Effect Study On Sustainable Development Of Watershed From Hydropower Development

Our country is affluent in water resources and has a natural advantage in hydropower development. Hydropower development in China has made brilliant achievements since reform and opening up. Both in installed capacity and annual amount of power generation increase steadily every year. Hydropower development is the only renewable clean energy that human can commercial development and utilization in large-scale. As the rapid development in economic and improvement in people's livelihood in china, degree of dependence on electric power is becoming more and more serious. Therefore, accelerating the development of hydropower is not only conducive to improving the structure of power industry in china, but also be able to effectively support the development of economy and society.Analysis from the energy composition of the international developed countries, China's hydropower development rate is remaining with the lower level. But the prospect of China's hydropower development is bright. Despite many difficulties setbacks encountered in the development process, but China's hydropower is still developed tenaciously, from weak to strong, from small to large. It has gone through four stages of development, the technical constraints, investment constraints, market constraints and the ecological constraints. Currently, some environmental organizations and experts believe that hydropower development cut off rivers, inundated land, migration of population. It will inevitably have a negative impact on environment. Particularly the impact on the ecological environment has attracted great attention of people. Public opinion also has given great attention on itHydropower development as complicated systems engineering, in the process of hydropower development must be researched in accordance with the requirements of systems engineering. It is necessary not only to take a leading role in the macro, but also take into account the micro-factors. Scientific development planning, design, and construction is the basis to achieve sustainable development of river basin. Valley as a relatively complete ecological and geographical unit has a unique natural and geographical condition, and a unique development model, and unique cultural traditions, and unique slight of entironment. Therefore, the implementation of sustainable development in the unit of river basin, not only reflects the important role of the sustainable development of basin circle to the sustainable development, but also, more importantly, to explore the mutual relations of sustainable development and population, resources, environment and development.The effect of hydropower development on sustainable development of river basin mainly behaved in the impact on the development of economic, improvement of social and environmental quality. it is undeniable that hydropower development will greatly accelerate the development of river basin economy, improvement of social and environmental quality. But the development of disordered brings extremely serious consequences, mainly in the migration and the ecological crisis. In addition, hydropower development has a huge impact on culture river basin, and even more it is difficult to recover. Under the present conditions of our country, although faced with many problems, hydropower development would continue for a long time. Therefore, in hydropower development process we must take effective measures, meet the river basin requirements of sustainable development in the maximum likelihood, implement the harmonious development of hydropower.
