thirds will live in urban areas, how to manage the implementation of sustainable urban development in developing countries and developed countries, one of the major challenges facing. At present in water and sanitation challenges we face in developing countries over a billion people lack safe drinking water. According to statistics, world, daily 14000 �� 30000 in water-related diseases, most of whom are elderly and children. I was learning the Hydrogeology of a pressing duty and obligation, therefore I want global hydrology and climate, the environment, soil, agricultural experts work together to use their learned expertise to develop a series of effective, long-term development of the rules dealing with the rapid development of the city of climate change, energy and environment, as the United Nations Millennium goals, to make due contributions.
