西藏江孜县农村能源结构优化研究

The Optimization of Structural schemes of Rural Energies in Jiangzi County in Tibet

１９９４年江孜县农村生活能源短缺２２．８６％。尽管购入牛粪和薪柴等生物质能源３９７０ｔ，林地过伐１９．１６％，但仍不能满足人民的基本生活用能需求。通过农村能源结构调整和生产、能源技术的持续开发，至２０１０年，生物质能勿需购进，畜粪焚烧率由目前的９０％降至３５％，农村能源自给有余，粮食商品率由目前的２０％左右提高到３８％，农业经济效益大大提高，江孜农业将在良性运转的基础上持续高效地发展。

There was a shortage of 22. 86%of daily-use energies in Jiangzi Countyin 1994.Although there were an import of biomass energy(cow dung and firewood)of3970 tons and a firewood of 19. 16%overcut from the woodlands,the basic requirementfor daily-use energies could not be met with.Through the adjustment of rural energystructural schemes,and the sustained development of energy technologies,the biomassfuels will no longer be imported and the cow dung to be used directly as fuels will be de-creased from 90%of the total at present to 35%by the year 2010.By that time,rural en-ergy resources will be self reliant with some:urplus.The food commodity rate wlll beraised ftom the present 20%to 38%Agroeconomic returns will be greatly raised.Agricultural prod uction in Jiangzi County in Tibet will develop at the highly effectiverate on the basis of good circulation.
