中国における森林資源の最適管理政策

―新疆ウイグル自冶区を事例として―

抄録

After the foundation of the People's Republic of China, a non-optimal deforestation has been put into practice. This enhances ecological problems like the depletion of forest resources, topsoil erosion, desertification, the decrease of biotic diversification, frequent disaster and so fourth. Under such cases, Chinese government took a series measures as “forest management policy”, “natural forest protection policy”, “making fields into forest policy” to develop domestic forest industry. Yet such management policies as protecting forest resources, important consideration of increasing forest courses are based on optimal management, the consideration from economic point is not adequate enough. The present study, by employing the case study in Xinjiang and from the prospect of forest resource management model, investigated the validity of expected standard of forest resource quantity and deforestation standard there from the economic prospect. The forest resources policy of planning deforestation standard implemented in Xinjiang has reached the control level that the optimal management of forest resources can be maintained sustainably, yet it greatly lowers from the optimal level. This study results showed that even if the planning deforestation is raised to the optimal deforestation, the sustainable resource level keeps its continuation.
