An Analysis Of Economic Benefit Of Nanmulin County To Forestland Tibet

The purpose and emphasis of this project is to improve the ecological environment and reduce the natural disaster,then gain the sustainable development of human and the environment.In 2002, the project of turning farmland into forest was put into effect in the district of Changdu(as an experimental unit) in Tibet.In 2003 this project was implemented in the whole Tibet.The benefit of the project is the very important thing for us farmers and herdsmen.Therefore, the analysis to the ecological benefit of turning farmland into forest project is of great importance.Through the questionnaire to farmers and with the method of benefit survey,this article choose to survey Nanmulin town in Tibet Autonomous Region to analysis the ecological benefit of turning farmland into forest project. The paper establishes evaluation index system, use of effective monitoring of the basic method of converting cultivated land into forests and the access to a large number of documents and field surveys the region to analyze effectives on the guide of theory of public goods and economic growth theory. What's more, and theory of sustainable development put forward to proposals for sustainable development in Tibet according to the principle to sustainable development.Firstly, the paper designs the principles according to the established evaluation index and system ,draws on existing research results and use method of theoretical analysis and field survey methods to establish the ecological, economic and social evaluation index system; Secondly, according to the established evaluation index, use shadow project and statistical analysis (paired data test of significance, regression analysis, pros and cons method) to evaluate the three effectives about project of converting cultivated land into forests in South Mullin county. Finally, proposed the corresponding recommendations based on the above research.The benefit of ecology: After the process of return land to forest,the cover of forest was recovered and the rate of plant cover was increased.The rate of plant cover in Nanmulin town increased from 8.69% in 2002 to 8.98% in 2010.The value of water protection is 1,335,430,000RMB;The value of purify the environment is 626,430,000RMB;The amount of oxygen in Nanmulin town increased.In the beginning,it was 50% of the oxygen in the mainland,but now,it is 56%,the value of which is 193,460,000RMB;The value of the protection of husbandry is 395,080,000RMB.The value of the protection of water and soil is 5,767,380,000.The total value of the benefit of ecology is 8,317,780,000RMB.Economical benefits:After the implement of the project, these farmers increased their incomes, the overall output of the grain and the livestock industry income is stable, the sowing area of the forest by-product is expanding, the portion of grain and the livestock industry income is decreasing, the income of forest by-product is increasing.Social benefits: After the implement of the project, farmers and herdsmen improved their Chinese understanding level by the publication of papers that with two launguages- Tibetan and Chines,and by the broadcast of turning farmland into forest policy.They provided them with indirect platform to learn.The project bettered the land use structure,and made the best use of the limit land;In the meanwhile,it also propel the surplus labourers tranfered from original work to out working which enhanced their incomes. Using CES production function model to turn out that the project for the economic growth to elasticity of substitution is up to 0.0256.On one hand, the implementation of Grain for Green Project in has been improving the ecological environment in Tibet, and has protected the fragile plateau ecology; On the other hand, it has also improved household's income of farmland farm, and promoted economic growth within the county and social stability and unity, moreover has made significant economic and Social benefits.In order to solidify the achievements of turning farmland into forest project,this article suggests that we should increase the government's investment to Tibet and support the construction of infrastructural facilities; strive to develop later industry;improve local residents'scientist quality;further perfect the mechanism of ecological compensate to consolidate the result of turning farmland into forest.
