Until recently such biotic energy source still constitutes more than 92 per cent of total rural energy consumption due to lack of petroleum, coal and new alternative energy sources. As a result, environmental degradation such as land desertification, soil erosion, grassland degradation and soil fertility reduction is increasingly aggravated, the area of desertified land has increased 1467.5 km2 from 1991 to 1997. Degraded area of grassland has reached 2.60×107hm2, increased by 116.1% from 1987 to 1996. To prevent further deterioration of eco-environment in Tibet great efforts should be made to make full use of ample solar energy, wind energy and other biotic energy of the Qinghai-Tibet Plateau. The solar cooking stoves and solar hothouse, expand forest area and replace existing abiotic energy sources with firewood forest should be popularized. This is an urgent task to protect the eco-environment of Tibet today.展开更多

The implementing objectives and processing program of Scottish policy were respectively set forth,including 6 steps of statement of Intent, proposal, assessment, contract signing, claims and inspections, breaches and penalties.Therein 3 meaningful aspects for the construction of current compensation mechanism in China were as following: keeping consistency between national and local policies to establish close connection in eco-goal and funding subsidy, setting both improved assessment procedure and scientific compensation system to promote the lasting implementation of environmental-friendly measures, making correspondent check and monitor mechanism together with breach and penalty mechanism to secure the payment execution.展开更多
