According to the Fourth Assessment Report of IPCC, deforestation accounts for 17.4 percent of global carbon emissions. The international community has become increasingly concerned about carbon emissions caused by forest degradation and deforestation, and REDD mechanism was also born in this context .On the basis of REDD mechanism, REDD + mechanism increased forest conservation, sustainable forest management and the content of forest carbon stocks, to make the mechanism apply in a more suitable space. As the most important measures to reduce emissions in post-Kyoto era forestry, REDD + mechanism has no more been questioned. China, as a developing country, is very fruitful in terms of forest protection. In order to ensure the implementation of REDD + mechanism in our country, we must integrate, improve and coordinate on the domestic legal system of forest to secure more funding of REDD + mechanism and ensure our initiative in the international climate negotiations.
