The paper introduces background of CDM forest carbon sinks trade and advantage of Yunnan in this aspect,elaborates the significance in constructing carbon sinks trade institution based on CDM in Yunnan.

The actuality and potentiality of forest carbon trade market at home and abroad were expounded.

It also summed up the ideas and evaluation methods for forest carbon sequestration.

More and more attention has been drawn to forest carbon sequestration along with the further development of negotiation over the agreement of United Nations Framework Convention on Climate Change(UNFCCC).

Every countries attach great importance on forest carbon sink with the formal effective of Kyoto protocol.

Used incentive theory to analyze reasons that restrict development of forestry carbon sequestration project in our country.

The Kyoto-based forestry carbon sequestration market is not a basic pattern for forest ecological compensation,because its summation is limited and regulation is very complex.

Evaluation for the Carbon-Sink of the Forestry Project Involved in International Carbon Trade——Analysis based on the economic feature of forest carbon-sink;

This article analyzes the significance and the method of the evaluation of the forest carbon-sink,taking the artificial planta- tion of the Three-north shelterbelt forest system program as an example,uses the variable BEF (Biomass Expan- sion Factor) method to assess the value at the Three-north shelterbelt forest carbo.

According to regulations,forest carbon-sink projects under the clean development mechanism is an important type of project,since it provides an opportunities to the developed countries through the implementation of forestry projects in the developing countries to offset their some greenhouse gas emissions.
