The Study Of Sustainable Development For Small Hydropower Replacing Firewood Unit Based On Eco-Economic Model

The project of small hydropower replacing firewood for ecology protection is a public interests project that consolidate the achievement of returning land for farming to forestry, and improving the farmer quality of life. Thus, developing the study of small hydropower replacing firewood for ecology protection project has great science value and practical significance. This thesis adopts technical route of combining theoretical research with instance application, and studies small hydropower replacing firewood for ecology protection project which mainly based on the ecological footprint method and energy theory, meanwhile carries Green calculation to this project using Green GDP Accounting System, also the study of sustainable development is made to small hydropower replacing firewood for ecology protection project in Lingchuan County, Shanxi Province. The main contributions in this dissertation are as follows:(1) Ecological capacity models were improved, ecological footprint,ecological capacity and ecological deficit of small hydropower freplacing firewood unit are dynamic analyzed, and sustainable development evaluation indexes of ecological footprint pressure index,ecological occupancy index and ecological economic coordination index are set up, moreover, ecological footprint and ecological capacity of region carried on small hydropower for fuel ecology in Lingchuan County are forecasted using GM (1, 1) model. Case study is carried on to small hydropower for fuel project in Lingchuan County. The results showed that energy land makes the greatest percentage in the six models of ecological productive areas; The effect of local ecological environment improvement is obvious, Ecological capacity has increased obviously, and local ecological deficit measure is reduced. Therefore, bringing small hydropower replacing firewood for ecology protection project into effect plays a positive role to local sustainable development in remote mountain area. (2) Sustainable evaluation study is carried on to small hydropower replacing firewood for ecology protection item with emergy analysis theory. Based on practical investigation to project area, research object can be divided into two sub-systems: ecology station construction sub-system and emergy sub-system ,and set up evaluation index respectively. Comprehensive evaluation index system is set up according to the characteristics of small hydropower replacing firewood for ecology protection project. Practical calculation has been made to the Magedang project unit in Ling chuan County, and the results shows that the sustainable development index of ecology station construction sub-system is 1.51, sustainable development index of emergy sub-system increased 4.21 from 2.34 after the item has been put in practice, so the implement of this project has played a promoting role in local sustainable development.(3) This article has discussed Green GDP Calculation of small hydropower replacing firewood for unit and set up accounts for small hydropower replacing firewood unit. Green GDP value is educed though the accounting to traditional GDP value calculation,ecology Service Value calculation,ecological power output value calculation and ecological environmental costs. Practical calculation has been made to the Magedang project area in Ling chuan County, and the results shows that Green GDP increased obviously after the item has been put into practice in small hydropower replacing firewood unit, and the amplitude of per capita income in construction period is more than production period , meanwhile it can lead the development of economy in a long time.
